2024 Jeep Wagoneer: sudden loss of power

Filed Oct 6, 2026 · Electrical, Engine · NC

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.)

Vehicle: 2024 Jeep Wagoneer (Base Model) The vehicle has experienced ongoing and progressively worsening engine performance failures, specifically involving unstable RPM behavior and loss of power during idle and re-acceleration from idle. These defects have been present on multiple occasions and occur under normal operating conditions. While stopped at traffic signals or intersections, the vehicle frequently exhibits sudden and erratic RPM fluctuations, followed by a sharp drop in engine speed resulting in complete engine shutdown. These shutdown events have occurred both while the vehicle is in Park and while actively positioned in traffic, creating a hazardous condition. In several instances, the engine stalled unexpectedly while the vehicle was stopped at a red light, requiring an immediate restart in an active traffic environment. In addition, when transitioning from an idle state to acceleration, the vehicle has demonstrated abrupt surging and jerking behavior, causing sudden forward movement. This creates a significant risk of unintended acceleration and near-collision events, particularly in congested traffic conditions or when stopped closely behind another vehicle. The vehicle was presented to an authorized Jeep dealership for inspection. The dealership advised that no diagnostic fault codes were present and no defect could be identified. However, during the dealer’s evaluation, the vehicle did stall while being allowed to roll into the service bay in an idle state, directly corroborating the reported condition. Despite this occurrence, no corrective repair was made, and the vehicle was returned without resolution. The frequency and severity of these symptoms have increased over time, resulting in a vehicle that is unreliable and unsafe to operate. The continued occurrence of engine shutdowns and erratic acceleration behavior presents a clear and ongoing safety risk to the driver, passengers, and surrounding motorists.

This is the 3rd time the Jeep Wagooner has "bricked up." The vehicle will shut off without notice and lose all power, the emergency brake comes on and stops vehicle abruptly. This poses safety risk to driver passengers and surrounding vehicles. The car will not be able to be restarted for 30 secs. Once car is restarted, dash lights flash everywhere and car loses power steering. This happen 1st time 2 weeks after I bought a brand new 2024 Jeep Wagoneer. I took it to dealer and they told me it was defective battery. They replaced battery, it has now done it two more times. I took it to dealer again and they once again claim it was defective battery again. 2 defective batteries in 18 mos of new car? There is something else going on w/electrical system in this car that drains batteries and abruptly shuts off vehicle.

While firing on the highway in the middle lane my car lost all power as soon as an Engine overheating light came on. This almost caused a larger pile up as cars starting swerving all over the highway to avoid my vehicle. I was able to safely coast to the shoulder without being hurt. After getting it looked at I was told my vehicle had a faulty thermostat yet by 2024 wagoneers VIN was not included in the batch they had put out.

Vehicle is 4 months old and has 2300 miles on it. Randomly and suddenly the vehicle will lose power while in traffic. No steering or engine power. It will abruptly coast to a stop, put itself into park, and stall. Several lights will come on. All the lights but the check engine lights disappear after letting the car sit. The car sometimes turns over only to stall a few seconds later. If left to sit for 30 minutes or so, it will drive again. Obviously a car that shuts off and loses power while driving is a big safety issue. I am unsure if I should drive it again, in case it happens at the wrong time. This has happened on three occasions over the last 350 miles. 5/6/24 5/22/24 6/15/24 The vehicle has spent over thirty days at the dealer. They do not know how to fix it. On 6/15/ 24 one of the owners of the dealership was able to see the mechanical problems 1st hand.
