On April 24, 2023, while driving 53 mph down a busy highway the car just lost all power. I wasn-??t able to control the vehicle then I stepped on the brakes but only if the back brakes worked. Which caused the vehicle to spin out of control until I eventually flipped the vehicle upside down into a ditch. It was one of the scariest things I-??ve ever experienced. Besides the fact my drivers side head rest and seat bell we-??re also broken at the time. I was going to the dealership on April 26th to have both the headrest and seat belt fixed. It-??s also the second time the car lost power. In addition to that my headlights, rear lights, & windshield wipers, would suddenly stop working then work again. I totaled my Jeep and I-??m now out of a vehicle since I had a active loan of the vehicle. I was suppose to be done with my payments in Aug of 2025. I don-??t ever want anyone to experience what I went thru. I-??m very very grateful and fortunate that I wasn-??t seriously injured or killed because of this problem.

We have been unable to drive the vehicle for 9 months out of 12 due to it being in the shop. The latest was a OBDC of "Improper DEF used see dealership". It was at 3 different shops to remedy the issue the final one being Lithia Chrysler/Jeep/Dodge of Missoula #134. Even with the extended warranty they WOULD NOT cover the expense even though it was their warranty. We were told it was for labor, but labor was supposed to be covered. There is also a "Stop Sale" in place so we cannot even drive the vehicle anymore due to lack of power. The dealership and FCA told us that this was "NORMAL" and we just "HAD TO LET THE VEHICLE WARM UP FIRST" I have owned and operated diesel vehicles for a better part of 28 years. I have NEVER had to do this. I cannot put my families lives at risk with this POS. Right now as it is, we are. making payments on insurance and and vehicle payments on an SUV we cannot drive. I can give specific dates, times and conversations as well as email threads from FCA trying to handle the situation to no avail.

While in motion, vehicle lost all power; the engine stalled, brakes failed and lost power steering. The vehicle shifted into neutral. I put the vehicle back in drive and it went back to neutral. I turned the ignition off and restarted. My husband was driving and I was in the passenger seat, with my 5 year old daughter in the backseat. If there had been oncoming traffic, we-??d have hit them head on.

Vehicle only has 38,000 miles and suddenly had visible oil leaking from underneath. No warning lights came on but I took to service center for inspection. The oil filter housing was found to be defective and "leaking badly". Technician informed me that because the component is plastic vs. metal it is a known defect in my vehicle make/model. I also confirmed many complaints of same issue in online forums. I contacted manufacturer but since vehicle is out of warranty they would not assist. Service provider stated the issue is of significant safety risk as engine could lose all oil, overheat, and become undriveable. Cost to repair=$1800

The oil filter housing in the Jeep Gladiator, Wrangler, and Grand Cherokee is known to have serious problems and safety concerns. The Pentastar oil filter housing used in these vehicles can crack and warp due to heat exposure and this can lead to serious oil leaks. Despite knowing about this issue, the company has never issued a recall, instead, they have discontinued the production of the Pentastar and redesigned the oil filter housing for newer vehicle models. https://vehiclefreak.com/jeep-oil-filter-housing-recall-guide-2013-to-2017/?fbclid=IwAR372r_Z1vlEwSsMz6HmMA6_Vn1IEqL3SnyNYNGCuCVbH25-F7cUtjkhzpU

At a speed of 30mph, was slowing down coming up to a red light, as the brakes were being pressed the motor began to rev up and try to accelerate despite me fully pressing the brakes. I had to put the vehicle in neutral and shut it down. I merely missed hitting another vehicle. I called the dealer who had no information for me. No warning lights were on or prior to the reving and acceleration of the vehicle as I was trying to come to a stop at a red light. I am reading numerous forums of Jeep owners reporting the same issue. This really should be investigated before someone is seriously injured or killed, which maybe there have been reports of such already. In my case, there was no injury or damage because I was lucky enough to have no vehicle beside me and had a place to vere off to to pull over quickly. If that hadn-??t been the case, an accident would have occurred. I can-??t say if this vehicle has malfunctioned like this previously because I purchased 2 days ago.

Noticed a wet substance under the hood and a smell of oil/antifreeze (couldn-??t determine either or) coming from vents prior to purchase. I was told it would be looked at and taken care of. After purchase I noticed a heavy leak under the vehicle and when i touched it, I again smelled the same oil/antifreeze. I took it back to the dealership and they replaced the radiator. It continued to produce a leak, and chose to stop and get a diagnosis and they said it was the oil cooler. I then chose to return it to the dealership for repair and they insist it was left over spillings from the previous repair. It still has that same wet substance dripping from under the vehicle. I-??m concerned about the safety of my life if it is indeed the oil cooler.

I have to pull over on the side of the road turn the car off and restart. This has happened 6 times and is very dangerous. There are multiple dates that this has happened.

The oil cooler fails resulting in the entire cooling system being filled with the oil from the engine and possibly contaminating the engine oil with coolant. Even after the oil cooler is replaced the entire cooling system must be thoroughly flushed and have multiple parts replaced. It is a safety hazard because there is no warning, the oil cooler fails and all you engine oil is gone. Which will lead to catastrophic engine failure and possibly fire from the heat produced from the friction.

There is loud ticking/tapping noise coming from the engine when in motion or when the engine idles. This vehicle was not inspected by the dealer (out of warranty) or the police but was inspected by my mechanic and is available for inspection anytime, upon request. At time, the noise become extremely loud and scary and is a cause for great concern, especially knowing that this vehicle is mostly driven daily on the highway for at least 1 hour one way. This noise suddenly appeared about 9 year ago as a slight ticking/tapping but got progressively worse.
