I purchased 2013 vehicle 3 months ago. I have taken vehicle in for repairs w same error 4xs - error "drivetrain - vehicle can not be restarted" I have been on freeway and on street when error has occurred. Wjen this error occurs vehicles electrical components no longer work. Vehicle can still be driven but with caution. I am very concerned and cannot take long trips away from BMW service locations since this error appears without warning. BMW dealer kept vehicle for more than 7 days last repairs, however I still have error appearing and vehicle is still not repaired. Dealer nonchalant since warranty is still in place -- I believe they are ignoring as not to relate drive transmission. Tomorrow I have no vehicle since car won't start. Contacted dealer to come and deliver rental vehicle. I have to work! error appears when vehicle is in motion always. I am concerned with my safety - not sure what else will take place while vehicle is in motion. Today weather was 112 and no air conditioning for 40 miles. I need vehicle repaired as to pass emissions as well as for my safety!!!
