2021 Chevrolet Silverado Complaint Log

Once I disengaged the auto stop on my vehicle, I would accelerate from a stop and I would loose my brakes. This happened several times. I took it to the shop and was told it was fine. Finally, one day I was descending on an overpass, disengaged my auto stop and my brakes were complete failure, even my emergency brakes, my check engine light engaged (the code read emissions issue). Was able to stop in a field, get it back to the dealership to find out I lost the master break cylinder but no indication on prior visits. The truck, check engine light will spontaneously start blinking but hold no codes. I have had it routinely serviced and it will overheat and oil will run hot but mechanics find no issues

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.

Loud ticking noise and power loss. Transmission shift slips from 2ed to 3rd .Recall to factory for check up. Said no problem? Changed oil. They say it was good. It is not.

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. No warning light was illuminated. The vehicle was taken to a local dealer, where the transmission was flushed due to a possible torque converter failure; however, the failure progressed. 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.

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

Throttle Body Failure Anti brake lock failure Throttle position sensor failure Power reduced *Vehicle has been to repair shop 3 times and the issue prevails. It poses a risk to my community because my loses power sporadically*

The contact owns a 2021 Chevrolet Silverado 1500. The contact stated that while driving at an undisclosed speed, the message that the rear seats were occupied and that the windows were rolled down was displayed, which required the contact to press the OK button. The vehicle was taken to the dealer where it was purchased, but no assistance was provided. The traction control and the ABS warning lights were illuminated while depressing the brake pedal. Additionally, the cruise control mode was inoperable. The contact replaced the brake pedal position sensor independently, and the vehicle was taken to an independent mechanic, who reprogrammed the sensor. The contact stated that after the repair, the brake lights erroneously illuminated while the vehicle was turned off, causing the battery to drain. The contact disconnected and reconnected the battery, which reset the vehicle; however, the failure recurred. The vehicle was not further diagnosed or repaired. The manufacturer was not contacted. The failure mileage was 110,881.

The truck started to vibrate badly. Brought it to the dealership and have to replace the 6.2 L engine. I was happy to make it home without it breaking down. The truck only has 67,000 miles on it.

On August 22, 2025 the malfunction indicator lamp (code: P146B Evap. purge pump) illuminated with no noticeable change. Ran codes at auto zone which stated engine failed and emissions not ready. August 25, 2025 drove to certified Chevy dealer dropped off vehicle and showed the service advisor the fix finder test results from auto zone as well as the illuminated indicator lamp (check engine light). August 26, 2025 picked up my vehicle with receipt stating "found dtc's P146b and P1467 stored in ECM (engine control module) for evap purge pump fault. inspected evap canister for any signs of fuel and none were found. replaced evap purge pump per special policy #N232395310. Cleared dtc and road tested vehicle to verify repair". September 9, 2025 my engine indicator light illuminated and my engine entered limp mode, a safety feature which reduces cylinder output/capacity. September 12, 2025 while in limp mode, I returned to the service dealer and informed them of the reduced power (limp mode) and my confusion as the second engine symbol that has been illuminated is in a different area than the first and my truck has ONE engine. (editor note: malfunction indicator lamp is for the emissions). My original transmission (8L90) was replace, because my vehicle was under power train warranty and the service advisor took it upon himself to approve the disassembly of my running, in good condition 8L90 transmission without consulting me or my approval. the 8L90 was "discontinued" for the 2020-2022 years without recall come to find out (sarcasm). I now have a new transmission (8L86-85) with the "special coverage" part (#N232395310) still connected, only now I have NO additional powertrain coverage for a new transmission, but the "special coverage" originally issued in 2023, BY MAIL, for 15 yr/150,000miles has extended two years plus mileage. (15 yr / 152,955) .The "special coverage" part should NOT affect the engine! Engines produce power/HEAT not CO2 . Sarbane - Oxley Act.

I was driving and all of a sudden engine and transmission failed many lights appeared on the dashboard brakes were not braking, the truck started to lose power and making weird noises.

