I was driving the car moving in reverse to exit my driveway. I placed the car in Park and while the engine was running I exited the car. Upon exiting the car, the car immediately started to roll forward and crashed through my garage door leveling it to the ground. The car continued moving forward into the garage and came to a stop blocked by built in shelving at the back end of the garage. I could have been injured had the car started to roll while I was exiting the car or had some been in front of the car. No warning lamps or messages prior to the incident. The car has a safety feature if moving in Drive or Reverse and the driver door is opened the car shifts into Park. That feature failed. The car was inspected by a Hyundai dealer and claim no error codes found and dismissed any other information as provided in this report

While parking my 2023 Hyundai Sante Fe, I hard pressed the break and pushed the Park button. The engine revved up and the vehicle took off instead of going into park; smashing into a building. The parking block was 6ft from the building. The engine accelerated to a high enough speed that it totaled the vehicle completely out.

The insurance reps are supposed to be following up on the mechanics diagnostics currently. There were no warning lights or anything on before the issue occurred as this was a brand new vehicle with only 8,000 miles on it.
