“My emergency brake has failed. I park on a hil and my car almost went down without me in it , I was getting something out of the back seat when the eb failed, luckily the drivers door was open and I was able to jump in and brake with the normal brakes. Also while braking and going over a bump my brakes fail for a second.”
NHTSA complaint #11076478, filed 2018-03, 100,000 miles“In july, I was braking to a stop on a suburban street but my brakes wouldn't allow me to come to a complete stop in time. It was raining. I finally came to a stop in the middle of the intersection, where I was hit on the drivers side by an oncoming car. Additionally, my side airbag (curtain) didn't deploy. I was traveling less than 15 MPH at the time.”
NHTSA complaint #10911088, filed 2016-10, 83,000 miles“While driving in boston, I attempted to beep the horn to warn a car that was cutting in front of me, but the horn did not work. Toyota diagnosed this as a bad clock spring in the steering wheel. The inability to use the horn is a safety issue. An online search seems to reveal that this is a common problem with multiple Toyota models.”
NHTSA complaint #10914107, filed 2016-10, 99,500 miles“While driving the vehicle the hybrid system failed as per notification on the dashboard. The car was operable but I was not able to drive above 40 miles per hour. I was told by the certified Toyota dealer that the inverter failed and they were not able to provide a reason why it failed. There was a previous recall on the inverter in 2014 to fix a software issue which was repaired. I was told by the dealer this recent incident was unrelated.”
NHTSA complaint #11300773, filed 2020-01, 175,000 miles“I was making a sharp right turn to pull into a parking space, slowing to a stop. The car suddenly and unexpectedly accelerated forward out of my control. I applied the brakes as hard as I could, with no response. As the car was racing into a tree, I shut off the engine by pushing the power button to off. The car knocked down a tree and came to a stop on top of it.”
