I was coming back to the GMC family after spending 10 years with a Toyota Tundra !!!! Well first the headlights at night a terrible you better test drive it at night ?? Second the gas mileage is almost ridiculous, the tailgate doesn't fit properly it has a gap on the sides and everything gets dusty as I have a custom ARE topper . The sunglasses holder has to be for reading glasses as nothing fits . The seat will be wore out in 10 years as the leather is of poor quality. The SD car reader slot doesn't allow you to read trail camera photos?? This vehicle was designed for a person that wants to drive a truck not a real outdoorsman that would enjoy the usefull features we need and would use . 8/22/18 now the water pump failed this is ridiculous for a 3 yr old vehicle so much for the radio you now can’t program the radio also the power mirrors work randomly ? The motor is probably going out .

The day I brought the truck home I noticed that the heater would not change from defrost.Then after a couple of weeks water leaked on drivers side front and back.All carpet had to be replaced.Then water leaked on passenger side.The truck has 3100 miles on it and has been in the shop 16 days.Im wondering what will be next.Its obvious GM dosent build a quality truck any more.

Well folks I'm back we've been to the dealer 4 times the headlights are terrible . I asked the service manager to load his family up and take it for a spin as I hate to drive at night . The headlights are only producing 1250 lumens when they should be 2500 to allow for proper visual at night . Please give this vehicle a drive at night and try to turn onto a side road make sure you have the salesman in the passenger seat !!!!.The WiFi is always blocking your ability to use your smart phone as Gm is trying to sell WiFi packages should be illegal to jam your own vehicle ability to have a smart phone in the vehicle

Bought the truck in June of 2015 (used) after a very short ownership by the previous owner and since put on only around 25k miles. Never had any problems. Fuel milage is obviously not that great but even all things considered it could definitely be a bit better than it is (getting around 15hwy-10city) with regular gas. The cabin; even at highway speed is very quiet and reasonably comfortable. Ride quality isn't that great but then again what do you expect out of a HD chassis so i usually look past that. I've only ever used the truck for towing once, and it was a decently heavy load (trailer and an ltd country squire station wagon) and it did half decent the entire 150 mile or so trip...although it did struggle a little going up some steeper grades. Gas mileage went down quite a bit to around 9mpg average. All in all its a good truck and even 4 years later in 2019, its still holding its value good.
