Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“I was gliding into a commercial parking space with my foot off the accelerator in the second before I moved my foot onto the brake. Suddenly, the accelerator pushed down by itself, the car surged forward towards the truck in the space in front of mine. I slammed on the brake. End of incident. No mat was in the way. I had taken part in the recall.”
NHTSA complaint #10436712, filed 2011-11, 23,687 miles“My Prius now has all those dash lights on: !, ABS, vcs. I was driving yesterday, on a city street and the lights came on, and the brakes suddenly did not work-hard to push. For months, when I would drive over rough terrain, I had the loss of braking, accelerating, and the slick road icon would illuminate. The is exactly the same ABS module problem affecting 2010 Prius, ands needs to be recalled and repairs covered.if I didn't stay so far behind other vehicles, I would have rear-ended someone.”
NHTSA complaint #11164066, filed 2018-12, 95,000 miles“2009 Toyota Prius - unintended acceleration. On this vehicle, uncontrolled acceleration can be reproduced at will. I called Toyota and they are treating it as yet another crank call, service manager advised to remove floor mat and bring in later in week. I would hate to see it swept under the carpet like other recent complaints.”
NHTSA complaint #10325389, filed 2010-04, 20,000 miles“I was driving my 2009 Toyota Prius, exiting the staten island expressway and as I approached the intersection the light began to turn yellow and I tried to stop (the road surface was uneven). When I put my foot on the brake the car lurched forward into the intersection so I had to go though the red light and I was lucky that the oncoming traffic hadn't begun to move yet.”
NHTSA complaint #10318355, filed 2010-03, 6,300 miles“I have a 2009 Prius and on at least 4 occasions in cruise control my car has accelerated without my doing so. All of the times I was able to brake and bring down my speed. We tried to report this to Toyota but they were not concerned. We then reported this to the dealership and the mechanic told my husband that that sometimes happens . No report was filed or action taken.”
