2021 KIA STINGER Engine Problems

Since April I have been having the same issue. Sometimes when I am stopped and the autostop is supposed to shut down the engine, the engine just sputters and if I hit the gas nothing happens. I have to put the car in park and shut it down then restart it. I try to shut the auto stop off when I get in the car but sometimes I forget. It has happened at over 20 times that I have documented over the last couple of thousand miles, many times in dangerous locations, in the middle of interactions or waiting for a light. The engine light has also gone on and off over the last couple of months. The car is now at the dealership and they say the high pressure fuel pump is leaking. I see there has been a recall in specific Kia Stingers, should my car be involved...

My transmission/engine and brake system failed. I was slowing down to probably 5 mph to make a right hand turn into my driveway from the street when the engine started racing. I heard a loud whine and the car started to speed up. I jammed my foot onto the brake to slow down but did not have the time to try to put the transmission into neutral. The car was not slowing down so I turned right to hit my tree rather than proceed straight and crash into my garage. When I hit the tree there was a large jolt and the car stopped. NO airbags deployed and I felt the impact on my right foot that was firmly on the brake; I checked to make sure I was not inadvertently pressing the accelerator. This same issue with the engine suddenly revving happened one time a year ago but stopped...

The car started to slow down and once I came to a stand still. The car would not start!

JUST PURCHASED A 2021 KIA STINGER GT AWD NEW ABOUT A MONTH AGO. JUST OVER 1000 MILES ON IT NOW AND ENCOUNTERED A CONCERNING ISSUE. SITTING AT A STOPLIGHT WITH THE AUTO START/STOP OFF, TRACTION CONTROL OFF AND IN SPORTS MODE, I PRESSED THE GAS PEDAL AND THERE WAS A SLIGHT HESITATION FOLLOWED BY A PRETTY FORCEFUL LURCH FORWARD. AS I APPROACHED THE NEXT STOPLIGHT SEVERAL HUNDRED FEET FURTHER AHEAD THE CAR COMPLETELY STALLED OUT. I TOOK IT TO THE DEALER AND THEY COULD NOT DUPLICATE IT... OF COURSE.
