My 2012 Journey worked fine until March of this year (2020) when at that time the battery would go completely dead within 2-3 days of not driving the car. I had the battery replaced at the dealer, and it still kept draining. So I took the car back to the dealer and they tested the drain (cost me $607) and it turned out to be the Bluetooth module which I never used because it was not compatible with the newer iphone. I was told that the module was defective. To replace the module it would have cost me $1279.90 which is absolutely insane. I said disconnect it and leave it like that. So far the car has been working fine since then.
