2024 Chevrolet Silverado Complaint Log

I am reporting a safety defect involving a GM 6.2L L87 engine. My vehicle was included in the GM recall related to engine failure (loss of propulsion). The recall remedy was performed, and the engine was replaced under recall/warranty in August 2025. After the recall repair and engine replacement, the vehicle experienced a second catastrophic engine failure, on April 21st. The engine failed again while on a highway, resulting in loss of vehicle function and leaving me stranded. This occurred after the manufacturer had already attempted to remedy the defect. The vehicle has now been out of service for an extended period (approximately 2.5 months total across both events - and ongoing), and I am continuing to make payments on a vehicle that is not operable. This appears to be a failure of the recall remedy itself, not just the original defect. I am concerned this represents a broader safety issue involving post-recall failures of the L87 engine, as currently under investigation. I am requesting that this incident be included in the ongoing federal investigation into GM 6.2L engine failures.

Transmission- lost reverse and some forward gears too. Without any warning signs and no check engine light until hours after. It is going into the dealership on Monday (4/20) and this all happened on (4/17/2024)

Was driving the truck on the highway at 75mph when suddenly the motor revved up in rpm’s and vehicle lost all power. There was no warning lights or any limp mode or anything as such as far as warning. The truck lost all power and could hear metal to metal sounds and turned off the motor. I was able to coast the truck to an off ramp in 70mph traffic. The truck would not turn back on and vehicle was immobile, had to have the vehicle towed by a flatbed to a gm dealer near by. The dealer gave me a loaner pickup and hasn’t looked at my vehicle yet. I bought this pickup less then 3 weeks ago and the L87 recall and oil change had been done prior to me buying it. I was just happy that the truck didnt full shut down at that speed and cause a crash etc. Dealer said motor failure to me and couldn’t confirm a turn around time frame for my truck to get back to me.

While driving, the truck suddenly Boggs down and gets sluggish. A message appeared once that said reduced acceleration drive with care. It is dangerous because it loses power and stalls in front of other vehicles. I took it to the dealership on Friday the 17th and they said it was the crank position sensor. They ordered the part and I took it back on Monday the 20th and they replaced the sensor. Today, while driving down the highway it did the same thing again. I will be taking it back to the dealership tomorrow. The truck has 26,000 miles on it.

These are two separate incidents. The first one is the seat moves to the left or to the right given the direction of the vehicle. The other incident was when I was reversing into a parking spot. The gear shifted out of reverse and just was in a floating stage. I then had to put it back into reverse to continue it did it twice

On 04/16/2026, while driving, vehicle received and completed a software/firmware OTA update. A second update completion prompt was received while still in motion. Shortly after, while stopped at a traffic light, the auto-start/stop system re-engaged and the vehicle appeared to restart normally. Upon stopping to refuel, remote key fob auto-start failed to respond. Vehicle was started manually and driven to the next location. On arrival, remote key fob auto-start failed again. Used interior push-to-start — vehicle started but displayed an active Check Engine Light. Connected vehicle app diagnostic scan of the Engine and Transmission System returned two WARNING flags requiring service: - Transmission System — Schedule Service Now - Engine Electrical System including Charging and Starting System — Schedule Service Now All other scanned systems (Air Induction, Fuel Management, Engine Cooling, Throttle Control, Ignition, Variable Valve Timing, 4WD, Displacement on Demand) returned OK. Both faults appeared immediately following the OTA update. Remote start failure at two consecutive locations and the Check Engine Light activation are directly correlated in timing with the update applied on 04/16/2026. No fault codes have been pulled yet — dealership service appointment pending. This is not the first instance of an issue after updates are applied, between the infotainment system blacking out, rear camera or ADAS not functioning as well as sporadic crackling sound almost like electricity arcing in the engine compartment near the steering column

