Jeep Wrangler oil consumption problems

Filed Oct 14, 2026 · Engine · 111,000 miles · PA

The contact owns a 2016 Jeep Wrangler. The contact stated that the factory oil filler adapter housing was made of plastic, which heated up, warped, and cracked over time. This structural failure caused engine oil to drip and spray across the entire underside of the vehicle, heavily coating the frame and the hot exhaust system. Due to the oil contacting the hot exhaust, a strong burning oil odor entered the vehicle cabin. The contact explicitly stated that their life was in danger due to the continuous failure. The contact stated that the manufacturer was fully aware of the common safety defect. The vehicle was taken to an authorized dealer, where a diagnostic inspection confirmed a complete failure of the oil filter adapter housing. The failure mileage was 111,000.

The vehicle is a 2018 Jeep Wrangler with a 3.6L engine and approximately 124,000 miles. The engine has experienced a failure involving multiple components, including suspected head gasket failure, significant oil loss with no visible external leak, low oil pressure, and engine knocking. Diagnostic trouble codes P0365 and P06DD were present, indicating camshaft position sensor issues and oil pressure control failure. The vehicle is available for inspection upon request. This condition creates a safety risk due to the potential for sudden engine failure and loss of power while driving, which could occur without warning and increase the risk of an accident. The problem has been confirmed by an independent repair facility, which identified low oil levels, coolant loss, and symptoms consistent with internal engine damage. The vehicle has not been inspected by the manufacturer. Prior to the failure, warning signs included a low oil pressure condition and engine performance changes. These symptoms developed rapidly over a short period of time. The vehicle is currently not safe to operate due to the risk of further engine damage or sudden failure.

Since I leased the car, I have taken it to the dealers 4 different times for the steering wheel shaking out of control the first time the "fixed" it but turned me away the 2nd and 3rd time. Each time I requested the left mid speaker to be checked and replaced but they refused to do anything about it until my last oil change 2 months ago. Last year around November they fixed and oil leak, but the cat never leaked oil form the bottom. The Jeep was burning oil not leaking oil and they never did a consumption test. I took it in because the oil levels were low. However, the speaker is still broken, and I did not return the Jeep because they would not give me a loaner car for the service even though it's under warranty. In addition, right front and back tires blew out and when I had the Jeep towed to the dealership for repairs, I noticed that the back tank next to the muffler was leaking. While the Jeep was at the dealership waiting to be serviced, it was vandalized with the rear left window busted out and pain job damaged. My personal registration and insurance information among other things was taken as well. It's been 3 and a half weeks, and they are jerking me around about the repairs. Yesterday, I talked to the service manager (Jose & Rob) they were very condescending about having the repairs done. Upon talking to them I was told that the found and fixed another 'oil leak" but never did a consumption test. I didn't notice the oil being low when I turned in the Jeep on 4/14/25, so they assumed that the leak that I mention was coming from the engine and not the rear and found another leak but had not checked the rear for the leak that I requested them to check. In addition, they claimed that they fixed the oil "leak" without doing a consumption test. I turned the Jeep in on 4/14/25 and the vandalism happened on 4/24/25. FYI this site won't allow me to download the videos of the Jeep doing the "death wabble (shake)". Please email me so I can forward that to you.

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!

The radiator is poorly built and leaks, I have had mine replace several times by the dealership This is dangerous because it causes overheating in the engine which can cause hose to bust and engine to seize up . The oil filter house is engineered incorrect and all of them have been breaking causing oil to leak which again, ruins other components in the engine because of loss of oil. Its dangerous because the oil that leaks down through the outer portion of the engine, through to the sides and leaks over the bottom of the transmission onto the ground which is: 1. Environmental hazard- oil leaking causes water pollution, soil contamination, harm to animals and plants 2. Leaking oil is a FIRE HAZARD and safety issues for other vehicles causing slippery conditions for other vehicles 3. Causes engine damage and eventually failure I urge you to obtain the records of all the repairs jeep dealers did both under warranty and past the warranty dates. Your team will see what an issue this is and the 10000000s of Jeep Wranglers that have had these unsafe problems with the OIL Filter Housing and Radiator issues during and after the warranty. Jeep / Chrysler have created a deceptive way for revenue by allowing Jeep dealers to charge the customers for faulty engineering so they can gain profits in repairs that is the Manufacturer's own fault thereby gouging Jeep Wrangler owners.

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 Jeep oil cooler will leak from factory. It will cause the engine to cease working causing the vehicle to stop. The dealer said this would happen. There were no warning signs, just the smell of burning oil.

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.
