Just so you know the mirrors do extend, just gotta do it manually.
I'm quite pleased my 2016. Maybe you should go to the dealer and drive another to make sure yours is running right. I read some one else felt under powered and turned out they had a air leak from factory, quick easy fix and they were 100% happy afterwards.
Also I drove a 2015 powerstroke right before buying my duramax. I thought its performance was no better then the duramax and the rest of the truck sucked. cheap plastic everywhere and horrible loud ride.
Doesn't the wireless charger automatically turn off if it dont detect a phone on it?
Current ride: 2016 Duramax.
Past diesels: 2002 silverado 2500, 1993 k3500 5spd, 1993 k2500, 1982 k2500.
