NHTSA Complaint #11460980 — 2017 HYUNDAI TUCSON

My 2017 Hyundai Tucson refuses to accelerate after a complete stop at a traffic light, or just refuses to change gears after making a turn, or simply just lose power although on cruise control while drive on the freeway. I have reported the issue several times to Hyundai and the dealership, it seems that nothing can't be done and Hyundai is not taking my concerns seriously. I am not afraid to drive the car since I have a long commute to work, I escape several accidents before because the other drivers were cautious and kind enough when they notice that my car couldn't accelerate. Drivers have blown the horn at me on the highway because the car refuses to accelerate or change gear while I am driving. I can press the gas pedal all the way down, still nothing. When I press the gas pedal down, the engine start shaking and making a weird noise while the car still not accelerating or changing gears. I also notice that I am burning more fuel than expected, and I always get below the average for typical MPG. I personally consider this car is unsafe to drive, and I am strongly thinking about trade it in.
