I have a Jeep Wrangler Unlimited Rubicon 2016 that suddenly lost power in fast moving traffic with intermittent miss fire and blinking check engine light along with smoke and smell of burning oil. Looking into the engine from the top a large, deep pool of oil was sitting in the middle of the engine and working its way on to hot components of engine and exhausts and smoking. This could have easily become fire hazard in high temperature desert environment where running temperatures and hot exhaust pipes could start a fire. The engine miss fire and sudden loss of power was checked to be failing ignition coils and plugs that are supposed to be warrantied to 100K miles. The Pentastar V6 3.6 oil cooler was leaking badly and its effect could have been disasterous for the engine and car safety. The Oil Cooler faulty plastic design on this engine is a well known problem that Chrysler is refusing to address as recall on Wranglers sold. There are hundreds of complaints and cases of failure of this plastic component on the internet and the dealers are all well aware of it and happy to charge $2k for replacement. Chrysler and the dealer refused to admit the faulty oil cooler design and also would not accept ignition coil and spark plug replacement under the Std 80,000 miles California Emission Control warranty that come with all engines sold in CA. Chrysler is hiding this faulty design on Wranglers but accepted it on other Chrysler cars.

2016 JEEP WRANGLER UNLIMITED SPORT. Vehicle has 41,500 miles. 3.6 Liter Pentastar V6. Gushing oil from oil cooler on to the exhaust and smoking to the point of catching fire. Known issue from what I am reading online. I guess Chrysler is waiting for one of us Jeep owners to die in a car fire!! $1200 to replace.....UNACCEPTABLE that a recall has not been forced on Chrysler!!!!

- Delray Beach, FL, USA

Oil filter housing/Oil cooler cracked. Dealership says its a common problem on 2014+ jeeps with 3.6 liter engine yet Jeep hasn't issued a recall. Dealer stated that this seems to happen around 50,000 miles on vehicle. No warning lights came on, noticed smoke coming from under hood when driving from oil falling onto exhaust. When pulled over large amount of oil was coming out from underside of Jeep. This happened with 43k miles on the vehicle which is right around where the dealer said they were seeing a large amount of failures for this part.

On thursdsy 5/13/2021 at approximately 5:15-5:20pm, I was dropping my daughter off to work and I got back on the road then through the U-turn to get back on the other side. I proceeded to enter the roadway initially about 10mph and all of a sudden, the Jeep accelerated to almost 80 mph and I smashed the braked and it would not stop at all. The RPM's were steady going up. I pulled up the emergency brake right before I almost rear ended the car in front of me at the light getting ready 6O go through the intersection. I was on the brake at the same time. Once the car finally came to a stop, the engine was still reved up. I put in park and turned the vehicle off with the ignition. I then restarted and was scared the rest of the way home. The vehicle was in motion when this happened. There was nothing under the brake. My floor mats were flush and flat and the acceleration was so scary. I feared for my life. I have not driven it since. I called the dealership and they told me to bring it in the next morning, Friday the 14th at 10 am but that theu would not be able to look at it until 7-10 days. I did not bring it as this was unacceptable. I will call back and speak with someone else for results. The tech even told me that this happened to his brother that also have a Jeep. There isn't a recall for this that I've found. Someone will lose their life because of this malfunction. This is a very serious safety hazard.

Engine oil cooler assembly leaking at back of engine. Oil leaking down back of engine and bell housing creating a possible fire. Very hot smell and smoking from engine bay

- Galesburg, IL, USA

The oil filter canister/oil cooler is cracked and is leaking oil. This is an environmental hazard. We have taken it to our mechanic and spoke with the dealership that it was bought from and have been told by many other part houses that this replacement part is on a 50,000 + parts back order and that it can take anywhere from 20-60 days to get the part in to replace it. The vehicle was stationary when we noticed the leak and never driven again after that. This tells me that this is a huge issue and that there should be a recall on this issue. I understand the manufacturing side of things but that is a large number for the back order.

- Pantego, TX, USA

My vehicle hasn't been driven much, I work from home, I noticed a pool of oil under it, took to dealership and he oil cooler is leaking.

