2024 Jeep Wagoneer L Engine Problems

“More than ten times in approximately the past week, the car has unintended engine shutdown/loss of motive power while parked or while driving, with and without the Automatic Hybrid Electric Stop / Start button activated. Last occurrence the vehicle failed to restart or have any indication of power for 30-45 minutes.”

“While crossing an intersection, at low speeds (<5mph) the wagoneer immediately switched to park due to a failing auto park safety system. It left us stranded in the middle of the road while the car required two shut offs and restarts, all while watching cars drive by us. This has occurred twice in intersections, twice at stop signs, and three times pulling out of our driveway in the past three months.”

“The contact owns a 2024 Jeep Wagoneer L. The contact stated that while driving at slow speeds, the vehicle shut off with the Auto Engage message displayed. The failure persisted with the Check Engine warning light illuminated. The vehicle was taken to the dealer, and the auxiliary battery was replaced; however, the failure recurred. The vehicle was taken back to the dealer and remained with the dealer. The manufacturer was notified of the failure, and a case was filed. The failure mileage was approximately 28,000.”

“Component Affected: ELECTRICAL SYSTEM / ENGINE AND ENGINE COOLING / FUEL/PROPULSION SYSTEM The vehicle exhibits a severe, life-threatening defect involving the dual-battery and starter relay architecture (related to manufacturer code P2AF6 / Starter Relay 3 Stuck Off). On three separate occasions, the vehicle’s Auto Start-Stop system engaged normally upon braking, but completely failed to restart the engine when the brake pedal was released. Instead of restarting, the vehicle experienced a total software lockup where it forgot it was turned on. …”
