I wonder what happens if you disable the e-SIM (in the US) and then a safety recall appears via software update - do dealers have any way to update control modules besides OTA?
This is a huge unresolved issue with EVs IMO; ICE cars are required to provide emissions-relevant updates over software which can operate using a J2534 passthrough device, which effectively means powertrain modules have to allow (potentially signed) updates over CAN using software that can be obtained by an end user (a lot of people don't know this; for almost any ICE car in the US, you can buy a 3-day or 1-week subscription to the dealership level diagnostic software for a somewhat reasonable fee and use it with a J2534 device).
But for EVs, there's no such rule and as far as I can tell it's entirely a gray area in the US now; the NHTSA require a "remedy" for recalls but nobody seems to have pushed back to determine whether OTA is truly a remedy. The traditional autos all offer dealerships as a backup option, but Tesla and Rivian have several recalls with only OTA remedies already. This seems sketchy.
Can I disable all data collection from my vehicle?
