2009 Hyundai Genesis cruise control problems

Tl* the contact owns a 2009 hyundai genesis. While attempting to stop for a traffic light, the vehicle accelerated independently. As a result, the vehicle crashed into the rear end of another vehicle. No injuries were reported and a police report was filed. The manufacturer was made aware of the failure. The vehicle was taken to the dealer. The technician replenished the brake fluid and was unable to diagnose the failure. The failure recurred on three different occasions, all involving a crash without injuries.

When I was trying to enter an expressway from an entry ramp, I stepped on the gas and got no response. The engine did not rev up as it would if the car was in neutral. I coasted to the apron , turned off the car, and restarted it. The gas responded normally after restarting but the engine light stayed on. I took it into the dealer and they reprogrammed the engine control unit, which, so far, has fixed the problem. I was told that the computer just lost track of the accelerator position.
