The 8spd transmission in this truck went out at 7000 miles. Had to be in shop 3 different ocassion for them to realize it needed to be replaced. The two previous times they reprogrammed and made me put 500 miles on it before saying it didn't work. GM needs to make it right to all its loyal customers. So hopefully this transmission will not fail. Please do yourself a favor and stay away from these trucks till they fix the issues. After the new transmission I had issues again so I traded it in and lost all my money I had put down on it. This trucks trade in value was not very good. Plus the times it had been in the shop were on record so they couldn't certify it thus less money for trade.

I bought the truck new, within 5000 miles there were Transmission Issues, they replaced the whole thing with a brand new one, GMC wanted to see it !! within 2000 miles there were the same issues with this one, now a 2nd new transmission, within 3000 miles the tranny was acting up again !!! they wanted to replace it I said NO, I want a different truck 3 months of battling with GMC it cost me 2800.00 more to get a different new truck, I had less than 10,000 miles on a brand new truck !! now with 35,000 miles on my business partners same truck he has just had his transmission replaced and after 2000 miles he needs it replaced again, theres something wrong with the 2015 6 speed transmission, I'm worried now that my new truck with 20,000 miles on it will have more problems shortly, I've been a GMC customer for 30yrs and will continue, but they have issues with this 6 speed transmission, and they will for quite awhile.

Went to the dealer thinking new Suburban I ended up with a Sierra Denali! Briefly stated, I have had Suburbans for 20+ years to haul materials for my business and personal use i.e. hauling black labs, gear for various outdoor adventures, etc. I actually have used a Suburban for what the vehicle was initially intended! Unfortunately, the new recently redesigned Suburban is an engineering disaster for folks like me. The rear storage area is much smaller and chopped up. Also, if you have to crawl in the back you darn near need a ladder to get in. It's clear that GM has targeting soccer moms for the new Suburban. It's strictly a people hauler...period! So, I just happened to look at a Sierra Denali crew cab pickup. After a test drive, I was ready to buy. The back seat area is roomier than a Suburban and will seat 5 comfortably. I could go on and on, but the bottom line is I love this vehicle. Best of all, it cost far less than a comparably equipped Suburban!

Had the truck my first winter, only 5000 miles and the radiator hose was blowing fluid thru out the engine. 26000 miles and the 4 wheel drive was stuck in 4x4, later found out you should not shut engine off in cold weather conditions with the 4 wheel drive in gear. The heater in defrost does not clear the window all across the front window . This product is 100% in Mexico and the quality shows.

Stay away .... Been to the "GM Certified Dealer" shop 8 times since I put 30,000 mi on it. It started a shutter at 30-60mph not this thing shakes and shutters so bad at all speeds. Had two separate transmission repairs... TCM Control replaced twice and transmission flush. Do yourself a huge favor and do not buy a GM Sierra/Silverado 2014+ as they have nothing but horrid transmission issues. Also repaired on my truck was the split bench started shifting side to side. Driver Seat had to be repaired because it swayed back and forth on turns. Headlights are also very poorly engineered. Zero visibility in dark conditions.
