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.

I understand that this may not be in the NHTSA's arena but I wasn't sure where else to turn. Around the 21st of November 2014 the headlights, blinkers, cabin lighting and cruise control stopped working. I took the vehicle into capital Chrysler Jeep Dodge in garner nc on the 25th of November. The dealership diagnosed the problem as an electrical cluster in the instrument panel shorting out. The part is an exchange part and one of Chrysler's vendors would send a new part calibrated to my mileage to replace my shorted cluster and they would send my cluster back to be repaired. My vehicle was not allowed to be driven, despite physically working, because the new clusters mileage had to match the vehicles mileage and they had already submitted the mileage to the vendor. Around the 5th of December I was informed that the part was not going to ship from the vendor until the 19th of December. On the 19th I was informed by capital Chrysler Jeep Dodge that the part had not been shipped by the vendor and that they weren't expecting the part until after the new year. Today I received an update that the part is not expected to ship until the 12th. My case number with Chrysler is [xxx] and I give you permission to contact them about this incident. The part causes the lights and blinkers to not work. Chrysler is putting cars on the road that they aren't able to repair to a safely derivable condition in a reasonable period of time.

Parked vehicle in garage on Saturday afternoon. Went to start it back up and the vehicle had no dash lights, turn signals, horn, brakelights, heated seats, etc. Had it towed to dealership on Monday October 20th. The dealer said that the cluster was out and it would take a few days to get one. At the end of the week they told us it would be Nov 1st. I checked in on Oct 30 and the dealership said the part was now tentatively scheduled for Nov 22. Opened a case with Jeep and have a case manager who told me today that the new tentative date is Nov 28. The parts seem to be unavailable and our Jeep has been inoperable for 33 days with no end in sight.

The contact owns a 2012 Jeep Wrangler. The contact stated that the instrument panel cluster failed to work. The contact noticed an intermittent short occurring upon activating the parking lights, fog lights, headlights, and tail lights. There were also no audio controls, the horn would not sound, and the power steering was inoperable. The vehicle was taken to an authorized dealer who held the vehicle for several weeks and indicated that the instrument cluster was not available. The contact was not given a timeframe as to when the part would become available to repair the vehicle. The vehicle was not repaired. The manufacturer was notified of the failure. The approximate failure mileage was 33,500.

2012 Jeep Wrangler unlimited sport; 1st incident with hot oil message, resulted in dealership fixing the recall they all of a sudden had parts for (that were on back order for months-and for a recall). When I told the dealership I had a case id with Chrysler, they changed their tune and had the part(s). This was at 26000 miles. 2nd incident: I had driven to NY from SC with no issues while driving. Next day, cold start, hot oil warning. Took to a local auto repair shop and they "cleared the error" stating there was no apparent cause and they "didn't know why" the error occurred. 3rd incident: Called dealership I bought the Jeep from and told the guy (whom I know by name) that I was having the same problem, "hot oil message." He stated, "hot oil message, I don't know what you're talking about!" really"?" he was clearly lying, and I knew right then he was of no help to me. So, I went to the nearest Chrysler in a town 15 minutes away where I had moved to as it was closer anyway...letting the liar-part go, thinking the other dealership would surely do the right thing. This is at 34000 mi. The dealership has my Jeep currently and told me today that the dealership I bought it from wrote "added computer to Jeep, " as the supposed fix for the original issue (recall). The guy at the closest dealership told me the computer wouldn't even "talk" to him so he couldn't diagnose the problem until he figures out how to get the 1st computer to "talk" to him so he can get to the 2nd computer and try to diagnose an issue with the 2nd computer. Got a call this afternoon that it was driven around town with no problems after clearing the error message again. Awaiting final results now. I'm 2000 miles away from being out of warranty. Researching internet reveals numerous accounts of same issue with many people barely escaping engulfed in flames Jeep. This is an issue. Class action sought.

One morning the controls, horn, & I'm assuming, airbag stopped working (no lights or functionality). Just noticed the first time going out for the day. The removable hard top panels where off, and some dew was present in the air earlier that morning.... but it's a Jeep. The horn honked from the steering wheel once and then no more. It does still work when locking the doors and such remotely.

