“On two occasions, january 2015 and may 2015 my 435I stopped while I was driving without any warning whatsoever. The first time I was crossing a very busy 3 lane northbound road to get to the left turn lane when without any warning the car just stopped. They was no engine light on dash. I was lucky that I was not hit as I didn't even have the opportunity to brake, to indicate to drivers behind me that I was slowing down. The lights, chassis stabilization and drivetrain malfunction came on the dash. …”
