My 2015 Jeep Wrangler has experienced multiple incidents of sudden, unexpected engine shutdown while driving. Without warning, the engine completely loses power, causing the vehicle to lose propulsion and power steering assistance. The dashboard lights and radio remain operational during these incidents. I must turn the ignition off and restart the vehicle, after which the engine starts immediately and operates normally. The vehicle previously experienced similar problems involving additional electrical malfunctions. The fuel pump was subsequently replaced, and the camshafts and rocker arms have also been replaced. Despite these repairs, the engine has unexpectedly shut off approximately two or three additional times. These incidents occur intermittently and without warning, making them difficult to reproduce during dealership inspections. I am concerned that the vehicle could suddenly lose power in heavy traffic or at highway speeds (as it’s done previously even in the pouring rain), potentially resulting in a serious collision. The underlying cause remains undiagnosed and unresolved.

What 2015 Jeep Wrangler owners say
Most recent owner complaints, unedited.
I purchased this 2015 Jeep Wrangler Rubicon new and have maintained and serviced it regularly. At approximately 75,000–80,000 miles, the engine began developing a ticking noise from the passenger/right cylinder head area. The problem progressively worsened. At approximately 100,000 miles, repairs were performed involving the right-side cylinder head and camshaft because of camshaft/valvetrain wear and a persistent cylinder #2 misfire. The right-side cylinder head/camshaft area has required repair more than once. Rocker arms were also replaced, but the underlying problem continued. The vehicle now has approximately 150,000 miles. The engine recently shut down and developed a loud mechanical noise. Upon inspection, significant wear/damage was again found involving the right-side exhaust camshaft/valvetrain, and there are concerns involving the timing chain/tensioning system. A failure of these components while driving could cause sudden engine shutdown or loss of power, creating a safety risk. The vehicle has also developed electrical/safety-related problems. The airbag warning light is illuminated, and the steering-wheel controls and steering-wheel illumination are not functioning. The vehicle was involved in an accident in 2019; however, the engine ticking condition was already present before that accident, although it was less noticeable at that time. Despite previous repairs, the engine/valvetrain problem has returned. I am reporting this because the repeated camshaft/valvetrain failure, persistent cylinder #2 issue, possible timing-system problem, and associated risk of engine shutdown appear abnormal and potentially safety-related for a regularly maintained vehicle.
From September 2024 I have a problem with the engine system make a noise i always make oil change on time and also electric problems and seatbelts problems l know a 2 3 owner off jeep wrangler with the same problem
In October 2025, the Anti-lock Breaking System (ABS) Brake, traction control, downhill control indicators all illuminated. This also impacts cruise control and acceleration from a stopped position. My repair technician placed an order for the necessary ABS control module with MOPAR. The expected delivery date was August 2026. In August 2026, MOPAR informed them the part was on a nationwide back order with no ETR for resolution. I placed an order for the ABS Module in August 2026, with a suggested date of delivery in two weeks. MOPAR has advised us today 18 August 26, there is no ETR for this critical component to be available. Anti-lock brakes are federally mandated in all vehicles 2012 and beyond. Not having this module disables multiple required safety components in the vehicle not just ABS and puts the consumer, other drivers at risk.
Lifters ticking noise causing damage to cam shafts.
am the original owner of this 2015 Jeep Wrangler, which I purchased new. The vehicle has been properly maintained according to the manufacturer's recommended maintenance schedule. I have records documenting routine maintenance, including regular oil changes. At approximately 75,000 miles, I began hearing a persistent ticking noise from the engine. Because I was concerned that the noise could indicate a mechanical problem, I scheduled an inspection with an authorized Jeep dealership. The dealership diagnosed the vehicle with a failed rocker arm that caused damage to the exhaust camshaft. The dealership advised that the intake camshaft remained in good condition, indicating that the failure was isolated to the exhaust valvetrain at the time of diagnosis. This type of internal engine failure at approximately 80,000 miles was unexpected for a properly maintained vehicle. My concern is that if this condition is not diagnosed promptly, continued operation could result in further engine damage, loss of engine performance, engine misfire, or potential engine failure while the vehicle is being driven, creating a potential safety hazard. While researching this issue after receiving the diagnosis, I found numerous reports from other owners of vehicles equipped with the 3.6L Pentastar engine describing similar rocker arm and camshaft failures across Jeep owner forums, Reddit, Facebook owner groups, and YouTube. Although I understand there has not been a recall for this condition on my vehicle, I believe the number of similar owner reports suggests the issue may warrant further review. I am submitting this complaint so that the federal safety agency is aware of the issue and can evaluate whether similar failures are occurring with sufficient frequency to justify additional investigation.
I purchased a used 2015 Jeep Wrangler from a dealership in New York. At the time of sale, the vehicle had an open urgent safety recall (19V‑018) for a defective Takata passenger airbag inflator. This recall was never disclosed to me by the dealership prior to or at the time of purchase. The recall advisory was noted on the NYS inspection report conducted the same morning the vehicle was sold to me, but was not communicated to me in any way. I discovered the open recall after experiencing repeated mechanical failures following purchase. Four days after purchase the vehicle overheated and had to be towed — the coolant system was found to be completely empty. An independent licensed mechanic subsequently inspected the vehicle and stated on record that the mechanical defects appeared to be pre-existing conditions that existed prior to the sale. The vehicle currently has an unrepaired Takata airbag inflator which the manufacturer has identified as capable of exploding and sending metal fragments into the vehicle interior at high speed, risking serious injury or death to occupants. The vehicle is available for inspection upon request. The recall remains unrepaired. The dealership was contacted and a manager verbally acknowledged they did not disclose the known defect prior to sale.
ABS Module error: C2200 causes jeep to go into limp mode when accelerator is pushed hard. near miss on collision, lack of abs causes skidding and possible loss of control.
While driving on the highway, my Jeep completely shut off and I lost control of everything the staring and I have no clue why it just shut off. I’m worried if I drive it I could do this while I’m on the highway and the third lane and I may end up in a collision.
Our 2015 Jeep Wrangler JK Unlimited just caught on fire. I happened to be in my daughter’s bedroom, 20 feet away from where the Jeep was parked. I thought I was seeing flames reflecting from the TV, but I realized that they were real. My next thought was that my husband was building a firepit fire. I thought that was weird because he was doing it in the front yard, but I didn’t think any more about it because I was so focused on my work. I went back to work for a second, but something told me to look again. I did, and then realized that it was the Jeep that was on fire. I screamed for my husband, but couldn’t find him; I was scared that he was in the Jeep. Actually, he had been in the back yard and heard me screaming, so he ran up front to see what was happening. I called 911 while my husband tried to put the fire out with the water hose, which didn’t help- the flames kept getting higher. It took firefighters a while to extinguish the flames and to get it cooled off. The engine appears to be melted. It is in our yard and available for inspection. The fire fighters made a report that my husband has requested. We’re waiting on the insurance company to contact us. The fire smelled electrical. We smelled no gasoline. I was absolutely horrified thinking about what might have happened if it had ignited at night when no one was looking. My daughter, my pets, my husband, and I could have all been casualties of this spontaneous fire. The fact that it was day time, the unusual coincidence that I was where I was so that I saw the fire, and the fact that my husband parked on a different side of the yard than usual, all probably are the reasons we are alive today. Had any one of those events not been in play, it could have been a very different outcome. My husband had no indication that there was a problem with the Jeep. He’d just driven it. He reported no odors and no problems at all. He takes excellent care of it, so it was in great condition.
