Jeep caught on fire on the interstate. 17 year old boy had to pull over and escape vehicle. Vehicle left the side of the road even after being in park and brake. Vehicle continued unmanned on interstate into oncoming traffic engulfed in flames. It has not been confirmed by a dealer. Vehicle was inspected by State Farm. NO warnings given prior to incident.

Engine light came on stating cylinder #4 miss fire. After taking it in, the mechanic said that they can repair the head but it will most likely be an issue again in another 30k or it will be another cylinder. They said it is still causing the air to leak. This Jeep only has 51k miles and is in mint condition. After further research, Jeep had previously recalled this same issue on Jeeps a little older than 2017.

I smell oil burning as I drive then found oil on the garage floor. Found the oil adaptor (Oil filter housing) worped causing oil to drip out and onto the hot exhaust. Oil on heat is a safety issue and should be addressed.

My oil filter housing is cracked. I have a 2017 and it is plastic I know after 2017 Jeep knew of the issue and changed the production type then. This is a known issue. Happens to many Jeeps I hear about it a lot. It-€™s a $1000 fix for something that is common in Jeeps and other pentastar 3.6l engines. I am getting it fixed this week for I am getting a kidney transplant and need it done before the surgery.

Oil cooler assembly cracked and warped (also k own as oil filter housing) this led to a large oil leak and depleted all oil from engine. Repair was over $1,000. All mechanics are saying this is a known issue and becomes expensive because both intake manifolds need to be removed to replace

Oil cooler warp/crack because the bottom is made of plastic stored inside engine where extreme heat causes warp/crack on the cooler. Ultimately leaks out oil, causing saftey hazards to the community and owner. A known defect/issue with all penstar engines (other vehicles with this engine are affected). There should be a recall for this issue/defect. I hope NHTSA do a thorough investigation on this issue. Thanks!

Oil cooler housing has serious design flaw. It is made made of plastic and is subject to warp and crack from constant heat exposure leading to failure and catastrophic oil leakage onto hot engine with significant risk of fire as result.

Oil Filter Assembly failure. This issue has been consistent in respective Chrysler engines since 2014 without resolve or re-design. I have been without vehicle since the 24th (today is 3/3) and renting a car out-of-pocket. The parts are backordered as I've been told there are restrictions by Chrysler on these discontinued replacement parts. Repairs cost upwards of $1,000 depending on the dealer and situation (if oil hasn't damaged other surrounding parts). All forums are consistent in that there has been no recourse by any representative from Chrysler or, in my case, Jeep. The anticipated costs in my situation are likely to exceed $2,500 given the schedule of the repair and any secondary damages by the leaking oil.

The Oil Filter Assembly is defective. It leaks oil. Yes it-€™s available for inspection. Oil leaks onto engine and eventually to exhaust system.This will result in smoking and fire. This has been identified by an independent service center and numerous social media sites. Has not been inspected by those listed above. No warning lamps, messages or other symptoms prior to a scheduled oil change wherein the defect was discovered. This first appeared 6 months ago.
