problem #1

Mar 222023

Sierra 3500 Denali 6.6L Turbo Diesel

  • Automatic transmission
  • 100 miles

Lane Departure Warning System does not function properly. They replaced the module, but still intermittently doesn't work. It is at the dealership today, but the Service Representative said they just don't work very well, depending on lighting and lines on the road.
