2021 LINCOLN CORSAIR Engine Problems

The contact owns a 2021 Lincoln Corsair. The contact stated that the battery warning light and check engine warning light were illuminated. The contact took the vehicle to the dealer, where the vehicle was repaired; however, while driving 10 MPH, the vehicle stalled. The vehicle was towed to the dealer. The vehicle was not repaired. The manufacturer was made aware of the failure. The failure mileage was approximately 32,000.

This 2021 Lincoln Corsair is equipped with Auto Start/Stop technology. Auto Start/Stop Technology automatically shuts off the engine when the vehicle comes to a full stop and idles for more than a few seconds. Once the driver puts pressure on the accelerator, then the engine turns back on. It's simple, and some say it can save between 3-5% of gas in stop-and-go traffic.

Went to unlock vehicle but found it was unlocked. Tried to start car and noticed there was nothing in the car that worked, interior lights, dashboard monitors, all computer functions were out and could not open the rear hatch. Called Lincoln assist and they sent AAA. They tested battery and it was good, tried a jump start and nothing happened. Saw on the internet (Lincolnforum.org) that disconnecting the battery and reconnect the entire system will return to normal. Tried this with the tech from AAA and it worked. 2 hours on the road after the incident stopped for gas and shut off the car and when I tried to start the car the whole incident was back. Again had to disconnect battery and reconnect and it returned to normal. Please find out what is causing this before it shuts down while driving???
