2015 Suburban LT, touch part still works. Took to a dealer, of course it is out of warranty, spent $150 and said they wanted to spend $400 more for a possible $1000 dollar fix! ... you may guess where I told them to go... Like the truck, first GM product. Had HORRIBLE service at dealer I purchased from and the above was the best I can find in town.

 

Update... touch screen stopped working now... and hold on... shocker... still no response from GM...

LAST GM will ever buy.
