“I purchased a 1993 Gmc Sierra pickup for my son from my father who was the original owner. My father took very good care of it making all scheduled maintenances as we have done as well after purchasing it. My son was on his way to school when all of a sudden the steering column broke. He was unable to steer the truck and had to come to a complete stop after going approximately 50 MPH. Luckily he did not loose control nor did he crash head on into the on coming lane of traffic. Once stopped he couldn't get the ignition to turn off with the key. …”
