Essex Fire and Rescue Service said the fire started while one of the cars was being given a jump start and it soon spread around the vehicle to two others.
Filmmaker Jamie Price and his partner Danielle, both 32, bravely waded into the deep water of a ford to rescue the motorist in Ingatestone, Essex on Sunday.
