CHEVROLET Complaints

On September 27, 2025 while driving to my nieces soccer game my 2020 Silverado Traill Boss LT started losing power while driving. I was at a Red light when I felt the truck not properly responding to me pushing the gas pedal once it turned green. It slowly started accelerating and then with all the lights still illuminated on the dash, the truck completely stopped working with No response to the gas pedal. I had to let the truck coast forward while driving through an intersection. Thank God there was not that much traffic behind me and any cross traffic. I managed to pull the truck over stuck on the side of the road. My wife had to get a ride from a family member to reach the destination while I had to call a tow truck and have it towed home. Ironically, I believe the truck had just got out of Warranty, what a complete waste of thousands of dollars including the warranty that is always useless. I did not reach out to the dealership because I knew it was going to cost me an arm and a leg just for a diagnostic only for them not to find a problem. There was No Warning Light Flashing to notify me that my truck was taking a dump or any error code of any sort for a diagnostic to pinpoint the issue. I am surprised this has not turned into a Class Action Lawsuit (not yet anyways). My Father made me a Chevrolet person but with all the recent Engine/Powertrain problems with General Motors. I always believed the slogan "The longest lasting dependable trucks on the road". Tanks to YouTuber "@Donslife" for keeping the Public informed of all the latest updates with all these issues. This might be my last Chevrolet ever unless they could fix these issues and take some type of customer reimbursement/assurance/future or current incentives.

The vehicle has service driver assistance system warning. The seat vibration is not working and I believe there are issues with the sensor and or harness. There have been recalls on previous years of this vehicle for the same thing. There have been a wave of these lately, according to the dealership working on the vehicle. Parts availability is currently low because of this resulting in longer repair times. This is a key safety feature of the vehicle and must be repaired quickly. Unsuspecting users may expect warnings before collisions that may not happen.

2021 tahoe with 3.0L diesel engine and 139k miles recently began overheating when on interstate but temp would jump up quickly then quickly back down. Reduced acceleration mode is triggered and AC is turned off automatically. Diagnostic report shows coolant control valve error code and it was explained to me that valve is sticking then as engine pressure rises, it knocks it loose again explaining the quickly jumps and dips in temp. Fan runs constantly from moment it is started too. When looking for the part online to get an idea of repair cost, there was a bulletin about this being a known issue in the 2021 tahoes with the diesel engines and bulletin states GM extended special coverage for 15yrs/150k miles. When I called dealer to schedule service, I was told this bulletin doesnt come up under my vin number despite it having the same issues, error codes, year, make, model, and engine.

The contact's wife owns a 2024 Chevrolet Traverse. The contact stated that while his wife was driving 60 MPH, the brake pedal was depressed and went to the floorboard, and the vehicle failed to respond. The driver engaged the parking brake; however, the vehicle failed to respond. The driver swerved to avoid the vehicle in front, drove over an incline, jerked the steering wheel, and the vehicle eventually stopped. The message "Braking Module System Failure" was displayed. The contact stated that the incident was frightening for his wife and his two children, who were also inside the vehicle. The vehicle was towed to the dealer, where it was acknowledged that the braking system module and the parking brake had failed; however, no official diagnostic information was provided. The vehicle was repaired under warranty, and the contact was advised that the vehicle was drivable; however, the contact advised the dealer that there were safety concerns because the cause of the failure was not yet determined, and there was no guarantee that the failure would not recur. The vehicle was driven back to the residence, although the contact remained concerned. The manufacturer was notified of the failure, and a case was filed, but no further assistance was provided. The failure mileage was approximately 28,000.

I am reporting a manufacturing defect involving General Motors’ Active Fuel Management (AFM) system that caused catastrophic engine failure in my 2016 Chevrolet Silverado (VIN: [XXX] ). At approximately 78,000 miles, my vehicle experienced piston and lifter failure requiring full engine replacement. This failure occurred without warning and aligns with thousands of consumer complaints regarding AFM-related oil consumption, lifter collapse, and engine damage in GM vehicles. This is a known design defect that GM has addressed through Technical Service Bulletins and engine redesigns, yet many consumers continue to experience premature failures at low mileage. This defect presents a safety and reliability concern, including loss of power while driving and significant financial burden to vehicle owners. I respectfully request that NHTSA investigate this ongoing defect.

I have had replaced the valve cover 4 times already about ever 3 months or so and it is starting to chirp and act up by lagging and jumping on acceleration. My mother is [XXX] old and does not drive it hard or in excess. The 1st was in summer of 2024 the 2nd was December 2024 3rd was april 2025 4th November 2025 and it just started chirping again & its jyst now February. This is absolutely ridiculous. Ther are so many more things wrong with this car. Most of those are on the dealerships & their lies about this car are completely at fault; Unfortunately, they went out of business 2 weeks after my mother got the car. We found this news out when I brought it up to them to explain why her touch screen for the radio no longer responded.

I was unaware that when I purchased this vehicle that when the oil is low, the breaks go out and the break power booster shatters. The beaks have gone out on me 2x already and thankfully I’ve only had to replace the break power booster only once. Now once the oil is changed the breaks go back to normal, there is no grinding of any sort heard, so now going forward I pay real close attention to my engine, I listen and pay attention to the feeling and sound of the breaks, once the oil begins to become low knowing it’s time for an oil change around 40% is when I start to feel a bit of the difference in the breaks and I can feel a little bit of grinding, no oil light has come on at this time nor has the oil light or any type of signal has ever come on at anytime to let me know that it was time for an oil change. I’ve checked for recalls, I’ve checked message boards, mechanics have no clue about this problem, but at least my mechanic does now!

While driving at highway speed the panoramic sunroof/moonroof shattered/ imploded spontaneously sounding like a gunshot while driving on the highway. There was no debris or road hazard that caused it.

The Reduce Power to Engine keeps happening. It shuts my car down and lights up the traction control light, check engine light and its a serious hazard because I travel highway to and from work and its very dangerous when you loose power to your vehicle at high rates of speed. Also my emissions is bad due to a supposed fixed recall for the catalytic converter.

I am reporting a safety issue involving a Cybex Eternis S child car seat. The seat was manufactured on 02/28/2020 and has a printed expiration date of 02/25/2030, indicating a 10 year usable life. At approximately five years of use, the head impact foam failed and is broken into two separate pieces. The foam pieces are detached. This foam is a required safety component. Cybex customer service confirmed in writing that if the head impact foam is detached or broken into separate pieces, the seat does not meet safety requirements and should not be used. Cybex also confirmed that no replacement part is available and no repair or remedy is offered. As a result, the seat is unsafe and unusable halfway through its stated usable life, with no ability to repair or replace the failed safety component. This raises concerns about product safety support for child restraint systems marketed with extended usable lifespans.
