Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“We noticed that the carpet was saturated. The dealer told us it was because there were spider webs blocking the drain from the A/C. It was repaired at a cost of $1,554, the work included drying the air bag module and replacement of carpet. We believe this should be the subject of a recall as it is the identical problem recalled for the Toyota camry.”
NHTSA complaint #10551895, filed 2013-11, 63,512 miles“After taking my son to school which is 2.2 miles away, came back home and parked the vehicle on the driveway and noticed smoke from the engine bay. Before the vehicle was shut off, car gave off heater smell and the heater was turned off. My wife came up and got me up, I went down maybe 2 minutes away and found the car fully engulfed in fire. Fire spread to the portion of the garage before it was put of by fire department.”
NHTSA complaint #10660478, filed 2014-11, 93,000 miles“I was driving on the freeway with my cruise control on. It was set to 56 MPH. All of a sudden, the vehicle started lurching. It was like it was trying to accelerate then slow down, then accelerate, then slow down. I immediately shut off the cruise control. It has also happened again today when I tried to use the cruise control.”
NHTSA complaint #10320610, filed 2010-03, 5,800 miles“My 2010 Toyota Prius does not always recognize the key and will not open doors and not start the vehicle. The gear shift jumps out of gear going from reverse to drive and vice versa. The heater does not work properly. I am afraid to drive my newly purchased vehicle. Please advise.”
NHTSA complaint #10310375, filed 2010-02, 150 miles“Exiting from a parking garage. After passing through the pay line, I headed down the exit ramp toward the street. The vehicle refused to accelerate as I pushed on the accelerator. . It did very slowly accelerate to 11 MPH and then started to decelerate. I stopped the car on the ramp, turned the engine off and restarted it. After that, everything was fine, and I was able to drive home. . If this had happened while I was trying to merge into traffic. It would have been hazardous.”
