CHEVROLET Complaints

My son was driving the car the Service Brake Assist message popped up on the screen, and the brake pedal went stiff. He was coming to a red light and had to swerve to the right to avoid hitting the cars in front of him as he had no brakes at this point. We had the vehicle towed to our house, had the vehicle looked at by our mechanic. The Diagnosis was the brake vacuum pump, part number #12684050 exploded. It is available for inspection, at this point we don't know if the metal pieces have fallen into the engine compartments and we would rather not replace the engine as well. We had contacted the Local Chevy Service dept. who said we can pay $1500.00 to for them to take apart the top of the engine to look for broken pieces, but the best option is to trade it in as soon as possible.

My 23 Chevy Tahoe was diagnosed with catastrophic engine failure on 04/02/2025, and per recall N252494000 a case for engine replacement. That replacement was completed and the case was closed on 06/02/2025. Since that time the new, replacement engine has been consuming oil at a high rate, is running with intermittent lag and I am waiting for a diagnostics appt with Chevy.

The truck lost power, starred sputtering and misfiring. I shut the engine down, restarted and was able to drive it home. This same issue occurred a couple more times but each time it was restarted it drove okay. I started doing research and found a history of this same issue being reported by other owners and upon complaining to GM, nothing was done. I stopped driving the truck and it has been sitting for 3 years now. On April 22 2024 I had the truck towed to Stingray Chevrolet to have the issue checked. I was informed that the engine was would need to be replaced at a cost estimated to be 18K. I had the truck towed back to my home and it has been sitting, until I decide what I am going to do. I have continued investigating and I have found where GM acknowledged there were engine issues that dated back from 2013/2014 more than 10 years where the same problems were reported. Several law suits were found to have been filed with some wins and some losses including class action suits. I wrote GM and asked them to step up, do the right thing and replace the engine. They refused naturally so I have been waiting, contemplating my actions but the fact still remains. GM built and sold defective engines back into the early 2000's and replaced these 5.3L V8's with another engine that there are still defects being reported. I would like for GM to fully replace the engine including all components and Auxiliary devices on my truck, at no cost to me. Give it another 100K mile guarantee and compensate me for the 3 years I have not been able to use my truck.

Odometer Fraud. The contact purchased a 2019 Chevrolet Tahoe. The contact discovered that there was a mileage discrepancy after the purchase of the vehicle. The vehicle was an independent dealer sale. At the time of purchase, the vehicle mileage was 135,000. It was later discovered, upon checking with an OBD2 Scanner, that the mileage was 220,145. In addition, upon checking Carfax, the mileage was 134,426.

This complaint is submitted as additional information related to a previously filed safety complaint for the same vehicle and incident. Since the original submission, General Motors Product Assistance Claims verbally denied responsibility, refused to inspect the vehicle, refused to provide written confirmation of their denial, and ceased responding to emails and calls. GM previously instructed me not to repair the vehicle and promised a rental vehicle and tow, neither of which were provided. The vehicle remains unsafe to drive due to smoke intrusion and shattered rear glass and has been left exposed to freezing and rainy conditions. This incident appears consistent with a known rear window defroster thermal defect similar to GM Customer Satisfaction Program N192265660. GM’s refusal to inspect or mitigate increases safety risk.

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.

Odometer Fraud. The contact purchased a 2010 Chevrolet Malibu. The contact stated that while reviewing O'Reilly diagnostic report, it was discovered that there was a mileage discrepancy. The vehicle was a private sale. At the time of purchase, the vehicle mileage was 159,000, and the current odometer reading was 174,804; however, O'Reilly service report listed the mileage at 192,000.

I have a 2024 Silverado with the L87 (6.2) engine. I brought in in for recall. After inspection the Chevrolet Service Center said it was good. They changed the oils to 0-W40 per the recall. On January 8, 2026 I was driving at 35 mph and the engine just stopped. I had it towed back to the Chevrolet Service Center and after diagnosis it was determined that the engine failed and has to be replaced which take a month or more.

My truck has the 6.2l engine, prior to me buying it in September 2025 with 27,000 miles it had its engine replaced due to the recall/engine failure, then after 6,000 miles on 12-30-25 the 2nd engine it has had failed and had to be replaced. This truck that only has 34,000 miles is now on its 3rd motor and leaves me worried to really travel with it due to wondering if I am going to be stranded again.

Dear Sir or Madam, I am writing to formally report a safety-related defect involving the power unlatching tailgate switch on my Chevrolet 1500 truck and to request that this make and model be added to the current safety recall affecting Chevy HD vehicles. The power tailgate unlatching switch malfunctioned and would repeatedly attempt to open and close the tailgate while the truck was parked. On one occasion, this occurred continuously overnight. The following morning, my key fob was completely unresponsive, and the truck had zero battery life. The battery would not accept a charge, and the vehicle had to be towed to the dealership. Upon inspection, the dealership confirmed that the battery had been fully depleted and permanently damaged due to a short in the power tailgate switch. The faulty switch continuously drew power as it attempted to actuate the tailgate, ultimately destroying the battery. This failure created a serious safety and reliability concern, leaving me stranded with a completely inoperable vehicle. Given that this issue resulted from an electrical short and caused total battery failure, I believe it represents a significant safety defect. Based on the similarity to issues addressed in the current Chevy HD safety recall, I strongly believe this make and model should be included in that recall. I respectfully request that this matter be reviewed and addressed to prevent other owners from experiencing the same hazardous situation. Thank you for your time and attention to this matter. I look forward to your response. Sincerely, Charles Senn
