The car got all the way up to 94 miles per hour before a combination of emergency braking, pushing the brake pedal all the way down and a steep incline allowed Sikes to turn the car off and coast to a stop with the assistance of a California Highway Patrol officer.I pushed the gas pedal to pass a car and it did something kind of funny... it jumped and it just stuck there. As it was going, I was trying the brakes...it wasn't stopping, it wasn't doing anything and it just kept speeding up.
Sikes said he recently took his second-gen Prius to the dealer, but was told it wasn't on the recall list (which is true, although the third-gen is). He told the local news that he's taking his car to the dealer again and won't drive it any more until he gets some answers about what happened. Toyota has sent a field technical specialist to investigate. You can watch a local news report on the incident here. Thanks to Tohe for the tip!
*UPDATE: NHTSA is also investigating.
