While attempting to accelerate from a stop light, the Prius stalled. It would not accelerate although the engine revved. I restarted the car by powering completely off and back on. I tried to accelerate again multiple times until it slowly came up to speed the third attempt. The car was in drive and has never happened before. This is a safety concern for multiple reasons but the main being it can cause harm to those in the vehicle as well as other drivers on the road when the car stalls unexpectedly. There were no warning signals on the dash. Toyota dealer looked at it right away, ran diagnostics, and could not find an issue. Nothing was -??fixed-?? or updated.

Anytime I change elevations the engine seems to rev when it is idling on cruise control. On the downhill, the car will accellerate to ignore the speed on cruisecontrol to dangerous high velocity. I reported this to Toyota of North hollywood three times... it was never addressed.

While accelerating from a stop, and turning onto a highway to merge into moving traffic, the engine briefly stalled for a few seconds after I had already entered the traffic lane and was attempting to accelerate to traffic speed..
