While driving at highway speed, the vehicle suddenly lost power, displayed a low oil pressure warning, and became inoperable. The vehicle had to be towed. Dealer initially claimed “overfilled oil,” but an independent oil analysis (Blackstone Labs) confirmed excessive fuel dilution (5.5%), indicating contamination of the oil system. This vehicle is covered by NHTSA Recalls 22V-406 (FCA Z46) and 23V-263 (FCA 01A) related to premature failure of the Bosch CP4 high-pressure fuel pump. Recall documents state: “A HPFP failure may introduce internally failed component debris into the fuel system potentially causing fuel starvation. Fuel starvation may result in an unexpected loss of motive power, which can cause a vehicle to crash without prior warning.” The vehicle’s failure aligns with this description. Dealer has not yet performed an HPFP inspection despite recall requirements. Request: NHTSA investigate whether fuel dilution and catastrophic failure are linked to the CP4 HPFP defect covered by...

I have owned this vehicle for 9 years and the vehicle has had an issue with the electronic fuel pump since I bought it. I would take pictures of the warning showing the error message. I have had the vehicle in the shop more than 10 times for the same symptoms and begged them to replace what the computer is saying was the problem. I have spent over $9,000 on repairs and I continue to get the same message, The check engine light is on continuously and every time I bring it in they say it is not that it is something else and they replace something not related. Then the recall came out for the High Pressure Fuel Pump which was apparently the issue for the entire time like the on board computer had been stating was the issue. I have replaced the Thermostat when there was no over...

My 2015 Jeep Grand Cherokee Overland EcoDiesel (VIN# [XXX] ) had a catastrophic engine failure at 96k miles (400 miles from home) on a family trip Friday [XXX] leaving us stranded far from home for the second time in the last year (first time was for a turbo coolant line that failed requiring me to leave my car in California for 3+ weeks while parts were on back order). I still have an active AEM Warranty from the emissions recalls a few years back that's good until 120k miles, however previous inquiries have stated that this warranty doesn't cover the engine failure and was given a repair estimate in excess of $30k+. Premature engine failures have been a very common problem of this series of vehicle, it was involved in the AEM class-action lawsuit, and had numerous recalls that are related to the engine and engine components. Myself and the...

While driving on the freeway, I heard a quiet noise but saw no warning messages on the dash. I decided to pull over and found the vehicle had shifted into neutral and lost power steering. The vehicle was towed to a AAA service center. They discovered that the safety recall W79 / NHTSA 20V-699 Diesel ECR cooler had been replaced but failed again, requiring a complete engine replacement. The recall was repaired in May 2022, and the part failed in July 2024, two months outside the warranty. The dealer where we bought the vehicle and had the recall serviced won't return my calls.

The engine kicks like the injectors are blocked or something. It happens in idle and all speeds, including highway speeds. It is not speed related. However, I am reporting this because it jerks the car at highway speeds and this is dangerous. I have one occurring trouble light regarding the oil pump but it’s not related. Something is troubling this engine like there is debris in the fuel line but all of my recalls have been fulfilled.

I drove out of the dealership and the engine light went back on. Brought the jeep back and was told engine issue wasn’t covered under warranty and repairs would cost $5k.

tone ring issue not resolved

Th cylinder has low compression causing misfire in the vehicle. The misfire can cause the vehicle to lose power. If you lose power on a highway it could cause an accident. This has not happened to me, but I have read the cyinder issue is a common problem with the 2015 jeep grand cherokee Seems like bad parts. A mechanic has ascertained the problem with my vehicle. If this is a common problem why has the manufacturer not fixed the problem and inspected these parts?

Driving on highway 290 West near Waller. At 75mph I attempted to pass slower traffic by accelerating after moving into the farthest left (passing) lane when my Jeep lost power. Had to maneuver while coasting between traffic in lanes (frogger anyone?) to farthest right lane by coasting through to an exit by chance. Would not restart while coasting. Traffic line formed behind me for those also seeking same exit I needed at the last second. I was unable to fully move into shoulder because of debris seen and fear of damage to tires. After coasting to a full stop a quarter mile from Love's Truckstop, put vehicle in park, and was able to restart after hesitation. Engine light on with my reader stating "confirmed" codes P0336, U1401; and a "pending" code of P05ED. Now takes 3-5 seconds to start when used to be "instantly." In a nutshell, this was not...

