Take it to your GM dealer to see if there is an outstanding recall on this issue. I could be something as simple as a vacuum leak or a bad cruise module. I wouldn't wait on that problem.

SOURCE: 2006 buick lacrosse - speedometer stopped working properly

Sounds like you need to replace your speedometer cable that runs from your dash to your transmission.

SOURCE: Speedometer stopped working while driving - no longer registers

This has happened on our van multiple times. Through some internet searches I have found a solution that works.

Go to your van and, with the ignition off, press and hold the trip reset button. You will see 'Sof' and perhaps some diagnostic test numbers will show up on odometer; the unit will perform a self-test, and the system will do a reset and should it should operate normally.

Cheers!

SOURCE: accelerator has surged many times, sometimes while

Did the 'Check Engine' Light come ON? Whenever the 'CHECK ENGINE' light comes on, the ECU (Engine Control Unit) sets a Diagnostic Trouble Code (DTC). These codes identify the particular engine management system which caused the light to come on. You'll need to use/find an OBDII (On-Board Diagnostic) Scanner to retrieve any code which have been stored in the ECU computer. Afterward, we might be able to help you DIAGNOSE and perhaps eventually fix the problem.
