I have a 2015 Silverado Lt double cab. About 3 weeks ago, my blinkers weren't working from the inside of the truck. I took my truck to the dealer and they reprogramed the screen. This morning when I first started the truck the whole screen froze, nothing worked. I tried to call OnStar, nothing (what if I had an emergency?). I tried using the radio, nothing. I tried using bluetooth with my phone, nothing. My blinkers weren't working. I went to my next appointment, about 20 minutes and when I started my truck again, everything worked.
I drove straight to the dealership to make an appointment for tomorrow morning. The scary thing is I only have 200 miles left on my warranty. I will fill you in on what happens after my service appointment.
