I loved this truck ...I say loved because I no longer have it. 2000 miles into ownership I had my first wreck of nearly 40 years of driving. My beautiful truck got T boned by a guy doing about 65 mph. My truck flipped with me in it and all the curtain airbags deployed along with OnStar immediately asking if I was ok. The other driver was taken to the hospital with injury's (He's doing good now) but I climbed out of the truck without a scratch. I hope that I never need the safety features on the GMC again but I can't say enough about them.
btw I am on my way to buy my next GMC now.
Just bought this truck last month and have been to the dealer three times for repair. First repair was changing 3 of the 4 tires due to excessive road force, the truck would jiggle very bad at 70mph. Second dealer visit the truck heater does not turn off, the dealer told me this is a common characteristic of this truck, no fix but the did tell me to leave the air on at all time I will get less gas mileage but it wont be so hot in the cab, Nice? Third Dealer visit was not big deal but come to find out GMC intellilink does not support iphone6. Basically I get a phone call it will shut off nav, radio, etc. and not return. I have to manually turn power back on to device. The most frustrating is randomly it will our of the blue start playing my phones music even if my daughter is watching a cartoon in back, music will just turn on from no where. Pretty nice experience thus far for a $62000 truck.
I have driven nothing but GMC trucks since 1985. This truck is the smoothest, technology driven, comfortable, safest and the best GMC I have ever owned. All of my buddies are drooling. Before I would lend out my truck to friends and family to use for all sorts of reasons....now no one can use it....I'm being stingy. I'll only let my wife drive it....but she don't wanna drive it....which is just fine by me. I can't say enough about just how great and reliable this truck is. I have the Iridem Metallic color and believe me when I'm driving around town I get plenty of thumbs up. The interior even beats out my Acura RDX for features and comfort. My advise is buy one....if you can get a 2016 buy it....Kelly Blue Book says the price for the 2016 is much better and lower than the 2017 for essentially the same exact vehicle.
I have researched lots of pickups, and the best one out there is the GMC Sierra. The ride, quality of all of the equipment and the quietness is second to none. I am getting far better gas mileage than the window sticker shows. Why would anyone even consider any other brand.
I have had the truck for a month, I am up near 2000 miles. I live in North NJ and appreciate the ride of the truck with the garbage roads we have. Up in North Jersey, the terrain is all hills, almost nothing flat. In local driving, I have been averaging about 17 mpg, not bad considering the terrain and the size of the vehicle. We took the truck to the outer banks for a week, 520 miles each way, on this trip I averaged 22 mpg, fully loaded, 2 adults, 2 kids, a dog, and truck bed full of beach gear, clothes, food, grill supplies, etc, etc. this trip brought the lifetime fuel economy for the truck up to 20mpg. pretty impressive. I will admit, I monitor my driving and kept it in v4 mode as much as possible, it worked. I am impressed. While in the outer banks I saw one period of driving, the first 100 miles leaving for the way home where I averaged 25.7 mpg, slow steady state, traffic free flat land, 55mph cruising. Amazing. The trip was 11 hours each way, factoring in stops for bathroom and food. Not a single complaint, everyone was comfortable beyond compare. The connectivity was loved by the kids, as was the ability to have all the electronics charged. While the dog would have preferred a yard, even he had room to move and get comfortable. Moving up from a Subaru Legacy, this was an obvious upgrade, what is surprising is that a vehicle this size is actually more efficient than a car that weighed 2000lbs less, and had a 2.5 liter 4cyl turbo engine. Finally, the GMC dealer experience has gone upscale and every dealing I had with them, beginning to end, has been easy. No quality based issues with the truck yet, and hopefully none on the horizon. There is a steep learning curve with the technology of the truck and the personalization available, but a good long trip like that helps to sort it all out and learn what the options are.
