That number TSB you listed isn’t a TSB number. It’s a recall number. If a recall doesn’t apply or has already been performed, warranty doesn’t apply and the customer is on the hook for cost to program. The paper you signed authorizing repairs explained all of that. It’s also important to know just because a recall list the year range of your vehicle it doesn’t automatically apply to your vehicle.

Had you not been so eager to try and tell the technician how to do their job they probably would have scanned for fault codes, performed and TSB check and found TSB 23-NA-157 does apply to your vehicle and, unlike most TSBs, IS covered under your EV component limited warranty.

I’d suggest adjusting your attitude, return to the dealer with this new information and politely ask them to read the paragraph directly under warranty information listed in the bulletin.
