Electronics Module Issues?

First the radio stopped working, no

problem found but then it started working again. Then the ac was registering low Freon, but there was no leak. Then the backup camera stopped working, but started again. Now the door locks work sporadically. My dealership is stumped. Help?!

Any history or things to mention about the condition of the car?

 

What is the condition of the battery? I have some friends who had some VERY WEIRD symptoms and they have found out that the battery needs to be replaced (or loosed terminals needs to be tightened up), and for sure with the same exact rating (80 Amps in their case)

I agree sounds like the system is dropping below minimum voltage, low voltage with cause damage so most new equipment shuts itself off to protect itself when voltage drops. Check battery and alternator.

I think there was an issue with one of the battery cables on some of the models. I agree with the other posters, batteries can cause some very strange things to happen and sometimes it is either a dead cell or a cell on the way out and can be very hard to diagnose. Good luck.

Thank you all! We’ll try a new battery. It is the original battery and I have been driving it since 2014 with 60k miles on it now.
