Other Fuel System Tank Assembly problems of the 2018 Chevrolet Traverse

This is a recurring issue: today while I was driving my vehicle on us 98 in gulf breeze, FL I made a left hand u-turn in a 45 mph zone and the vehicle suffered severe fuel starvation. I started the u-turn out of a complete stop. Even with the accelerator pedal floored it took the vehicle over three seconds to recover. This happened with over 3/4 of a tank of fuel. Luckily, I gave myself plenty of space with approaching traffic and I had a left hand turn lane to use or else I would have been in an accident. This issue has only occurred when committing u-turns. The vehicle gave no indications to any problems. I have brought this issue up with the dealership where I bought this vehicle and either they can't duplicate it or gm is not going to fix this problem until there is a lethal accident.
