Hi there. I know this post is 2 years old, but I was wondering if you ever determined the issue? I currently have a 2012 Dodge Journey RT. About 2 months ago, I had the first, shall I say "event". While driving one night, the wipers came on by themselves, the dash lights went out, my dash warning lights came on, and I had a NO BUS message where my odometer reading would typically be. Went home, put the battery charger on it, (charge after each event, and battery is typically down to about 50% at the time). Took it to a local garage, paid for a diagnostic, which said TIPM was the issue. We have replaced the TIPM and it is doing it again. We are at a loss, and cannot afford to keep taking it for "diagnostics", only to find out that the answer did not fix the issue. Thank you!