2024 6.2L Silverado Trail Boss, engine failure at 22k miles on 4/13/26. Dealer confirmed the failure (not sure which bearings seized since engine has not been torn down yet, was either crank or rod bearings) and ordered a new engine 4/14/26. I was driving on the interstate and the engine started lightly shuddering during acceleration, showing some loss in power and shifting oddly but no check engine lights and nothing too alarming to immediately pull over. After several miles of this, the engine started to emit a loud metal on metal squeaking/scraping sound when on the throttle but stopped when I would back off the throttle. About a mile later, the truck just shut off at 70mph and went to neutral as I was about to get off an exit to evaluate the issues. Dash said push button to restart as I was coasting, but it wouldn't restart so I put on my hazards and pulled to the shoulder of the highway. Once stopped, it automatically shifted to park and would not crank or allow me to shift to neutral. Flatbed was called and brought it to the dealer. Side note: The truck passed the Pico test 1/15/26 at 20k miles and was sent on my way with the thicker 0W-40 oil. Oil was changed every 5k miles and ran 93 octane.

I was traveling at highway speeds when the engine suffered a sudden and catastrophic mechanical failure without any prior warning lights or symptoms. The engine began knocking violently, locked up and put the truck into a brief skid before freeing up, followed by an immediate loss of oil pressure and a total loss of motive power.This sudden shutdown caused a brief loss of vehicle control as the power steering assist was compromised, creating a hectic and dangerous situation while I was surrounded by high-speed traffic. I was forced to navigate across multiple lanes to reach the shoulder. Crucially, this vehicle had the L87 Safety Recall (NHTSA Recall 25V-274 / GM Program N252494000) performed on July 8, 2025. The "remedy" provided by the manufacturer—which involved an oil viscosity change and a new oil cap—failed to prevent the catastrophic bearing/crankshaft failure it was intended to address. This represents a failed recall remedy that resulted in a life-threatening safety event. The vehicle is currently at a dealership awaiting a complete engine replacement.

Turning into the driveway and the truck shut off. Place in park and the truck started right back up.

On 04/03/2026 at approximately 0545 I was heading in to work . While at a complete stop I proceeded to accelerate on the Highway 54 BRF WI. 54615 when the truck made a clunking noise and jerked. At which point the engine light turned on along with reduced speed message across the display screen. unable to pull over safely at the moment I had to proceed no faster than 25 MPH on US 54 hindering all traffic behind me. once safely pulled over I placed the truck in Park, then neutral , which made a loud clunking noise and absolutely no reverse. Truck towed to local dealership. Vehicle had been inspected by Dealer tech. Tech stated faulty valve body in the transmission.

The 6.2L V8 motor is known to have faulty internals. I was driving down the highway and the motor shut off. The vehicle needs a new motor now. GM has offered an oil viscosity change to 0w-40. That was done 20k miles ago. This vehicle now needs a new motor

truck shut off while driving in traffic managed to steer it off the road, towed to dealership with p0016 code as well as a bunch of others. known recall issue passed gm pico test a month earlier. now when I log in here to view recalls it says 0 recalls not repaired. Now truck has to get a new engine.

Summary of Incident: On March 28, 2026, while traveling at 70 MPH on the Florida Turnpike, the vehicle suffered an instantaneous loss of motive power. The engine died abruptly with no warning. Upon reaching the shoulder, the electronic transmission locked, refusing to shift into Neutral or Park. The engine cranks but will not start. 1. Component Failure & Availability: The exact component is currently unknown, but the failure involves the Powertrain, Fuel System, and Electronic Transmission Control. The vehicle is currently at an authorized dealership and is available for inspection by the manufacturer or NHTSA upon request. 2. Safety Risk: The sudden loss of power at highway speeds created an immediate risk of a rear-end collision. Because the electronic transmission locked and would not allow the vehicle to be shifted into Neutral, it became a fixed object on a high-speed shoulder. It could not be pushed to a safer location, increasing the risk of a secondary accident. 3. Problem Reproduction: The vehicle was towed directly to an authorized Chevrolet dealership. As of this filing, the dealership is in possession of the vehicle, but the failure has not yet been reproduced or confirmed by a technician as they are awaiting formal diagnostic commencement. 4. Inspections: The vehicle was inspected by a roadside towing professional for transport. It is currently at the manufacturer’s authorized service center awaiting a formal diagnostic inspection. No police or insurance inspections have occurred. 5. Warning Symptoms: There were no warning lamps, "Check Engine" lights, or messages prior to the failure. No symptoms like rough idling or unusual noises occurred. The vehicle performed normally until the moment of total power loss.

