My 2018 e6 shut down on the road while driving. We first noticed that the throttle pedal wasn’t working and then noticed that the dash display went out. After turning the key switch off and on again, the car has worked as normal with no recurring issues. Just before the car shut down, we were about to turn right and had activated the turn signal.
We checked all fuses, relays, and obvious wiring issues but haven’t found a problem. The traction batteries and 12v battery was fully charged. Has anyone run into issues like this? What was the cause/solution?