- Oklahoma City, OK, USA

The oil filter housing is made of plastics and it cracks and oil leaks on to exhaust which could cause a fire and also environmental issuer due to oil leaking on ground. This is a big problem with the Jeep pentastar 3.6 V6 engine. After contacting Jeep dealers to fix leak they tell me the part is on back order due to so many Jeep and cars that have this part. The number they gave me is over 40,000 and time frame of getting one could be a month. This explains why Jeep drop power train warranty from 100,000 miles to 60,000. I noticed a little leak at 65,000 mile and now at 70,000 miles you have to keep adding oil or park it due to maybe it catching on fire. One dealer told me he had 30 vehicle sitting on lot waiting on part.I feel Jeep should have a re-call for this issuer. Now I have a Jeep that I can't use for a month or more if lucky.

Oil cool is leaking after cold weather

- Meno, OK, USA

Engine oil cooler is out and leaking oil everywhere. The vehicle is not driveable and the part is on over a 45 day back order. No company will ever take my vehicle in due to the part unable to be ordered. Everyone seems to be having the same issue. My Jeep has 62K miles on it and is my daily driver. This needs to be recalled.

- Owasso, OK, USA

The contact owns a 2016 Jeep Wrangler. The contact stated that while driving at approximately 45-50 mph, there was a burning oil smell detected inside the vehicle. The contact parked the vehicle and saw there was oil leaking from the vehicle onto the ground. The contact took the vehicle to an independent mechanic where the failure was diagnosed as a cracked oil cooler that leaked into the exhaust system. The contact informed a Jeep dealer of the failure but the part to repair was on back order. The manufacturer was not informed of the failure. The failure mileage was 70,000.

- Lockport, LA, USA

Engine oil cooler fail, extreme fire hazard. Small amount of oil found on driveway while parked, attempted to locate source by starting engine. Oil flooded out of the engine, streaming down the engine to the frame. Had my wife driven the Jeep to work it would've probably caught fire once the oil reached the exhaust.

- Portland, TN, USA

I noticed an oil burning smell and upon further inspection saw oil all over the undercarriage of my vehicle including the transmission and exhaust. Looked under the hood and noticed oil underneath my engine cover by the oil filter housing. So now every time I drive it smells like it's on fire. So I guess they are not worried about the people who buy their vehicles burning up.

- New Orleans, LA, USA

The oil filter housing assembly is made of plastic that cracks. This leads to oil leaking and several inches of oil sits in the V of the hot engine until it spills over. This is a definite fire hazard. Fca needs to recall with a redesigned part made of metal. I have already replaced mine twice in 1 yr. Replacing it with the same part is not fixing it. Failed at 29K miles and now at 42K miles. This is a $1000 repair each time. Mine was covered under power train warranty but this is unacceptable quality and practices. I noticed oil leaking underneath the engine again and this time I thought it was the rear main seal. I noticed burnt oil in the V of the engine block as well. To my suprise, same part has failed already. Parts failing at this low of mileage are a design flaw that is being ignored by fca. Something needs to be done. Oh... one last thing..while the mechanic had it apart, he noticed the head gasket was leaking too so he replaced that at 29K miles. No wonder Chrysler/Fiat is the worst car maker in the world.

After driving for about 20 mins the radiator fan would run at full speed to cool the engine. Took it to the shop 12/31/2019 and the diagnosis was that the radiator was leaking with no warning. The service advisor claimed that running the heat too high inside the vehicle probably caused the radiator to crack and leak... the vehicle only had 40K miles on it when the radiator was replaced and was not covered under factory warranty.

- Spring Hill, TN, USA

Have had to have most if not all front of vehicle replaced with ball joints and upper right axle the latest. Now I have a deca code 0198 for several months and now the vehicle is running hot.

- Grenada, MS, USA

I had the check engine light come on and it was reading a P0302 code. This code is associated with the "pentastar tick". I knew that this meant that the cylinder head may be cracked as there are many Jeep owners that have had the same issue. I took it to the dealer ship and they confirmed that the cylinder head was defective.

When starting car -especially in cold weather-and backing out of parking area engine will stall/jar and at times die out requiring putting into park and restarting. Concern is if this happens in traffic it will cause an accident not being moved fast enough. There is a warranty on the vehicle and this has been an ongoing issue for 6mo + and is continuously questioned and evaluated. We've been told it has occurred in other Jeep and there is a fix but this has yet to be corrected for this vehicle.

I replaced a single roller rocker on the right side of the engine early in 2019. Now I am looking at a failed roller rocker on the same side of the engine and potentially an engine replacement.
