The speedometer or other instrument panel gauge may begin to work erratically at times. Our technicians tell us that the instrument cluster must be sent to a repair facility to correct this fault. The warranty has been extended on some of these units to 7 years or 70,000 miles.Google+

The entire dash cluster is dead at this point, but it started with the speedometer, then the tachometer. The entire cluster died at 243,000. It is amid other problems as well mainly involving electrical components.

First the speedometer would settle at 0 when the truck was stopped... And work its way up to beyond 120 mph at moderate speeds. About a week later, the water temperature gauge went haywire and read only between high and very high (and settled at above normal range when the truck wasn't running). In reading blogs online, I discovered a guy on Ebay from Minnesota who repairs these clusters for about $60... And has lots of positive reviews. I'm mailing mine off to him this week. By the way, removing the cluster is a pretty easy job... You can find a youtube video that shows the process that is excellent.

Speedometer would either not work at all, or get stuck in position. It was covered under the "extended" warranty, but I had to pay $263.25 for the part - labor was "free" from the dealer
