Twice, end of May 2019 and February of 2020 I had scheduled oil changes done at same dealer. By the end of those days, Jeep would not run, check engine light blinking and would barely start, not run. Both times towed back to dealership, both times under warranty. First time I was told a broken valve spring and valve cover had leaked oil into ignition system. Valve spring/cover work covered, tune up and redoing ignition system not...? was told to contact manufacturer, they told me to contact dealer. This time(2/2020) towed in, took six days to be told broken valve spring/valve cover but also a defective cylinder head. Also told cylinder head on back order, could be months. Vehicle is maintained according to manufacturers schedules, don't do tractor pulling with it, this appears to be a known defective, just like the bad radiators or heating system gooped up with sand. Thank you.

At 41,900 miles a noticeable clicking/tapping noise anytime the engine on. It came on suddenly and when mechanic heard it he thought rocker arms or lifters have failed. Had diagnostic and mechanic found 2 rocker arms were bad. Thankfully cams without damage per mechanic likely due to seeking repairs so quickly

- Winter Park, FL, USA

The contact owns a 2015 Jeep Wrangler. The contact stated that while driving at an undisclosed speed, there was an abnormal noise coming from the engine. There was no warning lights illuminated. The contact stated that the sound was more prevalent while the vehicle was stopped with the gear shifter in the park position. The vehicle was not taken to be diagnosed nor repaired. A dealer was not contacted however, the manufacturer was contacted and informed of the failure. The approximate failure mileage was 60,000.

My Jeep has a 38375 miles on it and I took it the dealer cause I kept smelling coolant and I thought I had a leak in the plastic anti freeze holder they put the truck on the lift and said I have two leaks on the seals why is that the car shouldn't have a leak in the radiator this soon the car is not old the car now smokes so I have now stop driving the truck this should also be covered under the warranty

- Pomona, NY, USA

Purchased 6/26/19 w/ 49K mi; tapping noise develops at 54K; personal, highly qualified/experience mechanic referred me to dealer - tap was engine issue. On 10/14/19 dealer replaced lifters/cams/rockers (warranty until 10/20/19). Not normal on vehicle w/ only 55K. Dealer aware of cylinder misfires on jks but did no diagnostic test to determine why lifters/cams/rockers failed; did not perform inspection. Ten days later, cel with PO302 (#2 misfire). Replaced plugs; coil code did not clear. Return to dealer who stated work was not related to previous work they just completed and acknowledged misfire is a common problem they routinely in Wrangler they service. Dealer also stated the 2011-2013 tsb extended warranty also applied beyond those model years to other engines from specific production runs but would not provide info. Filed complaint with Jeep cust care who said same - not under warranty, referred me back to dealer. Not asking Jeep to repair engine with excessive mileage or wear - I am asking Jeep to extend same coverage as 2011-2013 because Jeep has not corrected the problem. No engine with 55K miles should need the extent of engine work I've had done with low mileage. There are numerous documented complaints of misfire for Wrangler and class action suit filed for pentastar engine defects.

Oil filter housing has cracked and leaking oil. Appears to be widespread problem. Many Jeep built after 2014 seem to have the same recurring problem. The plastic housing is defective.

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.

Oil filter housing has cracked and leaking oil. Appears to be widespread problem.

Faulty oil cooling housing, oil is leaking from there

- Colorado Springs, CO, USA

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.

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.

Significant oil leaking from oil coolant housing on the engine. Engine started smoking thought it was on fire. Shut off car imediately and sent car to dealership

Cracked and leaking oil cooler housing

- Lexington, KY, USA

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.
