Cruise Control problems of the 1997 Ford Mustang

While driving in a 55 mph zone, I attempted to set my cruise control. I did this successfully. However, about 5 minutes later, the car began to slow down as if the control was disengaged. After I realized this, I pumped the brakes to disengage the c/c. It took several attempts of pumping the brakes to release control. Once done, I was too paranoid to try using the c/c until recently. I decided to try it with no traffic around in a 35 mph zone on a straight away. The cruise control simply would not engage. I took it to an ase certified shop in ellsworth, maine to have the problem diagnosed. The shop said it was a relay that was burned out. The relay was replaced at a cost of 48 dollars for parts and labor. After replacing the relay, the c/c still does not work. I am more concerned with the sudden slow down and non-release of speed control to the driver than with getting my c/c to work again, but I would like to know what is to be done about this. Especially since it happened on a maine highway in heavy traffic. Thank you.

Vehicle's engine started racing and brakes did not respond to stop vehicle. The dealer told the consumer they could not find a problem. The consumer took the vehicle to an outside mechanic who disconnected the cruise control and the consumer has not experienced anymore problems.

The cruise control self activated which caused the vehicle to speed up and as a result the driver lost control of the vehicle. During this incident the brakes did not work. The driver was not injured. The vehicle was totaled.
