I'm new to the forum and have had my M3 for 6 weeks. Yesterday my vehicle had a compete meltdown on the motorway and was towed away. Regen braking, steering assist, traction control, stability control and air bag all failed. It was a seriously unpleasant experience and felt like driving a tank with limited control. I'm currently without a vehicle and have been offered a diesel Mercedes as replacement which I declined. Getting a temporary electric vehicle replacement is solely reliant on Enterprise having stock. I have no idea when I'll get my vehicle back as the Edinburgh service centre is closed and my vehicle is currently housed at the recovery company's premises. Has anybody else experienced such a catastrophic failure? If so, what might I expect going forward with regards to repair?
