Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“While driving straight on interstate I-95 during rush hour at approximately 30 miles/hour, I pressed on the brakes and the pedal dropped down and started making a weird noise (like grinding sound) and the car wouldn't stop. The ABS light turned on, check engine light turned on, the pedal lost pressure and the brakes locked up. I ended up in a crash, rear-ending the vehicle in front of me. The car has now been repaired from damages from crash but mechanic found no problem with brake system. …”
