2023 Hyundai Sonata Cruise Control Problems

My concern is a potential unintended acceleration forward as. I was. parking vechicle. Sudden burst of speed, went thru shrubbery and off a 2 foot wall. Felt as if we were taking off a runway in a plane. Car went nose up over the wall and then dropped into a neighbor yard digging a divot, ripping rear left fender and bumper with some undercarriage problems. My spouse and I were seatbelted and not injured. I can not recall any safety warning until car stopped and then do recall a message being on dash but cannot presently recall what it said. Vehicle currently being worked on at collision center where Insurence Appraisor gave go ahead with estimate to repair damages

Purchased a new Hyundai 2023 Sonata from McGovern Hyundai Rt 2 May 22, 2023. After two weeks of driving the vehicle, I noticed it hesitates when I push down on the gas pedal. I had planned to have the dealership take a look but have a very busy schedule, the issue continued each time I drove the car to the point it was hesitating, basically pausing as I cross intersections. On the 26th of July I was driving on the highway, as I started to experience issues when stepping on the gas. Entering a tunnel in Boston, I pushed down on the gas pedal and noticed the car was decelerating, I was losing speed, in a panic in the center lane of the tunnel, I was able to get the car over to the far right. The car was shaking aggressively then finally just gave out and I called 911. They towed the vehicle to the police headquarters, I called Hyundai for assistance. Had some hiccups but two days later they were able to service the vehicle, supposedly found a faulty fuel injector. They changed out the 1 faulty injector test drive and said the problem was fixed. I picked up my car on July 28th 2023. There is something still wrong with the car, it still has some hesitation and now misfires. Have not heard from Hyundai, I was assigned a case manager and told someone would follow up, no one has reached out. So lucky my children were not in the car and that i'm safe. I could have been killed, others could have been hurt/killed. This should not happen to brand new cars.
