2021 Chevrolet Silverado Complaint Log

Rear power window has been replaced multiple times, each time it develops cracks and leaks water causing possible mold in the truck cabin.

The contact owns a 2021 Chevrolet Silverado 1500. The contact stated that while driving 55 MPH and depressing the accelerator pedal, the vehicle failed to respond as needed, and the vehicle lost motive power and came to a stop in the middle of a four-lane highway. There was no warning light illuminated. The contact was unable to pull over to the side of the road, and the vehicle failed to restart. The vehicle was towed to an independent mechanic, where it could not be serviced. The vehicle was then towed to the dealer, where metal shavings were found in the oil pan, and the contact was informed that the engine needed to be replaced. The contact stated that the vehicle remained at the dealer for a month, and the dealer was in the process of ordering the part. The vehicle was not yet repaired. The contact related the failure to NHTSA Campaign Number: 25V274000 (Engine and Engine Cooling); however, the VIN was not included in the recall. The manufacturer was notified of the failure and informed the contact that assistance would not be provided because the vehicle was purchased used and was not covered under warranty. The failure mileage was approximately 135,000.

The vehicle had originally stopped in a moving lane of traffic. It was towed to a dealership and the engine was rebuilt with a remanufactured engine. The engine idled rough and seemed to be misfiring. The check engine light kept coming on. The dealership stated the vehicle was repaired and I picked it up. The engine is worse. It idles rough like before. It is rough while driving and the check engine light continues to come on. I am about to return the vehicle for the third time before it stops in the roadway again.

I was stopped at a stop light and all of a sudden, the engine just revved amd revved and no drive only reverse, and it happened 4 times until tonight, 11/11/25 @ 8:38pm I am stuck at another red light and have to back my truck up to Home Depot and get a tow. Only a 5 year old truck with 71122 miles and ALWAYS WELL MAINTAINED WITH PAPERS AND GOES OUT ON ME. NOT ACCEPTABLE GM! You make things and used to be solid, like a rock trucks but now I feel robbed as a long time Chevy fan/enthusiast but I may have to change manufacturers unfortunately.

My engine on my 2021 Silverado 1500 with the 6.2L L87 engine failed, I took it to the dealer to repair and they quoted $4500 to fix it. I know these same engines are being recalled and GM is having to replace them, but they told me mines not one of the ones being recalled and the won't cover it because the warranty was up 5,000 miles ago. I highly doubt it's a coincidence, that mine failed after only 65,000 miles and it's not a manufacturer flaw. The vehicle is currently at the dealership awaiting repairs.

The contact owns a 2021 Chevrolet Silverado 1500. The contact stated that while driving at an undisclosed speed, there was a ticking sound coming from the engine compartment, and the vehicle lost motive power. There was no warning light illuminated. The contact received notification of NHTSA Campaign Number: 25V274000 (Engine and Engine Cooling). The vehicle was towed to the dealer, where it was diagnosed with crankshaft failure. The dealer discovered metal shavings in the engine oil and oil filter, and the contact was informed that the engine needed to be replaced. The replacement engine was ordered, and the vehicle was repaired. After the engine replacement, the contact stated that while driving at an undisclosed speed, the vehicle felt difficult to operate. Additionally, while the vehicle was parked and turned off, the vehicle failed to restart and lost motive power without any warning lights illuminated. The vehicle was inspected by an independent mechanic, who found that the metal bar located near the battery was very loose. The mechanic also informed the contact that due to the prior crankshaft failure, the transfer fuse box, starter motor, and battery had failed and required replacement. The vehicle was repaired. The contact stated that upon inspecting the replacement engine, the manufacturer’s sticker indicated that the engine was a remanufactured engine, and there was dirt and debris on the engine. The manufacturer was made aware of the failure. The approximate failure mileage was 48,650.

Vehicle was at a stoplight with the auto start button engaged on it. The vehicle completely stalled. All the power is drained from the car. leaving me stranded in the highway. I got it towed and when replacing the battery still nothing will roll over or even turn on.

Dealer says my vehicle is not approved to even check the motor out. Build date 6/21 6.2l motor under recall

Transmission shudders and slipping gears at only 100k miles.

The truck has 61000 miles on it I got it in August there is engine knock which sounds like a bearing might’ve went and now the rod is loose in there. There is a large recall already regarding the same make and model of my truck for this exact issue.

