Your car has Automobilus Tourrettus Syndrome. Other symptoms your car may exhibit on it's own are attempting burnouts at red lights near RWD convertables and flashing high beams at oncoming Hummers. There's not much you can do except manage the situation. Psycho-behavioral treatment, education and reassurance for your automobile may be your best bet. Reassure your car that it is a Jeep and has much to be proud of. Take it in the mud once a week, drive over a rock here or there, etc. Medication may be available to help minimize the symptoms. Synthetic oil changes, intermittent high octane fill-ups and regular fluid changes in the diff's.
....all joking aside, I hope you get it fixed soon. This could be quite an annoying problem to have, albeit humorous.
