Consumer Description

While driving, the vehicle's RPM's accelerated quickly and then the vehicle stopped in the middle of the road and would not move. I could not even get it to the side of the road to be out of traffic. All regular maintenance has been performed. The mileage is almost 100,000, but not there yet. This could have been a very dangerous situation as I was heading to an interstate highway. No warning lamps ever lit up and no strange sounds or vibrations ever came from the vehicle. This happened suddenly. No warning whatsoever. The vehicle is being repaired today. The transmission is being replaced at a cost of $5500.00.
