2016 Jeep Wrangler Engine problems

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...

My 2016 Jeep Wrangler will buck and jerk when on the highway. I'll be going a steady speed, not changing speed. I feel the car slow down and stomp on the gas but it goes all the way to the floor and nothing happens. When I try to go into the break down lane, the steering wheel locks up and won't turn. Usually I take the key out then put it back in the ignition and it starts no problem. Recently, the engine has been stalling when I put the key back in the ignition. I usually have to take the key out and sit on the...

Anti-Lock Brake System stopped working rendering the car inoperable. The first incident: about 5 years ago the ABS engaged the brakes while driving almost causing a collision. This incident occurred in Guaynabo, PR. After this incident the ABS Module stopped working but the car was still operable. A week ago the PCM lost communication with the ABS module bringing the car into "limp mode" (stuck in 3rd gear until y did not longer engaged the transmission. Also the speedometer stopped working.) This happened while...

While driving my vehicle on Monday, February 16, 2026 I heard a loud pop come from the front of the vehicle. Right after that smoke began to come through the hood vents. I stopped the vehicle to inspect and at that point the engine compartment was burning heavily. I could barely get out of the vehicle and away before the whole front end of the vehicle was engulfed with fire and heavy black smoke. It looked as if the fire started somewhere on the righthand side of the engine compartment because the right front tire...

My vehicle would not start, leaving me in the freezing cold after a 10 hour shift at work. After having the vehicle towed to a service center & a week of inspection, I was notified that the engine had siezed up & needed replaced. The engine oil, front & rear differential, & transfer case fluids had just been changed a week prior. There was no engine warning light prior to this event.

I recently had my oil changed about 3 weeks ago from today. Three (3) days ago, while I was driving, my engine lamp came on and my engine began to run hot. I didn't understand why given that I had just got the oil changed. I pulled to the side of the road and turned the car off to allow it to cool down. It would not crank and I had to have it towed to the auto shop to be serviced which is where they told me that the engine needed replacement.

Vehicle cel for misfire. Replace plugs and coils. Still happens. Dealership says it needs a new engine? My research shows that this is an extremely common problem with Jeep engines. I am aware of a class action suit regarding this issue. I'm not sure of the status. Vehicle has just under 129k miles and is therefore out of warranty. Jeep/FCA knew these engines had problems and continued to sell them without disclosing the highly likely problems ownere would encounter.

On multiple occasions, while operating my vehicle on the freeway, I have encountered a highly alarming problem. The engine of my car has unexpectedly shut off, resulting in a sudden loss of power and control. This has happened when driving between 45-75mph. This has placed me and other road users in extremely dangerous situations, as it has occurred at high speeds where maneuvering and reacting swiftly are essential. I have taken immediate action to have the issue investigated and resolved by authorized service...

As I drive, the car loses the ability to accelerate. It then passively stalls and the automatic steering locks up. All electrical inside the car still stays on. I put the car in park and it restarts on the first key turn. It has happened up to 3 times in a trip, but it is inconsistent when it happens (not necessarily every trip and not at specific speeds (it happeneded going 70 on the highway as well as going 25 in a neighborhood)). When I brought it to the dealership. I was told unless they could make it...

Internal manual transmission problem. Cannot put jeep in 3rd gear. Burning smell

Did not fix problem and now are disassembling engine. Read many other customers with same problem, class action law suit in progress. Manufacturer knows about problem but will not tell owners.

Engine has failed. Had it inspected by two mechanics and they said the same thing, there are broken internal components possibly due to defective components.
