  1. The update thing seems to be the ticket, my truck called for an update this morning which i did. After the update processed the radio no longer stayed on after the door was opened. Pretty bizarre if this type of repair science is upon us, but also quite impressive. Time will tell.
  2. I have a 2020 GMC SLT 4x4 with the 3.0 Duramax. Bought Oct 29 and driven only in the cold Canadian fall/winter weather. I have driven mostly diesel vehicles over the last 20 years, but the ride was getting too harsh in the 2500 series. This is a pleasant to exceptional ride and handling vehicle. It starts very well in the cold, as low as -25 Celsius (-13F)without being plugged in. I have 4000Klm so far and economy from day one averages 11.1 L/100KM (22.1 miles to US gal.) Best 100 KLM is 8.3L/100KM (28.3 miles to US gal) This is the best truck I have had in my time driving. I recommend it be considered by most everyone needing full size towing, comfort and economy.
  3. I am fairly certain the changing of the bulbs is not the cause of the issues in your case. Hopefully, this will fix itself and not be a major concern. Really like the truck.
  4. Good evening I just purchased a 2020 Sierra SLT with the 3.0 Duramax (2000miles). My radio does not shut off when you open the door. It did, but has not for 2 days now. Will be getting it looked into and will update this forum if I get anywhere. I have no mods or upgrades of any sort. Too old.