The contact owns a 2021 Chevrolet Silverado 1500. The contact stated that the vehicle had experienced several electrical failures, including the door locks erroneously unlocking and locking while driving, and occasionally, the ignition key could not immediately be removed from the ignition switch after turning off the vehicle, causing the battery to drain. Recently, the vehicle failed to immediately start after inserting and turning the key inside the ignition switch. The cause of the failures was not yet determined. The manufacturer was notified of the failures, but no assistance was offered. The local dealer was not contacted. The failure mileage was approximately 60,000.

Engine just died going 55 mph on a paved road. GM repair shop says engine needs to replaced. They originally told me my 6.2L engine was a recall, but my VIN didn’t show on database. Seems GM’s scope was not wide enough on their recall. I feel I deserve a new engine.

Vehicle: 2021 Chevrolet Silverado Issue: Infotainment system failure after GM‑pushed OTA update Description of Problem: On 10/31/2025, my vehicle’s infotainment system attempted an over‑the‑air software update. The update failed and the screen has been locked ever since, displaying only the message: “Update Failed – Return to Dealer.” As a result: - I cannot access any settings (clock, preferences, system menus). - All warning chimes and signal sounds (turn signal click, seatbelt reminder, back seat reminder, etc.) are disabled. - The backup camera still functions, but no other infotainment features are usable. - The system is completely unresponsive to reset attempts. I brought the vehicle to a Chevrolet dealer, who verified that it was the OTA update that caused the failure, they attempted a reflash but was unsuccessful. They now claim the entire infotainment unit must be replaced at my expense, even though the failure was caused by GM’s own update which I neither approved, initiated, or requested. My vehicle is out of warranty, but this was not a wear‑and‑tear issue — it was introduced by GM’s software. Safety Concern: The loss of audible warnings and chimes poses a safety risk. Drivers rely on these alerts for seatbelt reminders, turn signal confirmation, and other critical notifications. A manufacturer‑pushed update disabled these among other functions including radio, navigation, and all vehicle settings. Resolution Attempts: - Dealer attempted reprogramming on 11/6 (charged $295) but failed and state I need a new infotainment system. - GM Customer Assistance refused to provide goodwill coverage. - Vehicle remains stuck in failed update state as pictured. Request: I am submitting this complaint because GM’s OTA update disabled core safety features of my vehicle along with other basic features such as radio. I believe this is a manufacturer defect that should be investigated and addressed, regardless of warranty status.

The contact owns a 2021 Chevrolet Silverado 1500. The contact received notification of NHTSA Campaign Number: 24V797000 (Power Train), and the vehicle was taken to the dealer for the recall repair. The dealer informed the contact that the recall repair had been performed; however, the recall remained marked as incomplete. The dealer was contacted and confirmed that the recall service report had been sent to the manufacturer. The manufacturer was contacted and confirmed that the recall service report had been received; however, the manufacturer advised that the recall could not be marked as complete. The manufacturer did not provide further information. The contact expressed doubts that the recall repair was completed effectively. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair.

I experienced a locking up or no power to the rear wheels. It was raining and the rear wheels would spin. I had no traction. I had to take a few turns and had to be careful or I would have fishtailed into other vehicles. When I stopped at a stop light/or sign then proceeded forward the rear wheels would spin in place. The tires wouldn't grab the pavement. This is the best way I could explain it.

The contact owns a 2021 Chevrolet Silverado 1500. The contact stated that while driving 30-40 MPH, the check engine warning light and other unknown warning lights were illuminated, and the engine was running rough. The vehicle was taken to an independent mechanic, where the contact was informed that the vehicle could not be diagnosed due to a lack of equipment. The vehicle was then taken to Gary Sapp Automotive, where it was diagnosed with engine failure. The mechanic determined that the engine needed to be taken apart for the repair or replacement. The vehicle was not repaired due to the cost. The contact related the failure to NHTSA Campaign Number: 25V274000 (Engine and Engine Cooling). The manufacturer was notified of the failure and informed the contact that the vehicle was not covered under an extended warranty. The failure mileage was approximately 89,000.

My transmission started to make a rumbling sound intermittently while I was on the highway. It happened during normal highway speed and not dependent on acceleration or deceleration. I brought it to the dealership with 84,000 miles and they dropped the transmission pan. No metal found in the fluid. The issue was with the torque converter. I had my oil changed 1.5 weeks prior with a 21 point inspection. I was curious if there was a TSB for this issue. I haven't been able to find a recall notice for this issue.