I am writing to report a serious safety concern involving my 2024 Chevrolet Silverado that resulted in a child being locked inside the vehicle with the key fob present inside the car. On March 25 2026, after parking and turning off the vehicle, I exited the driver’s seat with my key fob inside my purse, which remained in the front of the vehicle. I then walked around to remove my daughter from the back seat. During that time, she climbed into the front seat and pressed the interior door lock button, locking all doors. My daughter has autism and is not able to follow instructions or unlock the vehicle on command. As a result, she was locked inside the vehicle with the key fob present inside, and I was unable to gain access from the outside. The vehicle did not prevent the lock from engaging, nor did it allow me to open the door despite the key being inside the vehicle. This situation required emergency assistance (911) to safely remove her from the vehicle. I understand that many vehicles have “lockout prevention” features; however, in this case, the system did not account for a vulnerable occupant inside the vehicle. Allowing the vehicle to be locked from the interior while the key fob is inside—and without any external override—creates a significant child safety risk. I am requesting that Chevrolet review this design behavior as a potential safety issue, specifically: - Why the vehicle allows interior locking when a key fob is detected inside - Why there is no external override to unlock the vehicle when the key is present - Whether a software update or safety feature enhancement can address this risk This is not just a convenience issue—it is a safety hazard that can lead to dangerous outcomes, especially for children or individuals with disabilities. Please confirm receipt of this concern and advise whether this issue has been previously identified or is under review.

1. Transmission shudder at highway speeds between 64 and 83 miles per hour. 2. Pour fuel economy; 12.5 mpg @ 65 mph, 11.8 mpg @ 70 mph, 8-9 mpg @80 mph towing a 2025 utility trailer wiith motorcycle approximately 1800 pounds.

Loud ticking sound from engine corresponding with engine speed (faster as the rpms increased). Took in to dealership out of concern and the rod bearings were spun necessitating a full engine replacement. This was only 4 months after it passed the inspection for Recall - L87 Engine Loss of Propulsion (Related field action: See Special Coverage N252494003).

What is happening with my vehicle is a major safety concern in my opinion for myself and for my family. I purchased the vehicle on February 18,2026 from Ryan Ford in sealy,TX with approx 32,800 miles. The first incident was on March 16 with 33,718 miles, my daughter and I went to leave the Lowe’s parking lot and my vehicle would not go in reverse. It however would go in drive, so after being pushed back out of the parking spot we left for our home.(this part of not going in reverse I do have on video) Once on the feeder road and up to approx 45mph my vehicle went completely out of gear and had to coast to a stop on the side the road. Turned vehicle off and on and it went back in gear, after making it home I made and appointment with the dealership and dropped it off that day. I was informed no codes came up and the dealership could not get the issue to duplicate so I received my vehicle back. The second incident was on March 21 trying to leave the convenient store, I put my vehicle in reverse and pressed on the gas to go backward and nothing happened. Then I pressed on the gas again and it threw my vehicle in reverse and jolted my truck back several feet before I could press on the brake. Luckily no one or no object was behind me. The third incident was on April 3rd trying to leave Walmart. My truck would not go in reverse again. I pressed the gas pedal several times and out of nowhere again it threw itself in reverse and jolted my truck back again. (I also have this on video as well).

The contact owns a 2024 Chevrolet Silverado 1500. The contact stated that while driving approximately 55 MPH, the vehicle started jerking and shuddering before it stalled. There was an abnormal grinding sound coming from the engine compartment. There was no warning light illuminated. The contact had taken the vehicle to a local dealer, where it was diagnosed and determined that the engine needed to be replaced. The vehicle was repaired. The contact researched online and related the failure to NHTSA Campaign Number: 25V274000 (Engine and Engine Cooling); however, the VIN was not associated with the recall. The manufacturer was informed of the failure. The failure mileage was 13,222.

