Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

July 26, 2016, we took our 2012 Jeep Wrangler to the dealership after the ABS and trac lights came on. The dealership showed a C102A code and a U140B code. They replaced and programmed the left rear wheel speed sensor, feeling that would solve our problem. On August 18, 2016, in stopped traffic, on a major state highway, the car lost power. We were able to restart the vehicle, but by the time we got it to the dealership, no codes were evident. On September 18, 2016. Driving 60 mph, on another state highway, the vehicle lost power. Fortunately it was a Sunday afternoon and traffic was light. We were able to coast to a side road and after about 4 attempts were able to get the vehicle restarted and drove about 2 blocks to a safe place. We had to contact a tow truck to carry the vehicle 10 miles to the dealership. The service technician was unable to get the vehicle to recreate the code, so he took it home for about 3 days, finally having the vehicle lose power and was able to get it coded. The diagnosis was a tipm shorting out. There was also a damaged clockspring. Both parts were replaced. Total of both invoices = $1,752.25.

Windshield wipers stopped working on the highway in the middle of a thunderstorm, creating a hazardous situation. Took the vehicle into the shop, had the fuses checked, wiper motor replaced, windshield wiper switch tested, and nothing fixed the issue. The issue turns out to be a faulty tipm (totally integrated power module), and will cost over 1200 dollars to replace. This appears to be a widespread issue with Chrysler vehicles.

Just noticed while driving, all of the controls on the left side of the steering wheel are inoperable. These include the radio, bluetooth phone, information menu, reset, etc: Upon further examination I also noticed the horn no longer works. Unsafe and will not pass state inspection. Inquiry by internet search indicate possible clockspring defect, but that is inconclusive so far.

Wipers turns on automatically when in the off position, same with ac, stereo resets by it self. This happens no matter what the shift position is. No matter if the car is running or in parking mode.

The fuel pump relay on the tipm module failed (total integrated power module). This for the 2012 Jeep Wrangler unlimited isn't part of a recall and it isn't something covered under the power train warranty. The Jeep started turning off at low idle. This happened for backing out of a parking spot or at a stop light. It now happens when going down the road where the vehicle turns off at random. It isn't safe to drive until it is repaired. I am working on the repair now.

I just left work and had traveled less than a mile when my engine shut off. I was only traveling 20mph and coasted into the first open driveway I could find. I opened the hood to a lot of smoke and a small fire from my wiring harness. My 2012 Jeep Wrangler sport is completely stock and always maintained through my local Jeep dealership. The official word from Jeep was that my starter shorted out which caused my wiring harness to overheat and catch fire.

The sudden failure of turn signals, windshield wipers, headlights, taillights, brake lights and all controls on the two stalks and the steering wheel. I do not know when it happened and realized it when I noticed the lack of sound and blinking dash light on using the turn signal. No fuses were blown.I do not drive in the dark much.I am having it repaired today. The service writer said it was a computer. How can Jeep tie so many essential controls together? if it had occurred at night in the rain it could have been catastrophic. Perhaps it has already happened to someone.

Air bag light came on while driving down a local city street. Took it in to the dealership and it was diagnosed as a faulty clock spring rendering the air bag inoperable. My complaint is that NHTSA already has 2 recalls on this problem but for right hand drive Wrangler only. My Jeep has the same problem, concerning the same parts, for the same reasons the right hand drive air bag failures occurred. Jeep refuses to cover my Jeep under these recalls. NHTSA campaign number: 13V176000 and NHTSA campaign number: 11V528000

The tipm unit went out, causing lots of issues. The issues we┐re aware of are: The doors wouldn't lock, shifter was stuck in park, radio/cd/bluetooth wouldn┐T work, and the front headlights wouldn't turn off leading to a complete drain of the battery. Thankfully, the vehicle was parked and this didn't happen while we were driving it (it could have been very dangerous if it did). It cost us $1100 to replace the tipm unit, which was a huge financial burden on us, but even worse was that we had to go without the Jeep (one of our main means of transportation) for almost two months because there's a waiting list for the replacement part. We checked with 3 different repair shops just to be sure, and all said the same thing: 1.) that there's a waiting list at least 40 people long for this tipm unit, and 2.) that they've been seeing Jeep Wrangler left & right for this same exact problem, and there's a waiting list because the part can't even be manufactured quickly enough to keep up with the demand. I know the tipm unit has been recalled for Jeep Cherokee, but why not Jeep Wrangler when this is clearly a major issue for it as well??

I was having electrical issues with my 2012 Jeep Wrangler. Specifically my windshield wipers were not working. It was snowing outside and they just wouldn't work. I had to manually get out of my car several times to clear the snow before I made it home. I got the motor replaced but it they still were not working. I took it to the dealer and they said that my entire tipm (totally integrated power module) "went bad". they told me that the could not order the part because its on back-order. I called Jeep and they said that the part was on back order with no estimated time of delivery. The tipm controls all of the electronic controls on my vehicle and I can not drive without it. It is a 2012 so I am surprised that this part is failing, let alone unavailable from the manufacturer. Furthermore the part alone is $850 and not covered under warranty. I did some research online and it looks like there was a class action lawsuit filed against Chrysler/Jeep/Dodge for this part being defective but it only covered certain makes/ years.

Airbag clockspring was replaced under recall M031 in early 2012. The part recalled had failed again causing airbag light to be illuminated, loss of speed control, loss of steering wheel audio controls, loss of horn, and loss of "step" and "reset buttons for the information center. This issue started out when turning the steering wheel in the left or right position and within a few weeks has became a constant problem to no avail.

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.
