| Description of the problem | Vehicle would expectedly slow down when you accelerate. The loss of power would last between 2 to 7 seconds. I have already taken the car to the dealer since the 15k-mile service. The dealer could not find anything. Nonetheless, the issue is still occurring on a weekly basis. This is a very serious hazard. Affected vehicle could get rear ended as it accelerate from stop lights when it suddenly slows down. What's worse? Imagine your family in the car when you want to make a left turn, you press the gas pedal to accelerate, but it slows down before you can clear the on coming traffic. I hope toyota is listening to this!!! This defect could have very dire results. I have found similar complaints in various forums online. I am certain more people are experiencing this and don't know where to report it. Nhtsa, please request similar complain data from toyota dealers about this very dangerous defect. |
