What owners wrote
I was the owner of a 2018 Sonata until I was t-boned and the car was totaled. I started to make a left turn into a school parking lot when the engine kind of stalled or more like stuttered and did not go forward as usual. The oncoming car then struck me before I was completely in the driveway. My vehicle was totaled as was the other one. Fortunately no one was on the passenger's side where the other car hit me. However the seat belt did not engage which resulted in me slamming very hard into the steering column.
