| Description of the problem | The car randomly stalled at traffic lights for about ten times now throughout my 3. 5 years' ownership. I bought my car in march 2010. Within one month, the engine stalled when braking to a full stop at traffic light. The dealer couldn't reproduce the problem. One month later, my car cut off again while sitting at traffic light. Another one or two months later, it happened the third time. The dealer kept my towed car for two weeks but had no clue. From then on, i just gave up. One day, when it sat at traffic light, the car shook a little like someone hit me. The other day, this hit-like shake happened again while at traffic light. This time, the car even shook several times during driving after leaving that traffic light, with the check engine light blinking in accordance with the shake. On the following day, my car finally stalled again at a traffic light. Except the first one, all other occurrences happened while the car sat at traffic light and i stepped on the brake pedal. After i restarted the car, it could run smoothly for at least one month. Given the occurrence frequency, the chance to reproduce the problem at dealership is almost zero. And they refused to lend me their computer that i could hook up to the car to record driving data. I had also contacted hyundai customer affairs. All they can do was just send me to the dealer and close the ticket. Recently, the car stalled again during a low-speed driving. The car lost driving power completely with check engine light on. I was completely shocked and hurriedly stepped the brake, switched the gear to park, and restarted the car. Fortunately, no car was around. This is really terrifying and i am really disappointed and embarrassed. |
