I first reported this to toyota prior to the initial 2010 recall, the car was less than 1 month old and i have reported it on numerous occasions via the toyota website. On the few occasions i lent the car to friends they have had the same experience. Description: when traveling at relatively slow speeds and an unexpected bump comes up and the brakes are engaged early, once going over the bump the car losses brake…

I have a 2010 prius. Occasionally when i go over a bump (pothole, train track, rough road) my car feels like it jolts forward for a few seconds. This happens when i am not hitting the brakes so i don't think it is covered by the anti-lock braking recall. It is difficult to replicate this and i haven't reported it to the dealer because of this, but it happens about 1-2/week. It could be a problem in a traffic…

When the road surface is slippery and/or uneven (i.e, pothole is beginning to form), my 2010 toyota prius has "surged" or accelerated suddenly at low speeds under 30 mph, for no apparent reason other than coming into contact with the bumpy/slick road surface. This sudden acceleration responds to braking and has occurred approximately 5-8 times, with more frequency since the rainy weather began. This is frightening…

1. I was driving in san francisco, ca on city roads. In both events, i was braking to minimize the impact of driving over potholes or uneven pavement (holes that were recently filled with asphalt) seen ahead. 2. When the brakes were applied, there was a brief, momentary surge in power followed by normal braking. On one occasion, a passenger riding in the front passenger seat also noticed the surge and commented on…

I have a 2010 prius which i bought in august 2009. On several occasions, approximately 8-10 times, i have been braking at slower speeds when coming to an intersection. When i put my foot on the brake and the car happens to hit a bump or hole in the road and the car noticeably surges. My foot is not on the accelerator and this has nothing to do with the floor mats because my floor mat is pinned to the floor of the…

I have experienced a sudden acceleration type problem when driving over rough pavement and potholes, etc. The acceleration is for a split second and i suspect it may be related to the lack of traction from the tires. It does not appear to have anything to do with loose floor mats or a sticking pedal. No repairs have been made. Dealer said they never heard of the problem when i went in last week. I was offered to…

2010 prius, less than 5000 miles. On the i-5 (ca) going to san francisco on 12-24-09. On a slight/moderate downgrade with cruise set at 70 mph, the car was braking hard and was over 100 mph before i realized what the noise was - and immediately took it out of cruise and braked. It came under control. On or about 12-31-09 i was unable to engage cruise on the freeway but the following day it engaged normally. *tw

In my 2010 prius, the vehicle randomly accelerates when the cruise control is disengaged. This happens every 10th or 15th time of disengagement. When the brakes are applied harder the vehicle slows properly. The unexpected acceleration is very dangerous in traffic. The vehicle has been checked by the dealer and i was told that nothing is wrong. I called for a second time and was told the problem is not on the recall…

Nothing stuck and when i applied the brakes the cruise control cut off and the car slowed. I have experienced this one other time and again it was interstate driving with cruise control on. *tr

I have a new toyota prius 2010 and have experienced the loss of braking combined with a simultaneous acceleration about 4 times now. It is incredibly scary.

I now see that others are experiencing the same problem. This has to…

To the nhtsa: i am an owner of a 2010 toyota prius that i purchased in june 2009. Since owning the vehicle, i have had about a half-dozen to a dozen occurrences of the same problem.
