Intermittent stalling has occurred 4 times while the vehicle was in motion driving straight. 3 times occurred on city streets and 1 of the 4 times was while merging into traffic on an interstate at interstate speeds. The vehicle restarted 3 times after stopping and placing the vehicle into park and cranking for about 5-10 seconds. The last time, the vehicle would not restart immediately and took around 2 hours to restart. There was no warning prior to each time, no stuttering, rough idle, acceleration, decelerations, etc. The dealership service department said diagnostic trouble code reported crankshaft position sensor failure, but testing could find no issues each time. Service manager requested that the vehicle be left indefinitely for them to test drive until the condition could be witnessed by technician.

Drove 1018 miles Jeep was running fine. Stopped at a hotel to check in. When I went back out to start it, the check engine light came on and stayed on and was a solid light (no blinking). Drove it thanksgiving day and took it to a dealer on Friday with the code P0304. Mechanic tells me that it needs a new cylinder head and is not safe to drive back home 1018 miles. I learned later that this is a known issue and Jeep issued a lifetime warranty covering up to 2013. After much research and reading, the issue still continues through the 2016 models. I called Jeep to ask for some assistance since I am 1018 miles from home and having to stay in a hotel for 10 days with no loaner or rental car and the repairs are estimated at $4850 (the cost at home in Texas would have been $2600) and Chrysler said no! this is a known issue and continues to he a known issue. Chrysler Jeep should be fixing the problem or extending the lifetime warranty for this issue.

While checking my fluid levels, I noticed oil in the vicinity of my oil filter and in the valley. With little search, it was apparent, I had a poorly designed oil filter/cooler adapter. Took it to the dealership and again, to my surprise, they did not honor the manufactures warranty but of course charged me 160 bucks to tell me what I originally told them. I then asked if they had the part available, guess what they said?? of course, they don't have any due to national backorder. Mind you, my Jeep has only been dealership touched and at 35000 miles, this should not be an issue. I am forced to drive my other vehicle due to fear of my engine bay igniting, as you and I both know it has sadly happened to many others.

Noticed smell of coolant when vehicle was parked. I was not able to locate the leak. There were no puddles of coolant or detectable drips. Took vehicle to the dealer. I was told radiator needed to be replaced and would not be covered under warranty. Vehicle has @ 26,000 miles. 3 year warranty expiered 5 months ago. Vehicle has been dealer maintained since purchased new. Contacted Jeep customer service to request assistance. I was told sorry can't help warranty has expired. There are no indications of abuse or outside damage to radiator. Radiator failure is an obvious manufacturing defect.

While driving down our Jeep Wrangler down the highway my husband stopped at a red light and said he heard something hissing then he saw flames coming from under the hood. At that point the Jeep would not steer or anything so he shut it off and my husband and son got out of the Jeep. Moments later the entire front end of the keep was engulfed in flames.

Radiator reservoir was found to be low at around 9,000 miles during first oil change. Along, with a slight smell of antifreeze when the vehicle was warm. The reservoir was top off with no signs of leaks from reservoir and smell was thought to be coming from reservoir. Both issues continued with no signs of visible leaks upon inspection of coolant system. So issues was thought to taken till reservoir was found low again at around 36,000 miles still no signs of leaks, and reservoir was top off. Continued to monitor with no signs of leaks until the smell of antifreeze began to get stronger and more frequent when vehicle was warm. After internet search, reading about people with similar issues the problem was found. On, engine side of radiator behind fan along the end cap there was noticable signs of leak. Radiator was replaced. Fca informed.

I was driving on the 91 freeway eastbound in California. Somebody wave me to stop. The car got on fire while driving. As soon as we got out we saw the flames, it got on fire so bad that only the fire department was able to extinguish it. Some truck drivers tried to extinguish but they couldn't. it only had 24000 miles on it because I only use it on the weekends. I took really good care of it. Needless to say it was the scariest and saddest moment of my life. I'm still wondering what happened

2015 Wrangler sahara engine fire I have just purchased 10 days ago a certified 2015 Wrangler sahara certified pre owned from avondale Dodge in phoenix AZ. It was a gorgeous hardtop grey, with 30" tires, mags and an led light bar. I had been looking for 3 months and finally found my dream Wrangler. Still with a temp plate and one tank of gas in it the engine caught fire sitting idle at my work. I had literally drove from the dealer how it happened. I had gone for lunch with co workers and parked in covered parking at my office in phoenix. There was no foul smells and the vehicles performance was normal. I was notified by the facilities managers 2 hours later while in a meeting that fellow employees saw it smoldering through the grill and phoned the fire department. When I got outside the engine compartment was completely charred.

I am having difficulties with my brand new purchased Jeep Wrangler and it has been in and out of the dealership since September with no resolution. This Jeep is 19 months old and we bought it brand new from sahara Jeep. Despite the fact that it does run the engine suddenly chooses to lose power while I'm driving and accelerating or decelerating is not an option. Not really safe especially when my daily commute to and from work is over 20 miles one way on highway speeds. The engine has stopped about 6 times and two times of those has been on highway speeds which is not a safe place. I have been lucky that when it happened that I have not been rear ended or even worse have caused any accidents. I have continuously brought the vehicle back to chapman and they are unable to find any issues and then now the vehicle is at sahara and I am getting the same answers. Although error lights have come on and I have given the dealerships those they are still unable to diagnose what is making the vehicle engine suddenly stop.diagnostic testing keeps coming up negative. I was given a flight recorder to attach to my Jeep to help assess the issue. The vehicle died and I was able to successfully run codes through their recorder (supplied by Jeep) and had the vehicle back at the dealership the next day. I was told that their computers were down and unable to read the codes but they did capture something but had forwarded it onto corporate to read. A couple days later with no update I contacted corporate and was told that they were unable to read the codes because their system was also down and I would have to do it all over again.

Oil filter housing. Dealerships are not replacing this faulty housing unless it's made a nationwide recall. This is a problem for quite a few chrylsers - Jeep. Please look into the 2014 & 2015 oil filter housing cracks and dealers will not fix if not under warranty and if they have not changed oil.

I keep getting a stability control light and that causes the ecb light too pop and then I have no steering wheel controls. This all started after I tried to superchip my 2015 Jeep Wrangler. Sense then my Jeep has been in a local shop for about a month and they have had the brain reflashed and have changed gears for the 4inch lift and much much more. I was driving 65mph when the stability control first tries to take control of the vehicle, talk about scary...anyone out there have this or similar issues, please help.

Engine light comes on and remains on until dealer resets it. Code indicates that cylinder #6 misfire. Since Jun 20 2015 and up to 4 Jan 2016 the vehicle has been in the shop 7 times. Town time has already reached 24 days. So far they have replaced the cylinder head, removed the head a second time, updated software, and replaced the cam shafts, plus a number of other things. The star team at Chrysler/jepp has been involved with no success. First time the light came on and remained on was 18 May 15.
