Hello dear users.

I have a question for you guys, I don't know if you ever experienced such issue before. My car E84 X1 is having a problem after going to BMW (all knowing, perfect, amazing, super good) "authorized" service.

The car just shuts off everytime I go over a speed bump with 15mph or above. After shutting off car keeps rolling, no check light whatsoever, until it stops or I make it stop. After such issue, there are power in the vehicle all the lights are operational. However, I happened notice that when I go over a speed bump with like 10-15 mph, especially at night, the headlights and the radio go off just a split second, like a blink of an eye.

I just need to know the potential reasons why this is happening. I checked, double checked, and rechecked every connection coming from the battery, yet they are all very secure in place.

I just don't know what to do anymore, I mean if I cannot thrust the authorized services...

Thank you for your help.
