Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“My son in law was driving the car with my permission and while making a left turn the vehicle stalled; there was no steering or brakes. The steering wheel locked up during the turn and caused the vehicle to continue turning on it's own and I proceeded to hit a pole. The radio and lights were still on during this time, however, the engine shut off.”
NHTSA complaint #10575594, filed 2014-03, 60,000 miles“I was on my way to work at an ongoing traffic on the interstate and my 2007 Trailblazer security and engine lights came on. It started to slow down and the engine completely shuts off. This is a known issue and happens multiple times before, I took it to the dealership service department they said they fixed it and I was charged almost $300 dollars unfortunately it did not fix. This is the worst vehicle I've ever had quality of the vehicle is suck. I will never buy Chevrolet again!!!!”
NHTSA complaint #10679398, filed 2015-01, 105,000 miles“Fuel sender/gauge does not function. I bought this 07 Trailblazer brand new and it only has 31k miles. Problem started to occur around 27k miles and the dealer advised it was not covered under warranty!!! You would think with 70 complaints about this same issue, chevy would do something about it!!! Very disappointing. I just wish that was the only problem...tire monitor doesn't work, the A/C electrical system failed, and the check engine light is always on.”
NHTSA complaint #10386547, filed 2011-03, 27,000 miles“The Trailblazer died when my wife and children was sitting at a red light and when she started it back the motor was making a loud knocking noise. She pulled it to the side of the road and called a tow truck and had it towed into a garage. The mechanic said that the engine was shot. There was no indication anything was wrong when it happened all the gauges were showing everything to be good there was no noise in engine or any warning lamps lit up on the dash. We had the oil changed just 2-3 weeks ago. We have only had the vehicle for 8 months. …”
NHTSA complaint #10457891, filed 2012-05, 94,000 miles“I read about: GM recalling 1.4 million vehicles for fire hazard by peter valdes-dapena, senior writerjune 9, 2010: 10:03 am et. While driving to work on may 17, 2010, I heard a loud pop and I immediately pulled over and called aaa. Approximately 10 minutes later, my 3 year old chevy Trailblazer had flames start shooting out of the hood. It was engulfed in flames soon thereafter. I thought it was steam, so if a nj firefighter had not grabbed me out of the vehicle, I am not quite sure how this story would have ended...”
