“Driving on a major road at about 45 MPH the engine suddenly made a loud noise and the car stopped. Unable to put the car in any gear- the engine was still on but would not drive or reverse. Had it towed to service station, diagnosed as an inverter failure minimum 7,000 cost to repair. Fortunately I was able to pull over to the roadside without being hurt. The car is only 6 years old and I was told it was not worth repairing.”
NHTSA complaint #10511211, filed 2013-05, 178,000 miles“While decelerating to turn into our drive way the vehicle rapidly accelerated. We were able to get it stopped by using the brakes, ending up in the yard/sidewalk. There were approximately 10 feet of skid marks. The engine was racing while the brakes were being applied. The floor mat was not involved. The increased engine RPM was not initiated nor controllable by the operator. This was truly an uncontrolled run away that could have been life threatening.”
NHTSA complaint #10598449, filed 2014-06, 119,167 miles“We were driving on the nj turnpike. Suddenly, the car stalled and the steering locked. Luckily, we just started the hour long drive and were on the slow lane and was able to glide the car over safely to the shoulder. The check csv and check hybrid system lights came on and the hybrid battery showed no energy. The car would not start and was towed to the closest Toyota dealership. There were no prior warnings about battery errors or problems before completely stalling. …”
NHTSA complaint #10515984, filed 2013-06, 105,000 miles“My son was driving and the vehicle stopped on him in the middle of the road with no warning or power steering. Vehicle had to be towed to the dealership. Was informed by the dealership that the hybrid generator had shorted and needed $7,300.00 worth of repairs. I am very concerned that this vehicle is dangerous, if he was on a very busy road and this vehicle were to have stopped on him as suddenly as it did that day he could of possibly been rear-ended and seriously injured. …”
NHTSA complaint #10485149, filed 2012-11, 123,000 miles“I was driving my 2006 Toyota higlander hybrid on I 95 in 4 lanes of dense traffic all going at least 60-70mph, when I noticed that I was losing power and my car was starting to slow down. I glanced at the dash to see multiple warning signals - check hybrid, check vsc and others. Fortunately, there was a big enough gap on the left for me to pull across the left most lane because I knew if I did not I was going to stall and likely be in a major accident. It was a very scary moment. I could not restart my car and had to wait to get towed, ( dc rush hour). …”
