What owners report
Short excerpts of NHTSA complaints in the original wording. These are owner statements not verified by NHTSA; personal data removed.
Driving the car at 45 miles an hour, heard a buzzing noise getting louder and louder, the accelerator was picking up speed on its own, pressed the brakes and the car wasn't stopping, I was on the highway, took the steering wheel made a hard left, was in the left lane, hit the concrete divider to avoid hitting other…
Brakes failed to stop self-propelled car. Manufacturer not acknowledging car problem. Putting burden of proof on me. I have no witnesses . I reported this to you on 5/28/00 and do not see it appearing on your website. I called this a.m. Got no where with your operator. I have copy of voq confirmation.
I heard a loud bang and felt the vehicle shudder violently. I immediately pulled over and inspected the vehicle. I thought that perhaps the entire exhaust system had fallen off the car but it had not.
Without any memory of hitting any bad potholes or anything else that could have compromised the suspension. While sitting in line to pick up the children at school the top support on the coil spring gave away, releasing the spring and causing the front of the car to strike the ground.
Brake lights are a safety issue or they wouldn't give traffic tickets if they are not working. Since every law enforcement agency in this country recognizes that brake lights are a matter of public safety I am sure that you do also. At least the wiring doesn't melt with the gas tank back there.
Crankshaft pulley harmonic balancer detached from engine while driving, causing loss of power steering. Very dangerous. Car has only 14600 miles.
The light in the dash board that comes on when brake pads are low did not come on until pads and rotors were below specs, and I had to replace the rotors. The warning system to replace pads did not perfrom it's job because the rotors were worn to the point where they had to be replaced.
Brakes are worn out, and t rotors are below safety level.
