there is a tsb on this and the HCU has to be replaced then after that a scanner has to put the correct gear ratio along with tire size iin to fix this. I'm not sure if a dealer will do this at this point due ot age. also it only does it while cruise control is engaged from 74-76 mph. see pic for qualifying vehicles.
