2021 Chevrolet Silverado Complaint Log

For the second time in my 2021 Chevrolet Silverado with a 5.3-liter engine, I've had GM lifter failure. It's directly related to the Active Fuel Management System (AFM), and was confirmed by my Chevrolet dealer's mechanic and service writer, Burdick Chevrolet in Cicero, New York, on both occasions. They've had to perform a multi-thousand-dollar lifter replacement service job. They've told me that GM is aware of the safety issues, but won't do anything about them. It also happened to me with my 2014 Chevrolet Silverado, but I was lucky that time. It was fixed with new spark plugs and wires. It's cost me thousands of dollars for repairs each time. But that's not why I'm reporting this to NHTSA. The issue is safety. When the lifters fail, you get no warning. The truck rattles and rumbles. It becomes unstable on the road, and sometimes wobbles as if it's about to go out of control. The problem causes the loss of electronic stability control (ESC) and renders the electronic parking brake useless. Lifter failure can also cause the engine to stall while driving, especially at a stoplight. This happened to me. I had to press the gas pedal gently to keep the engine running at a stop light just to get off the road. On the highway, when the lifters fail, the truck slows to a point where it cannot keep up with traffic. That presents a dangerous situation. It's not safe. GM knows about it, but as far as I understand, the company has done nothing to fix the safety problem. Internet forums are full of comments about the problem, the safety issues, and the enormous cost of repairs. Surely your agency can compel GM to fix the lifter failure problem before someone suffers a major accident due to an uncontrollable vehicle. I'll never buy another vehicle with AFM. Many people are unaware of the dangers involved with this system. GM should get rid of it. [XXX] Skaneateles, [XXX] [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Truck is equipped with a 6.2 engine. It is a 2021 with less than 100k miles on it. Dealership is stating engine failed for no reason. Dealership confirmed engine failure this past week of April 2026. This is a known issue and my vehicle is not under the recall. Truck stalled out of no where. There was no warning before it did it.

On my 2021 Chevrolet Silverado 1500 Custom, I began noticing an issue around 79,000 miles where the vehicle did not come to a complete stop as smoothly as expected. Initially, I suspected the brakes, as I purchased the truck new and had not performed any brake maintenance up to that point. I scheduled an appointment with the dealership to have all four brakes replaced; however, upon inspection, I was advised that the brakes were still in good condition, with approximately 90% life remaining. I then completed a test drive with the shop foreman, who was able to replicate the concern to some extent and suggested that the issue may be related to the transmission. At this time, the dealership is in the process of disassembling the transmission to determine whether the issue can be resolved with a repair or if a full replacement is necessary. It is concerning that such a significant issue would arise at approximately 80,000 miles. Based on similar reports I have reviewed, this appears to be a relatively common concern within the 80,000–90,000 mile range. Additionally, this poses a serious safety concern, as the vehicle’s hesitation in coming to a complete stop nearly resulted in a rear-end collision while en route to the dealership. There have been no dash lights on.

When taking off it will sometime have hard shifts, shuddering, and acceleration hesitation. While driving, it will do static jolts. Dealer couldn’t pin point problem and advised for a new transmission or we could drive it until it dies. Dealer didn’t recommend to change transmission oil in fear of creating more damage.

Rough shifting in low gears, can be dangerous in intersections due to low acceleration ability. The check engine light is on for replacement of Transmission Valve Body Assembly.

The transmission has been having issues for the past couple days. It is the 10 speed model and I have noticed everyday for the last couple days that there is an unusual shifting pattern between 25-60mph. This is sometimes accompanied with a shudder that feels like going over rumble strips without the sound. The feeling is not constant, but I will come to a complete stop and under light acceleration it will return. Under hard acceleration it is not noticeable. However, I am concerned with the unusual shifting. It can happen at a constant speed where it will do a random shift up or down or under light acceleration it will feel like it’s slipping for just a second. The vehicle has 99,900 miles on it and there are no warning signs or lights active. The vehicle is about to be serviced to do an inspection to find the underlying issue. This is a safety concern because the vehicle could potentially cause more damage to the transmission and with the random shifting, could potentially cause an accident.

All of a sudden my check engine light came on with the sudden loss of power steering. Almost impossible to steer at low speeds. After turning it off I waited about 15 minutes then restarted the engine and there was no problem steering. Concern about it happening again in the middle of traffic.

