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 these recalls.

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 heating issue, the alternator when there was no electrical issue, the Particulate filter because they said that was what was causing it to go into crawl mode which it still does periodically when it rains out. The recall was issued on 6/9/2022 and it is still not repaired. There is no telling what other internal damage was done over the 9 years of not replacing what was the issue the entire time.

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.

Purchased a 2015 jeep grand Cherokee. At around 65k miles vehicle started making a ticking sound. Vehicle was also stalling when accelerating from a stop, usually when making a right turn but also when trying to press gas to gain speed quickly like when entering the highway. There is a known issue with this model where the rocker arm fails and damages the cam shaft. Engine light went on so contacted the dealer and Brought the car in for a recall repair. 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. I’m contacting the DMV automotive facilities inspector to file a complaint on the dealership and will be contacting a lawyer regarding a class action lawsuit unless I get a resolution to this issue. I drive my 3 small children around every day in this car.
