CHEVROLET Complaints

While driving my truck returning from a camping trip I received the following warnings in the dash: Service ESC, Service traction control, forward collision system unavailable. Check engine light was flashing. I made the assumption that the Check engine light was due to the warnings listed above. I continued to drive the vehicle until I began to feel a very noticeable shudder at idle, at low speeds, and also loss of power at higher speeds. The truck has the 5.3 ecotec engine with DFM. After researching the symptoms, I found that these symptoms are identical to the know lifter problem with that engine. The truck is a 2026 Chevrolet Silverado Trail boss with approx. 3454 miles on it. It's currently at the dealership waiting for them to "diagnose" the problem. I was told that it may just be a "faulty sensor", but after reading other people's experience with this engine I believe that the real problem is a damaged lifter/lifter pin due to the poor design and engineering of the DFM system

Vehicle experienced sudden power steering failure and needed to be towed. A list of preceding error codes presented upon diagnostic review including power steering motor circuit, control module power circuit low input/low voltage, steering failure mitigation, power steering malfunction, lost communication with power steering control module to name a few. Dealership traced it back to a known GM part issue with the body to chassis ground strap identified in GM consumer satisfaction program N252515590 in Chevy and GMC 1500 2019-2024 models. The identified strap corrodes causing electronic failure noted above and documented by the dealership. The CSP was issued in January 2027 and is in effect until February 2028 however the dealership charged my out of pocket $384.48 for labor for a $13.40 part. My GM platinum protection plan also refused to cover the cost of the know defective repair.

Tahoe failed mid driving in a public roadway, computer system said press to restart and car made a whirling noise. I was unable to restart or put into neutral to move. This was a safety concern due to it happening mid driving, and I had my two young children with me.

Component that failed: brakes. I was pulling into a parking spot at low speed and the brake pedal was suddenly extremely difficult to depress, almost impossible. It felt as if a brick were under the pedal but there was no obstruction. I was able to stop only because I was already going so slow. Safety of myself and others was at risk because I was almost unable to stop the vehicle. If I had been going any faster I don't believe I would have been able to without crashing into an obstacle. Vehicle is currently at a service shop but issue has not been verified or repaired as of today. When restarting the vehicle, the engine stuttered and started making odd sounds, and wouldn't idle properly. There were no warning lamps, messages, or other symptoms at all prior to failure. When I entered the parking lot it was working normally and when I turned to enter a parking spot the brakes suddenly just failed.

2022 SILVERADO ZR2 on second set of headlights due to extreme moisture inside of headlights and at night becomes a saftey issue due to the water distorting the beam of headlights. The headlights in it now are a year old

The turbocharger are bad on the 1.5 L vehicles. My current one , I had replaced already and my previous one had it too. Reduced engine power and should be recalled. I want to be reimbursed for the service and part replacement. 976.00 for the turbocharger and labor costs of 400.00. 3 1/2 hours of labor costs and the diagnostic test my nirth country GM in Hibbing. Should be recalled for all of these vehicles. 218-290-5027 Craig Johnson

Approx 5/19/26 Forward Collision Detection check light randomly came on when driving home and showed notifications showing "Service ESC" "Service Traction Control" then started showing notifications for the collision sensors unavailable and continuously flickering them across the dash. The Fwd collision symbol would come on and off randomly. Finally was able to take it to the dealership on 6/8/26. Dealership found 6 codes and updated the image processing module. The Fwd Collision symbol is back on and off, notifications are flickering across the dash more frequently and now the check engine light is constantly on as of 6/14/26. Car is currently back at the dealership. Pictures and videos were taken of the issue happening to provide extra proof and given to the techs. These sensors failing at any time could cause the vehicle to randomly brake, not brake, and possibly not register a potential accident and avoid it. This vehicle is our daily driver and is the vehicle my son's car seat is in so it's not just my safety, it's the safety of my wife and baby. It's the safety of anyone else who has this type of vehicle with these issues. Understandably it's always the drivers responsibility to pay attention to the road and surroundings but there's nothing the driver can do if the vehicle randomly shuts off or stops or slams on the brakes or another type of malfunction while out on the road. This vehicle has been in and out of the dealership 5 times now for three different things, every time it's picked up, the problem is still there or comes back within days. It's a pain moving all the baby gear back and forth, on top of the rentals we have been given have been so small, you can't even fit a stroller and groceries per-say in the trunk.

The contact owns a 2022 Chevrolet Silverado 1500. The contact stated that while driving on several occasions at various speeds, there was a clunking sound coming from the rear of the vehicle. The contact stated that on other occasions, while driving 65 MPH and above, the vehicle drove over a bump in the road, and the rear of the vehicle lost control and drifted into another lane. The vehicle was taken to a dealer, where it was diagnosed that the leaf spring pads needed to be replaced, and the rust protection was the cause of the leaf spring bushings cracking and separating. The vehicle was not repaired yet. The manufacturer was notified of the failure and offered to cover a portion of the cost of the repair. The failure mileage was approximately 25,000.

Odometer Fraud. The contact purchased a 2015 Chevrolet Silverado 1500. It was discovered that there was a mileage discrepancy. The vehicle was a dealer sale. The contact stated that the mileage on the title was discovered to be 214,850. At the time of purchase, the mileage was 139,131. The Carfax report mileage was not obtained.

DATE: 06/17/2026 The engine shuts off without warning while I am driving, recurring roughly every 10 miles. When it stalls, the dashboard and electrical accessories stay on, but the vehicle loses motive power, along with power steering assist and power brake assist, which is extremely dangerous at road speed and in traffic. This began immediately after dealer service completed on 6/18/2026. During that visit the dealer performed two safety recalls (N252494000, the "L87 Engine Loss of Propulsion" PicoScope inspection with oil change; and N252510321, ECM software reprogramming) and a valve lifter replacement that required removing both cylinder heads. The vehicle was running and fully drivable when I dropped it off, and was returned stalling repeatedly while driving. It never did this before the service. At first the engine would not restart after stalling. The dealer replaced the starter; it now restarts but continues to stall every ~10 miles. A dealer diagnostic scan recorded numerous "Lost Communication" codes across nearly all control modules, plus control-module input-power codes showing low voltage and power-circuit correlation faults (e.g., U3505, U3018, U3007) and an active loss-of-communication code for the power steering module — consistent with an intermittent loss of electrical power or ground affecting engine control. The engine passed the recall's connecting-rod/crankshaft (PicoScope) inspection, so this is not the recalled bearing failure mode. The vehicle is currently at the dealership and is undrivable. The dealer has ordered a new engine and apparently also a new radiator for reasons unknown. No crash or injury has occurred to date, but the vehicle lost power while on the freeway at speed multiple times. A GM customer assistance case is open. Repair orders and the diagnostic scan are available on request.