The contact owns a 2021 Chevrolet Silverado 1500. The contact stated that while driving approximately 15 MPH, after making a left turn at a traffic signal, the rear wheels locked up. The contact stated that there was an abnormal screeching sound while depressing the brake pedal in a panic stop, and the vehicle jolted violently. The contact stopped the vehicle with the engine still running and observed the "Service Engine Soon" message displayed. The contact attempted to drive forward, and the rear wheels locked up. The contact was able to drive the vehicle to an Auto Parts store. The contact stated that a store representative used a handheld scanner and was able to retrieve DTC: P0747 (Transmission Valve Body #1 Open). The vehicle was not taken to a dealer or independent mechanic. The vehicle had not been diagnosed or repaired. The manufacturer was not informed of the failure. The contact researched online and related the failure to NHTSA Campaign Number: 24V797000 (Power Train); however, the VIN was not included. The failure mileage was approximately 140,000.

I have a Chevrolet Silverado 1500 with the 6.2L engine. I received the recall notice about the loss of propulsion due to a crankshaft issue. The safety of myself, family, friends and coworkers who ride with me on an everyday basis were put at risk because of the faulty engine. I brought my truck in for an oil change in August 2025. I had the Team Chevrolet dealership in Las Vegas Nevada do a telescopic inspection to see if my particular engine had the recall issue. It was discovered the engine did have the recall issue and was kept by the dealership for roughly two and a half months. Chevrolet has confirmed this is a major issue and is affecting roughly 600,000 people. There was no sign of the issue before the telescopic inspection but since the engine has been replaced I have now had three separate issues with misfiring cylinders on the new engine. The plugs and wires have been replaced twice and has not resolved the issue. When the misfires have occurred there were error codes, check engine light notification, and engine sputtering. This again has endangered the safety of myself, family members, friends, and coworkers who ride in my truck on a daily basis. This is now going on four months of issues that keep persisting and I am very concerned that both the manufacturer Chevrolet and the Team Chevrolet dealership are not taking the proper steps in order to solve this very serious issue.

General Motors is selling vehicles that are unsafe, unreliable, and unfit for consumers. My experience shows a clear pattern of negligence, misrepresentation, and disregard for public safety. On or about April of 2021, I purchased a 2021 Chevy Silverado RST z71 from Vetter chvrolet for about $56,000. GM promoted this vehicle as safe and dependable. Within the short 4 years of owning this truck, I faced major failures: engine issues, transmission problems and electrical malfunctions causing the parking break to engage on its own, at highway speeds of 70-80 mph on which nearly caused a serious accident, and failed Electronic Stability Control (ESC) system. This system helps maintain vehicle control, and a problem with it can affect braking, steering, and handling, Despite following GM’s maintenance guidelines, GM delayed repairs, denied coverage on certain failures, and left me with thousands in out-of-pocket costs. The vehicle remains unreliable and unsafe. For myself and my family, 2 children under 3 years old and one on the way. This is not an isolated issue—GM has a long history of recalls and defect cover-ups. These vehicles put lives at risk, cause financial hardship, and violate consumer trust. No one should fear for their safety in a vehicle marketed as “dependable.” This has impacted me by having : • Expensive repairs • Loss of transportation for extended periods • Ongoing fear of driving a defective vehicle with my family in it. Loss of use of my vehicle • Fear and emotional distress driving an unsafe product I have contacted GM and the dealership multiple times. Responses were dismissive, repairs were inadequate, and GM refuses accountability. Requested Resolution: Full reimbursement for all related costs Buyback (preferred) of the vehicle OR permanent repair at no cost Public acknowledgment and stronger quality control. Warning to Consumers: Think twice before trusting GM. Their failure to correct dangerous defects shows profits matter more than safety.

The 3 and 4 cylinder need to be replaced at 130000 miles with regulate maintenance always maintained

Transmission began shifting hard over between 60500 and 62000 miles. Dealership test drove and confirmed it was not normal. The transmission pan was dropped and contained metal shavings and bits. Dealer replaced transmission. During late February 2026, I began noticing some hard shifts again, but am hesitant to pay another $699 diagnostic fee and replacement transmission cost because I feel I am wasting money on a poorly designed and unreliable transmission. I don’t feel confident relying on this vehicle for transportation to medical appointments anymore.