The contact's father owns a 2021 Chevrolet Silverado 1500. The contact stated that while driving approximately 70 MPH, the check engine warning light illuminated. The vehicle started losing automotive power. The contact pulled over and turned off and restarted the vehicle, but the check engine warning light remained illuminated, and while the vehicle was shifted to drive(D), the vehicle failed to accelerate above 40 MPH. The contact stated that the vehicle was taken to a dealer who diagnosed the vehicle and determined that the lifters and cam shaft had failed and needed to be replaced. The vehicle was not repaired. The manufacturer was informed of the failure. The failure mileage was approximately 63,000.

Engine Temperature fluctuates. Check engine light comes on, prompt on dash will say engine is overheating. Engine fan stays on high. Code on scanner states Coolant Control Valve. GM has issued special coverage on this exact issue. However, they tell me my truck is not covered. I am very upset with GM as they are failing to address a known concern with my vehicle.

The rear wheels suddenly locked up while driving. It did it twice then the check engine light came on and then the transmission would not shift into gear until I turned off the truck and turned it back on. This happened 3 days in a row all while driving. Exactly the same. No prior symptoms or warnings before the incidents happened. The vehicle is currently at the dealership being inspected. There is a recall (N242454440) that addresses this issue but I'm being told that my truck is not covered under that recall because my VIN is not part of it.

The contact owns a 2021 Chevrolet Silverado 1500. The contact received notification of NHTSA Campaign Number: 25V274000 (Engine and Engine Cooling), and the vehicle was taken to the dealer, where the contact was informed that the vehicle had passed the recall inspection, and no repair was needed. The contact stated that while driving at 50 MPH, five months later, the engine seized in the middle of the roadway. The contact was unable to pull over to the side of the road. The vehicle was shifted to neutral(N) and pushed over to the side of the road with assistance. The vehicle was impounded by the local Police Department. The vehicle was then towed to an independent mechanic, where it was diagnosed, and it was determined that the engine had seized. The vehicle was not repaired. The contact stated that the recall remedy had failed to correct the issue. The contact related the failure to NHTSA Action Number: RQ26001 (Engine). The dealer and the manufacturer were not contacted. The failure mileage was approximately 125,700.

I was accelerating to 45MPH on a main road. My truck was running just fine. At about 45 MPH it felt like I hit a wall, and my truck started to rapidly decelerate and seemed to be downshifting very hard. A reduced engine power warning appeared in the message display, and the check engine light illuminated and began to flash. I luckly the car behind me was able to change lanes quickly and missed me and I was able to pull off the main road and turn off the truck. I let it sit for five minutes and restarted the truck. When I did, the truck seemed to drive at 25 MPH, and I kept it at that speed and was able to get it to my work down the road. When I got to work, my company's mechanic ran the code. A P2732:00 Transmission control solenoid valve 6 stuck off and P0700:00 transmission control module requested MIL illumination codes came up. We also noticed my truck no longer went into reverse and the engine would just rev and nothing else happened. I had the truck towed to the Chevy dealer who also got a P2732 error code. The truck as been at the dealer for the last two weeks and I have not told them to fix it yet.

The electronics freeze up and sometimes the stereo turns off and won't come back on. The transmission perks and then revs up then hits gear and kicks real hard. The transmission feels like it's going to vibrate out from under the truck going down the road at certain speeds!

I'm reaching out to hopefully prevent a horrific situation not only to myself or any other GM owners. My vehicle has been diagnosed with having a faulty transmission valve body. There are so many that have failed that the dealer cannot give me a time when the part will be available. Because my vehicle is out of warranty, they are not willing to help. When I looked online it said as of late 2024 there were at least 1,888 field reports were identified.

