“While driving in Oyster Bay NY on a mild day, around 75-80 degrees, engine fan started get louder and louder as if the truck was in a high heat condition. Fan only kept getting louder, i was able to access the digtial temperature gauge and temp was reading over 250 degrees. However no warning light or message came onto the screen. When i contacted the dealer, they said to get it to them, but i could not drive it, because the temp was steadly increasing and ended up having to get it towed. (Temp got to 270). When the dealership contacted me, they informed me that it was a stuck thermostat, and that this was a known condition., however i dont see a recall for this.”

“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…”

“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,…”
