This is somewhat typical. Usually the Speedometer will stop at a certain point or not function at all.
Because the Speedometer usues a motor driven needle, replacement is probably going to be needed.
You can disconnect the Cluster for a few minutes to see if a reset may work.
Otherwise the best thing to do is to have Dealer connect Scan Tool to check Speed Sensor, Speedometer & PCM first, prior to replacing parts