See attached document for complaint

I have been trying to get this recall fixed for over two years not. I have received over four notices from FCA via US Mail. Each time I go to the dealer, Planet Jeep, in Flagstaff, AZ I am told that there are no parts available and they cannot do anything. The first three times I was told that I would be put on waiting list however when I checked last week they said there is no record of me even commig in for it. I tried to call FCA directly on the phone number listed to call for help with the recall. The FCA rep said all I need to do is go into the dealer to get it fixed. I explained to her the issue and she put me on hold and called dealer directly. The dealer at Planet Jeep stated same thing, there are no parts available...

While returning home from vacation, the high pressure fuel pump on my vehicle failed. This happened while in heavy traffic traveling 70mph on I-95. This incident left myself, my husband, and my four month old infant at the time stranded on the I-95 shoulder in 90 degree heat for three hours. My husband was barely able to maneuver the vehicle to the shoulder after all power was lost and the car was billowing smoke. The problem was confirmed by the dealer. The dealer inspected and replaced the high pressure fuel pump and other fuel system components four months later but failed to inspect other engine components for damage related to the high pressure fuel pump failing.

The oil cooler located on top of the engine intake failed and began leaking oil. The part of the oil cooler that failed was made out of plastic. The top of the engine gets very hot which likely caused the plastic to become brittle and fail. Oil began leaking all over the motor and onto the exhaust pipes. I could smell burning oil and worried it could cause a fire once I realized what was happening. The repair shop said that they fix so many of these and they are not even a dealer, nor could they understand how a recall has not been issued on this item. The component was not inspected by anyone other than the mechanics at the repair shop. The replacement was an aftermarket made out of aluminum and not plastic like the oil cooler that failed. There were no warning lamps indicating there was a...

The driver's side cylinder head failed and engine oil began leaking down the engine and onto the exhaust pipes. The cylinder head was kept by the dealership and is not available for inspection. My safety was put at risk of a vehicle fire from the fresh oil leaking onto the exhaust manifold and piping. I could smell the burning oil and saw it dipping under my vehicle. The dealer did not say that this was a systemic problem, but it is well documented on the internet that this is a common problem from this model (2015) Jeep Grand Cherokee. The component was not inspected by anyone other than the dealership that determined it had to be replaced. The engine light came on letting me know there was an issue with the engine. I brought the vehicle to the dealership within a few days.

The oil filter housing assembly cracked. I noticed oil leaking yet my oil light would never come on . I took it to be looked at and they had to replace the housing component. I was told that this has been a common problem with vehicles and for me to keep all receipts . If I didn’t pay close attention to my vehicle I could have ruined the engine with the amount of oil that I was loosing. Especially since no warning light was being displayed.

FCA has had an open recall (Z46/NHTSA 22V-406) for over 14 months. They are unable to provide necessary parts and as such potentially unsafe vehicles must be driven by owner and these vehicles are unable to be traded/sold due to open safety recall. FCS Recall Assistance and Chrysler Group Customer Care for Jeep have been contacted with no resolution and no anticipated date for resolution.

Loud ticking noise from engine that speeds up upon acceleration. Failing rocker arm causing debris leading to ticking noise. No error codes. Upon personal investigation online, have found "Pentastar Tick" to be a known problem in 2013-2015 Jeep Grand Cherokees on Jeep forums. Problem can lead to misfire while driving, including jerking, damage to cam shaft, as well as engine damage.

Valve lifter failure at 93,000 miles. $2,700 repair. Is apparently a very common problem with the 3.6l Pentastar engine. Adaptive Cruise Control and Forward Collision warning system front sensor failed at 56,000 miles, failed again at 76,000 miles and failed a third time at 95,000 miles. First two failures were replaced under warranty, third failure happened 1 week after warranty expiration from second replacement. Cost is too expensive to repair ($3,000 for new sensor) and requires that safety feature be turned off as sensor will perceive increases in road elevation (hills) as another vehicle and apply the brakes
