Mine stopped working at 60plusk miles and I went to the dealer who wanted $700 to fix it. After speaking with the service manager they still would not admit this is common and wanted the $700. I bought a GPS for the MPH. That is the only thing that wasnt working in my gauge cluster. You would think a speedometer should last on a truck like this. I had a 78 corolla with 200k miles or more and the speedo was still working.
