2010 Toyota Prius - when braking, if you hit a bump or pot hole in the road, the car lunges forward (accelerates). You have to really pay attention for this occurrence or you will rear end someone. I has happen about 5 times now. This seems to be a electronics issue not a pedal problem.

We recently purchased Prius 2010 V with technology option. After driving it for two weeks car design has caused a life-treating situation for driver and two passengers (one of them being a child) by stopping at the intersection in a non-drivable condition in a way of high traffic in the night. Car had to be blocked out by police for 1.5 hours and later towed to dealership. Later investigation revealed that inability to drive was caused by instrumental panel light dimmer turning off instrumental panel when headlights are switched on. Note that dimmer itself was not operated by the driver (it might have been moved unintentionally some times earlier) and actual act of turning instrumental panel off was triggered by turning on headlights which increased dimming level to "full off" state. This car does not have any "non-electronic" instrumental panel and so is not drivable with it off. In fact both driver and passenger was not aware that car is even on at that time because there is no "drive" shift indicator except on instrument panel, and first reaction was to try and restart the car, which further make drive shift position uncertain. This is extremely unsafe design. Dimmer should not be able to make care not operable. In this car without any non-electronic instrumental panel, it should be never possible to completely turn it off. This function should be eliminated to prevent an eventually fatal accident that is waiting to happen (or maybe already happened). Note that car manual does not mention: 1) that instrumental panel can be completely off with the dimmer 2) that there is a dependency between dimming level and headlights. This issue has been experienced by multiple other users as indicated by these threads: priuschat.com/forums/gen-II-Prius-audio-electronics/11744-blank-instrument-cluster-panel.html priuschat.com/forums/gen-II-Prius-care-maintenance-troubleshooting/9053-when-my-headlights-my-dashboard-dark.html.
