Is there a fix? Manufacturer service bulletins
The manufacturer has issued service bulletins covering powertrain on this vehicle — documented repair instructions, service campaigns, or warranty extensions sent to dealers. A TSB isn't a recall (it's not a free safety remedy), but it's the manufacturer acknowledging the issue and how to fix it.
The vehicle will no longer move when put into gear. There may also be loud noise coming from the HEAT*(electric drivetrain)/Rear axles. *German acronym for Highly integrated electric drivetrain topology- Hochintegrierte Elektrifizierte Antriebs-Topologie

It still had the malfunction. Had the car towed to the BMW dealer. They tested it and came up with 7 codes of malfunction:…
On 9/6/2023 I arrived home at [XXX] around 3:30 pm. I stopped the car and put the car in "Park". Immediately car moved with full force like a rocket and hit the garage wall head on.

I have been using the wallet…
