Buzzy,
Under the VIP smart wheel is a device called a "clock spring" that transfers the information from each of the buttons on the steering wheel. It is not uncommon for these to fail. Further down the steering column where it tilts, there is a plug that connects wires. Sometimes that plug comes apart. The information from the smart wheel goes to a command module located in the drivers consol. If you go to technical> coach assist> on Beaver Home page, you can scroll down to the Smart Wheel trouble shooting guide. Hope this helps, Fred