GM 6.2 engine recently tested for the national recall regarding valve and lifter issues. Recall was cleared as ok, but they found burnt cylinders in multiple areas within the engines. Several issues are still occurring with this engine, and I think most are related to the recall effort. 1. Engine will use oil at an abnormal pace when towing anything heavy. Recently used an additional 2 quarts of oil when towing a trailer that weighed 10, 000 pounds over 1600 miles. 2. Recently engine seemed to lose compression at a stop light and turned off. This happened an additional 5 times until I could get the truck off the road and into a safe place. The engine would immediately start and then die within 5-10 seconds. Towed to a Chevrolet dealership and the service manager tried to move it into the bay for diagnostic testing. started and stopped 4 additional times as they attempted to drive if 100 feet into the service bay. Towed to my hometown dealer that afternoon for diagnostics testing. The next morning when they started the truck it cranked fine and has been running since (7 days). No lights appeared on the dash during the breakdown or warnings appeared in their testing I have spoken to several other Chevrolet owners about the 6.2 engine issues and what was occurring with my truck They also had seen an increase in oil usage when towing heavy. I believe that your investigation needs to delve further into not only issues with the lifter / rods but also into other mechanical concerns that are oil dependent and related such as burnt cylinders. This last issue occurred on October 27, 2025.

I’ve purchased my Chevy Silverado brand new and I’ve had to bring it to the dealership multiple times for code P1098 this will be the second time this has been repaired. Looking on line this is very common. This is the second time I have to leave my vehicle at the dealership and not I don’t have my vehicle.

I own a 2021 Silverado 1500 6.2 v8. Since October of 2025 this truck has been in and out of the dealership. First engine (Oct. 24, 2025) issue as my teen driver was on the expressway and luckily was able to get off and get safely to an unknown persons driveway. Then the motor seized and died as we tried to drive it home. A friend was able to tow it to our driveway and GM sent a tow truck to pick it up and haul to the dealership. The truck was in the dealership for 2 weeks prior to the first engine failure and "EVERYTHING WAS FINE". Nov 26, 2025 new engine comes in. December 12th SECOND motor was put in and FAILED as cylinder 7 had no compression. Dec 31, 2025 picked up my truck with the THIRD motor. Jan 14, 2026 took the truck back AGAIN for engine ticking, noise, loss of propulsion/speed, running sluggish. Dealer kept it until Jan 21, 2026. Dealer said they drove it and the noise is normal injector noise. They did nothing other than drive it. They will not investigate any further as it wasn't pulling codes or warning lights. It is still not running right and I'm waiting for it to have a major failure. It is not safe to drive. The first motor did not show any warnings either. GM really needs to get this figured out soon. No vehicle with 52,000 miles should have 3 motors put in it. This is not quality work and concerns for safety are real.

While driving the engine shut off without any warning lights which could have caused a serious accident causing bodily harm or property damages as I was unaware of the issue and was going 50mph at the time - this occurred on 10/23 I noticed a ticking and brought the vehicle to the dealer for inspection on 10/20, at the time of this inspection the technician said that they could not replicate the sound and I explained that this was happening at 3000 RPM. The technician said that I would need to bring the vehicle back and they would need to start to take apart my engine piece by piece and I said the ticking is part of the known lifter problem and the technician shrugged his shoulders offering no other options. That same day I took my vehicle to another independent shop and he confirmed the ticking is a known issue that occurs prior to the lifter collapsing. After the vehicle shut itself off, and I was able to restart the vehicle, many warning lights appeared on my dash, there were none there before, one of the codes that was flashing was ESC and the vehicle began to lurch and downshift. I called my mechanic who said the code was to do with the electronic stability control system but I should be okay to drive until I could get to him for him to look at the codes. On 10/24 I took the vehicle to the mechanic and another code was for Cylinder 3 misfire which he stated could be the collapse of the lifter and the codes will not clear. The vehicle now downshifts without warning, there is an engine knocking that is occurring and the vehicle is not safe to drive as the engine may seize at any moment.

The air conditioning only blows HOT air. The vehicle was inspected by my mechanic and states that the compressor and belt have failed and needs to be replaced. I realize that my 2020 Silverado is out of warranty, but after looking into this situation, I have found that GM has had known air conditioning issues with certain Silverado models, especially 2019-2021. I believe this is a widespread defect and should be covered and repaired through a goodwill program. I am bringing the Silverado for repairs to my mechanic on 10/31/25 as I live in South Florida and cannot continue driving this vehicle without air conditioning.

