While driving the Wagoneer it shut down in the middle of road while at a stop light, and did a “hard” reset where all the systems had to boot back up before being able to start the Jeep. I reached out to local Jeep and to Service, and was told to bring it down so that they could run a scan. On my way to the dealership, on XXX , the Jeep did the same thing and shut down in the middle of [XXX] ( I major road here on [XXX]). I was able to start it back up and get to the dealership. Once there and after running the scan, I was told that there were active codes for the electronic power steering system and that this could of caused this issue, and that I needed to leave the Jeep with them, as it was not a safe to leave with it in this condition. They informed me that this is a known issue with these systems and that it can cause a low voltage situation and cause the truck to do a hard reboot. In the end it took 23 days for the truck to be fixed due to part back order. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

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.

Battery failure after car wasn’t driven for a few days. Left me stranded and had to get the vehicle jumped in order to take it into the dealership. If this had occurred during inclimate weather it could have placed me and my family in danger. This is the first failure we experienced since owning the vehicle. Dealership cannot replicate and says they cannot find a parasitic draw. No official warning prior to incident to occurring however the vehicle sounds like it cycles constantly while being turned off and sitting in the garage. Dealership replaced battery

Battery failure after car wasn’t driven over the weekend. Left me stranded and had to get the vehicle jumped in order to take it into the dealership. If this had occurred in I climate weather it could have placed me and my family in danger. This is the second such failure we have experienced since owning the vehicle. I purchased and now carry a battery jump starter for a new vehicle for fear of being stranded. That is outrageous for such an expensive and new vehicle. Dealership cannot replicate and says they cannot find a parasitic draw. No official warning prior to incident to occurring however the vehicle sounds like it cycles constantly while being turned off and sitting in the garage. Dealership had to perform bcm update and charged for this work.

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. During these episodes, the vehicle entered an unmanageable failure state: the transmission locked in Park, the electronic emergency parking brake autonomously engaged and refused to disengage, and the vehicle rejected all power cycles. Because the transmission was frozen in Park and the electronic brakes were locked, the vehicle could not be pushed out of the roadway. It became an immobile hazard in the middle of live traffic. Following these events, a Check Engine Light illuminated, and the vehicle now exhibits violent engine jumping, severe RPM drops at a standstill while in Drive, and active engine stalling. Twice, this total vehicle immobilization occurred directly within active roadways while I was traveling with my three young children. Being trapped inside a completely unresponsive, un-shiftable vehicle in the middle of a live roadway—unable to even push the vehicle to the shoulder—creates an extreme, unmanageable risk of a high-speed rear-end collision. Expecting a driver to navigate active traffic with a vehicle that randomly dies and completely locks its own brakes is a catastrophic safety hazard. The manufacturer is aware of this defect via STAR Case S2508000034, TSB 18-042-26, but has failed to issue a recall. A passive Technical Service Bulletin is unacceptable for a defect that causes complete vehicle immobilization in live traffic. A mandatory safety recall is required before this defect causes a fatality.

My 2024 Jeep Wagoneer L experienced automatic stop/start restart failures during summer 2026 travel. During one incident, we were stopped in traffic while exiting the [XXX]. The engine shut off during the automatic stop/start cycle but did not restart as expected. We had difficulty restarting it, leaving us unable to move in traffic until it eventually restarted. I was concerned about being struck or stranded in a congested tunnel exit area. Two batteries were replaced during the trip, one during service in [XXX] and another following the [XXX] incident. Mopar records list service at Jones Chrysler Jeep Dodge on XXX, at 22,409 miles, including a battery-related entry, and Chrysler Dodge Jeep Ram of Englewood Cliffs on XXX, at 22,814 miles, including electrical-system service. These are service dates; the exact incident dates may differ. I do not yet have the detailed repair orders identifying which battery was replaced at each visit or the diagnostic findings. The dealership subsequently advised us to disable automatic stop/start. We have done so and have not experienced another shutdown with it disabled. However, the vehicle continues to jerk or buck intermittently around 20–25 mph while holding a steady speed and sometimes during gentle acceleration after leaving the driveway. Lane assistance had also become unavailable before the summer restart problems began, and it became unavailable again on XXX. I do not know whether these issues share a cause. I am reporting the restart failures and continuing symptoms because of concern about another incident in traffic. Disabling stop/start has avoided further shutdowns so far, but I have not received confirmation that the underlying cause has been corrected.

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.
