Eversense I cleaned off battery acid of my used rental 2012 Dodge Grand Caravan SXT, the radio and window switches would not shut off when I removed the key from the ignition. I had and after-market Pioneer Double-din installed to replace the OEM AM/FM sing CD deck and I still have this problem. I was told this was due Dodge's CAN-bus system. I don't know if this is related but, out of complete randomness the battery light would come on. During this period we would experience no issue while driving, the light would go away when we would put the van to sleep and restart. Any comments are well welcomed, thank you
