Tipm failure. The tipm needed to be replaced because it wasn't operating the engine cooling fan (radiator fan). The cooling fan module also had to be replaced. I understand a failed tipm could cause airbags to deploy inadvertently, window opening failure, random horn alarms, stability control problems, and more. An engine trouble light came on while driving. The dealership explained the power distribution module (part number 68244883aa) and the cooling fan module (part number 68143894ab) had to be replaced because they had failed.

12 jkru 52,000 miles. It first happened at night while wife was driving on interstate Jeep went crazy mode all lights in cluster illuminated warning lights flashing and with hot oil msg, warning dings going off, heard electric fan running. It seemed that nothing was controllable, auto trans went into and would not shift out of first gear. Scared the hell out of my wife. Got home after shut off I tried to restart but nothing happened. I disconnected battery to reset cpu that did not work. I stopped by auto zone to get codes scanned. They told me every system was reporting failure and needs to go to dealer. After restart every thing was normal. After 100 yards down the street it all happened again. Pulled into store parking lot, turned Jeep off and would not restart till 4th try. Drove it strait to dealer in first gear with all. They said that it was tipm and not under warranty, gave MA a rental car for 10 days because part is on back order. After 10 days Chrysler quit paying for rental car and still have no part to fix Jeep it has been 16 days. I guess there are alot of failures for the tipm causing back order and do not know when they will get one.

Air bag light and warning is going on and off when turning the steering wheel. Dealer says the clock spring needs to be replaced. There is a recall on right hand drive vehicles and numerous reports of all clock springs failing.

Yesterday when driving my Jeep to the gas station all of the warning lights started turning on and the Jeep battery light turned on. Knowing that it could be a problem with the alternator I headed home immediately. A block from my house in the middle of an intersection the battery finally died thankfully someone was able to push me out of the intersection because it was dark out and I didn't have any lights. I had the car checked and it is the alternator. I searched online and found that there is a recall for a pentastar 3.6 L V6 alternators but I'm being told that my vehicle is not included in the recall. By specifically excluding my vehicle from the recall they have risked my safety and the safety of those around me.

Faulty tipm.. having trouble with vehicle not starting. The starting issue started in 10/2015 but wasn't a regular issue til 01/2016. Brought to dealership as is is a newer model with only 27000 miles on it. They replaced a sentry module..problem persisted. Now being told it's the tipm. Apparently this is a wide spread issue and was told to report it.. still waiting to see if covered under extended warranty..

2012 Jeep Wrangler have had intermittent trouble for well over a year. Turn car off and headlights stay on. Finally figured out that if I turn the car back on and roll forward a little I can sometimes turn lights off. Same problem turning the headlights on. Rolling the car a few inches usually corrected the headlights. Windshield wipers will start on their own or stop during use with no warning. This began in late 2014 but the problem was so intermittant we could not duplicate it on demand until August 2015. The dealer replaced the multi function switch and wiring harness but before we even drove out of the parking lot both the lights and windshield wipers were doing the same thing. They kept it a few days and "sealed the cluster". didn't have a problem for a few weeks and the car is now 700 miles away at school with daughter. Around Sept 2015 intermittent issues again but not able to duplicate at dealer. Recently (Jan 2016) the problems are daily and include the headlights going out every time the car makes a turn and then come back on a few seconds later. In addition the turn signal cuts off. Windshield wipers have a mind of their own but the lights are the most dangerous problem. Now that the problem is constant it's going back to a dealer but because the car is with daughter away at school it will be a different dealer. We are uncertain about tail lights because this occurs while driving and intermittently but the headlights and turn signal going off while driving through intersections has made this issue a major accident/injury risk.

While driving straight on my residential street my engine stalled and I lost all power to the vehicle. I had no power for lights, flashers, turn signals, interior lights, etc. Basically, the vehicle was totally dead. I was close enough to push the Jeep to my residence and checked the battery and I had full voltage. I had the vehicle towed to the dealership and it was diagnosed as a faulty tipm. Fortunately, I was not on the interstate doing interstate speeds at night...

Vehicle engine light came on after starting engine and driving 30 feet from initial parked location. Vehicle was stopped and explosion occurred under the hood while driver was still in vehicle. No previous indication there was any issue with vehicle. Upon driver emergency exit of vehicle, further explosions and large flames engulfed the vehicle resulting in a total loss of vehicle within minutes.

Faulty clockspring airbag light appears sporadically when vehicle is in motion and I have someone in the passenger seat, notifying me that their airbag is deactivated. Horns volume is weak. Possibly a coincidence, but the low tire pressure alert appears at start-up. All tires (Goodyear LT285/70R17) read 45-50 psi. This part is recalled in 2007 and 2008 Jeep Wrangler, but not for 2009-2016. It is the exact same part.

Basically going 80 mph on the highway my car decides to shut off, endangering the lives of myself and my passengers. Forcing us to stop at the side of the road and call a tow, keep in mind this all happened at 2 am in the middle of a dark empty highway. I take it to the dealer the next day and after running the diagnostics they tell me it is a faulty tipm. Now they are trying to charge me a $1,000 in repairs to replace a part that comes faulty from the factory.

Several problems occurred electronically with my Wrangler in the past 2 months. 1. headlights turned on when I came out of the store 2. check engine light came on (4cyl. Misfire) but cleared itself after 100 miles 3. while sitting idle at a red light, the dash warning light lit up and flickered as well as chimed for a minute. 4. while cruising on the interstate about 70mph, the Jeep shut off for a few seconds and turned back on before I was almost rear ended by the vehicle behind me.

Just over a month ago I was going to work, and noticed that my turn signals were not working. I tried moving the turn signal up and down to no avail. I also noticed that my headlights would not come on. I pulled over and thought maybe a fuse went bad or something and found every single fuse to be fine. I then also noticed that the digital compass readout on the dash was not functioning, and I could not scroll through the menus with the main computer using the steering wheel controls. The hazard lights would work properly...and the lights would flash properly when I locked the doors with my key fob...which told me that the circuit was still working. After about 25 minutes of fiddling everything suddenly started working again. The next day, while at work I went to lunch, and when I returned to work as I pulled into the parking spot, my windshield wipers randomly turned on without me turning them on...and I could not get them to turn off...even with the engine off. I had to disconnect the battery to get them to go off. I took it to the local Jeep dealer and they found that it was the tipm I figured I do have a new unit and should be fine. That fantasy was destroyed yesterday when I went to go home from work, and suddenly my lights would not turn on...then got stuck on and couldn't turn them off...and my windshield wipers would not turn on at all...and the turn signals would not function...all while going down the interstate. I live in Virginia, and we are in the middle of a huge rain event, so the wipers and lights for sure needed to work in order for me to drive home. I had to disconnect the battery to get everything to turn off. After doing that...the headlights will not turn on...and the wipers remain the same and not working. Needless to say I had to get a ride home after I made it back to work...having to leave it at work.
