Looks like my dad's X5 is joining the club. There's no good possible reason for user error in this case. He's been driving 60km (40mi) a day, half of it highway, to and from work the last 3 days. He did not leave any lights on by accident. But nonetheless, a flat battery.

This evening when he was about to leave work at 6pm, he tried to start the car and the electronics apparently went on a fritz then the car shut down completely. The key fob was stuck in the slot so I directed him to use the manual metal key to lock the car, go somewhere warm, and grab dinner.

He'd contacted Roadside Assist who cited a 90min wait time; 90min later, they said they didn't have a flat bed available, so the X5 has to stay in the car park overnight until tomorrow, when they will tow it to the dealer. We drove to pick him up at 9:30pm. (Why didn't they tell him the first time my dad called?)

This 7-month X5 really is a dud. Two restraint system faults within a month, creaks and abnormal wind whistle, a loose cruise control stalk, and now this.
