While driving the car and at a stop light the car made some jerky noise and got the "drivetrain malfunction - stop and turn off engine. do not continue driving. call roadside assistance" message. this has happened about 6 months ago and had the car towed to the service and they never found any problem. now in the span of a day it has happened 3 times. when i turn off engine, wait a minute or so and start again, i was able to drive the car again. i am not sure why this is happening and i have looked through all bmw forums and facebook pages and nobody seems to have an answer. i am worried about driving the car and having it completely halt in the middle of driving on the freeway. this needs to be addressed by bmw and i have yet to get an answer.
Charged my car overnight in my climate controlled garage and went out the next morning to run errands. turned it on, put it in drive, heard a pop or clunk from the rear and then got a drive train not available - do not move vehicle error. couldn't even put the car in neutral for towing - bmw roadside had to send a tow truck with skates to prop up the back end and push it out of my garage. it's been at the dealer almost 2 weeks now - the local mechanics have had calls with bmw back in germany and they can't seem to figure out what the problem is.
