I am having serious problems with my 2018 3.6l. First two days ago I got a “service stop start” message on the dash. Then my auto park would randomly engage.
I tested both batteries yesterday and they are reading 12.5 volts off and 13-14 running. I disconnected both batteries from each other and left them disconnected over night to see if anything would change. This AM they both read 12.5. When I started the Jeep the 8.4 system controls looked different and radio wasn’t working right (Xm radio didn’t show up).So I shut it off and restarted it and everything worked fine except all presets were gone.
After work I took the Jeep to get both batteries load tested. Both tested fine but the guy at the auto parts store said that the aux battery read as only being 75% charged but it load tested fine. I reconnected everything and drove home only to find the reverse camera now won’t come on, in fact there isn’t even a button on the 8.4 for it anymore. The off-road pages ap is gone. Xm isn’t there. Heated seat buttons are gone. Even weirder the AC only reads MAX and LOW and no settings in between.
I am at a total loss. I tried a hard reset with fuse F11 and nothing changed. I tried disconnecting the batteries for awhile and when I reconnected the same scenario as above. It’s like it gets worse and worse by the day.
FYI it’s out of warranty and I don’t really wanna start buying parts without a game plan. I have checked to see if all fuses are pushed down and looked at grounds. Is the little battery causing all of this? HELP!
