The electrical connection between the starter-generator and battery may come loose.
Complaints are unverified owner reports to NHTSA and are not normalized for sales volume. One complaint can cite several components.
“While driving at highway speed on [XXX] I went to put my windows up. Without touching anything else my seat moved backward and I was unable to reach either pedal. Fortunately I was able to maneuver to a point where I was able to regain vehicle control. Obviously this was a life threatening situation which could have been disastrous. There was no auto correction by the vehicle. This was reported to BMW of Barrington , IL and serviced on XXX. No specific explanation has been provided. This is just one of many issues with this vehicle that appear to be related, and escalating in severity. I can't determine how they are related, if at all. I don't trust the safety of this vehicle and am not convinced BMW to date has performed a complete root cause analyses from the date the vehicle was put in service. I have requested BMW replace this vehicle.”
“This is the third Check Engine, Drive train malfunction, Power Supply error messages popped up. Dealership replaced the battery at the first visit, replaced the starter at the second visit. Error messages appeared one week after the second visit to the dealership.”
“1 week after the BMW dealer replaced the battery under the warranty (after the car was towed due to the power loss from drive train malfunction) Engine Check, Drive train malfunction, and Oil level measurement inactive signals popped up again.”
Towing, payload and dimensions aren’t in the EPA or NHTSA data, so we don’t list them.
