2016 Jeep Wrangler engine 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.

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 side of the highway for 5 minutes before starting it up with no problem. This has happened too many times than I’d like to admit. Take it to the shop, no codes come up. Sometimes the engine light will turn on when this happens, other times it doesn’t.

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 driving on a Sunday on busy road. This has been a common issue with Jeep Wranglers made from 2012 to 2018. The company at this moment is not producing replacement parts (ABS Modules) for these vehicles leaving owners without any way to fix or use their cars. ABS Module DTC's: -C2200 -U0100 -U0141 -U0126 -U0002 While scanning the module comes and goes offline.

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 was the first to blow out in the fire. The vehicle is with the insurance company to inspect, but it was in perfect running condition, all maintenance performed. There were no dash warning lights that came on, no odd sounds heard and the vehicle ran until I stopped and shut it office. There has to be something that was wrong with the manufacturing of this specific engine to make a loud pop and burn as hot as it did. I wanted to report this before the vehicle is sent away to be demolished due to it being a complete loss.

Head gasket failure, causing motor to overheat.

Unsafe Vehicle, Unresolved Mechanical Failures – Serious Safety Concern On [XXX], I purchased a Jeep (VIN: [XXX] ) from Whipple Auto Sales. Since the purchase, the vehicle has experienced repeated mechanical failures that have created serious safety concerns. Approximately two weeks after purchase, the dealership replaced a fuel injector due to performance issues. About one month later, the vehicle began showing sensor codes and experienced sudden power loss while driving. On [XXX] the vehicle completely shut off while I was traveling on the highway, placing my safety at significant risk. The dealership initially stated that the key required reprogramming. However, after keeping the vehicle for approximately one month, they were still unable to repair the issue. The dealership later claimed the problem was related to the powertrain. Without resolving the issue or providing proper notice, they returned the vehicle to my residence in worse condition than when it was left with them. At this time, the vehicle is unsafe and unreliable, and I cannot confidently operate it. This situation demonstrates a lack of proper repair, accountability, and resolution. I am extremely concerned about the safety and reliability of this vehicle and the dealership’s handling of this matter. I am seeking a proper resolution to this issue.
