problem #6

Dec 112011

Wrangler 6-cyl

  • 3,000 miles


Potentially a root cause of the rash of fires in Jeep Wrangler that are sitting parked: Failure of the tipm (totally integrated power module). In Dec 2011, my daughter drove her new (3000 miles) 2011 Jeep Wrangler unlimited to church, parked it, turned off the key, took the key out of the ignition, exited the vehicle and locked the door, and went into the church building - never realizing that motor was actually still running!! (they're very quiet when idling and she was talking to a friend.) about 20 to 30 minutes later, a man came running into church that knows of her vehicle and said "your Jeep is running, there's smoke or steam coming out from under the hood, the door is locked, and I can't get in to turn it off! my daughter checked and she indeed had the ignition key in her hand. She ran out of church and unlocked the door, put the key in the ignition but it would not kill the engine! we had to engage the clutch in a high gear on the manual transmission to kill it. Radiator coolant all over the ground. We found that radiator fluid was just about all boiled out of the engine. The tipm was allowing the engine to continue to run even though the ignition was off and key removed - but the tipm did shut off the electrically operated cooling fan in front of the radiator. There was electrical power going to the motor ignition so that the motor continued to run - but w/O a fan. The coolant boiled out of the engine and had our friend not intervened our motor definitely would have boiled itself dry and continued to run until it either seized up due to excessive heat and/or ignited a fire due to the excessive heat (potentially by igniting the fuel within the fuel system"? electrical wire insulation causing an electrical fire?? battery boiling and fire?"). as you're aware, there are several potential secondary sources for fire ignition under the vehicle hood.

My Jeep has been in for the 3rd time this month for the same thing. Leaking transmission fluid on the garage floor. The 1st time dealer found the leak between transmission adaptor housing and transfer case input, replaced trans. Rear adaptor seal and transfer case input shaft seal. The 2nd time dealer verified leak and replaced the same as previous. Now the 3rd time it is in for the same thing. Still waiting to get my vehicle back and it has been 5 days. Dealer called and it wont be til at least Monday til its ready.

1.top intermittently leaks on/near the passenger door, and when there is snow the top acts like a sponge and saturates leaking water everywhere inside the Jeep. I have driven and been in soft tops most of my life and I have never seen a soft top saturate that badly that it soaks the inside of the Jeep. Originally the top leaked terrible anytime it rained along the top of the windshield and passenger side, 4 times I called to complain 3 times they told me it was my fault for putting the top on wrong in winter the 4th time they acted surprised and said oh btw there is a service bulletin 2.the engine makes a terrible high pitch whistle/siren noise from the engine intermittently. It last anywhere from a few minutes to a few hours. I have this on video 2 times and dan's Jeep has heard it also along with many coworkers friends and family. 3.the steering wheel makes a terrible noise when cold initially and recently is making the noise in lesser severity even when warmed up. The noise is like dragging a nail across a spring. 4.twice now my Jeep has had a serious idle/RPM problem I do not know what to call the problem. Saturday the 22nd of October 2011 I started the Jeep, it idled fine. I popped the hood open with a friend to see if we could hear the squealing noise when I gave it gas. When I gave it gas the Jeep dropped in RPM and acted as if it was going to stall out. Experimenting with the amount of gas no matter how far I pressed the gas pedal it continued to sound like it was dying. Friday the 28th of October after driving for well over an hour the Jeep was making the high pitch squealing/whistle/siren noise. Again and at a stop light I went to give it gas as the light went green and the Jeep dropped in RPM and began to stall out it seemed. About 10 seconds later the Jeep started acting normal and accelerated.

At approximately 3,000 miles I performed the first oil change. I found the drain plug, which is typically tight, to be loose. I was able to remove it with my fingers. At approximately 6,000 miles, I began to hear a clunking noise at low speeds. After trying to diagnose the issue for over a week, I finally discovered the problem. The upper anti-sway bar fasteners on the front suspension were loose. I torqued them back to specs myself. I am concerned about what other nuts or bolts may be loose on this vehicle. Jeep issued a recall for "loose suspension fasteners" for 2010 and 2011 models, but my VIN is not included. I believe the problem may be more widespread than Jeep has spoken it to be.

Received a recall letter L35 emissions. Called to get the repairs and was told I would need to ship the Jeep to another island as Chrysler has no repair service on molokai. The companies should have to make arrangements with a repair service on this island. Would cost over $500 to ship to oahu as they suggested.

I have a 2007 Jeep compass and today my husband notice a little bit of rattling in the front end. When we rev up the engine it fades the rattling out. Haven't had the chance to take it to a mechanic just yet, but reading some of the responses it seems to be a common problem (and possibly costly one) to fix which does not make me happy. Vehicle currently has about 83,000 miles on it.
