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.

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.

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.

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.
