The symptom: The car misses or shutters under load. The problem started as intermittent but is becoming worse. The dealership has informed me today that the car needs a new transfer case. The vehicle is a just over 6yrs old with 82K miles. This is a major drivetrain failure in my opinion for a car of this age with average miles and continually serviced by the dealership and driven by two old people. Today I read about a recall for a 2014 model 328D that requires replace the constant-velocity joint and inspect the transfer case, replacing it if necessary. I suspect the same faulty part could also be the cause of my now faulty transfer case.

Vehicle stalled on road way while going 50 plus miles an hour. Shutting off completely. Police were called. Could not get car to shift and move. Needed two different tow trucks to get dollies to move car. BMW replaced fuel pump. BMW says warranty on NHTSA for my year make and model does not apply to my vehicle. I am scared for my life. Felt like I was going to get killed as cars honked going 60 miles an hour around me at 830 at night on beach blvd.

Driving on 4 lane road at 40mph when 2104 BMW 335I xdrive vehicle experienced total failure-starting with the navigation screen then the entire dashboard went black and engine shutdown (all in few seconds). There was no shoulder (concrete curb) so vehicle came to stop in the right lane. Headlights were "stuck" on but nothing else worked including the emergency flashers! contacted BMW assist but they were unable to help but sent out police and tow truck. Car would not shift into neutral and was dragged onto a flatbed damaging the vehicle. This was extremely frightening! we could have been injured or killed as cars were bearing down on us then swerving as we could not warn them without emergency flashers. Before someone is injured/killed, this issue needs to be addressed starting with why does this vehicle not "fail-safe""--I.e., where the emergency flashers work and transmission can be shifted into neutral" thank you!!

Was driving in rain, stopped at a red light with start/stop enabled and in standby mode. When signal turned green vehicle struggled to come to life and stalled with message on I-drive saying drivetrain malfunction and after a few attempts to bring the engine back to life was able to drive through the intersection and pull over to the curb after which the engine would still struggle to idle and transmission refused to engage drive mode. Had the vehicle towed to the BMW service center and they said the low pressure fuel pump failed and replaced it and claim the issue is fixed.
