| Description of the problem | As i am riding along at a steady rate, all of a sudden the car will slow down. Sometimes it slows 5-10 mph and starts to accelerate. At other times, it will slow to a complete stop. Before going on vacation, i took it to pantili hyundai in princeton, wv and they did a computer update and told me it was fine. I drove to memphis, tennessee and it started doing it again. On my way home, we stopped in chattanooga for lunch. When crossing a busy intersection, it nearly stopped. A gas truck was approaching as we barely made it across to our side of the highway. Fortunately, there was shoulder room to move to until it decided to go again. |
