Loss of power steering on startup or at stop light. A message pops up indicating that the Dynamic Stability Control is re-initializing and that steering may become difficult: Drive carefully. The warning message usually appears shortly after the failure. In fact, the steering gets so stiff, that my wife can barely turn corners. The problem comes and goes unexpectedly. This is my wife’s car, and it has happened to her on several other occasions. Sometimes we can reset by restarting the car, but that isn’t reliable. We put the car out of ECO mode into Sport mode, so that the engine does not stop at stop lights, but the engine sometimes stops anyway. When it happened at a stop light today, we tried several restarts, but the steering remained out. Steering is worse at low speeds. Today, we stopped at a light. My wife was driving. The engine stopped and restarted, and the error message appeared. She had difficulty steering into a parking lot where I swapped places with her. I drove her home. It was difficult for me to steer around corners after today’s lock up, but I drove the car to a local BMW-Mini mechanic with whom I had discussed the problem, but it never appeared at his shop. Today, we tried starting at the shop and the difficult steering persisted without an error message. He ran a quick scan indicating that some modules in the steering column were not operating properly. He said the modules were not available for replacement, and that the entire steering column might need to be replaced. Unfortunately, he was booked up until Friday. I drove home and let the car sit in the garage for a couple of hours. I started it while writing this to try to more accurately reproduce the warning messages. However, no messages appeared and the car steered easily. Clearly, sudden loss of power steering poses a danger for my family and others on the road. I’ve looked on the internet and discovered that others have experienced similar problems with steering in Mini Coopers.
