After sitting in stop-and-go traffic I noticed that the speedometer was reading at 100 MPH and I was at a stop light. At the time, I had less than 50,000 miles on my truck. Since then the speedometer was almost always incorrect. It has occasionally fixed" itself, but usually did not last more than a day or two. The needle was often buried past 120 MPH. A number of my friends and relatives with similar vehicles had the same problem. Currently I have not paid to have the problem fixed, but hope that it will be recalled at some point soon.
