I was driving along in town and heard a real loud pop sound and the car jerked. The front started smoking heavily. I get off to the nearest parking lot and fluids had spewed underneath and there was a small fire from this that went out. I had two children both in child restraints that had to be removed from the vehicle, thankfully my husband was with me. It was towed to two repair shops whom both stated the PTU had exploded and broke the transmission as well. I tried to get assistance through Ford and have hit a dead end. It is at the local dealership where they claim the ptu exploded, broke transmission and cracked the engine block resulting in close to $14,000 dollars needed in repairs. This vehicle was running completely fine, no lights had been displaying on the dash. Consumer stated dealer is blaming the defects on a tread pattern on 1 tire(not size).
