Regardless of OTA vs dealership-only updates, software bugs can have problematic effects long after the update occurred. So far I've had to take my Chevy Bolt to the dealership twice due to major software problems causing the "service needed" indicator to be lit (equivalent to "check engine"), and I've owned it for barely over a year. The first time, some random bug made the car think there was something wrong with the transmission under some extremely specific set of circumstances, and as a safety precaution it would refuse to shift into drive if not serviced within 100 key cycles. The second time, it was a bug with the software that manages battery health making the car think the battery had a severe problem. In that situation, as a safety precaution, the car refuses to charge above 40%, disables regenerative breaking, limits the HVAC usage, and slightly limits max acceleration. This is getting very irritating. I bought an EV because I thought it would require fewer maintenance visits to the dealer!
