2014 Jeep Grand Cherokee fuel system problems

Filed Oct 5, 2026 · Fuel system · ME

The dealer and Corporate Partner are refusing to perform the federally mandated Z46 safety recall (the federal safety agency 22V406) on my 2014 Jeep Grand Cherokee until they replace the supply line for a $1000, because they said it rotted/rusted. This factory supply line is made of nylon plastic and cannot rust. I suggest it blew out as part of a failing HPFP covered under the recall, and they misdiagnosed it. Furthermore, the technician and service advisor stated that they had not checked for any metal as part of the recall. I have asked for legal documentation for the estimate of parts and labor for the replacement of said supply line and have not received it.

This complaint is being filed regarding a failed and botched remedy of two federal safety recalls: the Crankshaft Position Sensor recall and Safety Recall Z46 (High-Pressure Fuel Pump) on my Jeep Grand Cherokee EcoDiesel.The vehicle was delivered to Kendall DCJR of Soldotna, AK for the recall services. The technician performed the recalls, but the high-pressure fuel pump failed immediately, resulting in systemic fuel leaking directly into the engine's crankcase oil pan. The fuel contamination thinned the motor oil, dropped oil pressure, caused the oil filter to collapse, and resulted in a catastrophically blown motor.Physical inspection confirms the entire fuel system is filled with destructive metal shavings and debris ("glitter") from the disintegrating pump, requiring a complete replacement of all fuel components and the engine assembly. The vehicle has been rendered entirely undrivable and has been sitting out of service at the authorized dealer for over 30 cumulative days. The manufacturer (Stellantis/Jeep) has failed to provide a safe, effective, and timely remedy for these safety recalls, and is refusing to issue a Corporate Rental Authorization (CRA) or alternative transportation while my vehicle remains grounded due to the safety defect's failure. This is a complete failure to execute a federal safety recall remedy in a reasonable timeframe.

My 2014 Jeep Grand Cherokee suffered a total intake manifold failure directly resulting from a secondary breakdown of Safety Recall W79 (the federal safety agency Campaign 20V‑699). Physical teardown at an independent facility exposed a 70% engine runner restriction and seized glow plugs due to volatile exhaust sulfur, creating an active fire risk. On July 9, 2026, LaFontaine Fenton was presented with clear mechanical photos and a continuous 2023 dealer repair loop under Customer ID [XXX], but formally refused to open a corporate STAR Case or dispatch flatbed transport to remedy this active safety defect.

My 2014 Jeep Grand Cherokee suddenly developed a no-start condition after previously operating normally. The vehicle would crank but would not start. The battery and fuel injectors were checked and replaced as needed, but the problem persisted. Based on the symptoms and known issues affecting 2011-2014 Jeep Grand Cherokees, the internal fuel pump relay/TIPM is suspected. This defect has been the subject of previous safety recalls because it can cause engine stalling or a no-start condition. Although my vehicle is not currently included in an open recall, it is experiencing the same type of failure. A failure of the fuel pump relay can leave a vehicle stranded or cause the engine to stall unexpectedly, creating a serious safety hazard if it occurs while driving. I believe this issue should be investigated to determine whether additional vehicles should be covered by the recall.

My 2014 Jeep Grand Cherokee Summit EcoDiesel (VIN: [XXX] ) experienced a catastrophic engine failure at approximately 116,000 miles while driving. The vehicle suddenly displayed an oil pressure warning, and I immediately shut the engine down to avoid further damage and potential safety risks. At the time I shut the engine off, the engine was not making catastrophic knocking noises and was not leaking oil heavily. The vehicle was towed to Astorg Dodge Chrysler Jeep in Parkersburg, WV. Before inspection, I specifically instructed dealership personnel not to start the engine because I suspected a serious oil-related issue and wanted to avoid causing additional damage. Despite these instructions, the dealership started and ran the engine anyway. After the dealership started the vehicle, the engine condition reportedly worsened significantly, including severe engine noises and much heavier oil leakage. I was later informed the vehicle would require complete engine replacement, with estimated repair costs ranging from approximately $10,000 to $24,000. At the time of failure, the vehicle was also subject to the unresolved Z46 High Pressure Fuel Pump (HPFP) recall, which had not yet been completed. I had previously been informed that recall parts were available and the repair would be scheduled. I am concerned that the unresolved recall and/or related fuel system issues may have contributed to this catastrophic engine failure. I am also concerned about the potential safety risk associated with sudden oil pressure loss and catastrophic engine damage while operating the vehicle. I am submitting this complaint so the failure and unresolved recall involvement are documented and reviewed.

My vehicle is a subject of recall 22V‑406 (FCA recall number Z46 [XXX] ), and the repair work for that recall was completed on April 26 of 2024. On April 23, 2026, the vehicle failed in the exact way described in the recall: loss of power, particulate in the fuel lines, failed high-pressure fuel pump.

Component/System Failure: The internal fuel pump relay within the Totally Integrated Power Module (TIPM-7) failed. This component is not available for inspection as it is an internal board-mounted relay, but the dealership-installed External Bypass Relay (Part #CBWPR091AA) and the failed fuel pumps are documented on the attached service invoice. Safety Risk: The failure caused an unpredictable engine stall at highway speeds in heavy traffic. This resulted in a complete loss of motive power while moving, creating an immediate risk of a rear-end collision and leaving the vehicle stranded in a live lane of traffic. Confirmation: The technician documented a terminal 'static pressure drop' to 35 PSI (Spec is 58 PSI). Based on this confirmed low-pressure state, the dealer required the replacement of both the Main Fuel Pump and the Siphon/Auxiliary Transfer Pump, alongside the installation of the External Bypass Relay Kit (Part #CBWPR091AA) to restore safe operation." Inspection: The vehicle was inspected and repaired by the authorized manufacturer representative (Larson Chrysler Jeep). I have also opened a formal case with Stellantis Corporate (Case # 96059987). Warning Symptoms: There were no warning lamps, MIL messages, or starting issues prior to the initial stall. The 'Long Crank' and failure-to-start symptoms occurred immediately after the highway-speed stalls. The vehicle would not restart until it had sat for a period of time, indicating a thermal failure (heat soak) of the internal fuel pump relay. This resulted in the vehicle being stranded in live traffic multiple times while waiting for the component to cool and allow a restart "Note: The attached repair invoice from Larson Jeep contains a clerical typo in the VIN (listing a 'D' instead of a 'B'). The dealership has been contacted to provide a corrected copy, but the technical diagnostics and repair were Selling Dealer: Titus Will Used Cars Lakewood, WA Servicing / Repair Dealer: Larson Jeep Puyallup, WA

I took my car to the dealer for the recalls. They are basically only putting a band aid on the issue. They are telling me they did both recalls but it didn't fix the issue. Klaben in Kent Ohio. They basically did just a flash on it but that didn't fix the issue (LOSS OF CRANKSHAFT POSITION). Everything I read said the reluctor wheel needs replaced and they are telling me the vehicle is too old and won't fix. This is all part of the recall. If you have any questions please call me.