Component: Faulty coolant control valve causing reduced acceleration and check engine light to come on. Fan is constantly on when reduced acceleration is displayed. Safety: can overheat, reduced acceleration can cause an accident. Problem reproduced: Dealer did check and confirm codes and errors. Dealer confirmed item failed. Coolant control valve needs to be replaced.

The tailgate has opened 4 times while I’ve been driving. There was one incident in which an object in the truck bed fell out onto the road. Other drivers are at risk for serious injury or death due to objects falling out. I have read other incidents of this happening online to the Silverado 1500 models however Chevy has only issued recalls for the 2500 and 3500 models. The problem has not been reproduced or confirmed by the dealer and they will be inspecting it in the next coming days. There were no warning lamps or messages indicating failure or that my tailgate was open. I’ve provided photo documentation showing me closing the tailgate as well as a photo of the object falling onto the road.

I had my oil changed and the next day the check engine light came on. I looked on the Chevy app to see what it was and it said Varuable Valve timing issue. I Click further into the app warning and it said, Engines equipped with this system use sensors that regulate the opening and closing of the intake and exhaust valves to optimize performance and efficiency. I live 3 and a half hours away fro. The dealership so I had some mechanics look at the truck just to see if they could pin point what the issues was exactly. They didnt pull or work on anything just looked around listened and plugged in a code reader. The code reader found some codes that had to do with 3rd stage valve timing issues and VVT. And 1 or 2 other codes. But they didnt know exactly what was wrong. I had my oil changed 1 more time to see if maybe that was the issue. It did not fix the issue. I called the dealership to make a appointment. I brought it in and get a call that the cam shaft need to be replaced. It was in the shop for about a month and when they said it was ready. I went to pick it up and as I was pulling out of the dealership parking lot. The check engine light came on and I drove back and it had the same codes. And now it is being worked on again. The safety side is if it looses power while im going 65 mph it could be really dangerous. Becaue there could be metal shavings in the oil possibly.

At just over 36,000 miles, the vehicle randomly started jerking to either side of the road. It's not continuous and happens at random intervals while driving. Sometimes the steering wheel would jerk with the movement of the tires, other times, it felt as if the steering wheel had disengaged for a moment. The first time it happened, we were traveling on a highway at 55mph and were jerked towards oncoming traffic. I immediately stopped the vehicle and turned around to head back home at a safer rate of speed. The steering issue continued numerous times until my arrival at home. This issue just happened today, so it has not been inspected by anyone yet. There were no warning lamps, messages, or other indications.

GM replaced engine after a complete failure associated with a defective engine recall. The remanufactured or new engine installed seems to have a similar defect as the original engine. Returned vehicle for service and was told GM refused to repair or replace the engine until the vehicle suffered another complete engine failure. Regardless of any safety concerns of an another complete engine failure.

I was driving down the highway and the vehicle suddenly shutoff without any warning. I coasted down an off-ramp and came to a stop in the middle of a round about. The vehicle would not re-fire and had to be towed to dealership. When at dealership it was discovered the engine failed. This is a 2024 6.2 liter engine that was not included in recall. I could have caused an accident on the highway as I suddenly lost power. People who were included in this recall received a 10 year 150K warranty on the new engine. My truck should be included in that.

The DEF tank failed making the exhaust system malfunction. This puts the vehicle in limp mode.

The dealership has informed me that the Radio Control Module of the vehicle needs to be replaced. The infotainment center which contains the backup camera is no longer functioning.

