Occasionally the volume knob and steering wheel controls will stop responding. The volume bar graph at the bottom of the infotainment screen will get glitchy when you turn the knob with no volume response to the system. I have to shut the vehicle off for a minute or two and restart. This seems to fix the problem, but it's starting to happen more frequently. Has anybody else had this happen on their Yukon, Tahoe or Suburban ? What was the fix ?
