2014 GMC Sierra 1500 Denali 4dr Crew Cab 6.5 ft. SB (5.3L 8cyl 6A)
I bought this truck brand new and it started running like crap. I traded in my Chevy Silverado for this truck. Worst mistake ever! The transmission trys to find gears and the whole truck vibrates at speeds over 60mph. I took it in to be serviced 3 times and still no fix! I will NEVER buy another GMC again.

I have RUST on my entire frame (rails, cross members, and all welded bracketry off rails). I noticed this just 3 months after purchasing brand new. Apparently it's not okay for the Rancho shocks used to exhibit pre mature rust (as they were recalled earlier) , but it is okay for GM's truck frames to RUST after 3 months? The TSB is just a band aid. How do you prep and redo a closed box section of frame rail? Why would you use bare uncoated (non galvanized) steel? The coating on a scratch off lottery ticket stays on better than the black wax coating used! Disappointed Customer....

I purchase truck 03/21/2015 I had never own a gmc truck was so excited about this truck when I purchase it at 4104mi at time of purchase was told it was a new truck but a loaner.four month later truck went in to limp mode call dealer immediately was told bring truck in. That was at 11000mi.two month later at 13000mi truck started down shifted real hard call dealer again took truck to dealership could not find problem.3 week later truck went into limp mode again.Now I'm worried 14980mi.advisor told me that they replace cored and wire.I ask what cause this problem advisor said corroded spark plug code was p0300.really at 15000mi. Warranty is 2/28000mi.and was told I was the first this happen too hmmmm.FORD here I come.
First off, there was no pull-down selection for my particular truck, which is an SLE trim, 4x4 double cab with the 5.3 liter V8, so I selected SLT, which is actually close in my case as my truck has the All-Terrain package that includes most of the SLT upgrades (except the leather seats). While cloth, the seats in the All-Terrain SLE are buckets with a great seat heater feature that allows heating the entire seat, or just the back which I love on very long drives.
This truck is very comfortable, with a smooth and quiet ride and excellent (for a truck) handling. Steering actually has pretty good feel and the truck corners quite flat. The seats as mentioned above are heated and are very comfortable, with firm padding that holds up well on long drives. The steering is perfectly weighted, though like in all GM full-sized pickups I've ever driven, the steering wheel is an inch or so off-center (just they're design). I thought this would bother me, but honestly it doesn't.
Fuel economy tops 20 MPG if I keep speed under 75, but at 85 it drops to about 18 MPG and in town about 15 MPG, with my average over 35,500 miles at 16.2 MPG.
I have had no issues whatsoever with this truck. Thus far I've changed oil a few times, wiper blades once and thats it. Everything still looks and feels like new, which is more than I can say about the vast majority of vehicles I've owned over the last 30 years.

I purchased a dealer lifted new truck ( get everything in writing as dealer told me it would not effect warranty.... Straight up lie)
At 3k miles wipers went out
At 10k radiator was leaking
At 40k tranny was shifting funny was told the infamous " unable to duplicate "
At 50k Tranny was making horible noise, once again " unable to duplicate"
Blue tooth system is always messing up
At 55k radiator leaking exact same spot and GM refuses to replace
At 75k had tra by checked out again for grinding noise was told no issues
At 80k tranny goes belly up and dealer and GM refuse to warrant ( 5k put into a truck that's less than 24 months old)
At 85k it's time for my bi monthly radiator replacement, this time I go with an after market
At 93k traction control goes out
At 98k engine has a bad miss and runs rough
Over all nice looking truck with to way to many issues, GM will use any excuse to get out of warrant work and the trucks are just not made