After taking in to dealer for recall diagnostics and higher viscosity oil change a couple months later. Heard a noise while driving on interstate, lost cruise control, stability system, engine light came on with a ECS. Kept driving on the interstate until we got to a red light and the engine died. Cranked starter but hard to start and ran rough and died multiple times. Feathered throttle to get over 1K RPMs to get it off the street. Towed to nearest Chev dealer. P300 code. Tore engine down. Here is what dealer documented: CUSTOMER STATES CHECK ENGINE LIGHT IS ON WITH SERVICE TRACTION & SERVICE ESC MESSAGES. ENGINE IS RUNNING ROUGH AND WILL STALL. TOW IN. Valve Spring Replacement - Replacing the faulty valve spring on the cylinder 7 exhaust side is necessary as it is causing the exhaust valve to remain stuckopen, leading to engine misfire and over 80% leakage in that cylinder. This service can help restore proper engine compression and improve engine performance. Op.1 CEL -CEL: Customer states 1. replaced the exhaust valve spring and valve spring seal. reinstalled components with new seals and cleared dtcs. started engine and verified the engine starts and runs but having multiple cylinder misfires. reset engine fuel trims and brought engine to operating temperature and let it run for some time. other cylinder misfires went away but still found a dead misfire on cylinder 7. removed and swapped spark plugs with no change. noted the spark plugs have some exhaust build up on the tip due to the faulty exhaust valve spring. performed a static compression test and found the compression to be 175 psi and a running compression test with a smooth build up to 125 psi. checked spark and spark was good. tested the injector system using the AFIT test and found the test to pass indicating no faults with the fuel injectors. performed a cylinder leak down test and found no cylinder leakage coming from cylinder 7. put engine back together and cleared dtcs. reset the throttle

On 1/31/2026, while returning from an AKC event with my XXX year old border collie, I was traveling on IXXX at approximately 70MPH in the left hand lane passing other traffic. As I started up a hill in a remote area, I began to hear a knocking sound coming from the engine compartment that sounded like a rod knocking and the truck began to struggle to continue up the hill. It then lost all power, a message stating to shift to neutral and restart flashed on infotainment screen, I shifted to neutral and pushed the start button, but everything went blank. I had to struggle to merge back into right lane and eventually over to the breakdown lane, approximately 5 miles from the nearest exit. I was forced to remain on the side of a busy interstate for approximately two hours during an unusually cold day for Florida that consisted of snow flurries while waiting for roadside assistance. Luckily, I was able to arrive at the dealership 5 minutes before closing and was able to get my truck checked in. The service writer knew exactly what the likely issue was when I described my ordeal, and it was partially confirmed when she pulled the Christmas tree of codes from the computer that my truck was throwing. It should be noted that the truck would not restart after the catastrophic failure that stopped the motor at 70MPH on the interstate and would not shift to neutral for the tow truck operator to load or unload onto flatbed. Subsequently, Techs determined that engine failed due to suspected internal damage to crankshaft and motor was replaced under warranty along with torque converter. The failed engine serial number was [XXX] but I was never notified or included in current recall 25V274, It did not show as active recall in GM App nor was it inspected during LOF visits at various GM Service departments. My truck was in GM service from 1/31 - 2/21 for the engine replacement, Mileage on 2024 Silverado 1500 High Country was 25,274 at failure. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Was driving 45 mph when a “ Conditions Not Correct for Shift” warning pops up on the screen and puts me into neutral, but came to a stop in a neighborhood entrance and have not been able to start or put the vehicle into gear

Transmission failed at 15000 miles. Attempted to shift to reverse and instead car went into neutral. Allowed me to shift into forward but quickly went into “limp mode” once underway. Seems like the same issue as many similar gm trucks have had with transmissions but my 2024 is not included in active recalls when searched by VIN. Suspect it probably should be since issue appears to be the same as those that are.

The cam crankshaft failed. I was driving on the highway at a speed between 65-75 and my truck just cut off without any warning. Luckily, I was in far right lane and coasted over to the side of the road but it was very scary because I didn't control my truck at all. I called the nearest Chevrolet Dealership that was Kevin Whitaker and they give me the Chevrolet help contact phone and they sent a tow truck to pickup my truck about 1 hr later and I was stuck in my truck on the side of the road and I couldn't get out on the drive side because how close it was to oncoming traffic. Once I arrived at the dealership with my truck after asking the tow driver could I ride with him to the dealership. At the dealership they checked the truck with computerized device and the service advisor told me the truck code revealed cam shaft problems. I told him that I did see and warning sign saying low oil pressure once I tired to start up the truck again on the side of the road.

