Hi there, Yes I have had the same issue with my 2015 Suburban, how they can spend this much money and not build electronics and wiring correctly. In my 4 years I have had it break 3 times, only once under warranty in the first year, and even then they wanted to fight it. GM sucks and I will never buy another one. This past February I had it fix and then it broke in April. Recently had it in local Chevy dealership and it took them 3 visits to fix it and we just noticed 3 days later that the 3rd row dvd broke with no picture in screen, it was working when we dropped it off. This is absolutely crazy and GM knows it that is why they are changing to back of seats instead of middle.
All you do is get lied to as they never want to come good for it.
