2021 Chevrolet Silverado 1500 Problems

The truck shut down while on the highway, complete loss of power and would not restart. Chevrolet dealership concluded that the engine has locked up/failed. Chevrolet states that 2021 6.2-L L87 engine is not included in Recall 25V-274 despite similar mechanical failure.

internal engine failure: Lifter went out. Hence caused a catalytic converter to fail without my knowledge. Obviously with this issue there is an issue and can potentially be more. This would be under a recall.

See attached document for complaint.

While driving approximately 30–40 mph through an uphill left-hand curve, the steering suddenly became extremely stiff and very difficult to turn. I do not recall seeing any warning before I noticed the steering becoming stiff. While trying to control the vehicle, I noticed “Service Power Steering” and “Service ESC” warnings approximately 1–2 seconds later. I cannot say exactly when the warnings first appeared because everything happened very quickly and I was focused on trying to control the vehicle. The vehicle left the roadway onto an adjacent lawn and traveled along a steep hillside beside the road. The driver-side mirror struck a curve sign and broke before the vehicle returned to the roadway. The vehicle also bounced while traveling off the road, and there is additional visible body damage. I do not yet know whether there is hidden steering, suspension, underbody, or other damage. A passenger was in the vehicle and witnessed the incident. Shortly afterward, while taking the passenger home, the steering again became extremely stiff and I again noticed the Service Power Steering and Service ESC warnings. Because the steering problem occurred twice, I parked the vehicle and have not driven it since because I do not believe it is safe to operate. The vehicle has not yet been professionally diagnosed or repaired and remains available for inspection. I have opened a case with the manufacturer. There were no known steering problems before this incident. The vehicle had an alignment performed earlier the same day

2021 silverado engine failure. Yes it was inspected by a dealership and my extended warranty company and serviced by the dealership. Back on August 5th I experienced a misfire cylinder 3 and felt loss of power. On August 7th the dealership diagnosed both camshafts, 1 lifter, 1 valve, and 1 fuel injector was damaged and never received at warning lights or messages on the dashboard. I was without the vehicle for 39 days and within 10 hrs after picking up the truck i got an engine light on and several new codes on it and can not be driven and being towed. I feel these engines need a recall as it is well documented that these engines go between 60 and 80,000 miles and some a lot less than that, mine has 70,800 and went and now being towed with in less than 24 hrs after engine repair. I will be in contact with a lawyer to follow up on this matter.

While coming to a stop, a snap ring came off the brake master cylinder. Vehicle top speed was 40mph, with the parking brake automatically engaged. ***Note from mechanic: Vehicle has several brake faults, C05CC and C05CF master cylinder piston position sensor performance, C2A17 hydraulic brake sponginess, and C0277 brake pedal position sensor fault. Tech recommends Hydraulic Brake Unit replacement***

Turned from [XXX] into my street, about 9 houses down, i could not brake or turn steering wheel. Ended up hitting 2 cars, the problem was that the air bags did not deploy and the seat belt did not lock. truck was totalled.

On my way home to [XXX] from [XXX] around XXX, my 2021 Chevy Silverado with 84,xxx miles with the 6.2 L engine started to make a popping sound. I checked my dash for any error codes and there were none. The oil pressure, temp, and transmission temp gauges all read normal. I stopped and topped the gas tank off with premium gas and checked the oil level, which was good. I was able to limp the truck back to my house. The next morning when I started it, there were error codes and the engine was still making the popping noise as well as a louder knocking noise. I started researching the symptoms, called two local independent shops and concluded the DFM system that shuts cylinders off to conserve gas has failed and caused the lifters to fail. I was told the failed lifter could and probably did damage the cam shaft(s). If I kept driving it, the camshaft damage could cause complete engine failure and more safety consequences. One shop quoted $5000 to replace lifters and $8000 if the camshafts were damaged. The other shop was similar, but offered a rebuilt engine for $12,000 because the lifters, camshafts, and new GM crate engine were all back ordered with no ETA from the local Chevy dealership. After weighing my options, and needing a truck, I decided to trade in my damaged truck. I contacted the GM concierge on XXX and was told to call back when the dealership had my damaged truck and could diagnose it. On XXX I called them back and they said they wouldn’t help because I traded it in. I had no plans to trade it before the engine failed and took a substantial hit on the trade in price that GM should have helped with to cover their faulty DFM system that caused the lifters to fail, which the dealership confirmed was the problem. They said they wouldn’t know if the camshafts were damaged until they took it apart, which they decided to not do and send it to auction instead.

I was traveling on a 55mph road. My Chevy Silverado started to shake and lose propulsion. I pulled off on the side of the road. In idle it shook. The dealership was one mile to my south. I turned on the hazard lights and went to the dealership. I could only get the vehicle to 45mph as in shook very bad the whole way. It felt as if the engine was going to explode the whole way there. The vehicle was taken to the dealership where it has been initially diagnosed as a bad lifter.

According to 2 mechanics- including a body shop - the frame has prematurely rusted due to: TSB 19-NA-255 - Wax Coating on Frame Peeling, Metal Shows Corrosion/Rusting There's so much damage to a 2021 truck, that it may not survive this winter. The frame welds are breaking due to the lack of frame protection. I asked my dealership, Lamoille Valley Chevrolet 868 VT RT 15E HYDE PARK, VT 05655, on two separate occasions to check for damage. One time they made no report, the second time they told me it was normal wear and tear. I've been told trucks 20 years older than mine, are in better condition. There was no protection for this frame.

