Oil filter/cooler housing developed a leak. Was told by mechanic that it is most likely cracked. Replacement part is on indefinite back order, at least 45 days. Leak is bad enough that I can not safely drive the vehicle. It has been sitting in the garage for 4 weeks.

Oil cooler leak. I lost over 2 quarts of oil after a short drive. The seals were also leaking into the injectors causing multiple cylinder misfire codes and check engine light warnings. No warnings from the oil cooler except the large puddle of oil under the Wrangler and oil coating the entire back of the engine and skid plate.

Jeep 2014 and older are issued a part called the oil cooler/filter housing which is prone to leaking oil on all Chrysler engineers using this part. This is defective and or a design flaw resulting in replacement and costly repair and is a reoccurring failure on all Chrysler using this part. This failed on my Jeep Wrangler with 48K miles. The part is approximately $300 to replace and over all repair at a non dealership is upwards of $1000. This issue needs to be a recall!

Oil cooler assembly has started leaking badly after 60,000 miles and is a fire hazard. This assembly is too fragile and requires taking off the intake manifold to access and replace, so it should not be a plastic part. It contains the oil filter which causes it to have torque applied every oil change and causes it to break prematurely. This is very common problem and I was told by the dealer that there were 25,000 of these assemblies on back order nationwide and he could not tell me when it would be in stock. My Jeep is now undriveable until the backlog is worked through which may take months. If this was a rare problem I could get the part and have it repaired. This problem has rendered my vehicle unusable. This is unacceptable and Jeep has known about this issue for years on multiple year models. Please investigate. There is no reason this couldn't have been properly engineered with a metal part.

I I will be driving and the car will go out of gear and looses power. I have to stop, turn it off and start again for it to work. This has happened 5 times in the last year.

I was driving my keep and started smelling oil and had smoke coming from under my car. I notice on my garage floor large oil leak. I picked up my disabled son and noticed it had gotten worse. I was forced to stop by my mechanic and was told my oil cooler adaptor housing was broken and leaking badly. I had purchased a mopar protection plan directly from company. When I called Jeep dealership they said I would have to bring it and let them diagnose it before they could decide if it was covered by my mopar care plan. My mechanic informed me that this was a common problem with this Jeep engine but they had not done recall yet. I call mopar and they would not authorized payment to my mechanic unless he call for authorization number. He called and they said no. This part needs to be handled by a recall if it's that bad. I was reading complaints on another site and they said it could lead to a fire starting because of oil leaking onto exhaust.

I get frequent oil changes and I noticed that the last two oil changes it started making this ticking noise. I brought it to my mechanic and he told me that after the next few oil changes it should go away. Than my other mechanic that heard this ticking noise said that it was serious and this has something to do with an engine part callled a lifter. I nervous when he told me that if it's not fixed the engine could seize. I just bought this Jeep from a dealer not knowing this was a common problem among Wrangler. I did my research and came to the conclusion that it has nothing to do with the mileage but more so on how the engine was built. I spoke to number of dealerships and they fix this common problem on all ages and mileage Wrangler. The estimated cost of repair would range from $2000 and up. I don't think we as consumers of this product should be repairing an engine problem from Chrysler. I don't have any pictures yet til the dealership opens up the engine

Arm rockers in the injun constantly have to be replaced. Giving the injun a knocking song.

- Bronx, NY, USA

While driving the Jeep shuts off. It is hard to steer and happens without warning. This has happened about 10 times in the last month. It does not throw a code so the dealer can not fix it.

- Lehighton, PA, USA

My car is as 54090 miles, dealership changed housing thermostat and replaced the thermostat housing adaptor. Stated my car has internal engine noise from worn rockers and lifters. Was safe to drive. Got a second option, my car has rocker noise coming from the right bank and can wear. Also some cylinder heads had to be replaced. This was an issue with the 2012 and 2013 models so Chrysler should be taking these issues seriously and extended and recalling all 2015 Jeep to do a maintenance check. I was told upon my independent review not to drive my car, to get it home safe and slow. I have reported the dealership to the BBB and filed a claim with Chrysler. This needs to be taken seriously.

Radiator leak, with less than 70K miles the hoses were replaced but still leaking with smell of antifreeze

- Stafford, TX, USA

First owner of vehicle. Issues began with engine light appearing/blinking & vehicle struggling to run within 15K miles. Dealership diagnosed as cylinder misfire & repaired. Has occurred multiple times over life of ownership- always diagnoses as misfires. At apx 75K miles, upon cranking & during operation, heater became inconsistent in operation & this is still an issue. At apx 80K miles, upon cranking & during operation, ticking noise from front passenger side began. Faint at first & became increasingly louder within several days. Out of warranty. Solid check engine light began to appear off/on, remaining on for 24-48hrs then off 24-48hrs. Air conditioner conditioner has about a 15 sec delay before it turns on at every crank & power light for A/C slowly blinks until after the delayed start. Mechanic found 2 rocker heads damaged & they were replaced. Light not on at repair & code could not be pulled. Within 2 days of repair, a faint ticking noise became present on drivers side. Has been a week & ticking is now extremely loud. I am one of many with parallel issues & request this be addressed as my year & VIN do not fall in to the approved extended warranty to cover these very same issues.

Air cooler filter (adapter) - leak. Common defect in all Wrangler vehicles. Danger to engine damage.

- Naperville, IL, USA

There's a leak coming from the oil filter housing unit and D it's causing a very noticeable ticking from motor at all times.

- Madrid, IA, USA

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.

- Rockton, IL, USA

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.

- Manheim, PA, USA

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.
