My 2004 SSR showed me going at 115 mph today (among various other illegal speeds). In park, or braked at a stop light, it registered between 40 and 60mph. Does anyone know how to fix this?

Chances are that the Vehicle Speed Sensor has lost its mind. This might even bee a loose VSS connection.

Did you get any CEL warning? It should be something like a P1500 or similar.

I have no idea what you are talking about. Could you transcribe the acronyms to englis?. I am quite a lay-person when it comes to mechancics, but I do so much appreciate your reponse.

The other gauges are not crazy. My RPM ranged from 1400 to 1800. Is there something else I should check?

You need a new speedometer cluster. VERY common problem on GM trucks from 2003-2005. About $500 from the dealer. GM issued a warranty extension on their full size trucks for this problem, I don’t think they extended the warranty on SSR’s.