My truck engine stopped working while driving down the road causing me to lose power and I was not able to exit the roadway. There were no warning or messages until the loss of power and dash stated to "restart the engine". This was not possible. The truck was towed to a Chevy dealership and they confirmed the engine seized up do to unknown engine failure. This is a 2024 6.2L engine with 45000 miles that is NOT under recall. The dealership replaced the engine under the powertrain warranty.

My engine shutoff while I was driving on the highway. I had the initial recall remedy performed on my 6.2L 2024 silverado truck by getting the thicker oil about 8 month's ago. Now my truck is in the shop I'm suppose to be getting a replacement engine. I'm not sure if I can trust the replacement engine im getting.

I have a 2024 Silverado with the L87 (6.2) engine. I brought in in for recall. After inspection the Chevrolet Service Center said it was good. They changed the oils to 0-W40 per the recall. On January 8, 2026 I was driving at 35 mph and the engine just stopped. I had it towed back to the Chevrolet Service Center and after diagnosis it was determined that the engine failed and has to be replaced which take a month or more.

5449 miles. Motor had a knock. Took to dealership and they replaced valve lifters

Thrust bearing failure at 11,945 miles requiring complete engine replacement.

Vehicle simply died in the middle of an intersection and blocked the roadway for an extended period of time before being towed back to dealer. Engine failure confirmed, replacement has been ordered

Vehicle died and would not move forward or in reverse. The engine locked up and had to be replaced. Recall to test engine and replace with thicker oil was performed 6000 miles previous to engine failure.

Fuel rail pressure low during engine cranking

Formal complaint — persistent, non-disableable Bluetooth transmitter in [2024 Chevy Silverado] / privacy & safety risk; request for remediation and recall assessment I am writing to file a formal complaint regarding a safety and privacy defect in the infotainment/telematics system of my vehicle, a The unit runs Google Built-In / Android Automotive OS. This complaint documents technical evidence that the vehicle’s Bluetooth radio broadcasts a persistent, non-randomized MAC address and cannot be completely disabled via any user-accessible control. I request immediate remediation, a formal security assessment, and confirmation whether this condition will be remediated by firmware/OTA update or recall. Summary of the issue The infotainment unit’s Bluetooth adapter emits BLE advertisements that expose a static, permanent MAC address i.e ([AA:BB:CC:DD:EE:FF]) that does not change across power cycles and is visible to passive scanners while the vehicle is parked and otherwise idle. The vehicle provides no persistent user control to turn off the Bluetooth radio; menus do not disable the hardware radio. Attempts to disable Bluetooth via the system settings are ineffective. The static MAC and inability to disable the radio create an ongoing privacy and tracking risk: third parties can uniquely identify and track the vehicle across time and locations by logging the broadcasted identifier. This configuration is inconsistent with current industry cybersecurity & privacy guidance that recommends minimizing exposed identifiers, providing user control to disable wireless interfaces, and implementing randomization of wireless addresses when possible. The static MAC plus non-disableable radio constitutes a persistent, unique identifier broadcast in public spaces. This defeats reasonable efforts by consumers to limit tracking and to control their privacy.

