I couldn't find a reference to it in this forum, so I thought I'd share. Apparently, the rear turn signals do not give any cue when one burns out. For example, in other cars, I've been tipped off to a dead bulb by seeing the signal flash rapidly. The remedy is to have the dealer install a software update that modifies the Car Configuration File (CCF), which should not take very long. I guess I'll head to the dealer before the car takes a turn for the worse.

I have to say that I'm pleasantly surprised that the car (a 2022 model) has had as few problems as it has, given the relative newness of the technology. We made it safely through the battery software update and had a recall because the car wasn't loud enough. Other than that, there are times when lane-keeping is not available.

 

The taillights in 2022 should be LED-based, which should be good for decades. However, you likely have a blown fuse, failed switch, or broken wire.

 

I don't actually have a light out. The recall is to make sure I know if one does go out.

 

I'm sorry I misunderstood. Still, with LED taillights, this shouldn't be the issue it would be with bulbs. Ironically, if you convert an older car to LEDs often that'll trigger a bulb out alert because they pull so much less power. Best of luck with the other stuff!
