2015 Jeep Cherokee engine problems

ENGINE

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

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.

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.

ENGINE

Electrical system/Transmission malfunctioned causing engine to shift into neutral while driving and cause engine to shut down and refuse to start again. The issue seems to only happen whenever the engine is up to temperature and the fan is active. The vehicle has been inspected by a dealership and they said the throttle body was the issue, after replacement the issue still persists. There is no warning lights or symptoms. It will happen either at rest or in motion. I was driving yesterday and it happened after I had completed a lane change and was almost hit by a semi. This is not the first instance of it occurring.

This vehicle is not safe to drive because it doesn't brake, it takes several seconds to reduce speed after hitting the brakes, and at high speeds it takes longer, which can put anyone's life at risk. The engine is damaged, it releases smoke and is leaking oil, and it heats up when you're moving on the freeway, which can be dangerous. The car loses power while moving. They told me that it was in perfect condition, which they lied to me, putting the lives of many people at risk. The second day after I took it out of the dealership, I realized that the engine was damaged. It started to smoke and lose power. On the road, I almost had an accident because the car didn't brake well. They sold it to me like that. They didn't want to give me the carfax and it hasn't been inspected.

My vehicle - at random - will switch to traction control, 4x4, and will slow down while driving, and will not allow me to go above 45 mph, with the engine rpm’s revved as high as if I’m driving 85 mph. No mechanic has been able to accurately diagnose it, and I continue to pay for different repairs, without getting the problem actually solved.

I was driving down the highway and my car just shut off and came to a complete stop in the middle of the road. It happened twice. Both times the emergency brake light came on but at no time was the emergency brake engaged by me. I was lucky that I wasn’t on a busy road and the care behind me had time to react or it could have been fatal. After trying to restart the car it took some tinkering with the ebrake and after a slight hesitation of the engine, it started. That happened twice in one day and once on another. This is a huge issue that can cause loss of life.
