CHEVROLET Complaints

Water entered tailgate through drainage hole in tailgate cap. The water then dripped on the tailgate switch causing it to short out. This short circuit caused my tailgate to open and close randomly without pressing any switches or buttons or key fobs. May tailgate has a small ding it it now from where it kept hitting the wall while parked in the garage. I took the truck to the dealership to get repairs done and was charged 308.88 for the tailgate switch and diagnosis that should have been under a recall for this truck. Safety Recall N232426400 Tailgate May Open Unexpectedly issued May 2024. I called the customer service number [XXX] to try and get reimbursed for the repairs and they told me there is no recall on my truck. I had this problem and it clearly states the year, make and model of my truck in the recall, but because my vin wasn't included I'm out of luck? I will attach all the info i have on this matter. Any help would be greatly appreciated. Thanks [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I took my vehicle for an oil change to the Tracy Chevrolet dealership. I was informed that they detected a leak. I returned my vehicle on 4/28/26 for an inspection. My vehicle on has 59,297 miles. I was just informed that my timing cover located at the front of the engine has a leak and possibly the oil pan. After doing research, this seems to be a common issue.

Re: Vehicle Safety Defect Complaint – 2023 Chevrolet Blazer To Whom It May Concern, I am submitting a formal safety defect complaint regarding my 2023 Chevrolet Blazer. This vehicle has exhibited multiple system failures that present a serious risk to driver safety and public roadway safety. The vehicle was purchased new on July 20, 2023. Beginning on April 21, 2025, at approximately 27,610 miles, the vehicle developed a progressive defect initially presenting as oil-related issues. Despite multiple repair attempts, the condition worsened and required a full engine replacement in January 2026. Following the engine replacement, the vehicle continued to experience critical safety failures, including engine stalling, reduced engine power warnings, and electronic stability control (ESC) alerts. On April 26, 2026, the vehicle experienced a driver assistance system malfunction in which it attempted to steer off the roadway. I was forced to manually disable the system to maintain control of the vehicle. On April 27, 2026, the vehicle exhibited a fuel system failure, including fuel leakage and fuel odor, along with multiple simultaneous warning indicators: • Reduced Engine Power • Service ESC • Steering Assist Reduced / Drive with Care • Power assist driver system disabled This combination of failures presents both a fire hazard and a loss-of-control risk. Additionally, I was informed by the dealership that a high-pressure fuel line, a one-time-use component, was not replaced during the engine installation. This raises concerns regarding improper repair and continued unsafe operation of the vehicle. The vehicle has undergone multiple repair attempts and a major powertrain replacement, yet continues to present serious safety concerns. Due to these ongoing issues, I do not feel safe operating this vehicle. I respectfully request that NHTSA review this matter for potential safety defects that may impact other vehicles of the same make and model.

The temperature gauge on my 2020 Chevrolet Blazer stopped working and remains stuck on “cold” at all times. At the same time, the air conditioning stopped functioning properly and only blows hot air. The vehicle was taken to a repair shop where diagnostics indicated a faulty thermostat sensor. The thermostat sensor was replaced and the issue appeared fixed. However, less than two weeks later, the same problem returned. The temperature gauge again stays on cold permanently, and the AC blows hot air. This appears to be a recurring issue affecting the vehicle’s cooling system and temperature monitoring

While operating my vehicle under normal driving conditions, I experienced a sudden and complete loss of engine power without warning. The engine shut off abruptly in active traffic, creating an immediate safety hazard and increasing the risk of a collision for myself and surrounding motorists. Following the stall, the vehicle would not restart. The engine cranks but does not start (a “dry crank” condition). There were no prior warnings, indicators, or drivability issues suggesting an impending failure. This vehicle is equipped with the L87 6.2L V8 engine, which is subject to a known recall involving internal engine defects that may result in sudden failure. The symptoms and failure mode observed are consistent with reported cases of internal engine damage, including potential bearing or rotating assembly failure. At the direction of GM and the dealership, the vehicle was previously brought in for recall inspection. The recall was subsequently marked as completed. However, I am now being advised that the recall cannot be reopened and that I am responsible for the repair costs. A completed recall inspection does not eliminate manufacturer responsibility when the underlying defect later results in failure. I understand there is an ongoing and recently reopened NHTSA investigation into GM’s “Pico test” inspection process, as multiple engines have reportedly failed after passing this procedure. Given that this failure occurred after the recall inspection was completed, this incident raises concerns regarding the adequacy and effectiveness of the prescribed remedy. This event represents a serious safety issue due to the sudden loss of power in traffic without warning. I am submitting this complaint to document the failure and to request further review of the recall remedy and associated inspection process.

This vehicle has under 90,000 miles and is only used to transport my grandchildren to and from the local elementary school. We got in the vehicle, and it would not accelerate. The vehicle is currently at the Chevy dealership getting diagnosed, but the error message was for the transmission. We do not feel that this should happen on a vehicle with this low mileage and completely without any warning.
