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.

Engine compartment fire
On October 15, 2015, Fiat Chrysler Automobiles, US LLC, (FCA), submitted a Defect Information Report (DIR) to the federal safety agency regarding an air-conditioning suction/discharge combo line routing condition that may result in engine compartment fire in approximately 75,574 model year (MY) 2015 Jeep Cherokee vehicles equipped with 2.4L engines and built from October 1, 2014 through June 18, 2015 (the federal safety agency Recall 15V‑676, FCA Recall R57).According to FCA's DIR, a misrouted A/C combo line can be pinched and cut or thermally degraded by the exhaust manifold heat shield, potentially resulting in loss of air conditioning, smoke and/or fire from ignition of leaked A/C refrigerant oil onto a hot exhaust manifold.The recalled vehicles will be inspected for misrouted A/C combo lines and those found to be misrouted will be replaced.FCA estimates that one percent of the recalled population may be affected by the A/C combo line routing defect.ODI?s analysis of warranty data provided by FCA in response to the information request letter for PE15-003 identified a spike in claims related to the A/C combo line leakage in vehicles equipped with 2.4L engines built after October 1, 2014.FCA implemented its final process corrective action for the hose routing concern on June 18, 2015.The 113,034 MY 2015 Jeep Cherokee vehicles equipped with 3.2L engines have different A/C line routing configurations and are not affected by the A/C combo line routing defect.FCA provided a total of 220 warranty claims potentially related to the A/C combo line in vehicles equipped with 2.4L engines.Ninety-five percent of the claims (210) involved the 74,574 Jeep Cherokee 2.4L vehicles built during the recall period.Only 10 A/C combo line claims and no related fires were identified in the 28,250 Jeep Cherokee 2.4L vehicles that were built before or after the period with the hose routing concern.Analysis of engine compartment fires reported to ODI and FCA identified a total of 10 fires in MY 2015 Jeep Cherokee vehicles.Nine (9) of the fires involved vehicles equipped with 2.4L engines and 8 of these involved vehicles built during the production range subject to Recall 15V‑676.These include 5 fires that FCA's investigations determined were most likely caused by the A/C combo line and 3 fires of unknown cause originating in the area of the exhaust manifold heat shield, resulting in fire incident rates in the recall population of 6.6 per 100,000 vehicles for the A/C combo line condition and 10.6 per 100,000 vehicles for fire incidents for which the A/C combo line could not be excluded as the cause.The other 2 engine compartment fires involved a low-mileage fire of unknown cause in a vehicle equipped with a 3.2L engine and a minor self-extinguished fire that FCA?s investigation attributed to a lower transmission oil cooler (TOC) line connection seepage condition in a rental vehicle equipped with a 2.4L engine and built prior to the recall production range. This preliminary evaluation is closed based on FCA?s recall.The following VOQ numbers are associated with the issues discussed in this closing resume: A/C combo line failure:10786287 Unknown cause:10712350, 10678215, 10672201

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 order to prevent serious injury or death of the public! I trust you will investigate this matter thoroughly.
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.
The contact owns a 2015 Jeep Cherokee. The contact stated that while driving at 61 MPH and accelerating, the vehicle stalled twice. The contact stated that the cabin was filled with smoke. The contact was able to pull over and open the hood and noticed the smoke near the engine. After 4 minutes, the smoke dissipated. The vehicle would be towed later. The local dealer was contacted, but the vehicle was not diagnosed or repaired. The manufacturer was not contacted. The failure mileage was approximately 162,000.
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."
The vehicle suddenly started showing parking brake, traction, ABS, and check engine lights after being started. Earlier in the day, I had also started the vehicle but cancelled the errands and returned to start it later when the dashboard and warning lights came on. Putting it in reverse, the steering was stiff as if in neutral. Never left the driveway as I wasn't taking a chance in steering or braking. The battery is less than a year old. This is the second time this has happened.
