Speed Control Cable Problems of Chevrolet K1500

Sometimes the speedometer works and sometimes it doesn't. At approximately 38,000 miles this first occurred and I called a nearby dealer to see if they could reset the computer thinking that was the problem. At the time they couldn't fit me in and asked that I schedule an appointment. I discussed the problem with a CO-worker and his 2004 had the same problem and was in the shop. Apparently it has occurred many times because the dealership told him it was 4-7 weeks to get new parts or they could send out his existing parts to be reworked. The delaer has said that a bullitin has been issued but no recall has been ordered. I would think that vehicles a year or two old should have a working speedometer. The way I have found to fix it is to stop and remove the battery cables and let the computer reset. Sometimes the speedometer goes to 120 mph and just stays there, even when the truck is not running. I am wondering if this effects my anti-lock brakes or my mileage readings.