Ignition switch ? I was driving with my family and the car shut itself off. The engine stopped, the dash panel flickered, and then I lost all power. The brakes started losing pressure and my swaybar disconnect became disconnected. 1.5 seconds later the Jeep came alive and I had all the lights on the dash light up with warning bells like you do when you start the vehicle. This happened 13 or so times on the way home. It's currently at the dealer getting fixed. While I was there this morning there were 3 others with Chrysler group vehicles with the same problem. The Jeep forums also have several posts about this.

Purchased my Jeep Wrangler in may of 2012. Since purchase there has been numerous instances of the wipers turning on when in the off position. Wipers make a single pass and stop. This problem occurs at all speeds. It also occurs at times when the turn signal is activated. I brought in for service and the dealer replaced a switch. But now the problem is back again. Also, when stopped I am unable to view videos on the dvd player. The player has been replaced, but now it is doing the same thing.

After commute of 35 - 40 minutes from work I pulled into my garage and closed the door down for the night as usual and went inside. I did smell a slight burning smell but thought it was related to outside fridge that failed. After being inside a few minutes we heard a noise coming from the garage. I went to check it out and found the starter on the Jeep was spinning on its own. My wife noticed smoke and then flames under Jeep. I managed to get Jeep out of garage and fire put out and disconnected the battery. The fire was basically contained to the area around the starter and related wiring/hoses. The Jeep dealer picked up the Jeep and has it now. I contacted Jeep factory customer representative rep with the specifics of the incident and was told my file would be turned over to the "special investigations" department. I can't imagine what the outcome of this incident would be had we not heard the noise coming from the garage or if my commute had been an additional 20 -30 minutes longer.

My son purchased (leased) his first new vehicle (Jeep Wrangler) in mid-2012. It developed a problem with the windshield wipers as they will not turn on. This concerned me as this could be a safety issue if he were to drive the Jeep in snow or rain. Initially, the dealer's service department mis-diagnosed the problem and we were told the wiper motor needed replaced. Once that was replaced, we are now told the tipm module is bad and the part is on national backorder. I called Chrysler for help (minimal support from dealer as they asked me to follow-up) and it appears the order # the dealership provided me with was for the wrong part. Now, the dealership told me they are expecting a shipment of the part in may, 2014. I called Chrysler back and they are now working to expedite (again) but it may be a week before we even have a date. In the meantime, it is unsafe to drive the car and the dealership will not offer a loaner. Instead, they asked me to contact Chrysler to complain about this to try to expedite the part.

Driving & notice that window started to frost up, at the same time notice that the heat was not getting warm after driving for over 20 mins. Turned the defrost on and it started to frost more, put my hand to the blowers & notice that it was blowing cool air. Double checked that I had the heat on and put it to high and it continued to blow cool air, reached over to the passenger side and it was blowing warm air. Made an appointment took my vehicle in as it already had a recall on it for something else explain to them what was going on with the heater, they said that the part for my heater would take 2 days to get in & they would call. One week later had not heard anything, went back to the Jeep dealership(Colorado Chrysler Jeep) service & asked about the part, was told that it was nothing put in or shown about my complaint about my heater.set R another appointment to bring my Jeep in to have the heater repaired & was told it would take 4 hours, after being there for over an hour they said it was going to be a 2 day was a recall but not a recall & that they would be replacing the radiator and heater core. Appointment for 1/3/14 and was told it would be ready on 1/6/ or 1/7/14. My Jeep was not ready until 1/22/14 and when I picked it up on 1/23/14 they told me they the flushed heater core, radiator and overflow tank...flushed entire system filled and bleed system with new coolant and checked temp at 155 degrees. That should fix it and if it did not then they would replace the radiator and heater core. Then got in the Jeep let it run for over 8 mins heater on left side was stilling blowing cool and right was blowing warm. Took over 18 mins for the left side to blow warm but was not as warm as right side. Taking Jeep to different Jeep dealership service department tomorrow as the service simply show that they did not do the job they should have.

We could not start vehicle with only the center brake light working. The tow truck driver had to disconnect drive line to tow vehicle to dealership. The dealership diagnosed as tipm failure (total integrated power failure). Numerous complaints on internet were found with this same failure. We are very concerned of potential for car crash since all lights and vehicle are disabled without warning. If you are successful to coast your vehicle of the road there is still a danger of being hit by another car since the light are disabled. Also occupant cannot lock doors to defend against criminal activity. One more point is that this is an off road vehicle. We had just be using it in a very remote location. I don't know if we could safely get ourselves back including the vehicle from this very remote location.

