I own a 2015 Jeep Wrangler. In mid-2019 I noticed the heating system was not operating well. For example, when I turned the heat on, it would intermittently send warm and then cool air out of the blowers. One 38 degree day, it sent out no heat at all. In October 2019, the anti-freeze fluid level was low and it was filled. In Dec 2019, the entire reserve tank was empty. No fluid was visible in the radiator when the radiator cap was removed. I have observed when the car has been driven for 3-5 miles and then turned off, there is a slight odor of anti-freeze. It appears my vehicle may have a defective heater core.

At approximately 12K miles I noticed that when the vehicle was started and moved from the street to the driveway and turned off before it could reach normal operating temperature, upon restart, there would be a puff of blue smoke from the exhaust. The dealership investigated and said that they could not duplicate the issue. At 20,500 miles the vehicle was running poorly and the check engine light came on. The dealership said a fuel injector had gone bad and they also found 3 bad engine rocker arms. The rocker arms were replaced under warranty. Incidentally, the issue with the blue smoke from the exhaust disappeared. At 28,000 miles the engine was beginning to develop an audible ticking noise. The dealership investigated and this time replaced 4 bad rocker arms. At least 1 of the rocker arms was the same one (#1 intake) that had been replaced during the prior servicing.

Vehicle shuts down completely. The interior still has power but the power steering and engine stops. It restarts but act like it is not getting any fuel. It runs fine after it is cranked until the next time it happens. It is very dangerous

My Jeep caught fire from the dash, reasons unknown. Insurance is investigating and fire dept put cause as unknown. Jeep is a total loss and my husband barely made it out of the vehicle before it was engulfed in flames. He was driving from school to home and about a mile from home on the highway about to exit. Consumer stated as he was trying to shift into neutral and pull the E-brake, he was burnt on his hand and a little on his legs by the time he jumped out. On the day of the incident, my husband drove approximately 5-6 miles to class (as he is in a technical school right now) around 6:30 am. As he was coming home, it started smoking about half way up the on ramp heading in the direction to the exit to our home, my husband said right before it started smoking it almost sound like that blower motor was making a strange noise, and he was headed home to look at it, but the noise quit right before it started smoking. He did his best to get it out of traffic, but as I stated, with it being a soft top, it went up in flames rather quick. The vehicle was serviced every 4,000-5,000 miles. My husband has a motorcycle, so the time spent in the Jeep was mainly in cooler weather or when it was raining/overcast. There were not issue leading up to the fire. We had taken it on short trips - longest distance was like 100 miles round trip, but hadn't done that in awhile. The vehicle was a total loss, state farm totaled the vehicle, we have not had possession of the Jeep since it was towed from the side of the road by whoever the fire dept called (allied towing). After that insurance had it towed to a location of their own. I believe my husband only had a sub woofer in the Jeep, you can see it in the back in some of the pictures. I believe at some point the stereo was changed but that was before we owned it and it was in our possession for almost 1 year prior to the fire. I have no contacted the fca, I wasn't sure who to reach out to for this issue.

Saturday morning at approximately 10:45 a.M. driving 4.9 miles to destination I asked as we were approaching parking "do you smell smoke?" I hit the breaks but there was no breaks. And then a combustion of flames came from wheel wells and hood of Jeep. We all jumped out and called 911 and tried to put fire of Jeep out with extinguishers. With no success. Fire department put fire out.

The contact owned a 2015 Jeep Wrangler. While driving 25 mph, all the instrument panel gauges illuminated and the brake pedal felt soft. The vehicle slowed down and the contact smelled smoke. The vehicle caught fire on the driver's side of the engine compartment. The contact pulled the vehicle over, opened the door, and the fire spread. The contact had to quickly exit the vehicle. A police report was filed and the fire department extinguished the fire. There were no injuries. The vehicle was towed to a salvage yard and deemed destroyed by the contact's insurance company. The dealer and manufacturer were not contacted. The cause of the failures was unknown. The VIN was unknown. The failure mileage was 59,000.

Radiator leaking coolant on driver side tank. I've smelled coolant since new but never seen a leak until warranty was expired. I currently have less than 30,000mi contacted dealer and was told simply no warranty. Reading about this problem online seems to be a common issue.

My 2015 Jeep Wrangler with less than 36,000 miles (current mileage is 31,000) developed a hole in the upper right (facing the vehicle) on the radiator. Only factory authorized antifreeze was in the cooling system. In fact, the coolant had never been touched since purchasing it new April 17th, 2015. This past fall I knew I had a leak and took it to the dealer. They said it was leaking oil around my oil filter and ended up charging me $46 for an oil change; however, the mechanic (pete) could not explain the leak. I felt the fluid on my garage floor with my fingers and honestly thought is was part oil and antifreeze. Now, on Wednesday December 26, 2018 they are going to replace the radiator and the dealer's estimate was approximately $800 dollars. In short, no radiator should blow a hole in the sidewall of the radiator with so few miles and time.

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.