COMPLETE ENGINE POWER LOSS. I WAS DRIVING MY TRUCK TO WORK. I PULLED OUT TO THE DOUBLE LANE HWY TO MAKE MY WAY TO WORK. AS I WAS EXCELERATING UP THE HILL THE ENGINE JUST STOPPED, FULL POWER LOSS. PRIOR TO THE POWER LOSS THERE WERE NO WARNING LIGHTS OR ALARMS. ENGINE LIGHT WAS NOT ON. LUCKILY IT WAS EARLY IN THE MORNING AND THE ROAD WAS NOT BUSY. I WAS ABLE TO COAST MY TRUCK TO THE SIDE OF THE ROAD AND LATER HAD IT PULLED TO THE SHOP. I WAS TOLD THE ENGINE FAILED. THERE WAS AN ENGINE ERROR CODE P0016. I WAS TOLD THE ENGINE WAS SHOT AND WOULD BE BETTER OFF REPLACING. i WS ALSO TOLD THIS WAS NOT COVERED UNDER THE CURRENT RECALL. THE ESTIMATE TO REPLACE IS $9500. MY TRUCK HAS 93,XXX MILES ON IT. iT IS CURRENTLY AT VOGELS CHEVROLET IN KIEL, WI 53042

right bank collapsed lifter. this is the 3rd time in 5 years this has happened same side same lifter. loss of power engine shakes the whole truck. Also electronic emergency brake won't release automatically and engages when driving. This has happened when I first bought the truck in Mar 2021, again in nov 2024 and currently at antelope valley Chevrolet on Mar 20 2026 for the same thing.

The contact owns a 2021 Chevrolet Silverado 1500. The contact stated while driving at various speeds, the vehicle started shaking abnormally. The Service Electronic Stability Control (ESC) warning light, Parking Brake warning light, a wrench warning symbol, and the check engine warning light were illuminated. The vehicle was not taken to the dealer to be diagnosed or repaired. The manufacturer was informed of the failure and confirmed that there was no recall associated with the VIN. The contact was referred to the NHTSA Hotline to report the failure. The failure mileage was approximately 125,000.

On 03/13/26, I was taking a family trip when all of a sudden my 2021 chevy silverado (with 6.2L v8) began to lose power and shake uncontrollably causing me to make an emergency roadside stop. Fortunately, traffic was light and I was able to avoid a collision. I immediately heard a loud knocking sound coming from my engine and several check engine safety lights were displayed. On 3/16, I brought my truck to a local GM dealership and was advised that I needed a complete new engine replacement due to catastrophic engine failure because my rods and crankshaft had blown in my engine. The dealership checked for recalls on my truck but were surprised that my vin did not pull up a recall even though there was a recent major engine recall (# N252494000) issued for my exact model truck with the same issues my truck displayed. It should be noted that my vehicle had less than 24,000 miles on it and I have kept up with regular oil change and maintenance service and that before this issue I have had zero issues with this vehicle. To make matters worse my powertrain warranty expired 2 months prior to this incident so I am having to pay out of pocket over $12k for a new engine. On 03/19/26, I contacted Chevy but was told there was nothing they could do for me and stated that NHTSA would have to get my vehicle added to the recall. I am requesting that my vehicle and others like it get added to this massive engine recall so I can get reimbursed for my new engine and also to protect other families from possibly being involved in a major unavoidable crash. Thanks in advance for your help!

Random catastrophic engine failure Randomly made a clunk noise and oil pressure dropped to 0. Engine needs replaced

The coolant control valve failed and the repair resulted in an engine oil leak which persisted for 8 weeks and still has not been repaired. The service manager at the dealership and General Motors Company are trying to figure out how to fix it but are not able to yet. They may have to replace the engine is one thing the service manager said to us this week.

- What component or system failed or malfunctioned, and is it available for inspection upon request? High pressure fuel pump, lifter, and cam shaft failure. - How was your safety or the safety of others put at risk? Potential crash w/ kids in truck, loss of power, surging, engine damage, etc.. (fuel pump) Potential crash w/ kids in truck, engine seizure, severe engine damaged, metal fragments, loss of power, abrupt lock up, fire hazard, excessive noise, etc.. (lifter/cam shaft) - Has the problem been reproduced or confirmed by a dealer or independent service center? Yes confirmed by dealer Hiley Chevorlet, case # xxx w/ General Motors. - Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? Yes by service dealer Hiley Chevorlet, case # xxx w/ General Motors. - Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? No, no check engine light or messages. Bought the 21' silverado about 18 months ago, recently the truck began to sound and drive terrible, it was found to be a bad high pressure fuel pump, bad lifter, and damaged camshaft. Dealership acknowledged that these are common issues w/ this model & year of vehicle and the parts are defective parts that they use in the manufacturing process of this model. They deemed it was out of warranty range as it's still under year 5 however I exceeded the powertrain warranty by 10,000 miles so they will not cover the issues and damage.

