Five problems related to ignition module have been reported for the 2008 Jeep Wrangler. The most recently reported issues are listed below.
Walked to vehicle, pressed unlock on key fob, all electrical seemed to go off at once. Horn blaring, lights flashing, windshield wipers going, and windshield washer fluid spraying out. Tried pressing all buttons on key fob to shut it off, didn't work. Out key in ignition and turned it. Did nothing. After a couple of minutes it quit on its own. Same thing happened two other times today. Google shows same symptoms with all Jeeps and other Chrysler vehicles 2007 - present. Issue appears to be faulty tipm module. Contacted dealer and Chrysler/Jeep. Same answer from both, no recall. So I pay to get it fixed, and hope the replacement part doesn't reap out.
My 2008 Jeep Wrangler unlimited has begun exhibiting very strange behavior: 1) the front windshield wiper spray does not work. The rear wiper spray works fine. Very unusual since both front and rear spray uses the same pump. Thus poses a safety issue. 2) the door locks no longer lock when the lock button is pressed on the key fob. This is true for either fob, and yes, I have changed the batteries. 3) the car sometimes does not start. The engine does not crank. This happens at random, and can sometimes be resolved by removing the keys from the ignition, re-inserting them and trying again. Sometimes 5 or more attempts are required to get the car to start. In my research, all of these symptoms point to a faulty tipm module.
Abnormal flashing of instruments panel. Speedometer and gauges turn off while vehicle was in motion, turn signal indicator go off and on. Vehicle temporarily loses engine power. Intermittent loss of electrical power to all dashboard components. Radio, blinkers, wipers go on or off on their own. Vehicle ignition won't start. Diagnosed by dealership tipcm failure; "computer fried" I had to pay for a new wiring harness, had to replace fuse box, brand new sway bar control module along with a brand new tipcm computer bought from dealer. Dealership won't cover repair cost nor is covered by Jeep manufacturer's warranty.
Several issues with the vehicle: 1. "death wobble" vehicle intermittently shakes violently over 45 mph. Stop vehicle and starts running fine. 2. Suspect bad tipm. Intermittent horn and wipers turn on after opening driver door. Next, car sometimes will not start. Tapping the tipm will allow it to start. Next with ignition off and key out, engine continues to run until tapping the module. Finally, now the engine will just stop intermittently while driving down the road. Found that both of these issues are common problems with Jeeps.
Tl-the contact owns a 2008 Jeep Wrangler. The contact stated that when the ignition was turned to the on position, the front windshield wiper turned on, the headlights illuminated, the vehicle would not shift out of the park position and the horn sounded without warning. The vehicle was towed to a dealer where it was diagnosed that the totally integrated power module failed and needed to be replaced. The vehicle was repaired. The manufacturer was made aware of the failure. The failure mileage was approximately 80,000. Djr.
