2017 Jeep Wrangler Engine Problems

Oil plug in engine gets brittle and fails by cracking. This cause a complete engine failure with only 36k miles on it. Mechanic says this is a known issue. I could not operate the vehichle and broke down without warning. I have a reciept for the nrand new engine.

Vehicle had a DTC P0302 and a misfire at idle. Upon diagnosis cylinder #2 was found to have 80psi compression which is significantly lower than compression in all other cylinders. Cylinder head was found to be bad. This vehicle only has 61,303 miles. There are many owners complaining about the same problem and FCA indicated they fixed the head issues in 2013. They have offered an extended warranty for 2011-2013 vehicle but the issue still exists. The warranty should be expanded to include more year models.

The contact owns a 2017 Jeep Wrangler. The contact stated while attempting to start the vehicle or while driving at various speeds, the check engine warning light illuminated. The contact stated that the failure had occurred on several occasions. A dealer was contacted. The vehicle was taken to an independent mechanic where it was diagnosed and determined that the valves and the engine needed to be replaced. The vehicle was repaired. The manufacturer was notified of the failure and informed the contact that the engine was not under warranty. The manufacturer offered no assistance. The contact was referred to the NHTSA Hotline for assistance. The failure mileage was 47,000.

The contact owns a 2017 Jeep Wrangler. The contact stated that while driving 45 MPH, the vehicle started to lose motive power. The oil change soon warning light was illuminated. The vehicle was taken to an independent mechanic, and the independent mechanic informed the contact that the oil and coolant needed to be replaced or could cause damage to the engine. The independent mechanic informed the contact that he had experienced the failure with his vehicle due to the failure. The vehicle was then taken to a dealer however, the vehicle was not diagnosed or repaired. The manufacturer was made aware of the failure and offered the contact an extended satisfaction warranty.

The oil cooler leaks and the oil runs down the intake valley, down the back of the engine, and onto the frame and the exhaust pipe, this can create a fire hazard under the driver's seat. It also causes oil puddles on the ground which is a hazard. The dealer says oil cooler leaks are the most common issues on the Chrysler/Jeep 3.6L engine. I was told by the dealer, when making an appointment for replacement, that they have to change these oil coolers a ridiculous number of times. I can safely assume that thousands of people are having this same issue, by the amount of blogs, videos and beware when buying warnings and the fact that there are hundreds of aftermarket options for this item. This leak is going to cost me $1,000 to have fixed because they did not engineer it properly, not to mention cleaning the undercarriage and my driveway. Send me a rebate to cover my cost on this flawed engineering issue please!

While driving in city or highway the engine will shut off randomly, causing the steering almost impossible to turn. Had a few close calls because of this. There is no check engine light to come on.

The contact owns a 2017 Jeep Wrangler. The contact stated while driving at an undisclosed speed, he heard an abnormal ticking sound emanating from the engine compartment, after which the vehicle lost significant motive power. The contact was able to pull to the shoulder of the roadway. After a visual inspection, the contact observed an oil leak underneath the engine compartment. The check engine warning light was illuminated. The vehicle was towed to an independent mechanic, who diagnosed a failure with the piston in cylinder #3. The vehicle was not repaired. The manufacturer was notified of the failure but provided no assistance. The failure mileage was 52,000.

Oil filter housing cracked

Vehicle started leaking a substantial amount of oil. I took it to a mechanic to have it diagnosed, they stated that the engine oil cooler filter housing is made of plastic and over time warps and leaks. Apparently this is a major issue and has been noted on MANY dodge/jeep vehicles. Prior to this happening, the check engine light came on, I had it diagnosed and it showed as a cylinder 6 misfire. This could have caused major issues in the future if it had not been caught when it was including damage to the bearings and the cylinders (probably what is causing the misfire now).

The contact owns a 2017 Jeep Wrangler. The contact stated while attempting to start the vehicle, the vehicle failed to start. The contact stated that the failure had been reoccurring for the past two months. The contact stated that the vehicle was able to be started 50 percent of the time. The vehicle was taken to an independent mechanic and diagnosed with a failed ECM. The contact was informed that the ECM needed to be replaced. The contact was informed of an unknown recall for the 2017-2018 Jeep Wrangler however, the VIN was not included in the recall. The vehicle was not repaired. The manufacturer was made aware of the failure. The failure mileage was approximately 33,000.

The oil cooler leaks when cold and the oil runs down the intake valley, down the back of the engine, and onto the exhaust pipe, which makes it a fire hazard. It also causes oil puddles on the ground which is a hazard when the oil drips splatter other vehicles windshields, as well as making areas slippery for walking. The dealer says oil cooler leaks are very common on the Chrysler/Jeep 3.6L engine. I was told by the dealer, when making an appointment for replacement, that they have to change these oil coolers all the time. Thousands of people have this same issue and there are hundreds of aftermarket options. This leak is going to cost me $1,000 to have fixed because they did not engineer it properly.

The contact owns a 2017 Jeep Wrangler. The contact stated that while the vehicle was parked, he became aware of an oil leak underneath the vehicle. The contact stated that the failure had persisted. The dealer was notified of the failure and an appointment was scheduled for a diagnostic test. The vehicle was not diagnosed or repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 31,000.

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.

Check engine light flashing then steady all of a sudden. Oil leaks

Transmission went out at 86k miles, all maintenance has been kept up with. Jeep broke down while driving, pouring transmission fluid in road, losing all power and unable to go forward or reverse. Problem has been confirmed by service center. Jeep has not yet been inspected by manufacturer, no warnings at all.

The oil filter housing on this engine is made out of plastic and if you search online you will notice that it has failed for many many people. The housing cracks causing motor oil and coolant to mix and leak. We were fortunate to notice it before our engine seized up, but others have not been as fortunate. I believe this defect should be a recall, but there is no recall on this engine even though many many people have experienced this part failing prematurely. Ours failed when the Jeep was under 80,000 miles.

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.

Liquid oil, apparent is oil cooler assembly

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

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.
