Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“I filled up with gas and was leaving the gas station. I hit the accelerator to pull out and the car didn't go. It idled out into traffic, on the road but it wouldn't go. It took about 3-4 seconds before it would take off. Since then it has happened multiple times. It mostly happens when the engine is at operating temp and you stop for a couple of minutes.”
NHTSA complaint #10626366, filed 2014-08, 59,500 miles“Got up early one morning to go to work, started my car, let it run for 2 minutes and put it in reverse and it moved without me pressing on the gas petal and I was parked down hill.now my car starts sometimes and sometimes it won't. It doesn't do it all the time, but it still needs to be repaired. I wanted to know were there a recall on my car for these problems.I haven't took it to a shop to be checked yet, spend enough money on car payments to have to fix my own car and it's under warranty”
NHTSA complaint #10747222, filed 2015-08, 39,240 miles“My problem is similar to another post on this website. My car would rev high on the rpms when starting it while in park and I would have to put my toe under the gas pedal to stop it and it would have to be repeated if it was still doing it while the car was moving, otherwise the car feels like it is pushing forward. I noticed this happed more often the next day if the car was parked quickly earlier, (but not always) and also happened more with less miles on the car when I first got the one owner used car at a toyota dealership with less than 12000 miles. …”
NHTSA complaint #10872511, filed 2016-06, 52,000 miles“My 2012 Kia RIO began to accelerate on its own without my foot on the gas to 60mph on a city street. I almost got into an accident. When the tow truck showed up to take my car to dealership, we started the car and the problem subsided. The tow truck driver told me that he would have to charge me for the tow since the problem isn't currently taking place, and Kia said I would get the bill for inspection since the problem isn't able to be replicated. I have had serious problems with this car for the past 5 months with it sporadically not starting, then starting. …”
NHTSA complaint #10662263, filed 2014-12, 66,500 miles“Car accelerated on its own, RPM's revving while driving down a major highway. Could not get car to slow down so had to steer car into a concrete barrier. Problem existed before the accident doing the same thing(RPM's revving) in park or reverse or accelerating on its own without pushing the gas pedal. Took in for repair and 4 days later was in the accident. Kia dealership telling me that the problem cannot be duplicated while driving it or performing inspection. According to their results, car is safe to drive. The acceleration problem occurred randomly before the accident. …”
