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!!!

At least up to 5 issues with the back up and front camera systems, and an issue with the navigation system. The camera systems are especially troubling since the go out at random. The last time the dealer replaced the entire camera module system and the issue came up again.