Formal complaint — outdated Android/Google Built-In security patch level on 2024 Chevy Silverado; potential cybersecurity defect and negligent maintenance by manufacturer. I am submitting a formal complaint regarding a critical cybersecurity and software maintenance defect in my 2024 Chevy Silverado. The vehicle runs Google Built-In / Android Automotive OS with an Android Security Patch Level of February 2024 (as displayed under Settings → About → Android version). As of this writing in December 2025, this patch level is nearly two years outdated, with no available over-the-air (OTA) updates and no clear communication from General Motors or Google regarding continued support or end-of-life status. This condition exposes the infotainment and telematics systems to known and documented vulnerabilities, representing both a cybersecurity defect and potential consumer safety. Description of the defect: The infotainment system reports “Android Security Patch Level: February 2024.” Attempts to check for updates return “Your system is up to date.” The system shows a red exclamation mark beside the patch level, indicating a fault condition or known update gap. Neither the dealer nor OnStar/Customer Support can apply an update manually or clarify the support cadence. This leaves the vehicle permanently exposed to Android-level vulnerabilities discovered and patched long after February 2024. Security and regulatory implications: The infotainment system runs a network-connected OS with Bluetooth, Wi-Fi, cellular, and vehicle bus access. Unpatched Android components are subject to hundreds of known CVEs since February 2024 — including privilege-escalation, RCE (remote code execution), and Bluetooth/Wi-Fi stack vulnerabilities. The U.S. NHTSA Cybersecurity Best Practices for the Safety of Modern Vehicles (2022 update) and ISO/SAE 21434 require that manufacturers maintain timely security updates for all connected vehicle systems.

Truck was purchased Aug 2024 During first few months, I felt a shudder/vibration when either holding speed and/or slightly accelerating between 30-45 mph, usually at 1100-1300 RPM. Current Odometer 33,995 In the last month the truck has began to vibrate worse. I have a "Rumblestrip" feeling when at the same speeds. More noticeable on surface roads when following behind traffic at 30-45 mph. Generally the shudder is felt at approx. 1100-1300 RPM. Took the truck to the dealer yesterday, and they performed a quick roadtest. Service Tech was able to feel the rumble strip shudder multiple times, however their diagnostic tool only indicated a TCC Slip 2 times during a 20 min drive. The shudder/vibration happens when in "D". It is not present in "L9", or in "Tow Mode". The shudder feels worse in 4WD. If the shudder/vibration is happening, I am able to hold the speed and RPM at the current spot, the sensation is continuous and does not go away unless I accelerate or decelerate. I tend to feel it more when on an incline, and decelerating. As or right now the data has been sent to GM for diagnostic viewing. Found multiple TSB for issue with 2500/3500 models, and 1500 models from prior years. L84 Engine - 2024 Silverado 1500 RST

hard/delayed shifting, slipping, shuddering , like rumble strips at certain speeds. Jerking, bucking, or significant delays when shifting gears. Shuddering/Vibration: A feeling like driving over rumble strips, especially at certain speeds and when warm

Regarding Recall Repair on My Truck To Whom It May Concern, I am writing to formally express my frustration and concern regarding the recent service performed on my truck, which I purchased pre-owned from Tropical Chevrolet with only 4,700 miles. 9 months after my purchase, the vehicle received a manufacturer recall involving the motor, requiring a full engine replacement. I brought the truck to Bomnin Chevrolet West Kendall for the recall repair, expecting that it would be handled correctly and at no cost to me, especially since the truck was running perfectly before the recall work. After the motor was replaced, I was informed that the Air intake manifold currently on the truck is “not original.” This Air intake manifold was already installed when I bought the truck from Tropical Chevrolet, and I was never informed of any aftermarket or non-original parts at the time of purchase. Now, after Bomnin Chevrolet completed the recall repair, the truck has a check-engine light, and I am being told I must pay approximately $900 to change it for original air intake manifold to remove the check engine warning light. I think the mecanic took out the program.from the computer and Now they want me to pay.This is unacceptable for the following reasons: 1. The truck had no check engine warning lights and was running properly before the recall repair. 2. The Air intake manifold was already on the truck when I purchased it from Tropical Chevrolet. 3. I never approved or installed any non-original parts. 4. Bomnin Chevrolet removed and reinstalled the parts during the recall repair. 5. I should not be held financially responsible for problems created during the recall repair process. I am requesting that this matter be reviewed and resolved immediately by Bomnin Chevrolet West Kendall. The truck should be returned to me in the same conditions I gave it to them and the recall fix.Thank You Regards, Rafael Lafee

