Filed May 8, 2026 · Electrical, Engine · OH

Vehicle was driven for 5 minutes before alerting that it was overheating. While attempting to pull into a safe location off of a main road, the vehicle would not allow me to accelerate. This left our family stranded in the turn lane. I was unable to restart the engine or shift into drive.

The thermostat failed causing the vehicle to go into a reduced power mode while climbing a hill with a trailer. The dealer has a technical service bulletin for this issue but the overheating can call engine damage or an accident when the vehicle has reduced power. There were no warnings on the cluster until the car was already in a protection mode and power had been reduced. The cluster coolant temperature gauge is slow to respond and not accurate.

While driving my 2024 Jeep Wagoneer, the vehicle experienced a sudden and complete loss of power without warning. The engine shut off while the vehicle was in motion, including during a turn. When this occurred, I lost power steering, which made the vehicle difficult to control and created an immediate safety hazard. Prior to this incident, the vehicle had ongoing issues including overheating, repeated check engine lights, and power steering warnings. The vehicle has been taken to the dealership multiple times. A thermostat repair was previously performed, and at a later visit I was told there was an electrical/battery wiring issue that was repaired. Despite these repairs, the problem has continued. The loss of power while driving placed my safety and the safety of others at risk, especially since the failure occurred without warning and resulted in loss of steering assistance. I no longer feel the vehicle is safe to operate, particularly when transporting my children. The issue has been inspected by the dealership on multiple occasions; however, the root cause has not been permanently identified or resolved. Warning lights, including the check engine light, have appeared intermittently prior to the failure. The defect appears to be recurring and

While driving my kids to school on the freeway I received an alert telling me that my engine was overheating! I was barely given any warning of the rising temperature to allow myself to pull over safely. It never informed me it was rising, only when it was redlined near the max engine temp to which I had to immediately find a place to pull over. I didn't have enough time to get to the next exit 1 mile away, and had to pull over in an unsafe area and turn the car off until the engine cooled down while cars whizzed by us. Once cooled down enough, I was able to drive 1 mile to the next freeway exit but had to immediately pull over again into a center median as it was again overheating very quickly. My local dealership came to get the car and took my kids to school and me home while they inspected it and found a failing thermostat and water pump. I have only had the vehicle for 9 months and it only has 15,800 miles! This should not happen, at all, on a $135,000 vehicle. I also happened to notice a failing battery (no audio warning of this) on the display while scrolling through the menu looking for the engine temperature! So a brand new car has a failing battery, thermostat and heat pump..... unbelievable.
