Wrangler 4WD 6-cyl

  • 23,000 miles


While driving on the interstate, I accidentally bumped the keys of my Jeep Wrangler unlimited with my knee, and the key turned counter-clockwise enough to turn the car off. Obviously, when the car turned off, the brakes and steering lost power. Luckily, there was no traffic around me, and I was able to carefully coast to the shoulder and re-start my car. My vehicle is manual, so I could have restarted from neutral, but based on discussion boards, automatics do not have that luxury. Doing a quick google search for "Jeep bump key" yields many discussions about this same problem. I understand that Jeep currently has a recall for this problem in commanders and Grand Cherokee, but there is nothing for Wrangler. I called my dealership, but they will not diagnose or replace anything for free without an active recall. I am 6' and do not sit excessively close to the steering wheel. My key chain is not large or cluttered, and it should not be that easy to turn off my Wrangler accidentally.

Purchased vehicle 3/31/15. Put 400 miles on vehicle and noticed burning oil smell. Checked underneath and noticed significant oil leak all around engine coming from the upper part of engine. Took into shop and they diagnosed problem of the oil filter adaptor part#68105583aa being cracked and oil pumping out of it. They called dealership(dewayne lane) in wa and they advised they "had plenty of those parts". mechanic then said, "oh! it's a recall then." Dealer then stated, " we sure replace a lot of those."

I noticed a burning smell a few nights ago before noticing an oil spill in my garage. I looked under the help and saw oil everywhere! I wasn't sure where it was coming from. It looked like maybe a seal busted from the oil pan. I took it to the dealership right away since it was still under warranty. There is oil all over the rear of the engine, I feel it will eventually start a fire! this should be recalled since there are many Wrangler and other models with the same part, having the same issue!

Noticed oil in the garage after finally being able to park inside. Called Jeep dealership in niagara falls, NY but they were unable to schedule me an appointment for 5 days. The snow/ice in the driveway melted and I discovered oil stains on the cement pad where I had been parking. I was able to get into the Jeep dealership in batavia, NY today and they called with the bad news of a cracked oil cooler spraying oil all down the back of the engine. Isn't this a fire hazard. They have replaced 4 on other vehicles with the same engine this year (2015) already. Thee should be a recall with a proper replacement. The current replacement is oem stock.

Oil housing cooler was apparently cracked and leaking oil onto my engine. The cel came on and vehicle itself gave no error codes. Made an appointment and took it to the dealership. Probably put 40 miles on it in between not noticing oil loss being parked on the street. Spouse noticed loss of acceleration during trip home from work. Jeep didn't seem to be running any different so drove it to the dealership. I don't know how low my oil pressure was and if it caused damage to my engine. Did notice a good amount of oil on the ground after the fact.

Burning smell, oil spots and puddles under vehicle. Dealer diagnosed oil leak coming from cracked oil filter adapter housing. Part is defective and allows significant and dangerous amounts of oil to collect in the engine compartment. Technician found valley of engine full of oil, under vehicle, on transmission and oil accumulated in the skid plates under the vehicle. Oil accumulation poses significant danger and fire hazard with potential serious damage to vehicle engine and its occupants in the event of engine compartment fire due to accumulated oil in the engine valley. Chrysler case manager and service manager acknowledged part is a manufacturers defect. Part was replaced under warranty. Dealer reported they are seeing 2014 vehicles come in with this problem.

Burning smell of oil, part was cracked. Dealership even said it is a poor design. This needs to be a recall. This could've been a fire or an engine disaster with the amount of oil coming out of the vehicle.

I experienced the oil leak from the oil cooler. Replaced with the ab part. This could potentially be a devastating incident. Either too far away from dealer\shop or a fire. The amount of oil leaking was absurd. Clearly this should be a recall.

I have a 2014 Wrangler jk with 10,900 miles and I have a 5 mile drive to work. Two days ago, January 14, 2015 as I exited the vehicle, I smell burnt oil. I lifted the hood, I don't see anything like oil. I looked underneath for a drip or puddle, but I saw nothing. As I left work later that afternoon, I looked under the Jeep and there appeared to be a slight puddle of leaking oil. I drove 5 miles home. After I got there, I observed a good sized oil puddle on the driveway midway under Jeep with smoke coming out of the exhaust! I had Jeep towed to dealership and I was I just advised that it was the oil cooler/adapter housing. I had 10,900 miles on odometer when it occurred. I hope Chrysler engineers a replacement part fast! otherwise, the fine folks at Jeep may be looking at catastrophic engine failure and/or fire from oil coming in contact with hot engine or drive line parts on all of the my 2014 jks! this is a known issue that was first reported in May 2014.

