I hope this will help somebody. I have a 2012 Dodge Charger SXT & my Uconnect/Bluetooth quit working about 2 months ago. I researched online to see if there was a way for me to fix it myself. Alot of ppl are having the same problem with Dodge. I tried all the tricks. Nothing worked. The one thing I didn't want to do was to replace it completely like other ppl had to & costing around $700. Meanwhile every now & then the battery saver mode would pop up on my messages/dash which had me worried so I went & had my battery tested. I had it tested for free at Advanced Auto Parts. My battery read good but stated it needed to be charged yet my alternater was good which I knew bc it was replaced by a recall not long ago. I still had the original battery that came with the car. So the man said maybe it's about to go bad & that's why it's not getting/holding a full charge. I mean it is 7 yrs old. So I went today to the Dodge Dearlership near me to get it replaced bc no Auto parts store will install it..believe me I went to multiple different part stores..all bc it's in the trunk & the parts stores won't let them install them bc it's around cables & wires that's a little more complicated they say & puts them at risk of messing stuff up. It states they can't install it on their computers when looking it up for my car also. Anyway my husband read online somewhere when researching my Uconnect problem that if your battery doesn't have full power that some of your electronics will stop working. I knew I needed a battery anyway. My car always cranked & I never needed a jump but just going off the battery saver mode notification & looking up what it meant.. I got worried recently when I saw a video of a man stating don't let your battery completely die in your Charger. Bc nothing will work then. You can't pop the trunk to get to your battery then. He had to climb through the back seats to try to get to the trunk & I don't remember how he got the trunk open but put it this way..you don't wanna have to do it.. After replacing my battery today..my Uconnect/Bluetooth is back working. Dealerships or Service writers aren't gonna tell you if that might be your problem bc everybody's trying to make money. Money to replace a module plus labor vs a battery replacement. Not saying this is always the case but it was my case. So if your battery isn't working as good as it should be then that's probably your problem. Just get your battery tested for free first to see if it's good & charging completely. If it's saying you need to charge it then have them test your alternater for free if it's good then you might need to get a new battery like I did just so everything works like it's supposed to. If that's not your fix then maybe it's the module.
