Drove over a speed hump, and as the front tires hit the level pavement, the car lurched forward. Responded to brakes just fine. Happened again a week later as both front tires simultaneously went over an edge dropoff at a construction area.

Prius 4-cyl

  • 15,956 miles
The car suddenly decelerated from 65 miles an hour to about 5 miles per hour while driving on a highway at night with the shoulder blocked due to road construction. This same problem was present in the 2004 Prius and was apparently the subject of NHTSA investigation. There was a recall issued on November 30, 2010 for 650,000 units of the 2010 Prius. Toyota has not been able to determine the cause of this problem in the earlier models and admits it doesn't know the cause of the problem in the 2011 Prius. This defect presents a great danger, especially when driving in heavy traffic at highway speeds.
