While driving approximately 35 mph the water pump started to leak. This caused the serpentine belt to become wet and slipped off the pulleys which caused the vehicles brakes and power steering to fail. I questioned the service advisor at the Ford dealer(henry day Ford) in West valley Utah and they advised they had not heard of the problem. To me this is a very important safety hazard for occupants and could be a liability for Ford Motor Company.

I woke up last week to the sound of a car alarm. I looked outside and the front of my Ford F 150 was engulfed in flames. It was so hot the tires melted into the driveway. We had not driven the truck in several days. It appears the fire started in the engine as the entire front of the vehicle is incinerated.
