problem #1

Mar 152019

Sierra 1500 Denali 5.2L

  • Automatic transmission
  • 20 miles

The electronic/computer does not operate correctly. Here is a list of the intermittent problems (a restart of engine sometimes clears it up for a while...)

Radio sound goes off after boot up, the knob or screen shows bar working but no sound.

The front camera stops working during a parking procedure.

Scrolling circle on Heads up display.

Distracted driving warning comes up multiple times in one day and then not for several weeks of months.

The cooling seats do not come on during remote start.

Could not turn off accessories - I had to start car to shut it off.

Can not adjust volume or turn off radio during boot up.

These problems happen all the time, with duplicate directions in the heads up display.

Secondary phone does outgoing calls.

Does not drop out of cruise control during collision alert.

All are related to the computer.
