CHEVROLET Complaints

My engine coolant temperature sensor failed. Replaced it and still not fixing the issue. This takes my steering assist away as they are all interlinked? I have seen on forms this is a common issue. This has the potential to blow up my engine, I’m not sure how this is not a recall with so many 2020-2026 blazer owners having the same issue.

Fuel line leak caused by design flaw in which line plastic fuel feed line (GM part #84200271) is installed too close to the undercarriage, causing it to rub against the frame due to vibration and wear a pinhole. This is known by gm in service bulletin Service Bulletin 17-NA-304. This is a fuel leak, that can causes significant fire danger to people, property, and nature. Eventually putting first responders at risk. Also the environmental risk of continuous leaking fuel. Luckily, I could smell it before anything bad happened. But if GM knows about this issue, it’s big enough they should do something about it and so should the NHTSA.

The rear window exploded and shattered while sitting parked in front of my house.

-My 2020 Trail-boss 6.2 Engine broke and stopped producing power and shut off, it is available for inspection and has been inspected by my local Chevy Dealer Tom Gibbs Chevrolet. -My son was crossing a railroad track and it shut off as he topped the tracks it shutoff at the tracks and he was able to coast down out of the way. If it shut off a second earlier he would have been stuck on the tracks and there is a list of what if's. My grandson in the car seat, my son gets out breaks his ankle and can't get my grandson out there is so many things that could have happened. -The dealer stated the 6.2 engine is known to have mechanical failures -The local dealer stated valve cover was removed and no movement in valve train needs new engine at a cost of $21,343.24 They realized that the original $250 rubber serpentine belt outlasted the engine with 123K miles on it -No warning lights, no rough running, no sounds just shut off no power.

The recall fuel pump module assembly It was replace July 2023 with part number Fuel Pump Module 84782007. On April 13, 2026 (33 months later) the car would not start, if it did start it was stall and die. When it also run rough if it would start, then die again. I had to have the car towed to the dealership. The dealership said the fuel pump module was out AGAIN! The exact same problem the first recall was suppose to correct did not solve the problem. At this time there is not a new recall on this matter. The part that replaced the original fuel pump module did not solve the problem. The replacement part appears faulty as well.

The navigation system and the one-pedal driving system started malfunctioning. The navigation system began displaying a different location during remote driving, causing it to send me down a street against traffic. This issue has never been resolved and continues unabated. Then, while on the highway, when I needed to slow down, the one-pedal driving system deactivated, causing me to almost collide with another vehicle. This has happened more than three times this month. GM and Chevrolet just keep saying they'll call me back to resolve the issue, but they never do, and they refuse to fix it.
