While driving, engine immediately shuts off. Dash, radio, lights, etc. all function as normal. Dash cluster shows an error message, saying to shift into Park. After parking vehicle on shoulder, engine turns over but does not restart after several attempts. After awhile, engine finally restarts. No error codes or messages are displayed. Scanning with an OBD device shows no stored or pending error codes. Vehicle now operates normally. This has happened twice in the span of two weeks, and never previously.
2015 Jeep Grand Cherokee engine complaints
Page 2 of 9: complaints 11 to 40 of 221, newest first, as owners wrote them.
Despite having the EGR replaced under recall the unit still exploded while driving on wed 4 Mar 2026. Fluids were leaking and had indicated issues with the electric shifter. The local dealerships states the egr cooler needs replaced, coolant tank, DPF and oil change (despite just being done the Saturday before). Refusing to acknowledge any connection to previous recall or associated damages. Contacted FCA customer support and ignored my concerns and said just pay the dealer the $6000+.
Vehicle began displaying check engine light. Diagnostic code P219B (Bank 2 air-fuel ratio imbalance) was identified. Vehicle was serviced and a valve-related repair was performed. Shortly after, engine performance worsened and further inspection revealed metal shavings in engine oil and confirmed internal lifter/valvetrain failure. Oil levels were normal and maintenance records are available. No warning of low oil pressure or overheating occurred prior to failure. Independent service center and inspector confirmed internal mechanical failure. Engine failure created risk of sudden loss of power while driving. This appears consistent with documented Pentastar 3.6L valvetrain/lifter issues reported by other owners. Concern is potential for sudden engine malfunction and safety risk due to power loss.
Had to have repairs done after two weeks of purchase of vehicle for recall for vehicle losing power when picking up speed also engine light is on continuously. Contacted dealer and requested repairs Dealer was non-compliance.I had to pay for repairs myself. Still having issues and engine light still on.

My engine oil is mixing into my coolant jug and radiator replaced the oil cooler housing and the issue still continues
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 the federal safety agency 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: the federal safety agency investigate whether fuel dilution and catastrophic failure are linked to the CP4 HPFP defect covered by these recalls.

Cylinder 2 misfire
I was crossing a road to get to the median and my Jeep stopped moving in the middle of a 4 lane highway, separated by a median that I never made it to due to it stopping moving during acceleration. It made noise when I pressed on the gas pedal but didn’t go anywhere. I was hit by a car that couldn’t avoid me, and my daughter and I were injured in the crash. My daughter had a fracture in her right leg & facial bruising. I had a laceration requiring stitches and facial bruising, lost consciousness at the scene and am severely concussed. Progressive deemed my Jeep a total loss.

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 local dealer was not yet contacted. The failure mileage was 120,000.
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 Lithia Jeep Dealership staff in Grants Pass, OR were all shocked when the warranty claim was denied for this replacement given the number of EcoDiesel failures they had seen. With the systemic premature failures of these engines, the AEM class-action lawsuit updates, extent of recalls that are related to the engine and engine components, I have been disappointed in how Chrysler/Jeep have handled this situation, leaving the burden of their design flaws on their customers.

When stopping and suddenly accelrating jeep has a power delay and you have to hit the throttle agressively to get going or else I run the risk of getting hit by another car, but once you hit throttle the power is more than you need it or expected it, forcing me to brake or else I hit the pcar infront of me. I am still not able to make this work. I purchased the car used, I am still making payments and I barely use it because I find it extremely dangerous at time. The power doesnt come when I need it but when I do its too much, feels like I floored it and I have managed not to crash but its something someone should take a look at before its too late.
