NHTSA Complaint #11440822 — 2021 JEEP WRANGLER

I was driving down the highway when the engine on my Wrangler 4xe suddenly shut off forcing me to cut off traffic to get to the shoulder. Numerous error messages were displaying but I did not have time to see them all. Final message I could see was "Charging System Error". After turning the Jeep off then back one the problem cleared. I suspect this was caused by the Adaptive Cruise Control system. It had started to brake hard for a car not actually in my lane. At the same moment people were pulling in behind me to move over for a police car on the shoulder. The Adaptive Cruise Control started what was a hard brake check on this traffic, so I overrode it by pressing on the accelerator, at which point it died. At the dealer they determined from the codes that the transmission control unit had shut off the engine control unit. Otherwise nothing could be determined as being wrong with the vehicle. Seeing all the other complaints of similar incidents involving Wranglers I think there is bad software code in the vehicle's control systems.
