I purchased this 2018 Jeep Wrangler JK Unlimited on July 19, 2025. Since purchasing the vehicle, I have experienced repeated mechanical failures that have required multiple repairs. The most serious issue involves the engine overheating at highway speeds without any visible coolant leak or clearly identifiable cause.Despite seeking professional diagnosis, the source of the overheating could not be determined. Shortly afterward, the vehicle developed a P0302 (Cylinder 2 Misfire), raising concerns about possible internal engine damage caused by the overheating.I believe this presents a significant safety hazard. An engine that overheats unexpectedly while driving at highway speeds can lose power or fail without warning, creating a dangerous situation for the driver and surrounding traffic. The vehicle has become unreliable and unsafe to operate because I cannot predict when it may overheat or experience another engine failure.As someone who often drives alone, I no longer feel safe taking this vehicle on long trips. I am concerned that the vehicle could leave me stranded on a highway or in a remote location without warning, placing my personal safety at risk. A vehicle should provide dependable transportation, not expose its occupants to the possibility of sudden mechanical failure.This vehicle has spent more time in repair facilities than on the road. I have incurred thousands of dollars in repair expenses, and I am now being asked to pay for an engine teardown simply to determine the cause of the failure before any warranty consideration can be made. Despite multiple repair attempts, the underlying cause of the overheating and engine problems has not been resolved.I am submitting this complaint because I believe the repeated overheating, unexplained engine malfunction, and resulting cylinder misfire may indicate a safety-related defect that warrants investigation. I request that the review to determine whether similar failure whether a broader safety issu

The contact owns a 2018 Jeep Wrangler. The contact stated that while driving at an undisclosed speed, the steering wheel seized and the vehicle failed to accelerate. The electronic parking brake, check engine, and several other unknown warning lights were illuminated. The contact shifted to park (P) and then drive (D) and was able to continue driving. The vehicle was taken to the dealer, who was unable to duplicate the failure. The vehicle was taken to an independent mechanic, who determined that coolant had leaked into the computer and damaged the battery pack control module. The mechanic related the failure to Customer Satisfaction Program: Y40 (Control Module Software Updates); however, the VIN was not included. The vehicle was then towed to an unknown dealer; however, the vehicle was not yet diagnosed or repaired. The manufacturer was made aware of the failure. The failure mileage was approximately 100,000.

I bought this vehicle used in 2022 from CarMax. According to Jeep (Stellantis) Co. multiple recalls were fixed by the previous owner, but the patch available for 2018 Jeep Wranglers was not done. In 2024 my iphone and Mac laptop were hacked and shortly after I began having problems with my 2018 Jeep Wrangler. My alarm system started going off while I was in my home without touching or being near the FOB. When I used my FOB to unlock the doors, they would lock back before I could open the door. I was unable to use the push button start for a few minutes up to 15 minutes and in 2025 I was unable to use the push button at all on most days. I had to research a work around to be able to start my Jeep and even after that depending on the day, it takes several seconds to minutes to start it this way. On 2 different occasions as I was driving, I had no control over my steering for approx. 10 seconds. I held on to the wheel and slowed down. The control returned and I was able to drive home. I researched and found out that 2014-2018 had reports of hacking and the hacker taking control of the vehicle in multiple ways including steering, brakes, alarm system, and hacking FOB. My radio has been turned off and the stations changed. One of my FOBs was tampered with, including switching the lock and unlock button's capability, panic button was disabled, and now the FOB does not work at all. There is a loud grinding noise behind my glove box that can be heard at different times including when Jeep is turned off. Loud noises that sound like a rock hitting the window happen randomly to my front windshield, driver and passenger windows happens multiple times while I am driving and when vehicle is turned off. I took Jeep to a trusted mechanic and was told there was no way to tell and it would be better to just sell it. After I moved, I didn't experience these problems for a while, but am experiencing them again. I am concerned for my safety and anyone who may be a passenger in my Jeep.

Oil cooler failure at 7 years and 90000 miles. This is a known engineering issue due to a plastic housing that is resolved by upgrading the oil cooler housing to aluminum instead of plastic. It’s a $1000 repair. Because this is an engineering issue the consumer should not have to pay the entire cost of the repair. This is a SAFETY AND ENVIRONMENTAL HAZARD DUE TO THE LEAKAGE OF OIL CAUSED BY THIS FAILURE. It should definitely be deemed a recall and fixed at the expense of the manufacturer!

