Check Engine Light On problems of the 2013 Hyundai Sonata Hybrid

Tl the contact owns a 2013 Hyundai Sonata Hybrid. While driving 20 mph, the contact stated that the vehicle started sputtering with the check engine warning light illuminated. The vehicle was taken to napleton oaks Hyundai (1985 river oaks drive, calumet city, IL 60409) to be diagnosed. The contact was informed that the battery was faulty and that the engine needed to be replaced. The vehicle was not repaired. The failure persisted. The manufacturer was notified of the failure. The vehicle was included in NHTSA campaign number: 20v7460000 (engine). The failure mileage was 77,946.

Was driving vehicle and "check charging system" message displayed on the console. The vehicle lost power, I could not accelerate so I had to manevour to the far right of the freeway to come to a stop. Turned off the vehicle then re started. Check engine light remained on.

I was driving on a interstate and suddenly I see "hybrid system warning message" + "check charging system" with continuous alarm beep sounds. I had to immediately move to the right most shoulder on the interstate (which I was able to as car was still on with engine running). Once, I moved to the shoulder, I turned off the engine and restarted the car with check engine light. It would turn on fine but wouldn't move and immediately it throws up the error. I have attached the pics for reference. Since car didn't turn off in the middle of highway, I was safely able to move it to the curb. I cannot imagine what would have happened if car had shut off. I had it towed to the nearest dealer and there are working on it. I just had a 45000 miles factory servicing with same dealership where the car got towed to and they checked on all the green boxes. Within a week, I had this issue. This is what troubling me.
