The driver of the vehicle stopped the car when he noticed the fire and shouted to his wife and children to get out, according to a China Press report.
The family quickly grabbed their belongings and exited the car before it started sliding backwards down the slope.
A video of the incident showed the car rolling about 50m down the road as other vehicles and pedestrians hurried out of its way before it collided with an SUV that could not evade it.
A Pahang Fire and Rescue Department (JBPM) spokesman said the department received an emergency call at 1.44 pm and officers and firemen from the Genting Highlands fire and rescue station rushed to the scene.
He said upon their arrival they found a Hyundai Elantra car which was believed to have caught fire at KM 2.9 was sliding backwards along the road.
“An operation to put out the fire was carried out but 80 per cent of the vehicle had been razed. A couple and their three small children escaped unhurt.
The department’s forensics unit is investigating the cause of the fire.
