Speed Control Cable problems of the 2003 Chevrolet Silverado 1500

Gm sent out a letter telling its customers that if you had a silverado (mine is a 2003) that has speedometer problems it could nbe replaced free of charge if it has less than 70,000 mile or 7 years. My truck started having speedometer problems when it hit 81,000, so even though its 5 years old I have to pay to have it replaced? its not like its a speedometer cable, its the whole cluster which is pretty expensive. I think gm needs to make good on this before someone gets hurt.

The contact owns a 2003 Chevrolet Silverado 1500. While driving 25 mph the speedometer automatically increased to 120 mph. However, the contact was still driving at 25 mph. The contact stated that this failure occurred on two other occasions while driving 55 mph. He disconnected the negative battery cable and parked the vehicle for twenty minutes. He then rehooked the cable and the speedometer reset itself. The contact had to perform this routine each time the speedometer got stuck at 120 mph. From the NHTSA website he discovered that thiswas an ongoing failure with this type of vehicle. The current mileage is 28,144, and failure mileage was 27,800.