The contact owns a 2021 Chevrolet Silverado 1500. The contact stated that while driving approximately 30 MPH, a message that the rear tailgate was open was displayed. The vehicle was stopped and inspected, and discovered that the tailgate had erroneously opened while driving. After closing the tailgate and driving away, the failure reoccurred. The contact stated that the failure occurred several times while the vehicle was parked. The cause of the failure was not yet determined. The manufacturer and local dealer were notified of the failure, but no assistance was provided. The contact was informed that the VIN was not included in NHTSA Campaign Number: 24V060000 (LATCHES/LOCKS/LINKAGES). The contact stated that the vehicle had experienced the failure listed in the recall. The failure mileage was 52,000.

I brought my vehicle to the dealership on March 7, 2026, to address the outstanding safety recall. However, I was informed that the recall repair cannot be completed until I first pay $1,100 to replace the idler pulley. Unfortunately, an unexpected $1,100 expense is not currently in my budget. It is quite concerning to continue driving a vehicle with a known risk of losing propulsion, as the increased risk of a crash is a significant safety worry for me. I would appreciate any assistance or alternative solutions you can provide to ensure this safety recall is resolved. Please find the message from the dealership: Additional Diagnostic recommendations: we are going to want to get the Idler pulley replaced 1st as it can cause unwanted noise and vibration during the testing with the Pico scope. after the repair take the vehicle on a good test drive get it good and warm Then retest the engine with the Pico scope and proceed with those test results. we still want to make sure it is tested correctly If the engine passes just note under Special Coverage N252494003 This special coverage covers if an engine failure occurs in the vehicle as a result of the condition described above for a period of 10 years or 150,000 miles (240,000 km), whichever occurs first, from the date the vehicle was originally placed in service, regardless of ownership."

When I started my truck, a "service power steering" error was displayed in my DIC. My power steering lost all control. After driving for 10 minutes and then shutting the truck off for about 5 minutes, the system reset. This looks very similar to the recall #N212333900, but 2021 Silverados were not included with the recall. This is the 2nd time it happened. The first time was in 2023. It's pretty scary when you can't steer without extreme exertion.

The contact owns a 2021 Chevrolet Silverado 1500. The contact stated that while driving approximately 65 MPH, the message "Service DEF System" was displayed and the check engine warning was illuminated. The message speed would reduce by increments of 10 to 15 MPH until the vehicle could not accelerate 5 MPH after driving 75 miles. The contact stated that a handheld scanner was used to retrieve DTC: P20B9. The contact stated that the failure was a recurring failure. The vehicle was taken to a local dealer where it was diagnosed and determined that the DEF tank heater module needed to be replaced. The contact stated that the dealer was aware of TSB: 21-NA-002 and 22-NA-150; however, the vehicle had a Salvage Title and was not eligible for the repairs. The manufacturer was informed of the failure and referred the contact to the NHTSA Hotline for assistance. The failure mileage was approximately 53,400.

2021 Silverado LTZ L87 6.2L V8 engine. 49753 mi. February 27th 2026 total loss of power when parking. A few weeks later hearing knocking noises coming from driver side engine area. this is my daily driver and need this issued fixed.

The contact owns a 2021 Chevrolet Silverado 1500. The contact stated that while driving at 35 MPH, there was a metallic sound as if a bolt had fallen inside the engine compartment and was rotating and spinning. The vehicle was taken to the dealer, where it was diagnosed, and determined that the camshaft and the engine lifters had failed and needed to be replaced. The vehicle was not yet repaired. The contact related the failure to NHTSA Campaign Number: 25V274000 (Engine and Engine Cooling) and NHTSA Action Numbers: EA25007 (Engine, Engine and Engine Cooling) and RQ26001 (Engine). The manufacturer was notified of the failure and referred the contact to the NHTSA Hotline for assistance because the VIN was not included in the recall. The failure mileage was approximately 116,000.

On 2-23-2026, while traveling at highway speeds on the freeway, the front upper and lower A-arms (control arms) suffered a complete structural failure. This caused an immediate loss of steering control, forcing the vehicle off the road. By sheer luck and reactive maneuvering, I was able to avoid a multi-vehicle collision; however, the failure resulted in over $4,000 in mechanical and body damage.

