Last week I turned in my brand new (less than 800 miles) 2017 BMW i3 REx in for service after the check engine light had come on at unexpected times (while not on REx). Through ConnectedDrive I noticed a 70+ mile drive occurred while the car is still at the BMW service center (it's been there for close to 5 days).
I am wondering if this type of diagnostics is to be expected, and if a service center is allowed to add that many miles to a brand new car without notifying the customer?