August 30th 2024 the pickup was just turning to roughly 30,000 miles and started a knocking sound. The GM dealership tore it apart and fixed what I believe they said was a bent rod. I cycled through two oil changes and decided to pull an oil sample. I sent oil sample off for analysis. The oil analysis came back urgent with very high levels of copper and lead showing in the testing. I then called the GM dealer and they had me bring it in. They did not send off any oil sample because when they pulled the filter, they could already see metal in the new oil. They had me call GM customer service because it is not part of the current recall. I contacted GM customer service on October 27, 2025. They gave me a case number 80392504. I was to bring it back to the dealership which I did. Again dealership called said metal was found again but GM will not do anything with it because it’s not under recall. They also told me that GM told them it is OK to have metal in the oil. I said well if it is OK to have metal in the oil I want to know what the test results show. Then I said, I want to know where the maximum allowance is. They did not know that. I said so it is an infinite amount according to them because there is no standard to check against. I said I’m not taking this in for a recall. I am bringing it in because I had my own diagnostic testing done. It failed. I drive back-and-forth to North Dakota and I told them this is very unsafe if that motor goes out and it’s -30 or -45 and my little boys in the back the heater is not going to work. That is very unsafe and deadly. When you have extreme temperatures like that, we cannot just be running around. Tell the engine blows up or locks up. I told them this needs addressed you don’t pay $82,000 for a vehicle and not get any support or care. I said if something happens to my boy, they will wish that they put a new motor in there or fixed it. They are playing God. They need their hand, slapped and do the right thing. Thank you

Like many others, I have been dealing with many issues with this truck. I have had repeated cooling valve failures, resulting in decreased engine power and constant cooling fan running at high speeds. Additionally, cranking issues with starting the vehicle.

Started with a clicking noise that mechanic thought it was the fuel pump but found out later it was the bearing is the rocker arms that failed and ruined the camshaft. Now it needs a new engine.

1st gear to 2nd gear are slipping

The following is a list of persistent electrical failures in my vehicle, several of which present a significant safety risk. I have attempted to resolve the issues: •Emergency OnStar Button Failure: My vehicle's emergency OnStar buttons consistently fail to function when the ignition is off. This is a critical safety defect, as the system is designed to work on a backup battery during an emergency, such as a crash. The system only operates when the ignition is on. • Excessive and Dangerous Floor Hump Heat: Following a service visit on October 2, 2025, the front floor hump became excessively hot, melting personal items and posing a fire and burn risk. •Fabricated Safety Warnings: The vehicle's computer system repeatedly displays false and misleading messages. Examples include an incorrect "new brake pads detected" prompt and a "taking your eyes off the road" warning that does not apply to this vehicle. These phantom messages are distracting and can cause driver confusion. •Persistent Connectivity Failures: The vehicle experiences frequent and consistent failures with its Wi-Fi and GPS systems, indicating a potential electrical or software malfunction. Numerous resets attempted by the manufacturer's technical support have not resolved the issue. • Computer Display Anomaly: the Chevrolet symbol appeared in red on the computer screen when the truck was started. The vehicle has repeatedly experienced spontaneous changes to the radio station and the air conditioning switching from cold to hot without driver input. •Unusual Decompressing Sound: When the vehicle has been sitting for an extended period, an unusual decompressing sound can be heard coming from the rear underside whenever a door is opened. Date: Software updates on January 27, 2025 and October 2, 2025. Diagnostic Test performed on October 2, 2025 that failed to resolve the issues. The OnStar buttons only works when the vehicle is turned on. I do have photos and videos available to support your claim.

My belief is a valve rotated and the cam shaft has defligrated to the point that the engine casing has been pierced. Chevrolet is saying I am not covered by the recall for my 2021 Chevrolet Silverado 1500

Auto tailgate would open and shut on its own, the rear tailgate button stopped working and then only the interior switch would work, Then after a month, the tailgate would not open and switch shorted out. Seems very similar issue as other chevys with water intrusion.

This is a recurring and random issues: 1. The "Stereo" shuts off and will take anywhere from a minute to 10 minutes to come back on. The issue is: a. This cuts out the use of hands free operation. b. It stops all use of GPS c.I can no longer use my cell phone to call in an emergency 2. The backup camera (which is the "Stereo") goes blank or dark on occasion. Cannot see to the camera for backing up anymore. 3. The "Stereo" stops responding, but still has power. This means the radio or music or whatever is still playing but I cannot turn it DOWN or OFF. Very unsafe that I cannot turn this off when driving, cannot hear sirens, etc. I have tried to have this addressed by Chevrolet. They "reset" the truck but I did not work. They want to replace the "stereo/backup camera/communication system" but cannot guarantee this will actually fix the issue. It is over $2000 to "try" this fix I contacted GM customer service and was told NO RECALL, NO RECOURSE

The track on the back glass is cracked and leaking water into the interior back cab light.

