In 2005, he was involved in a car accident in Peer, Belgium. He was accompanied by his girlfriend, his cousin, and a friend. His car was rear-ended while stopped at a routine road check, immediately killing his girlfriend but only inflicting minor injuries to Kah. In Roda JC's next match, referee Bjorn Kuipers held a minute of silence to in honour of Kah's girlfriend. During the game, Arouna Koné took his shirt off to reveal an undershirt which bore the inscription "For Kah". The referee showed Koné a yellow card, a decision the commentators criticized. Kuipers said afterwards that he had not seen the text on Koné's shirt.