I started Jeep, the radio channel mysteriously changed, drove approx 1 mile, came to a stop light at a busy mountain intersection and the entire Jeep blacked out, I lost all functions, we were almost rear ended and T boned at the same time, returned the Jeep to park and restarted. I took the Jeep to dealer they said they couldn't recreate problem, I drove Jeep off the property only to have it die at the first traffic light, put into park restarted only to have it die again. Finally made it back to Jeep, they've had it for a week and they claim they still cant find the problem. I don't trust the vehicle nor do I feel safe driving this vehicle in the mountains which is where I live. Also note, the entire vehicle lost all power, so does that mean the airbags wont deploy. This is unacceptable.

Vehicle is leaking oil at a rapid rate and smoking - could catch on fire cannot get it into a dealership in my area - was turned away because of lack of room/overcrowded. Warranty is trying to find a place to take it to but in the meantime I have nothing to drive and have a job and a child to get to school.

Developed severe engine leak. Diagnosed it to be the oil filter housing filter cracked. Required new adapter part number 68105583aa. This could cause a fire or engine being drained of all oil. This appears to be a known issue after doing a google search.

Jeep completely died (lost all power, including all electrical, brake lights, panel lights, etc) in condo parking lot. Got out to start pushing it back to parking spot, and a few seconds later the door chime started and power was restored. Radio was booting up from cold start (showing garmin logo). Restarted car, it turned over and started normally. Started driving forward again, and in about 20 feet, it completely died again in the same way, and came back to life about ten seconds later. Decided it was not safe to drive, and was able to restart again and reverse to parking spot. Jeep was towed on November 3 and repaired on November 4 when the part came in. I was told that the tipm was replaced with a new version that didn't have the same type of problems.

First time it happened, I was pulling out of a red light and it seemed the Jeep wouldn't shift gears, the rpms revved up and it seemed as though the transmission was not keeping up with the rpms. This continued for a couple seconds and I pulled to the birm of the road and put the Jeep in neutral. I then proceeded to put it in drive and pulled out. I took my Jeep to the dealer (Jeep in newnan ga) and they told me nothing was wrong. The computer didn't diagnose any problem. This has since happened two more times. The last incident was on October 3rd when my wife was driving. The person behind her almost wrecked into her.

Observed oil under the vehicle. Suspected that the oil cooler was leaking based upon others with the same problem. Observed a large puddle of oil in the valley of engine at the oil cooler. All this was observed after the second oil change (dealer). Parts manager at dealer stated this is a big problem on the 2014 models with the 3.2 and 3.6 engine. Depending how large the crack is on the cooler this could cause all the oil to be evacuated from the engine causing a fire with the hot exhaust or seizing the engine causing a crash. The oil filter/cooler was redesigned for the 2014 model year. At this point it seems to be affecting the 2014 model year.

Wrangler 4WD 6-cyl

  • 15,550 miles
I took it to big O tire to have the ball joints replaced as I knew that since I have over size tires and a lift kit that they would not be covered under warranty. I have been smelling oil for a couple of days, and checked it when I left winslow AZ. To go home to kingman AZ. And it was just a bit low. So when I picked it up from big O tire for the ball joint replacement they told me it was 3 quarts low on oil (that's a 186 mile trip) and they filled it, I took it straight to martin swanty Chrysler Jeep in kingman AZ. Which is where I live. They looked it over and told me it was a spill from when I had the oil changed at oil can henry's. they cleaned it up a bit and charged me $72 and told me I was good to go. I took it to the car wash and flushed the engine valley out really good and drove it home. I looked in the engine valley and verified that there was only water in the valley around the oil filter, but when I got home it was full of oil again, so I goggled the problem and found this on Wrangler forum and searched for 2014 jku oil leak and found it to be a oil cooler leak that looks like it is common on the 2014 models and most dealers don't know about it "??" this is Friday 09-12-2014, this is my work vehicle as I work pipeline. I will take it back to the dealer Monday.