The contact owns a 2021 Chevrolet Silverado 1500. The contact stated that while driving at various speeds, the vehicle shuddered and hesitated while shifting into gear.

The vehicle was taken back to the same local dealer, where it remained for further investigation; however, no cause for the failure was found. The manufacturer was not made aware of the failure. The failure mileage was approximately 62,265.

Truck shudders when you try to maintain speed. The service engine light is on all the time. RPMs bounce up and down constantly. GMC dealership said it needs a new torque converter. It was $100 just to diagnose it!

The contact owns a 2021 Chevrolet Silverado 1500. The contact stated that the vehicle failed to start. The vehicle was taken to the local dealer, where it was diagnosed and determined that the battery needed to be replaced. The vehicle was repaired on two occasions, but the failure persisted. While attempting to open the trunk, the trunk failed to open. The manufacturer was not contacted. The failure mileage was approximately 500.

The contact owns a 2021 Chevrolet Silverado 1500. The contact stated that while her husband was driving approximately 60 MPH, the vehicle started shaking and lost motive power.

The vehicle was then driven to a local dealer to be diagnosed. The dealer diagnosed the vehicle and determined that the engine control module and sensors needed to be replaced. The vehicle was repaired. The vehicle was retrieved; however, while driving off the lot, the check engine warning light illuminated, and the vehicle started shaking violently. The vehicle was with the dealer. The dealer then diagnosed the vehicle and determined that two of the lifters in the engine 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 confirmed that the VIN was not included in the recall. The contact was referred to the NHTSA Hotline to report the failure. The failure mileage was approximately 70,000.

While driving at anywhere from 18–25 mph or 70–85 mph, my speedometer starts going crazy, the engine accelerates or decelerates, the speedometer shows random numbers, and you can hear and feel that the motor power feels different. Not all the times but is started to show more often

No reverse in transmission and sporadic engagement and shifting in forward gears.

See attached document for complaint.

2021 chevy silverado Engine was under the 6.2 recall On Sept 4 2025. The engine blew and the truck was taken to local chevrolet dealer. It had 38k miles on it. It stillf ell under the original powertrain warranty and the recall. Dealer informed me new engine was needed and ordered. It has been 2 months and the engine has not shipped from GM. 60 days is more than adequate time for this issue to be resolved. GM has made no attempts to make this right. Please help

I am filing a formal complaint regarding a serious safety concern with my 2021 CHEVROLET SILVERADO, following the completion of recall N252494001 performed by Galleria Chevrolet in Dallas, TX. Prior to this recall work and related inspections, my vehicle operated without any abnormal engine noise. After the recall inspection and a subsequent fuel injector repair performed by the dealer, my vehicle began producing a bottom-end engine noise that had never been present before, and ultimately we have catastrophic engine failure. What is highly concerning is that the dealership staff previously documented the situation in writing as follows: “We performed the recall inspection and the truck passed. After performing an injector repair now there is a bottom-end noise when it's running. Did the failed injector possibly affect the validity of the test? That may be the case. We know that the truck did not experience the noise before the inspection; is it possible that the steps we took affected the truck in a way that got the noise to show itself? That’s what we need to determine.” Despite this acknowledgment, the dealership is now denying any responsibility, classifying the damage as unrelated “wear and tear”. This reversal appears highly suspicious, as it contradicts their own observations and written notes. It suggests that the dealership and GM may be refusing to fulfill their obligations under the recall and repair warranty, leaving me with a vehicle that has a blown engine and a significant safety risk. Given the timing of the noise, occurring directly after recall work and injector repair, and the internal documentation from the dealership itself, I request NHTSA investigate whether: This issue is part of a broader trend affecting other vehicles under the same recall. GM and its dealers are properly honoring their obligations to fully repair vehicles impacted by recalls. Consequential damage resulting from recall work is being systematically denied coverage.

Truck has under 45k miles on it. After reaching 35-40mph, it began to shake and jolt. Once we drove approximately 20miles, the engine light began flashing, in addition to the parking break light turning on. The truck began to lose power and we were forced to pull over on the side of a busy road. After waiting a little bit, we were able to drive it to our local shop who advised us to tow it back the the dealership for repairs.

The transmission is making a clanking noise during the lower gears. The local dealer said the transmissions is "done for". The truck has around 125,000 miles on it. The truck is available for inspection. When checking for recalls, i saw the GMC were being recalled for the same issue.

ENGINE IS JERKY READ ONLINE ISSUES HAVE A LEMON LAWSUIT . THE DEALERSHIP SAID IT WAS AN 02 SENSOR IT DIDNT FIXED THE ISSUES
