Example complaints

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

“I was rear ended while stopped, by a vehicle reported to be doing 40 MPH. My vehicle sustained rear bumper damage from the car hitting mine and front bumper / engine compartment damage from the car I subsequently hit. Total damage in excess of $11,000. The air bag did not deploy, but I didn't know if the impact was severe enough to activate it. However, when reviewing the repair invoice, I noticed the air bag sensor was replaced. Apparently it should have activated the system but didn't.”

NHTSA complaint #10632748, filed 2014-09, 24,000 miles

“I was involved in a front end collision with a bobcat front end loader. I struck the implement broadside going 35 MPH. There was no damage to the implement. My car was totaled and the airbag deployed. After going to the hospital and a chest x-ray, ultrasound, and ct scan, it was diagnosed I had fractured my sternum. I am six feet tall and had my seat all the way back. I am questioning whether there have been any other people sustaining a fractured sternum due to an air bag deployment at 35 MPH?”

“I experienced a front end collision in my new 2012 Prius with 2,500 mileage. The collision vehicle speed was nearly 30 MPH. The seat belt did not restrain me and the airbag did not deploy. I was taken to the hospital and sustained a fractured sternum due to hitting the steering wheel and whiplash. There was significant damage to the front end of the vehicle. Toyota's response after their own inspection was our inspection found no evidence of a manufacturing or design defect with the airbag or seat belts.”

NHTSA complaint #10522566, filed 2013-07, 2,500 miles

“My 2012 Prius was hit in back on passenger side at approximately 80-85 miles/hour while my speed was 62 m/h. With impact from hit in the back, my car went flying head on into the median wall (those temporary cement walls used during reconstruction). Two things happened were: 1. After the first impact my Prius had total power loss, not even emergency flasher light would turn on; 2. Non of airbags deployed. I am wondering if all this is normal for this car or there is some sort of malfunction or manufacturing defect?”

NHTSA complaint #10552662, filed 2013-11, 27,000 miles

“While traveling in a rain storm at 17mph, I tried to engage the brakes to prevent from crashing into an 18 wheeler and the brakes did not work. I repeatedly tried to stop the car and the car was accelerating even thought I was applying the brakes not the gas. The car would not shut down, go into park or neutral. I did crash into the 18 wheeler because the engine was accelerating and I wanted to stop.when I crashed the airbags did not deploy. Even after impact the car was still accelerating like it was trying to push the 18 wheeler. …”