The transmission shudders during light throttle at cruising speeds and low rpms, tachometer show continuous jumps in rpm and vehicle loosing power. No check engine lights. Concerned that transmission behavior can make the vehicle a hazard on highyways. Shuddering and hesitation on acceleration. Transmission fluid was changed at 70k miles and symptoms still persist. Current mileage 71k.

So many vehicles like mine have si.ilar issue. Lifter issues causing engine damage and other part damage. Causes issues at high-speed with power and stranded motorists on dangerous highways. It is a safety issue because you could be stranded in middle of highway. Lifter issues causing bent pushrods and other engine part damage costing . I had one pushrod covered, but others failed and now thousands in repairs. In expensive vehicles. Also towing charges, hotels, rental cars, etc... I dont want to be stranded again as only one bank was all replaced. The entire top half of the engine should be fixed and should be replaced and a service bulletin and recall should be issued to help.protect consumers.

misfire on cylinder #6 lifter failure on cylinder #6 bent push rod on cylinder #6 happened going down the highway at 75mph, luckily no one was injured local Chevrolet dealer did diagnostic and repairs repairs were covered by aftermarket warranty - $100.00 deductible no warning lamps or messages or other symptoms before hand

On August 10th 2025 I was driving down the 5 freeway to the airports All of a sudden I notice my check engine light is on. It was Sunday Chevrolet is closed so I got off the exit to go to auto zone in XXX. I stop at a red light my engine shuts off. I tried to turn it back on twice and it starts to smoke where the battery is. I have it towed to Chevrolet Fairfield. Where they figure out my ground wire came loose and shorted out. I paid for that to get fixed upon returning to get my vehicle on August 31, 2025 I drive not even 10 miles down the road and I hear a boom and then really loud clanking. I blew my engine. It was diagnosed with the same problems as other 6.2 gm motors. I have it towed back to Fairfield Chevrolet. It sat in Fairfield for a couple months due to me working out of town for work and the manager from Fairfield Chevrolet started giving me problems harassing me saying that if I didn’t get it off of his lot he was going to start charging me. So I had it towed from Chevrolet Fairfield to my house in [XXX] where it has sat since. I have been going back and forth with Chevy because I know of the recall however my vin is not in that recall yet it is the same problems as all the ones with the recall. I am really wanting to fix my vehicle as it has been almost 9 months. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Transmission is making rattling or ticking noise when accelerating , I'm getting hard shifting in 1st and 2nd and some random gears , I have been launched forward when coming to a stop , some hard shifting when kicking down to pass

When i first purchased the vehicle off the lot a few years back (its a 21, so probably in 22?) Brand new off the lot minimal miles. Within the first few months we started having issues with the power wanting to shift down. We took it in, the dealership found nothing wrong with it and cleared the codes. This happened a few more times. The last 2 times I took it in. They mentioned that there were recalls on it and could possibly be causing the issue. Took care of that (last august- have docs. to prove it as along with what they did and what we stated). Fast forward now 2 months ago (April of 25) and it starts acting up again and wants to downshift, shifting hard, stuttering and not wanting to drive, the same things we have been complaining about since beginning with lights on etc. However, this time we tried to shut it off and give some down time to get back home. After about 10 mins, we went to start the truck to get it home, and it would not start. We had it towed to the dealership. Once they got it, after 2 weeks of waiting we were finally presented with, the starter went out and the wiring box needed to be replaced (this has to be done before they can look into the original problem again) (because without those 2 things fixed, they wont be able to do) it is now June. I took the vehicle home, due to not having funds to fix right away. After doing some research and some digging, it would appear that the issues that we are having with the truck are issues that are already being recalled on this specific truck and model. However, for mine it is not, because I have the 2.7 l turbo and not the 6.8. THere have been numerous complaints about the known issue.(which i found out is the other wiring by the engine that is being chafed which is causing the wires to break and causing the other box and alternator to go and be replaced). If you replace it fries all again. Why is the 2.6 engine problem thats reported not recalled but rest is and it is known. I also see this online
