problem #1

Sep 172019

Sierra 2500 SLE 6.6L

  • Automatic transmission
  • 22,800 miles

My truck still had low mileage, and the rear slider window was used very, very little (maybe 10-12 times), and it got stuck open and would not close anymore. Closed it by hand. Must be poor installation, or poor design. Read online that others have had the same problem. Should be a recall on this problem. Gives less faith in GMC Trucks.
