Constant faults with the touch door opening, the trunk, sign-reading and the front obstacle sensors. The service repaired it under warranty five times — they replaced wiring harnesses, a sensor, uploaded software — and then gave up. They told me they don’t know what else to do. That’s the customer care at a German premium brand. A car worth over 400,000 and they tell the customer they don’t know what to do. I paid the final installment and I’m giving the car back to them. I’m taking a Chinese BYD Seal U DM-i plug-in hybrid with better equipment for 165k after a discount from 225k. With that attitude to customers and those high prices, the Germans will have fewer and fewer people interested in their cars — but they’ve only got themselves to blame!!!
