“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…”

“My 2014 Jeep Grand Cherokee suffered a total intake manifold failure directly resulting from a secondary breakdown of Safety Recall W79 (NHTSA 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 Son just bought the car from a private party. On our way home the engine light and a lightning bolt icon illuminated on the dash, followed by the vehicle going into limp mode. We had the vehicle scanned for codes and it came back with P0336 (crankshaft position sensor performance). After much investigation online, we found out that this is a known issue with the crankshaft position sensor and, most importantly, the tone wheel on the back of the engine. We looked up recalls on the vehicle and found a safety recall had been issued. While some vehicles affected received replacement of the tone wheel and sensor, others just received a software update. This particular vehicle received the software update. The issue is that the magnetic material on the tone wheel delaminates from the tone wheel. This is a costly repair that should have been fixed correctly from the beginning, not just a software patch. It is a safety concern because it is dangerous when you are traveling at highway speeds and it goes into limp mode.”

“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,…”
