Well, each person has their own level of what's worthwhile and what's not. Depending on how valuable it is to you, it may be worth persisting. GM has apparently established a partnership with Hertz for a national rental program for this recall, so you might try asking for a rental instead of a loaner. Again, the EV Concierge number appears to be the way to work the process, rather than individual dealers.I've tried contacting GM. It's pointless at this time. As you stated above, the lines are overwhelmed and GM is not responding to my attempts to contact them. Neither is the dealer.
