What owners report most
Engine
“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.”
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.”
Electrical system
“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…”
