Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“I own a Scion xa, my dealer insists there is nothing wrong. The car lunges and suddenly accelerates and sometimes, it is hard to get it to slow back down the tachometer lunges past 4. I do not have floor mats. The dealer insists it is me not the car. This car accelerates suddenly and it has happened several times. Something is definitely wrong with this car. One time I couldn't control the speed at all nor would the brakes work. I am not making this up.”
NHTSA complaint #10348573, filed 2010-08, 85,000 miles“In may 2007 I had a rear end accident with another car where my car would not stop when I put on the brake. The other car moved forward and my car still would not stop and hit it again. It finally stopped when I put it in park. It seemed to me the accelerator was overpowering the brake. It happened on two other occasions. I have taken it to the toyota dealership twice for it to investigated, once after the accident and again last year. They could not duplicate it and told me the car uses drive by wire technology and it was impossible for what I am experiencing to be occurring. …”
NHTSA complaint #10315877, filed 2010-03, 1,000 miles“While driving down the highway on the way to work the car suddenly went into idle. The car would not accelerate making it difficult to get it out of the way, luckily I was on the road in the early morning when traffic was sparse. Upon consulting my local toyota dealer they stated it is the throttle body which is common in this motor. I have found that I am not the only person to have this issue and really think it should be investigated as this is an extreme safety issue and a recall should be issued.”