On or about 10 am on 8-16-13 our air bag light went on and all steering wheel functions quite working. About 20 minutes latter the air bag deployed. The edr system reported that, no airbag went off and there is no recorded event. This from Jeep corporate investigation. The SRS module is also fine and has not triggered any event. This leads back to the clock spring and a short that they never even considered at the investigation of the know part that was faulted/failed.

I have a 2012 Wrangler sahara 4dr and this past week I had to tow my Jeep into a dealership in texarkana. I was driving 45 mph and not trying to gun the rpms. I had total shutdown but was able to get off the road. The dealership hooked it up and told me that my asd 25 amp fuse had blown but couldn't figure out why. My Jeep ran okay for much of the day but by night it blew another fuse as I accelerated from a green light and into the intersection. I replaced it with another 25 amp fuse but fear that if I put a 30 amp in that it would be too much for a burn out but I wanted to make sure I got home. I drove back home (an hour drive up and down hills) and it seemed to always want to ramp up the rpms suddenly. I would love to know if anyone else has had this kinda issue? I have less than 25,000 miles on my Jeep. Update... I have now had three fuses blow and two tows to dealerships because I couldn't keep a good fuse. I hope someone can please help me point out the direction the dealership needs to be looking for. This is getting frustrating. It seems to blow a fuse when I hit any type of bump in the road. No electrical mods were made except my warn winch, which was installed at the dealership for warranty reasons. Currently my Jeep remain in a tow yard until tomorrow where they tow it back to the dealership * no warning lights are indicated * new air filters * no electrical mods * factory sound system * rides rough * when fuse blows, total vehicle shutdown occurs including power steering and brakes.

I experienced a serious problem with my 2012 Jeep sahara. After accelerating and passing another car while driving, I lifted off the accelerator, but my Jeep continued to accelerate. I tapped several times on the accelerator, then tapped the brake a couple of times in case the speed control somehow engaged. I then tried to see if I could lift the accelerator from below with my foot, but it wasn't depressed. The Jeep was continuing to accelerate and at this point I was going well over 80 mph. Finally I was left with no choice but to depress the clutch and take the vehicle out of gear. I quickly shut down the engine as the revs went through the roof. I coasted onto a side road and attempted to restart my Jeep, but it wouldn't turn over. I turned the ignition to the off position and removed the key, put the key back in and turned the ignition at which point it turned over and after about 5 or 6 secs it finally restarted and everything seemed normal. I checked around the accelerator and the floor mat was securely in place and there was nothing around the accelerator to cause it to stick. I have never experienced anything like this before in my life and am 110% sure that the problem was not driver error. My feet were completely off any of the peddles while the Jeep continued to accelerate and as I had a clear road ahead of me, I very methodically and calmly took the actions I outlined above in the attempt to reduce the engine speed with no affect until I finally had to shut it down.

I bought my 2012 Jeep Wrangler unlimited sport in November 2011. It was working just fine until the summer of 2012 when my wipers would turn on all by themselves for a few seconds, and then off again. This happened several more times during the summer. In addition, the radio would just power off. The only way it would come back on was to hit the top of the dash and it powered back on. Took it in and they flashed a module which stopped the wiper issue but not the radio problem. This was July 2012. After that in same month, I noticed an engine light came on solid. Took it in, they reset it saying it was a cylinder #2 misfire. People on were talking about it too (see jk section and look for "ticking pentastar" thread). It was the biggest thread actually. Apparently, over a hundred owners on just this site alone had to have their head replaced. Wtf? the light came back on a couple days later so I took it back in. They confirmed the same result and told me they would order a new head. The local dealer here in savannah (hoover) told me it was in. Took in the Jeep and they said it would take 2-3 days. Big lie. After 3 days, I called to get status and they told me it would be 2-3 weeks!!! there were several people in front of me with same issue and only one guy fixing them. With a major issue like this on a brand new vehicle, this calls for a class-action lawsuit. I get small glitches happening but a new head"?" they did not change anything on the 2013's so this will likely be a huge headache for Jeep. Be warned!!!!
