Hi all. My 2006 Overland occasionally resets its on-board computer while parked, or on one occasion while on the move. Also the alarm goes off while parked from time to time - sometimes a 'chirp' and others a full sounding. My initial thought was 'loose battery connection leading to voltage drop, thus setting off the alarm'. This isn't the case, so I don't know what to look at next. Has anyone else suffered this please? If so, what fixed it? Thank you.