Master Brake Cylinder failed according to dealership. This however is the second time this issue has occurred. This system failure caused brakes to not respond correctly leading to risk of collision. My safety and my kid's safety was put at risk due to issue happening while vehicle was in drive. Part was initially replaced in April of 2025 and issue has occurred two more times since then in December of 2025 and February of 2026. Vehicle has been inspected by dealership multiple times but has not been fixed. Symptoms of issue included clicking sound when pressing brake pedal and becomes stiff. There were warning in the dash and lights: "Brake System Failure", "43MPH Top Speed", "Service ESC" and "Service Brake System". Along with Check Engine light, Brake light and Traction Control light.

The contact owns a 2021 Chevrolet Silverado 1500. While driving 43 MPH, the message "Brake Failure" was displayed. The contact then lost control of the vehicle, and the vehicle drove from the right side to the left side of the road, the vehicle drove off the road and crashed into a ditch before coming to a stop. The driver had not sustained any injuries. There was no property damage. The air bags did not deploy. The check engine, the ABS and several unknown warning lights were illuminated after the failure. A tow truck driver who was also a mechanic inspected the vehicle and informed the contact that the driver's side front suspension had fractured from the upper ball joint and the wheel was folded in underneath the vehicle. The vehicle was towed to the dealer, where it was being diagnosed. A Police Report was filed. The manufacturer was not notified of the failure. The failure mileage was approximately 98,000.

Warranty issue the p1098 code

UNKNOWN. I have had issues with my vehicle since the purchase. Very subtle in the beginning, then it became more noticeable. There was a recall issue with a valve in the operation of the transmission, this issue is now affecting the shifting into different gears. The other day a vehicle ran a red light and my wife and I were in the intersection. I tried to accelerate to get out of the way, but here was a delay before the truck's transmission engaged. Luckily it did engage and the collision was avoided. This is a serious issue, an issue that shouldn't exist, an issue that the manufacturer knew about. I would like someone to investigate this and hopefully, help me with this issue. [XXX] [XXX] . INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

P1098 engine coolant control valve Engine light comes on and truck says reduced power. Then went off. Back on again

I am writing because I have a truck with the 6.2L L87 engine and it has been burning oil at every start up and acceleration from stop signs or stop lights, it blows out a blue cloud of smoke. I have asked Jeff Belzers in Lakeville , Mn to look and they did not as my vin did not show up in the recall. I took it to Maur Chevrolet in Inver grove heights, Mn and they told me that my miles were too high and they did not do an oil consumption test. I am burning 2 1/2-3 quarts of oil every 3,000 miles. I called the GM customer service line and they said there is nothing they can do except note it, so if I do get it repaired and pay for it, I could possibly get reimbursed in the future. If there is a known issue with this engine and there being 3 different engine builders, than why is it that my engine doesn't fall under that recall. It has all the symptoms of the engine failure that is specified in the recall? And it started about 6 months ago. Thank you Sincerely, [XXX] P.S. I have 136,000 miles and the special coverage warranty runs out at 10 years or 150,000 miles. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

On February 12th, the check engine light came on in my 2021 Chevy Silverado 1500 with the L87 6.2 L engine. The following morning, I took it to the shop and had it checked. It was diagnosed with crank shaft bearing coming apart. I contacted the dealership and they told me that my VIN was not associated with the L87 recall, but that they would see if GM would be willing to help with the costst associated with replacing the engine. They agreed to pay for about 30% of the repair. I pointed out to them that my engine was manufactured in the Tonowanda, NY plant which is the site where many of the recalled engines were manufactured. They still refuse to cover the cost of the new engine. I feel that they should cover my costs since the engine was manufactured in the plant and broke down for the exact reason for the recall. My costs are over $10,000 due to their defective engine. Please add my VIN to the recall.

My 2021 Chevrolet Silverado, with approximately 84,000 miles, experienced a premature and catastrophic transmission failure while driving. The vehicle began to shudder severely and lost its ability to accelerate properly, creating an unsafe driving condition. I was able to get the vehicle to a dealership. The dealership diagnosed a complete torque converter failure requiring a full transmission replacement. Crucially, at no point before or during this failure did the vehicle's onboard diagnostic systems provide any check engine light or warning message. A sudden loss of power and transmission function on a highway is a major safety risk. I believe this is a widespread defect that needs to be investigated before it causes a serious accident.

