NHTSA Complaint #11427442 — 2021 JEEP WRANGLER

I was driving at night on a 4-lane highway at approximately 55 mph southbound in the left lane. My hybrid vehicle had less than 1% of battery power and was running using the gas engine. With no warning the vehicle suddenly experienced a sudden deceleration to less than 10 mph then a warning light came on stating "service charging system- place vehicle in P and start engine. Fortunately there were no vehicles in close proximity either in front, behind, or in the lane to my right, so I was able to make it over to the shoulder before it came to a complete stop. At that point I received an alert from my UCONNECT app that stated "Your 2021 Jeep Wrangler Unlimited was unable to charge." It also stated to "Get service immediately." I placed the vehicle in park and attempted to start the engine with no response. I repeated the procedure and the engine started after which I was able to drive home. I had the vehicle towed to the dealer the next morning where, after two days, the dealer returned the vehicle and told me they could find nothing wrong. no codes in the computer, and no information from Jeep on any similar problems, despite getting the aforementioned alert received from the UCONNECT app. My main concern is that this type failure, the sudden engine failure/deceleration with no warning either inside or outside (brake lights), especially at night, can easily result an accident. I was very fortunate that I was on a highway with other cars near me. A crowded street, highway, or freeway would be a totally different story.
