Example complaints

Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.

“The engine. The coolant low light stays on even though it isn't.. Have had it checked. They said its all ok. Then I read these complaints. Why aren't they being held responsible for a defect!!!!! Its their defect, not ours. We didn't sign up for $1200 in repairs or more!!! Are you getting paid to sit there and just put these up here to appease us? No wonder this nation is going you know where in a basket. Lack of integrity. My brakes also both went out completely when someone gave me less than a foot to stop when they pulled out of a parking spot downtown. …”

“Dt: 1999 Oldsmobile Silhouette. On august 11, 2005 the consumer was smelling gas; he looked under the vehicle and saw that the fuel lines were rusted. The mechanic at the dealership stated the fuel lines crumbled in his hands. All of the metal fuel lines for the vehicle had to be replaced. The smell was the only indicator. He checked under the hood first then crawled under the car and saw it was leaking gas.”

“I have had this vehicle since 3/99. In which time I have had to bring it back for transmission problems, electrical problems, leaking fuel injectors, brakes, non working cruise control which LED to the dealer replacing the compressor. Front end leaked anti freeze which LED to another major job. I am not a happy motorist here. The steering column squeeked. They greased it. Turned out there was a problem with the rackinpinion. I know something about cars and I know that for the amount I pay for this vehicle, I shouldn't be having these major problems. Bandade fixes don't cut it with me. Nlm”

“Consumer advised that the lower intake manifold gasket continously leaks. Had current gasket replaced at 59k miles and gasket is now leaking. The dealer advised problem may be due to gasket's current torque specification, but can not torque any tighter or will break manifold. Ts”
