CHEVROLET Complaints

Sliding rear window leaking, causing mold and ruined seats. Had it "fixed" in 2023 only 3 years of owing it. Now here 3 years later the same issue is occurring and they're not willing to make it right. Mold causes a safety hazard for my children and anyone in my vehicle. My truck only has 30,000 miles on it and I shouldn't be having this issue

The vehicle is experiencing premature clear coat failure on the hood and roof. The affected areas show widespread oxidation, dulling, and breakdown of the clear coat, while vertical panels remain unaffected. This indicates failure limited to UV-exposed surfaces and does not appear to be normal wear. The condition is uniform across the panels and not caused by impact, chemicals, or improper maintenance. I have observed similar clear coat failure on other 2016 Chevrolet Malibu vehicles, suggesting a potential pattern or manufacturing defect affecting paint durability. The issue significantly impacts the vehicle’s exterior condition and resale value and continues to worsen over time. Photos are available documenting the condition.

I am submitting a formal safety complaint regarding an electrical system failure on my 2021 Chevrolet Silverado with approximately 61,000 miles. I brought the vehicle to Taylor Grubaugh Chevrolet of Waynesville after the check engine light illuminated. The dealership diagnosed a premature wiring harness failure caused by chafing. They also stated that this issue is known to affect multiple GM vehicles and is documented in Technical Service Bulletin 21 NA 149. Wiring harness failure presents a significant safety concern. A compromised harness can lead to erratic electrical behavior, reduced engine performance, stalling, or sudden loss of power while driving. With that the concern a possible vehicle malfunction or losing power in traffic came to light. The dealerships service department confirmed the problem, verified the wiring harness failure, & referenced the applicable GM technical bulletin. The vehicle was inspected by the authorized Chevrolet dealership. GM declined to cover the repair. No police, insurance, or other third party inspections have been conducted. Despite acknowledging that this is a documented & recurring issue across GM models, the GM informed me that the repair would not be covered under warranty or recall. At only 61,000 miles, a wiring harness failure due to chafing is not consistent with normal wear & tear & instead suggests a premature defect. Given that this is a known and documented defect, I believe it should be recalled. After further research, I discovered that this issue is far from isolated. There are more than 1,500 complaints filed with the Better Business Bureau and approximately 800 complaints submitted to NHTSA reporting the same or similar wiring harness failures across GM vehicles. The volume of complaints strongly suggests a widespread defect that may pose ongoing safety risks to consumers.

The contact owns a 2024 Chevrolet Silverado. The contact stated that while driving at an undisclosed speed and also while the vehicle was parked, a “Service Transmission Unable to Shift” warning message was displayed. The vehicle was taken to the dealer, where it was diagnosed that the PCM and the shifter had failed and needed to be replaced. The vehicle was repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 40,129.

When turning off the ignition, the key will not go all the way "off" and the key will not release. If I turn the ignition back on and drive forward and backwards and SLOWLY put the vehicle into Park, and then attempt to turn off the vehicle, it will occasionally allow it at that point. It appears to be a disconnect of the system recognizing the vehicle is truly in Park and when it isn't and thereby releasing the ignition off function. the engine does shut off but I think it remains in ACC and will not release. Maybe safety switch in the shifter assembly.

Having to have the torque converter looked into, 2nd vehicle in the last 2 years with what appears to be same shifting / shuttering problem!

2020 3.0 diesel duramax sucked in the antifreeze and caused a hydrolock. The dealer says that it is not covered under warranty since the engine was over 100k miles. They did offer a new engine for $30K which I declined. The truck was always well taken care of and only received the best in all products

MY BACK-UP CAMERA HAS NOT WORKED IN ABOUT 3-4 YEARS. THE SCREEN IS COMPLETLY BLANK. MY MECHANIC WILL NOT TOUCH IT AND I'M AFRAID TO GO TO THE DEALER BECAUSE OF THE COST. I DID NOTICE THERE IS A RECALL ON NEWER MODELS OF THIS VEHICLE.
