Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

problem #40

Nov 152015


  • 21,000 miles


Oil filter housing/cooler leak breaks on numerous low mileage Wrangler, mostly on or before 25,000 miles. Mine was at 21,000 miles when it crack and leaked profusely. This leaks spread quickly and motor oil was gathering on the exhaust pipe under the engine bay. This created smoke from the burning oil which could eventually lead to a vehicle fire. I was lucky enough to find the issue quickly and diagnose it. This also is an environmental issue, having fluids especially engine oil, leak onto roadways or other driving surfaces. Jeep has yet to formally admit to this issue, those several if not all dealers are aware of this issue in the 2014 year model. Cherokee owners are also reporting the same issue, and come to find out the Wrangler and Cherokee share this same exact part. Jeep has focused on cutting productions costs rather than safety. This needs to be addressed to Jeep and Chrysler immediately.

Noticed a burning oil smell and traced down the source as a cracked oil filter adaptor. Took it to a repair shop where they examined the part and verified that was the source of the oil leak.

Observed oil leaking from the bottom of the vehicle and was able to locate the source of the leak on the top part of the engine around the oil filter. The leak was caused by a crack in the oil cooler housing and oil was covering the top part of the engine and running down on to the transmission and the exhaust. My vehicle only had 9516 mi on it so I decided to check on line to see if anyone else was having this problem with 2014 Wrangler. I was able to locate at lease 50 other complaints with the exact same problem. This issue is just not an inconvenience but a safety hazard as well because oil on top of the engine and the exhaust is a fire hazard. This leak occurred both white the vehicle was moving and sitting still. The vehicle is currently being repaired at the dealer.

The contact owns a 2014 Jeep Wrangler. While the brake pedal was depressed, the engine stalled without warning. The vehicle restarted, but the failure recurred numerous times. The dealer could not duplicate the failure. The vehicle was not repaired. The manufacturer was made aware of the failure. The failure mileage was approximately 9,000.

  • 3,000 miles
Easter Sunday morning drove from country home 7 miles into town to church, no stopping and slowing down just a couple of times. Parked, locked vehicle and walked into church lobby. Stopped to speak to a man when he noticed black smoke in the parking lot. Turned and saw that it was coming from under the hood of my Jeep. Within a minute flames started. Fire department was called and responded within a few minutes, but not before flames from the passenger front side jumped onto the car parked next to the Jeep. Both vehicles were burned up and totaled. Flames started on the front right side (passenger).

Vehicle was taken to the dealership for an oil change, the employee told me there was a major oil leak. I had to leave my vehicle at the dealership so they could figure out where the oil leak was. I was advised that the oil was leaking from the oil adaptor and that there was a crack in the part.

  • 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.

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.

  • 10,300 miles
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.

  • 10,907 miles
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.
