Battery Cable Problems of Jeep Wrangler

Tl the contact owns a 2008 Jeep Wrangler. The contact stated that on several occasions the doors locked and unlocked independently, with the horn blaring and headlamps flashing with the windshield wipers activated without warning, or driver input. The contact became aware that the failure was due to the failure of the totally integrated power module (tipm). The contact stated that to prevent the failure, the negative battery cable was disconnected while the vehicle was parked. The vehicle was not taken to be diagnosed nor repaired. The manufacturer was not made aware of the failure. The approximate failure mileage was 115,000.

After driving in the rain with no leaks evident the next day the car had the wipers running even when the switch was in "off". The headlights are on even though they are switched "off" and the instrument gauges are all non functional as well as the odometer and dome light. Removing battery cable fixes the issue one time then it goes back to not working.

Dash cluster flickers, Jeep shuts off while driving, sometimes starts threw out stall on its own. Won't start all the time. Have an issue we're my battery cables are massively melted causing smoke.

I opened the door to the Jeep and the wipers, horn and wiper fluid engaged non-stop without a key in the ignition. The only way to stop them was to disconnect the battery. When the battery cables are reconnected, the horn, wipers and wiper fluid sprayer are again engaged. On quick research, it was discovered that this is a known tipm failure issue that can also effect the airbag (preventing deployment as well as randomly engaging it while driving), fuel injection causing sudden loss of power and vehicle control as well as issues with lights and gauges. Issues were severe enough to issue a recall on 2007 year models but similar issues with the 2008 are not addressed. I was fortunate the the vehicle was parked in my garage when the tipm failed and not driving down the highway.

Opened passenger door. Front and rear wipers turned on by themselves on high. 30 seconds later horn went on constant blast. Started vehicle, wiper and horn still on. Pulled keys from ignition, but vehicle stayed running. Popped clutch to shut off. Pulled battery cable. Everything reset. Later in day, tried to start, wipers turned on by themselves again, hazzard lights started flashing - but Jeep would not start. Power locks and windows would not work. Radio did work along with headlights. Starter would not click or engage, it was just dead. Towed to dealership. Tipm replaced twice previously 5 months and 9 months earlier. Now at dealership, battery rehooked up, everything is fine.

Vehicle shifts hard from gear to gear for first 5 minutes or so of driving. Randomly throws 02 or cps codes. Had all parts replaced more than once. Pcm replaced twice. Two mechanics confirmed it was a faulty pcm. Shifting etc, is better when negative battery cable disconnected overnight. After a few cycles, the issues return. Pcms are defective from the factory. My mechanic currently has two 2006 Jeeps with the sam problem. . Read more...

Driving along about 75mph on I-26. All of a sudden all the lights inside flashed and then when dark. Jeep shut down and went dead. Coasted to shoulder. Shut off ignition and remove the key. Inserted key and started Jeep. About 2 hours later, I pulled over at a rest area, shut of the Jeep, and went to use the rest room. When I returned the Jeep would not respond to the fob to unlock the doors, I used the key in the manual lock. Jeep would not start. I disconnected the negative battery cable for about 10 seconds, and re installed. Jeep started and even 2 days later no return of symptoms.

Tipm failure. Horn, wipers, windshield go off while driving, would not stop even with vehicle off. Have to pull battery cable. Would also go off by just opening door, key not in ignition. Auto transmission stopped shifting gears, a/c fan stopped working.

Driving down the road when suddenly the horn started honking,wipers started on their own as well as wiper fluid squirting , radio came on and lights turning on and off. Pulled over and even after the car was turned off and key removed ignition the car remained running with all electrical equipment running off and on. It seems that many other people have had this problem with their Jeep/ Chrysler vehicles. I replaced the battery cables and started the car again, it was fine for about 30 seconds then it all happened again until I removed the battery cables. I removed the battery cables to the car because I'm concerned that the electrical problem may cause a fire under the hood and possibly burn my house down.

Tipm --- the vehicle began having electrical seizures in which the horn, lights, locks, wipers, and washer fluid all began activating at once. I had to pull over after I lost visibility because of the washer fluid covering the windshield. After turning the car off and back on several times over the course of 10 minutes, I finally pulled the battery cable to stop the problem. But as soon as I reconnected it, the problem would start again. I eventually pulled the horn fuse and limped back to my office and the next day took it to the dealer where they diagnosed the problem as a bad totally integrated power module and charged me $863. 87 to replace it.

Was driving with low speed when I heard the car alarm and heavy smoke started to show from under the hood. I had no full coverage on the truck so I had to take chance to open the hood and remove the battery cable before the whole car goes on fire. Was lucky this is didn't happen while I am driving on the freeway. The technition said that the fuse box was caught on fire.

While driving down a 7% grade hill, the brake pedal went to the floor, warning lights on the dash lit up and the engine raced. Followed by ineffective brake modulation, more lights, increased speed, and panic of wife (driver), children in car seats 2), and dogs (3). Wife was able to use emergency brake to slow far enough to shift automatic transmission to 2nd, followed by 1st, pull off to the side of the road and jam it into park. She drove to the bottom of the hill and into a parking area in 4wd low. The vehicle was towed to the dealer where they found nothing concrete to blame. They speculated that a corroded battery cable caused a voltage spike(s) which the computer interpreted as the vehicle being in a skid and the computer took away all driver control of braking. Luckily, they all survived.

My 2008 Jeep Wrangler unlimited began to have starting problems. At first it was very intermittent and I assumed it was due to a worn battery so I replaced the battery with a new one and the problem was resolved for about 4 days. Again, the vehicle would not start without repetitive turning on and off of the ignition until it would finally start. This problem occurred every few days. Finally on the morning of 8-23-2010 the vehicle would not start no matter how many times the key was turned. After about 50 attempts it finally turned over and I drove it directly to my local Jeep dealer to have the problem investigated. That afternoon I received a call telling me that the problem was common amongst 2007 and 2008 Wranglers. The technician said that there is a design defect which causes a poor grounding between the battery and the starter. He said that they had been installing a new grounding strap between the battery and the starter and that it was $177. 00 and not covered by warranty even though it is a known design defect. Upon getting my Jeep back from the shop I looked under the hood to see this $177. 00 grounding cable and it is simply a $10 battery cable attached to the negative post on the battery and run over the top of the engine, down along the firewall, and attached somewhere on the back side of the engine. Really, it is ridiculous that Jeep has a poor design and then charges owners to repair it. From what the dealer technician told me this is not an uncommon problem.

Vehicle was set on cruise at 45mph and suddenly suffered a complete power loss and stalled. No equipment was functional in the vehicle, including gauges, headlights, radio, etc. As the automatic transmission was still in drive, the vehicle decelerated very suddenly until power was restored approximately 3-4 seconds later, at which point the vehicle restarted itself. Power steering and power brakes were also affected during this power loss, and neither was functional. Battery cables do not appear loose and there is no other indication of loose wiring.
