There were other cars behind me and the car would not restart.  I had to get a jump and it restarted. The 48volt battery is faulty INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

JEEP WAGONEER 2023 POWER TRAIN

Vehicle: 2023 Jeep Wagoneer Mileage at time of incident: 43,400 miles Component: Engine Cooling System / Thermostat Incident Description: This vehicle has experienced two separate thermostat failures since purchase. The first failure occurred the day after I purchased the vehicle, in April 2024, at only 104 miles. This time the vehicle overheated /stall pattern even after confirming coolant was at a sufficient level. The second failure occurred on Monday, June 22, 2026, at 43,400 miles. While driving with my wife, son, and son's friend as passengers, the temperature warning indicator activated, signaling an engine overheating condition. Shortly after, the engine lost power and stalled completely while the vehicle was in the middle of a busy intersection. With the engine off, I had no power assist for steering or braking, which made it extremely difficult to maneuver the vehicle out of the path of oncoming traffic. My family and I were nearly struck by other vehicles while attempting to get the disabled Wagoneer clear of the intersection. The recurrence of this failure at relatively low mileage (43,400 miles on a 2023 model) indicates a potential design or manufacturing defect in the cooling system, not an isolated incident. The second failure resulted in a complete loss of engine power in active traffic, creating an immediate safety hazard to my passengers and to other drivers on the road. Repair history: Failure #1: April 2024, 104 miles Failure #2: June 22, 2026, 43,400 miles Cost of most recent repair: Approximately $2,000

I submitted an issue last week for the vehicle putting itself in park while driving and loss of brakes while driving. I brought the car to an authorized dealer and they told me they fixed the issue. It is now happening again. This is a major safety concern!

Vehicle started up on its own and continued to run. Key fob was laying on a night stand. No messages were displayed in car. I was able to turn it off.
