Greetings forummers Need some advise from this forum group .. decided to get 520d as I was reading thread about 520d and test drove the car .. love it and got the car last week .. here's what happen - 3 days after I got the car .. while at the traffic light .. suddenly a warning comes out at the console stating that the Driving Stability failure .. my car stalled .. then I called the sales guy and he asked me to stop the engine and restarts the car .. did that and everthing is Ok .. 4 days later .. it happen again .. but this time .. the wiper and the signal indicator came out as well .. called BMW and asked to do the same (turn off the engine and restart) .. they asked me to send the car for them to check .. went to AB Glenmarie for check up and to top it off the service was appaling .. big time !! they can't even tell me when can they solve the problem and they don;t have any car to ease my traveling problem ..sigh!!My question : 1. Have any of you guys had this problem ? Can it be solved? ( they told me it might be the sensors ) 2. Should I write a formal complaint .. the car is just a week old and only 600km .. upset that this could happen to me ? 3. To whom should I direct my complaint? 4. is it possible to get a replacement car?Still upset about the car actually .. anyways thanks in advance for the advise given .. having said all those things .. I have no regret gettong the 520d .. love the car .. but maybe not the one that AB allocate for me !!!!!
