problem #1

Jan 022025

Denali AT4 2.7L

  • Automatic transmission
  • 3,000 miles

This was the first issue I experienced with my truck. Also the only one that has actually been resolved.

The interior lights would flicker or not work at all when doors were opened, several presses of the switch could typically get it working but next time the doors were opened it would be back to that same behavior.
