Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“Both front inner brakes not properly contacting rotor. Only a 1 inch width of inner brake pads have ever contacted rotor. Based upon the amount of rust and pitting of the non contact area of the rotors it appears that the brake pads were never contacting properly. In all my years of servicing vehicles I have never seen this type of defect before.”

NHTSA complaint #10227879, filed 2008-05, 300,200 miles“Vehicle would not stop when foot brake was applied. When brake was applied vehicle lunged forward. Driving on a main road, passing through a school zone and approaching a stop light. This was the second time vehicle would not stop in the past two months. I hit the rear of another vehicle damage occured.”
NHTSA complaint #10957971, filed 2017-03, 130,000 miles“Dt: when applying brake pedal pressure the pedal goes past the accelerator to the floor, most often this occurs when starting the vehicle and placing it in gear. When this occurs it is easy to hit the gas pedal as well when trying to apply brake pressure. This causes the tires to squeal and the car to lunge forward. Has been to a dealer who said he would have a service manager call the consumer about this problem, but he never returned the call. The service representative noted there was nothing wrong. No repairs or changes have been made.”
NHTSA complaint #10129725, filed 2005-07, 200 miles“I had a flat tire well my insurance company sent someone to come and fix it when they got here my car was shut off and in park position, he asked me to press on the parking brake which I did I got out of car shut the door he jacked the car up and the parking brake didn’t hold and the car came down almost on his. I had to get cylinder blocks and put them under the tires while he jacked up the car to fix my flat. Very dangerous”