In May 2025, we received notice that my truck was involved in GM Safety Recall N252494000. In July 2025, a fuel consumption test was performed because the vehicle showed low oil pressure and was 2-1/2 quarts low. Chevolet indicated "consuming oil" was normal; however, I have owned trucks for 25 years and have never "consumed oil". In October 2025, we received notice that we could finally schedule the engine inspection at a Chevrolet Dealer of our choice. We scheduled this appointment for Monday, November 17th, 2025. The Picoscope Inspection was performed and the engine passed. They installed new higher viscosity oil, new oil fill cap and insert; but they note that the vehicle had no oil on the dipstick and would like to have another consumption test performed in 2000 miles. The next day, Tuesday, November 18th, 2025, the engine failed. The initial diagnosis was a continuous misfire of cylinder #3 requiring a Valve Lifter Replacement on Left Side. Upon completion of this work, they identified additional issues including spun crankshaft thrust bearing and damage crankshaft journal requiring replacement of the 6.2L engine. The engine failure occured the day after the proposed recall "fix" indicating that the picoscope test and higher viscosity oil is not an effective remedy. I brought up concerns about the consumption of oil multiple times with the Chevy Dealer multiple times and the response is "oil consumption" is considered normal with this engine. Not having my vehicle created significant hardships as I work in construction. I did not have a toneau cover to secure my tools, I did not have the ability to use my toll pass on the highway, I could load construction materials into the rental vehicle, and I had to switch between 4 different rental vehicles during the course of the 65-Day Repair!

The coolant control valve and the transmission control module are having to be replaced on thousands of Silverado 1500s from 2022 to 2025. Both parts have been updated, but there is no recall and many people are being left stranded due to this. Mine has not currently failed, but I am older and really don’t want to get stranded due to a known issue. Why wouldn’t they have been forced to do a recall General Motors should be replacing these as a preemptive precaution.

Per the dealer, catastrophic engine failure.

After engine blows due to recall and engine not running, it is impossible to shift the electronic transmission into neutral mode for towing. This happened to me in November of 2025 and I was recently told that I should report the issue. Neither the tow truck operator nor myself were able to get the vehicle into neutral without the engine running. I could have easily been stuck in the middle of traffic and no one would be able to help me move to a safe location. Some way of easily getting the vehicle into neutral without the engine running needs to be added to all Silverado’s with electronic transmissions.

Hairline crack developed on the transmission cooling line at the connection of the thermal bypass block. After looking up it seems to be common. Yes, there have been user-reported issues with transmission cooler lines leaking or cracking on 2024 Chevrolet Silverado models equipped with the 3.0L Duramax diesel engine, including at or near the thermal bypass block connection. These reports primarily come from owner forums and appear to affect a subset of vehicles, often discovered during routine maintenance or after noticing fluid spots under the truck. Symptoms can include hard shifting, fluid seepage on the undercarriage, or low transmission fluid levels, with some cases progressing to require towing if not addressed early. For instance, multiple owners of 2024 Silverado 1500 models (including ZR2 trims with the LZ0 3.0L Duramax) have described leaks originating from the cooling line block or thermal bypass area next to the oil filter, sometimes involving hairline cracks in the lines themselves.  In one detailed account, a 2024 model with around 35,000 miles experienced fluid leaking from the cooling line block, leading to replacement of seals and the entire line assembly due to cracking discovered after initial repairs.  Similar problems have been noted on closely related 2023 models, where leaks at the thermal bypass valve necessitated replacing the valve, O-rings, and all cooler lines, with some users reporting hairline cracks as the root cause.  Parts like the lines have been on backorder in some cases, causing repair delays, and resolutions are typically covered under warranty (e.g., powertrain coverage up to 100,000 miles), though repeated visits to dealerships are common. These issues seem tied to the 10L80 10-speed transmission paired with the 3.0L Duramax, where the thermal bypass valve can contribute to overheating or fluid flow problems if faulty, potentially exacerbating line wear

Engine burning massive amounts of oil, noticeable tick in engine, dealer request I bring it back every 500 miles for a total of 2000 miles to assess wether or not there’s a fault, when I requested for them to keep it diagnose it in their own way without forcing me to continuously have to return to the dealer (4 different times) for a conclusion
