On the early morning of April 19, 2007, Kyuhyun along with Super Junior members Leeteuk, Shindong, Eunhyuk, and two managers were hospitalized due to a serious car accident while returning from a "Super Junior Kiss the Radio" show. The front tire reportedly burst, causing the car to hit a guard rail, spin twice, and flip over. Kyuhyun, who was sitting behind the driver's seat, suffered the most serious injuries including a fractured hip, broken ribs, and facial scratches and bruises. He subsequently developed pneumothorax from a broken rib piercing his lungs and remained in a coma for four days.
