problem #1

Mar 182016

Sierra 2500 WT 6.6L

  • Automatic transmission
  • 27,000 miles

Poor headlights compared to the 2009 GMC model year. Complained to the dealer, they found a tsb for this, but it was only a reflash to turn up the voltage on the light bulbs. Mild improvement. But still not good. That are almost dangerous on a wet dark night..can't see.
