Example complaints

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

“The ABS activates at low speed braking under dry road conditions without the tires locking up. The brake pedal vibrates as if I were on ice with the tires locked up. Braking effect is reduced under these conditions. This happens randomly and when it does I cannot be sure if I can stop in time before hitting the vehicle or object in front of me.”

NHTSA complaint #10809780, filed 2015-12, 62,000 miles

“Started my vehicle applied the brake to shift to drive and the brake pedal went to the floor. I got out of the vehicle and there was a puddle of brake fluid on the ground on the driver side under where the drivers seat is. There was brake fluid dripping from a rusted brake line. I'm lucky this happened when the vehicle was stopped and not while I needed stop because it was a complete loss of brakes.”
