Vehicle has 143,345 and engine started ticking from valvetrain on drivers side. It is a known issue with the 3.6 liter V6. Will probably have to pay out of pocket to have rockers, lifters and camshafts replaced.

3.6L Pentastar engine is defective. In October 2020 (55,000 miles), there was a ticking noise coming from engine and reduced engine power. Fields Jeep Dodge Ram Chrysler replaced right intake camshaft and 6 lifters, rockers, and related gaskets. In April 2021, I noticed same ticking noise; brought back to dealership; dealership found "nothing wrong." In March 2022 (70,000 miles) I heard same ticking noise; brought to dealership; insisted something was wrong. SURPRISE! This time, ALL (12) ENGINE lifters/rockers/gaskets & camshafts replaced. Now, May 2023 (80,000 miles) there is, again, ticking in engine/loss of power; this time there is a noticeable bucking and surging when the engine is cold. There were no warning lights or messages on the dashboard to indicate impending engine failure. Symptoms I experienced were loss of engine power, ticking, and bucking/surging. I WISH someone from NHSTA would come and inspect the car. Safety issues can arise if the engine fails while being driven - increased risk of stalling, loss of motive power, obviously collision, any number of things. On two separate occasions, Jeep dealership identified and "fixed" the issue with the same faulty parts that caused the problem in the first place. Other than the dealership, no one else has inspected the vehicle. This issue is ongoing and will continue to occur as a result of an inherently faulty engine design, for which the only remedy is to fix it with the same defective parts.

The oil cooler located on top of the engine intake failed and began leaking oil. The part of the oil cooler that failed was made out of plastic. The top of the engine gets very hot which likely caused the plastic to become brittle and fail. Oil began leaking all over the motor and onto the exhaust pipes. I could smell burning oil and worried it could cause a fire once I realized what was happening. The repair shop said that they fix so many of these and they are not even a dealer, nor could they understand how a recall has not been issued on this item. The component was not inspected by anyone other than the mechanics at the repair shop. The replacement was an aftermarket made out of aluminum and not plastic like the oil cooler that failed. There were no warning lamps indicating there was a problem. When I saw the oil under my vehicle and the smell of burnt oil on the exhaust pipes I brought the vehicle to the repair shop.

The driver's side cylinder head failed and engine oil began leaking down the engine and onto the exhaust pipes. The cylinder head was kept by the dealership and is not available for inspection. My safety was put at risk of a vehicle fire from the fresh oil leaking onto the exhaust manifold and piping. I could smell the burning oil and saw it dipping under my vehicle. The dealer did not say that this was a systemic problem, but it is well documented on the internet that this is a common problem from this model (2015) Jeep Grand Cherokee. The component was not inspected by anyone other than the dealership that determined it had to be replaced. The engine light came on letting me know there was an issue with the engine. I brought the vehicle to the dealership within a few days.

While driving down the road my car will shift into Neutral while going at at full speed driving down the freeway, and loses all power. I have to pull over on the side of the road turn the car off and restart. This has happened 6 times and is very dangerous. There are multiple dates that this has happened. It looks as though this should fall under NHTSA recall #16V529000?

Feb 2023 Crash

On April 24, 2023, while driving 53 mph down a busy highway the car just lost all power. I wasn’t able to control the vehicle then I stepped on the brakes but only if the back brakes worked. Which caused the vehicle to spin out of control until I eventually flipped the vehicle upside down into a ditch. It was one of the scariest things I’ve ever experienced. Besides the fact my drivers side head rest and seat bell we’re also broken at the time. I was going to the dealership on April 26th to have both the headrest and seat belt fixed. It’s also the second time the car lost power. In addition to that my headlights, rear lights, & windshield wipers, would suddenly stop working then work again. I totaled my Jeep and I’m now out of a vehicle since I had a active loan of the vehicle. I was suppose to be done with my payments in Aug of 2025. I don’t ever want anyone to experience what I went thru. I’m very very grateful and fortunate that I wasn’t seriously injured or killed because of this problem.

Vehicle only has 38,000 miles and suddenly had visible oil leaking from underneath. No warning lights came on but I took to service center for inspection. The oil filter housing was found to be defective and "leaking badly". Technician informed me that because the component is plastic vs. metal it is a known defect in my vehicle make/model. I also confirmed many complaints of same issue in online forums. I contacted manufacturer but since vehicle is out of warranty they would not assist. Service provider stated the issue is of significant safety risk as engine could lose all oil, overheat, and become undriveable. Cost to repair=$1800

The oil filter housing in the Jeep Gladiator, Wrangler, and Grand Cherokee is known to have serious problems and safety concerns. The Pentastar oil filter housing used in these vehicles can crack and warp due to heat exposure and this can lead to serious oil leaks. Despite knowing about this issue, the company has never issued a recall, instead, they have discontinued the production of the Pentastar and redesigned the oil filter housing for newer vehicle models. https://vehiclefreak.com/jeep-oil-filter-housing-recall-guide-2013-to-2017/?fbclid=IwAR372r_Z1vlEwSsMz6HmMA6_Vn1IEqL3SnyNYNGCuCVbH25-F7cUtjkhzpU

Noticed a wet substance under the hood and a smell of oil/antifreeze (couldn’t determine either or) coming from vents prior to purchase. I was told it would be looked at and taken care of. After purchase I noticed a heavy leak under the vehicle and when i touched it, I again smelled the same oil/antifreeze. I took it back to the dealership and they replaced the radiator. It continued to produce a leak, and chose to stop and get a diagnosis and they said it was the oil cooler. I then chose to return it to the dealership for repair and they insist it was left over spillings from the previous repair. It still has that same wet substance dripping from under the vehicle. I’m concerned about the safety of my life if it is indeed the oil cooler.

The oil cooler fails resulting in the entire cooling system being filled with the oil from the engine and possibly contaminating the engine oil with coolant. Even after the oil cooler is replaced the entire cooling system must be thoroughly flushed and have multiple parts replaced. It is a safety hazard because there is no warning, the oil cooler fails and all you engine oil is gone. Which will lead to catastrophic engine failure and possibly fire from the heat produced from the friction.

The oil cooler/ oil filter housing cracked. My 2015 Jeep only has 49,000 miles on it. This is a huge safety problem. The oil leaked all over the transmission case and the exhaust. It was smoking really bad, this is a fire hazard!!! I found out that there has been many complaints on this issue and should be recalled for safety. The dealership told me to have it towed in because you can not drive it because it can catch on fire. Not good, someone can really get hurt!!! Recall this product.

The oil cooler failed with no warning, no check engine indication. All indicators returned normal readings. Without a warning you continue to drive while your oil levels are falling. All of your oil goes into your cooling system. The chances are very high that you will have your engine seize. At a minimum the failure causes major repair issues, if it can be repaired at all. One of the more troubling out come of the failure, the oil will eventually over flow the coolant reservoir into the engine compartment. The oil is everywhere in the engine compartment. This alone would present a number of safety issues. My car is currently at the dealer, I was quoted $8,600 to repair and replace all affected parts. My research has turn up a number of jeep, chrsyler and ram truck owners are or have experienced this failure.
