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.

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.

Jeep will start honking horn, wipers on , washer fluid shooting out, door locks won't work. Then it all clears up, there are time when the battery has to be disconnected . But one day while driving to work. All bells and lights went on, wipers on high, horn was stuck on, and then engine just dies! Luckily I had enough speed to get it to the shoulder. Jumped out to pull the horn wire, I was in a residential area at 5 a.m. When all of a sudden engine started back up, with the keys in my pocket! Everything finally stop running and I went on to my job reluctantly. Now sporadically the wipers go on, doors won't unlock, engine won't start, horn blares, washer fluid goes on all by there self. This is my only car to drive, I'm going to an independent dealer to get it hooked up to scan the computer, and hopefully find the problem.

This morning I opened the unlocked front passenger door and the craziness began - doors locked on their own, horn started blaring, headlights tailights and hazards started flashing, front and back windshield wipers started going, windshield washer fluid started shooting out. I attempted to use the remote to unlock the doors - nothing happened. Used the key to manually unlock the door - against the system trying to relock. Then cranked the engine to try and get everything to stop. It did not stop. I turned off the jeep then popped the hood and disconnected the negative terminal. All the craziness stopped. I waited @5 minutes and then reconnected the battery. All the craziness started again. So I pulled the negative and the positive from the terminal hoping to reset the system. I have not reconnected the system to try again. I am worried that even if the craziness doesn't start once I reconnect the battery, if I am driving down the road and it begins it may cause me to wreck. I will send a follow-up email. Thanks.

The first problems to start were the headlights going off and on when the car was off. The inside dome lights also go on and off when the car is not running. 2nd came the battery. It would act like it was dead and the car would not start. This is happening a lot now. If you wait a bit or jump it, it starts right up. Also when in this state all of the other battery operated components work fine, like lights radio, etc. Then came the air bag light and alarm. This will come on for about a minute than go off for a few seconds and then back on. Very annoying. From what I have researched this is the clock spring module or the tipm. I have an appointment wit the dealer this weekend. 11/8/2014.

Tl* the contact owns a 2008 jeep wrangler. The contact stated when the key was inserted into the ignition the vehicle would not start after multiple attempts intermittently. The contact stated that the entire electrical system was fine, however the vehicle would not start. There were not any warning lights illuminated and the problem recurred multiple times. The vehicle was towed to an independent mechanic and the mechanic stated that there was a electrical wiring malfunction that was connected to the ignition. Another mechanic stated that there could be a ignition malfunction, however both mechanics were unable to locate a solution.

My jeep wrangler unlimited x 4 dr would not start and would just click once without turning over the engine. The entire dash was bright and functioning and my battery was brand new. After a few attempts the jeep started as if it was perfectly fine and did not struggle to start neither. Every few weeks to few months it will repeat the same thing over. Also, a few times the dash would show that the jeep was engaged in every gear. I stepped on the brake and shifted the automatic gear from p to 1 and back to p and the dash returned to normal. I have a strong feeling my computer or tipm / fuse box is going haywire yet the dealer finds nothing wrong. I just brought it to the dealer for a diagnostic and he found no errors. Why is there no recall on this if there are so many complaints about the same issues for jeeps from many models and years?? Please help! I have read on many posts that dealers have told customers that there are about 300-400 tipms are on backorder so why no recall? My warranty is still good but I'm afraid the dealer will do everything they can to avoid having to honor it as I was pretty much told they could do nothing for me. I'm still paying off the finance and it's not right that I have a lemon on my hands. The worst part about this is that I am in danger of the engine stalling while driving and now I fear my family's life/safety. No one should have to deal with such a dangerous situation.

The tipm is part of the fuse box. Mine first failed while at a stop light. The symptoms of the failure in my case was horn, washers, door locks, wipers all going at the same time. Afterwards the engine would stall and would not start. The engine would continue to run even after the keys was removed. The code was u0141 - lost communication with front control module. I brought the car into the dealer and they could not find a problem with their diagnostic computer. The module continued to fail and through my own research I determined that it was the tipm. When I returned to the dealer, I had to insist that they replace the tipm. They removed the tipm and cleaned the contacts but it not help. I was told the tipm was back-ordered and had to wait a month while my jeep gathered dust. After a month and a number of calls to the parts department I was told it was further back-ordered for another two weeks. At his point a searched for one on my own. I was surprised to see on the news today the chrysler has still not corrected the backorder issue. The plant that produced the tipm's was in japan and damaged during the earthquake. Caused the parts backorder. I was finally able to locate a module myself by cross-referencing various versions. I am concerned that is the have not fixed this problem I may be stuck without a car again. This is unacceptable. By this time they should have retooled a new plant to provide the backordered units. Since the units are not used in the newer mobile cars, I believe the chrysler is dragging their feet on this at the expense of their older customer base. This is unacceptable. By this time they should have retooled a new plant to provide the backordered units.

I bought a used 2008 4 door jeep wrangler just over 2 months ago. In this time I have noticed every time we fill up with gas, no matter what gas station we use, gas spills everywhere. Also, the battery was completely drained after a month of having the jeep. We had it towed to the dealership where they ran a diagnostic and said it was the battery. We had to pay the for the test and then we replaced the battery ourselves, a couple days later the jeep would not start again! I put the jeep in neutral and it started right up. So now at least once a day I have to put the jeep in neutral to start it. My main concern is that it is eventually going to drain my battery again and I am going to have to keep replacing batteries. I have done research and both of these are "known" and "common" problems, yet when I contacted jeep they act like they have never heard of it and tell me I need to take it to a dealership and pay to have them run more diagnostic tests on it! Nothing has been done about it.

My 2008 jeep wrangler will not start. The starter was replaced and this issue still happens. During searches online I noticed this happens to many folks. During a trip in town and stopping in a bad area my jeep would not start. This is a big issue and I can not and will not travel in certain areas any more. This is not right.

Car will not start successfully due to faulty electrical grounds not present. When car is in park at random times the car will not start. However, if you put the car in neutral gear will start successfully. I have had this problem for 3 years now and have spent money replacing the battery, starter. These repairs did not and will not resolve this problem. Based on my research and other jeep owners the work around is to start the car in neutral when this happens or add ground wires from the battery to the engine block and from the transmission to resolve. This should be a recall from the manufacture and not a out of pocket expense to the owners.
