I am writing to formally submit a dangerous and sudden electrical system failure on my 2024 Jeep Wagoneer. I purchased this vehicle brand new from Lee Jeep in Wilson, NC and it currently has only 38,000 miles—just 2,000 miles past the standard factory bumper-to-bumper warranty. This issue represents a severe safety hazard and appears to be a direct, consequential chain reaction resulting from a dealer-performed service and software flash completed just 1,000 miles ago. Chronology of Events: 37,000 Miles: The vehicle's thermostat failed. Lee Jeep replaced the thermostat and performed a required computer system software update. 38,000 Miles: Immediately following these updates, the vehicle began completely shutting down and stalling at stoplights and stop signs. Simultaneously, the Electric Power Steering (EPS) completely cut out, leaving me stranded in active traffic with heavy, unassisted steering. Current Status: The dealership diagnosed a blown main engine fuse and is demanding $450 to replace it. They have refused to cover this under a goodwill adjustment, claiming their local branch "cannot do it." A full vehicle shutdown and loss of power steering at intersections puts my life and the lives of my passengers at immediate risk. Unresolved Root Cause: A high-amperage engine fuse does not blow without an underlying cause. I am deeply concerned that charging $450 to swap a fuse without diagnosing the systemic current spike—likely tied to the recent software update or the auxiliary stop-start battery logic—will leave me stranded again. Proximity to Warranty: Given that the vehicle is a 2024 model and barely past the 36,000-mile mark, a catastrophic electrical failure of this nature should be covered by the manufacturer.

Within less than 24 hours of picking the vehicle up from the thermostat repair on XXX6, it began shutting off on its own and losing engine RPM, including while being driven on the freeway and while stopped at a red light. It shut off completely on its own two times in the first 24 hours back in my possession, with no warning that the vehicle was about to lose power. Losing power on the freeway risks a sudden loss of motive power at highway speed and a high-speed collision, and shutting off at a red light risks being unable to move out of an intersection or accelerate away from a hazard, with a heightened risk of being struck. During these failures the vehicle displayed a battery warning code and, separately, a "service transmission" warning; both appeared and then cleared. These symptoms first appeared on XXX, within hours of the vehicle being returned from the prior repair. The failures have not yet been reproduced by a service center; the vehicle is scheduled to return to the place of purchase, Grogans Town Dodge Jeep Ram on XXX for diagnosis, and the same vehicle was in this dealership's service department of another dealership 2 hours from our home because thats where we were when the thermomstat issue occured on XXX for the separate cooling-system failure. The vehicle is available for inspection on request. Mileage: approximately 78,000. VIN: [XXX]. (For context only: I have since learned that 2024 Jeep Wagoneers have been reported to have a battery/electrical drain issue that can cause the vehicle to shut off.)

The engine cooling system failed while my husband and I were driving on the freeway at night: the thermostat stuck closed and cut off coolant flow to the engine, causing it to overheat and become unsafe to continue driving. This occurred at approximately 10:00 PM on XXX roughly two hours from home over a holiday weekend, with two occupants in the vehicle. The vehicle had to be towed, but it took nearly four hours to get a tow truck, leaving us stranded on the freeway at night; because we were stranded so far from home, my [XXX] father had to drive two hours to reach us at 10:00 PM and then drive us two hours home, arriving around 1:00 AM, which put an elderly driver on the road late at night and created further risk. There was first a low oil pressure code and the engine was revving without the gas being pressed. Then that code went away and the engine overheating code came on along with an occasional battery code. The vehicle was diagnosed and repaired by Bud's Chrysler Dodge Jeep Ram between XXX and XXX the dealership confirmed the stuck thermostat and coolant cut-off and replaced the thermostat. The vehicle is available for inspection on request. No manufacturer, police, or insurance inspection has taken place to date. Mileage at time of failure: approximately 78,000. VIN: [XXX].

The engine shuts off unexpectedly when the automatic start stop system engages. At the same time the engine shuts off, the power steering warning light illuminates and steering assist is lost. The vehicle must be restarted to regain power steering and continue driving. This has occurred on multiple occasions, including while the vehicle was slowing to a stop in traffic. The sudden loss of steering assist while the vehicle is in motion presents an immediate safety risk to the driver, passengers, and surrounding traffic. This appears to be a widespread issue. Other 2024 Jeep Wagoneer owners have reported the same combination of symptoms, sudden stalling paired with power steering warning lights, in complaints already on file with the federal safety agency. Suspected causes reported by owners and dealers include a failing 12V or auxiliary battery, a Powertrain Control Module fault, and a Power Distribution Center or wiring fault.