A recall repair was performed on my vehicle at approximately 157,000 miles. Approximately 4,000–5,000 miles later, the transmission failed. The vehicle entered reduced power mode and became stuck in gear while driving. The dealership is recommending full transmission replacement but will not provide written explanation for why the failure is not related to the recall repair. I am concerned the recall remedy may have failed and that this condition poses a safety risk.

As I was driving my 2021 Chevrolet z71 pick up I had a warning light appear on the dash indicating the safety traction control system was faulty, at the same time my truck had a loss of power as if it was not operating on all cylinders. I could hear some strange noises that were not normal, at the same time my transmission was shifting abnormally. I managed to drive to a dealer and was told it was a collapsed lifter on cylinder #5 this occurred out of no where, I was informed what took place could have damaged the camshaft and I could be looking at a repair cost upwards of $5,000.00 and the service writer indicated this has been an ongoing issue with the 5.3 liter engine. My truck has been serviced at the dealership it was purchased from, and all oil changes have been performed within a reasonable window from when oil changes and service inspection has been recommended by General Motors.

The contact owns a 2021 Chevrolet Silverado 1500. While driving approximately 30 MPH, the contact heard an object being dragged underneath the vehicle. There were no warning lights illuminated. The contact pulled over and heard an abnormal clicking sound coming from the vehicle before the vehicle stalled. The contact was unable to restart the vehicle, and the vehicle was towed to an independent mechanic. The mechanic diagnosed the vehicle and determined that the engine had seized and needed to be replaced. The vehicle was not repaired. The contact researched online and related the failure to NHTSA Campaign Number: 25V274000 (Engine and Engine Cooling); however, the VIN was not included in the recall. The manufacturer was informed of the failure and referred the contact to the NHTSA Hotline for assistance. The failure mileage was approximately 100,000.

2021 Silverado tailgates often stop working due to a faulty, corroded electronic switch caused by water intrusion. A major 2020-2024 GM recall exists for this, which can cause unexpected opening. Check for corrosion in the tailgate switch/connector, a pinched wiring harness, or check for a blown fuse. This is the 2nd time my truck is at ganley Chevy in Cleveland Ohio. They already fixed 1 rotted wire due to corrosion. And now having same issue again that tailgate won’t open. They told me approximately 1000.00 to find and MAYBE fix the problem. This truck should be included in the recall as to it falls under the year of the issues and that it’s the same EXACT ISSUES AS LISTED Again they have my truck in shop and I feel my truck falls under the recall proximity of said items.

My vehicle has been at the dealership since February 4 due to a transmission failure involving the valve body, which is currently on national back order along with the converter. These parts are required to complete the repair, and the vehicle is not drivable. This issue occurred after previous major repairs, including engine lifter replacement and a CV axle repair. It has now been 71 days without a repair. The dealer has confirmed the failures, but the manufacturer has not provided a repair timeline or a definitive solution. I have not received consistent updates since March 19, and the vehicle remains out of service with no estimated completion date..

On January 3, 2026, I started the truck, but it would not go into gear when I put into drive; I then attempted to put into reverse and same problem. I had to have it towed to the dealership, McCluskey Chevrolet, Kings Automall, Cincinnati Ohio, on Monday, January 5, 2026, this is where I purchased the vehicle on May 14, 2022, with 16,594 miles at time of purchase (estimated), it was towed on a flatbed, and arrived at McCluskey with 60,072 miles. Truck was looked and they found that it needed a valve body. At which time they told me GM warranty expired, over 60,000 miles, really by 72 miles. Ok there is a powertrain warranty then I had to prove oil changes, guess what I'm human and I missed two oil changes so the "extended warranty" McCluskey "gifted me" was void. I then complained I only drove the vehicle 43000 miles and for a 2021 with 60,072 miles this is an issue. Service advisor then went to management and they reduce the cost from est. 4000.00 to 585.00 plus tax through a program that GM offers. Picked up repaired vehicle on 1/30/2026, 2/1/2026 engine light came on went to have a veriscan and it found solenoid 3 stuck off & solenoid 4 (the one that was replaced) stuck on. This is an issue on gas 2021 Silverado 1500 and I wanted to report my experience because this is not "primarily" a diesel problem any longer.

