CHEVROLET Complaints

I purchased this truck new in March of 2024, in May I was at a Starbucks drive-thru and lost all brakes. While slowing down at the window the pedal went to the floor and my dash light up like a Christmas tree. I pulled into a parking spot and shut the truck off for about 5 minutes. When I turned the truck back on the lights were gone and the truck seemed fine, so I drove home. The next day I was picking up my kids from school when in the pickup line the same issue happened. I lost my brakes, the dash lit up, and the truck started rolling forward in the pickup line. I had to push on the brake pedal as hard as I could to make the truck stop. I called the dealer and had the truck taken there. The truck was there for several days and I was told the master cylinder and brake control module were replaced. I’m reporting this now, because I saw that this is part of a larger issue being reported and I wanted my experience memorialized to help others.

The engine in my truck had a catastrophic failure (6.2 litre), same as the thousands with the same problem / failure. It had to be towed to the dealership where it underwent a complete engine replacement... it had 8,906 miles on it at the time of the engine failure. It died after making horrendous and loud noise, I was able to coast for a short distance but it came to a stop in the middle of a residential street and had to be towed to a safe location until the dealership could pick it up and tow it to their facility for diagnostics and repairs. I have the invoice with detailed information of the repairs and parts used.

Vehicle had large puddle of antifreeze under drivers front of vehicle. Antifreeze reservoir was completely empty upon opening the hood. There is an active drip of antifreeze under the car as displayed by placing a clean piece of cardboard under the vehicle. There were no indicator lights displaying a problem on the dashboard. Upon using an endoscopic camera, there is an active leak at the hose on the radiator. If I had not noticed the active leak, I would have driven the vehicle and overheated the engine with the possibility of seizing the engine. Vehicle is in service currently at Superior Chevrolet. There is a known issue under Special Bulletin N262546590 for the seal at the quick connect inlet on the radiator.

This vehicle is subject to Safety Recall N252494000 / NHTSA Campaign 25V274 for a known L87 6.2L V8 engine defect. Prior to the June 2025 recall notice, I incurred repair costs for the same defect at Schumacher Chevrolet, [XXX], on XXX ($405.63) and XXX ($2,755.76), neither of which resolved the issue. On XXX and again on 02/14/2025, the vehicle suffered total loss of propulsion on [XXX], once causing a missed professional licensing exam and requiring emergency roadside repair. The vehicle's engine replacement repair order remained open for 181 consecutive days (XXX) before GM authorized a full engine replacement under warranty. I submitted a written reimbursement demand to GM on XXX for $10,717.31 in documented losses under 49 CFR § 577.7. GM has not responded in writing and instead offered an unverifiable verbal credit of $3,000, which the servicing dealer has no record of. I am filing this complaint due to GM's failure to remedy this known, pre-notification defect within a reasonable time as required by 49 U.S.C. § 30120. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

ONSTAR module does not work. GM dealership claims the hardworking malfunctions and needs replacement for $800. Onstar is advertised as a safety feature that is now unable to be used.

My 2021 Chevrolet Blazer RS equipped with the 3.6L LGX V6 experienced catastrophic engine failure at approximately 90,200 miles. The vehicle had no prior warning. The dealer diagnosed the timing chain / lift/ cam damage. I am requesting investigation into whether this represents a safety or durability defect affecting other vehicles

Nearly new Chevrolet Tahoe in 2021 with less than 4,000 miles had an engine failure due to defective valve lifters that required a significant repair and lengthy out of service period (replaced valve lifters in one bank). Now in 2026 the same vehicle's engine has failed for the same reason and the engine needed to be replaced.