I have a 2018 Jeep Wrangler JL Sport S (2 door) with approximately 66,000 miles. On March 26th, 2026 I had a flashing check engine light come up along with the vehicle shaking in low gears. I had the vehicle towed to the Jeep dealership (Gandrud Auto Group) from which I bought it from and upon their inspection they found the left bank head gasket leaking coolant into the combustion chamber causing misfires. This repair was over $5000 and took over a week to fix. The service ticket from Grandrud will be attached which lists all parts that needed to be replaced. This vehicle is much too new to be having these kinds of issues and Gandrud even stated that many customers with JL Wranglers have been coming to them with the same issue of the head gasket failing. 1. Left bank head gasket leaking coolant into the combustion chamber causing misfires. Photos will be attached. 2. Shaking vehicle. Had vehicle towed. 3. Dealership inspected and identified the issue. Invoice attached. 4. Check engine light came on for just one day back in December of 2025, was brought into Gandrud and it was a misfire code, no noticeable issues at the time however and check engine light went away. On March 26th, 2026 I had a flashing check engine light come up along with the vehicle shaking in low gears.

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.

Vehicle equipped with a 3.6L Pentastar V6 engine developed loud ticking noises, engine misfires, and loss of power while driving. The vehicle hesitated during acceleration and could not reliably maintain speed, creating a safety risk in traffic. An authorized dealership pulled diagnostic trouble codes, acknowledged the abnormal ticking, and advised the failure was likely related to the camshaft, lifters, and rocker arms. The vehicle was then taken to an independent mechanic for further inspection. The independent mechanic confirmed failure of the valve train and camshaft components, requiring replacement of the passenger side intake camshaft (Bank 2), cam phaser, phaser bolt, and all lifters and rocker arms. Photos of the failed components are available. The defect was confirmed by both a dealership and an independent repair facility. Issue presents risk of sudden loss of power while the vehicle is in motion.

On January 14, 2026, my 2018 Jeep Wrangler JK Sport (3.6L) with approximately 134,099 miles was inspected at Cox’s Automotive & Repair Inc. due to a check engine light and rough engine operation. During diagnostic testing, multiple fault codes were identified, including P000A (camshaft position slow response), P0300 In addition to the diagnostic findings, I contacted and visited multiple automotive repair facilities regarding this issue. Each shop advised that they have previously serviced 2018 Jeep Wrangler JK models with the same 3.6L engine presenting identical symptoms and diagnostic codes, including timing correlation errors, misfires, and internal engine damage. Several repair facilities indicated that they have had the same make and model in their shops for the same failure, including vehicles with significantly lower mileage, with one reported case occurring at approximately 7,000 miles. Based on consistent feedback from multiple independent repair facilities, this condition appears to be a known and recurring mechanical issue associated with this vehicle model, rather than damage caused by misuse, neglect, or owner fault. (random/multiple cylinder misfires), P0017 and P0019 (camshaft/crankshaft timing correlation errors). Upon removal of the oil filter, metal debris was found in the oil filter cartridge, indicating possible internal engine damage. Based on these findings, the repair facility recommended engine replacement or major engine repair.

On August 6, 2025, while driving at approximately 65 mph on the highway, the vehicle experienced a sudden and total loss of motive power. The engine warning lights illuminated, and the vehicle would not accelerate, forcing an emergency maneuver across multiple lanes of traffic to reach the shoulder. This failure occurred just one day after a warranty repair for the same issue, and followed a previous 199-day repair for a known camshaft defect. This sudden power loss in highway traffic created an extreme and unreasonable risk of a high-speed collision and serious injury.

My Jeep began misfiring, giving a P0304 error code via the ODB. On June 2nd 2025, we took it to the Sandy Sansing CDJR Dealership. They determined that my 3.6L Pentastar V6 engine needed a new camshaft and lifters, despite having only 42,609 miles on it. To further complicate things, it took the dealership over a month to get a replacement camshaft in and installed, due to an abnormally high demand for replacement camshafts; this suggests a systemic problem with the engine, especially considering the problematic history of earlier versions of the 3.6L Pentastar V6 (1). https://static.nhtsa.gov/odi/tsbs/2014/MC-10069161-0335.pdf

The Check Engine light illuminated and diagnostic code P219A was recorded (Bank 1 Air/Fuel Ratio Imbalance), and the engine has a ticking noise. The dealership has indicated the issue likely involves the valvetrain/rocker arms/lifters and will require engine internal repair (valve cover removal, spark plug replacement, possible rocker arm replacement) estimated at ~$2,900-$4,500. The 3.6 L Pentastar engine has been the subject of numerous owner complaints of ticking noise, power loss, misfire, and premature valvetrain failure. I understand there have been related Jeep Technical Service Bulletins (such as 09-002-14 and 09-008-18) addressing these types of failures. A class action lawsuit (Maugain et al. v. FCA US LLC) alleges defects in the 3.6L Pentastar engine’s valve train (rocker arms, lifters) and failure to disclose the defect. Maintenance History: Regular oil changes (every <6,000 miles) at approved service centers; no prior major engine internal repairs. Concern: The defect affects engine performance, may lead to catastrophic engine failure, and potentially reduces safe vehicle operation and control (power loss, hesitation). Relief Sought: I request the NHTSA open a vehicle safety defect investigation and compel FCA / Chrysler / Jeep to evaluate this condition under recall criteria.
