| Description of the problem | My vehicle has the same incident about a dozen of times in the last 4-5 years. The vehicle suddenly had check engine light, abs light, traction control light, and brake light on, engineer started to knocking, speed forced down to less than 30 mph within in seconds. It was quite scaring when the vehicle was on the highway with speed at ~50-70 mpg. My dealer has made several repairs, changing everything in this speed controlling system multiple times according to the book, including throttle body twice, electric harness three times, and control computer unit once, but the problem recurs. Occasionally, resetting the system and/or restarting the car, and sometimes reconnecting every parts of the system can avoid the problem for a while (from a days to 1-2 years). Although it is unpredictable in when, it would come back. The problem seems to come more often when the weather become more wet. This mimics the behavior of the poor electric connections controlling the tails and turning lights of the same model, which was recalled by bmw a couple of years ago. It seems that the same electric connectors are used in this speed controlling system. Obviously, this problem is more dangerous than the signaling light issue since it is more likely to lead to severe accidents/crashes in the highway; i might be dead or severely injured if i did not responded quickly enough when was in i-95 for example. |
