Engine

128 reports1 crash16 fires
“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…”

Service brakes

“Both ORC module and ABS modules have failed on a 10 year old vehicle. Separate issues that greatly impact the cars safety and Stellantis refuses to anything about it to fix issues that can hurt americans. Both modules unresponsive through testing and causing critical safety systems to be inoperable.”

“Abs module has been bad now for over 1 years, I was 541 on waiting list with only 2 available nationwide, now still being told not available and "it's okay to drive without it" by the dealership, so no anti lock brakes, no cruise control, no traction control, this module is now over 1400 dollars to install but not available, hmmm part was 200 bucks before all the 2015 jeep wranglers start to experience the same issue and MOPAR wont make the part , it should be a recall before a driver or other road users get KILLED, this is being reported all over the USA, seems like all 2015 modules are the problem, (should have recalled the plastic abs oil cooler that is placed inside of engine block PLASTIC doesn't withstand heat, but I repaired that to a tune of 1800 bucks) then ABS module out jeep dealer put me on the list for part but not able to say if ever the module will be available, I checked Amazon they have them but was instructed not to use the product on my jeep that it would hurt other components on vehicle, PLEASE MAKE MOPAR make and install these faulty abs module, don't let them force the public to drive without safety features mandated in 2012 on all…”

Power train

51 reports1 crash1 fire
“The contact owns a 2015 Jeep Wrangler. The contact stated that while driving at an undisclosed speed, the vehicle failed to accelerate into a higher gear and went into LIMP Mode. The ABS warning light was illuminated on the instrument panel and was also illuminated prior to the failure. The vehicle was driven back to the residence. A few days later, the vehicle operated normally, but the failure recurred after being driven several times. The vehicle was then taken to a dealer, where a technician diagnosed the vehicle's ABS module failure. The contact was informed that the ABS module needed to be replaced. The vehicle was repaired out of pocket. The manufacturer was notified of the failure. The failure mileage was 81,000.”

Vehicle speed control

32 reports1 crash
“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.”
