Example complaints

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

“I am having problems with my braking system. I had my brakes fixed in february 2001, it is now 10/2001 and I have had the brakes replaced again. I am a safe driver and do not drive dangerously or wreckless. I do not understand how wear and tear occured so quickly. My front end vibrates vigorously while breaking. Stopping several feet past the point where I breaked. The brake pedal went all the way to the floor. I have to stop way ahead of a stop. Also, my car shakes and the brake pedal vibrates when I try to stop. …”

NHTSA complaint #753653, filed 2001-10

“Vehicle would remain in lower gears while in normal operation, running rpms up higher than it should have been. Consumer took vehicle to a dealership, who replaced transmission from another vehicle. Vehicle operated normally until september 2000, when transmission would rev up to excessive rpms at speed being traveled. Please provide any additional information/attachments.”
