There are no messages/warnings. The vehicle will surge at very low speeds such as when I am coming to a stop, trying to avoid a person in a parking lot etc. It was SO scary this evening as I accelerated into a very very busy intersection...I pressed on my brakes harder and it was instant - but about 1 second (which is a LOT in this scenario) later it then slowed instead of accelerated. I have owned the vehicle almost a year. I will be bringing in for inspection this week and let the dealer know. I have put on about 11K in miles and would say this has happened a dozen times thus far with this evening being the scariest one yet. I figured it was just something normal for a hybrid but as I researched online - many people have this issue. TOO SCARY for me and dont want to hurt anyone or myself.

How to use these: a complaint is one owner’s report, filed voluntarily and published unverified. Patterns matter more than any single story. If several owners describe the same failure at similar mileage, put that system at the top of your
pre-purchase inspection list. Back to the
