So many “Drivetrain Error” warnings on REx models which BMW dealers don’t have a clue about. For early adopters brave enough to buy an i3, BMW should fix these errors under warranty irrespective of vehicle age. I have now been badly let down by my REx having a catastrophic failure with my young family onboard including on a trip to hospital. Bad bad image for so-called BMW reliability when they can’t even get a 660cc 2-cylinder petrol engine to be reliable.
