The whole system of the car shut down. My hydraulic unit failed and they will not cover it under warranty. Thank god I wasn't driving when this happened.”
NHTSA complaint #11149748, filed 2018-11, 90,132 miles“Yesterday the car drove fine untill about an hour before I went home. Then it started with the bumping/jerking when switching from electric to gas. Worse than it has ever been. Then the revving started, more than usual, and wouldn't accelerate. Then it was like the throttle stuck. Got the revving noice, but the eco wasn't burried at red, for about 1/4 mile before I was able to pull over into a parking lot. Shut off the car. Restarted and drove 1 mile to home. Revved a few times in that period.”
NHTSA complaint #11171828, filed 2019-01, 151,000 miles“After the 6th or 7th time the car is started, there is no radio sound. I have to turn the car off then back on 5 or 6 times to get the radio to engage. This happens regularly, starting a few months after I bought the car, which was brand new.”
NHTSA complaint #10789647, filed 2015-11, 5,000 miles“After I exited the freeway while traveling to my mothers on thanksgiving day I was stopped at a light to turn left onto a street and when I tried to go the car would not move I had to push the gas peddle all the way down and when it finally went it jumped/jerked really bad which almost caused me to hit the car in front of me and after that it was going really slow. 2 days prior the car was lagging while slowing down to break seemed like the system wasn't reading that I want to slow down and stop which again almost caused me to have an accident. …”
