UPDATE: The car with the failed iDrive (2013 BMW 335i) on first day of driving brand new, is now at the dealer (there was a delay getting it there due to surgery). Dealer email to me at end of day: "We would like to keep the car overnight to continue to diagnose the concern". I will update you all after resolution. Thank you for your comments, suggestions, and interest in this issue! My disappointment is vast, so I hope their fix is permanent.
