2019 Hyundai Tucson drivetrain & axles problems

I was driving approx 55mph on [XXX] in my 2019 hyundai tucson when the check engine light came on and the engine started to stall. I felt the acceleration dying down in the middle of busy highway traffic. Gray smoke started coming from the hood cracks. I luckily was in the right lane already, so when I could I veered off to the shoulder and the car quit. The smoke was increasing badly. Ppl from the highway were yelling its going to blow up get away from it! I was so scared.

Sporadic hesitation when starting from a complete stop. This has happened to me about 15 times, usually when pulling out into traffic. The car has 4000 miles and has been in service about 6 months. The service manager.stated they have no other complaints but is probably due to the "smart" transmission adapting to different drivers. I understand that there was a recall for 41,000 2017 tuscons for the same issue.