Statement for NHTSA Subject: Safety Complaint – 2021 Chevrolet Silverado Unexpected Jerking/Harsh Transmission Engagement I am submitting this complaint regarding my 2021 Chevrolet Silverado 1500 2.7L Turbo with approximately 128,000 miles. My vehicle has developed a recurring problem involving harsh/jerking transmission engagement, hesitation, shuddering and abnormal shifting. The truck can jerk when engaging or changing gears and has also experienced a hard engagement when shifting from Reverse into Drive. During normal driving, the vehicle can hesitate or feel as though it is repeatedly fluttering/shifting instead of providing smooth and predictable acceleration. The vehicle has produced diagnostic trouble codes including P0700, U0100 and P0420. I am concerned that this condition could create a safety hazard, particularly if the vehicle unexpectedly jerks, hesitates or fails to respond normally when accelerating or changing gears in traffic. I am requesting that NHTSA document this complaint and review whether there is a pattern or potential safety-related defect involving transmission engagement, shifting or drivetrain control on 2021 Chevrolet Silverado vehicles. GM has published service information concerning delayed and harsh transmission engagement on certain Silverado applications, including 2019–2021 models, which makes me concerned that my vehicle may be experiencing a related issue. I am retaining my repair records, diagnostic information, receipts, videos and mileage/date information documenting when the problem occurs. I am willing to provide this information if requested. Please help me get my truck corrected, I love my Chevy Truck. Thanks Sincerely [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I was on the highway doing 70 MPH with my family driving down I-40 through western NC (mountainous terrain) when my brakes went out and the vehicle went into limp mode. I was able to safely pull over thank God and then had my vehicle towed to the dealer. The dealer just informed me that a software update is needed, and not covered under warranty. There are multiple safety bulletins coming out for related years and issues related to the braking system of this make/model and I would like this documented as well as Chevy to cover the cost of repairing this defect.

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

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

The contact owns a 2021 Chevrolet Silverado 1500. The contact stated that while driving 30 MPH, the rear wheels locked up, causing the vehicle to slide across the road. The contact was able to regain control of the vehicle and came to a stop in the middle of the road. The check engine and traction control warning lights were illuminated. The contact turned off and then restarted the vehicle and became aware that the transmission failed to shift into the intended gear. The vehicle was towed to the contact's place of employment. The contact who is a certified mechanic performed a diagnostic test and retrieved DTC: P0747, indicating a failure with the pressure control cylinder in the transmission. The contact also found information on NHTSA Campaign Number: 24V797000 (Power Train); however, the VIN was not included. The vehicle was not repaired. The dealer was contacted and confirmed that the VIN was not included int the recall. The manufacturer was not informed of the failure. The failure mileage was 83,830.

Window switch failed and I was unable to roll down the window. Dealer confirmed and performed repairs. Problem occurred on a dry day with no previous issues and the dealer stated it was manufacturing defect with the switch.

Rain is coming in through the back window. Dealer is stating that the rain is coming from the sliding window but satellite is stating it’s the brake light on the top of the truck.

I am submitting a safety complaint regarding a vehicle restraint system failure. I was involved in a collision with a deer. During the incident, the seat belt pretensioner activated; however, the seat belt did not properly restrain me. I experienced forward movement despite the pretensioner activation. The airbags did not deploy. Because pretensioner activation is intended to lock and tighten the seat belt during a collision, I am concerned that the restraint system failed to function as designed. This raises concerns about occupant safety and the ability of the seat belt system to provide protection in future crashes. I am submitting this complaint to document a potential safety defect and request review of this restraint system failure.“After reporting the seat belt restraint failure to General Motors, I was informed that because I was not injured, no action would be taken and no further review would occur.” Thank you for your attention to this matter.

The contact owns a 2021 Chevrolet Silverado 1500. The contact stated that while driving at various speeds, the vehicle jerked unexpectedly. The check engine warning light was illuminated. The vehicle was taken to a local dealer, where it was diagnosed, and determined that the valve body needed to be replaced. The vehicle was not repaired due to parts not being available and the VIN not being included in a recall. In addition, the part was ordered at the owner's expense. The manufacturer was made aware of the failure. The failure mileage was approximately 145,565.

While towing at night with horses, trailer lights started blinking on and off, eventually for longer periods, then stopped working all together. Research shows this is a common problem in GM vehicles related to the wiring and trailer light module. This is especially dangerous when pulling horses at night and all of the sudden lights go out. GM issued a technical service bulletin. This should be a recall...

A tire purchased new as part of a complete set failed on June 29, 2026, approximately 58 days after purchase. The vehicle was being driven on a smooth road surface under normal driving conditions when the tire suddenly failed. There was no known impact with a pothole, curb, road debris, or other road hazard before the failure, and there were no warning lights, messages, or noticeable symptoms indicating a problem with the tire before it failed. The sudden tire failure created a serious safety concern because it occurred while the vehicle was being driven and could have resulted in loss of vehicle control, a collision, or injury to the vehicle occupants or other motorists. Because the failure occurred while traveling out of state, the tire was taken to an independent tire service center for inspection. After inspecting the failed tire, the service center documented that the tire had separated internally and determined that the failure was due to a manufacturing defect. Written documentation of the inspection findings was provided. The failed tire was later taken to the selling Goodyear location for inspection. Goodyear disagreed with the independent inspection and claimed that the failure resulted from a pothole impact. No pothole or other road hazard was struck before the tire failure. The failed tire has been retained and remains available for inspection upon request. The independent service center’s written inspection report, photographs, purchase documentation, and other supporting records are also available. 275/65R18 116T
