2015 Jeep Cherokee engine problems

“I have a complaint concerning the 3.2L V6 Pentastar engine. A repair was necessary for a manufacturer KNOWN fault concerning factory installation using improperly hardened steel for the Rocker arms/lifters needle bearings, AKA, “The Pentastar Tick”. Rocker arms collapse and cause gouging/scoring damage to the intake camshafts. I had to pay for repairs totaling $5091.05 for this manufacturer’s known and acknowledged, factory mistake. -Copy of final invoice attached.. I have tried to get help from Jeep/Stellantis and assistance to make these expensive repairs. I was told no assistance was possible even though the factory recognized the steel used for the needle bearings that held the rocker arm did not meet strength requirements. Chrysler/Stellantis upgraded needle bearings using properly hardened steel to resolve their factory installation error. I believe Chrysler/Stellantis owes me compensation for costs associated with this repair.”

“The Vehicle suddenly stopped and I was unable to brake or steer the wheel while driving (loss of power/limp mode). I took it to a shop who ran a diagnostic and it came back as DTC code. I now had to tow it out of pocket to the nearest dealership.”

“The car has been suddenly lurching backward and forward in traffic/ while driving, moving forward and backwards unexpectantly and not accelerating at an expected rate, causing other vehicles almost to hit me about 4 times within 1 week starting last week around 12/8/25, because my vehicle is not moving at the expected rate during yielding, changing lanes, etc. I took it to the shop and reported this issue, and they informed me that this vehicle has serious oil leaks and multiple parts that have failed involving the oil filter housing, engine valve cover, engine intake manifold gasket, etc. I have attached a list of parts that have failed in this vehicle from the repair shop for your records and can make available the parts upon request. My repair shop has told me that they have had to repair MULTIPLE other cars of this make and model for the same reason/ failed parts across multiple years up to until about 2021, but that the company repaired it on more current models, which clearly indicates that this is a KNOWN issue for prior models. This company has an obligation to protect its customers and conduct a full recall on prior models to correct this issue, in…”

“My Jeep is disabled due to a drivetrain failure covered under Jeep’s XJ1 Warranty Extension. The required part is on extended backorder (weeks) and Jeep is unable to provide a remedy or transportation while the vehicle is inoperable. This results in a safety hazard and unreasonable delay of repair. Power Transfer Unit (PTU) failure under warranty extension XJ1. Vehicle is disabled and cannot be safely driven. Jeep is unable to provide the part required for repair, resulting in an unreasonable delay of remedy.”

“4wd overheating. Owned this Jeep for 8 years and had it in multiple (5x plus) times for service 4wd code. 2 different dealerships cannot fix the issue. Now they are telling me just drive it and not worry about it or trade it in. It smells hot and something burning. I have the life time max care warranty on it. The codes I get are the 4wd is unavailable overheated and service 4wd. They have replaced multiple parts and still not working. I will be just sitting idle and it comes on.”

“Check engine light on 2015 Jeep Cherokee Sport turned on, vehicle "went limp". Pulled over, turned car off, waited, turned car back on. Happened again taking car to dealership. The dealership said "code for trans range sensor p1726. reset trans and test drove. code did not come back". Same thing happened again a week later. Took it to Firestone, code was "TCM P1726-00 Transmission Manage Sensor "C" circuit High. They said it sounded like the Recall Number 16V529000/S55. I took it back to the dealership, they said the recall, despite being for a 2015 Jeep Cherokee didn't apply and noted "Same code P1726 set in TCM. Going to need range sensor and TCM replaced."”
