Engine Shut Off
 

Last night I was braking, somewhat hard because it appeared sooner than I thought but by no means full braking, to make a turn on to a side street when the engine just shut off. It was extremely difficult to make the turn once I lost power steering and almost ran over the curb. I was able to put the car in neutral and restart the engine. It has run fine since then but has anyone else experienced such a thing. I already had an visit scheduled at the stealer to get the routine maint done and attempt to update this horrid transmission software. The X3 is my wife's ride but of course after that she has even more of a reason to take my new 5 with comfort seats away from me....... ah the joys of german software....

Can you give more details about your X3? Year, engine, transmisstion, etc.

I guess that would help........... 07 3.0si auto.... 16K miles..... it's either a 9/06 or 10/06 build

It could be transmission-related if the engine just stalled.

i had the exact same problem, hard braking doing a right hand turn into shell for gas and the engine shut off on me, mine is either a 3/07 or 4/07 build date. happened right around the thousand mile marker, at 4.5k now, hasn't happened again, but it was quite scary.
