What owners report

Short excerpts of NHTSA complaints in the original wording. These are owner statements not verified by NHTSA; personal data removed.

The air bag did not deploy. The car was declared a total loss by the insurance company. I am concerned that the airbag did not deploy with the severity of the crash. I have uploaded three pictures of the car and one of the end of the guardrail that was impacted. The estimate for speed at impact was 35 mph.

While backing up in reverse, the brake did not work. Instead the car accelerated and the engine reved up to what seem to be a very high speed. The car stopped when it smashed into our other car, which was about 4 feet behind it. It was about 5 pm on a dry road. My husband was wearing work boots at the time.
Service brakes · crash · 2012-02-21 · NHTSA complaint #10448861
While driving on the freeway at about 55mph, the car jerked to the side by itself. I attempted to correct the jerk with the wheel, at which point I was unable to do so. It appeared that the wheel was no longer controlling the movement of the car. The car jerked again, I was once again unable to do anything about it.
Steering · crash · 2010-11-11 · NHTSA complaint #10365381
On april 17 2010 I took three photos of a flipped over 2006 hyundai elantra on route 3 in clifton nj. The flipped car looked unusual, and could indicate an unsafe condition. Other cars were involved, but no fatalities. The passengers were able to exit the car. I was not involved in the accident, it was not my car.
Suspension · crash · 2010-04-18 · NHTSA complaint #10326220
I can put on the brakes and get that same thump that I felt when I had the accident and it will take a while for the car to stop. I sometimes pull closer to the curb in case it don't stop so I can hit the curb instead of another car.