2021 Chevrolet Silverado Z71 Sherrod truck with the 6.2 engine came apart (blew up) driving down the interstate at 65 mph. Had truck towed to dealership and was told needed a new motor. Truck has 89,000 miles on it. I was told truck does not meet recall because of the date it was manufactured but was acknowledged that what happened to it is what the recall is for.

I just bought this truck off a used car lot certified dealer and I noticed the engine light on then the truck would hesitate to start and I know the battery is dying so I looked it up and I got a recall on 2021 Chevy Silverado just like mine just wondering why mine is not under recall or why won’t mine get fixed but everybody else is the same year in the same problems can get fixed. I think mine should be fixed.

The tailgate release switch is randomly operating, allowing the tailgate to drop. This has happened at highway speeds (from 55 to 75) and also while in park. I've had to pull over on multiple occasions to close the tailgate. This could allow items to fall out the back of my truck and possible strike other vehicles and their passengers at speed. The dealership has reported it can also drain the battery, which can jeopardize my safety as I am often in the backcountry in very cold temperatures and could be stranded. (Has not happened to me as of yet) This is a known issue that other Chevrolet 1500 trucks have been recalled for (in Canada) and other models of the Silverado in the US. My dealership (Fox Negaunee) stated that they have received numerous complaints on this issue but no recall has been issued for my vehicle yet. I have spoken with the dealership over the phone, but I have not brought it in until further information on a recall may become available. There are no warning lights that appear. This started happening about a month ago, and has continued since then.

The vehicle has an electric tailgate lock switch failure/defect. The tailgate unlocks on its own and pops open while driving, at stop lights, in drive-thru restaurants, and while parked which causes a safety hazard to the driver and passengers in the vehicle, as well as other drivers around the vehicle. Even after closing the tailgate, it will unlock and pop open on its own again. Then, I tested the closed, locked tailgate by shacking and pulling it open from the top edge which caused the tailgate to unlock and open on its own. This causes a thief risk of personal belongings and vehicle parts. There are no warning lamps or messages about the component failure. Since no recalls for the vehicle's VIN number are listed, it has not been confirmed by the dealer.

See attached document for complaint.

The contact owns a 2021 Chevrolet Silverado 1500. The contact received notification of NHTSA Campaign Number: 25V274000 (Engine and Engine Cooling). The local dealer was contacted but was unable to schedule an appointment because the service center was fully booked. The vehicle was not diagnosed or repaired. The manufacturer was not contacted. The contact had not experienced a failure.

Starting back in June 2025 Loss of engine power multiple times. Many times almost hit from behind as I turned onto a highway. Found out vehicle had a stop sale recall at the time of purchase and I had issues with back right tire. Took truck to a tire shop and learned that the wheel was welded in many places and fracture was visible. Finally, got the dealership to pay attention in October to my concerns. They were going to allow me to trade the vehicle out for another one while paying off the bank but that’s not what they did. They attempted the repair and tried to hand it back to me. 1/27/26 Was recently told this was corrected, and the sales person told me when he picked it up from shop he couldn’t go more than 30 mph. Dealership management told him not to tell me. I am submitting this complaint for immediate review regarding Ruiz Ranch Motors (Spring Branch, TX) for an illegal vehicle sale, prolonged withholding of my vehicle, misrepresentation of a “loaner” vehicle, and coercive threats involving law enforcement. This matter involves ongoing safety risks, financial harm, and improper dealer conduct affecting both myself and my minor child. Summary of Key Facts (Concise): • On June 25, 2025, I purchased a 2021 Chevrolet Silverado (VIN 1GCUYHET7MZ155657) from Ruiz Ranch Motors, financed through Ally Financial. • The vehicle was subject to a GM Stop-Sale / No-Sale Safety Recall (NHTSA 24V797000) at or around the time of sale. • I repeatedly raised safety concerns beginning shortly after purchase. These concerns were dismissed for months. • In November, Ruiz Ranch Motors took possession of my 2021 Silverado under the representation that they were “working on trade numbers” and a solution to correct the experience. Misrepresented “Loaner / Trade” Vehicle: • I was provided a 2023 Chevrolet Silverado, represented as a potential trade option, no trade was made (only dealership delay) this vehicle now has a engine light and no cooperation from dealership
