speedomter will not work until car reaches high speed on 1998 Lexus LS400

my speedomter does not work at low speed only when I reach high speed, has there been a recall on thismodel? once it reaches high speed it works fine until I drive it again ususlly a few days later.

Most likely the speedo cluster itself is failing. If cruise control and mileage odometer still work the cluster will most likely need to be replaced. There are sources for reconditioned units.
