Pros: look great, nice mpg, Cons: head lights, can't see anything at night and worse in the rain; head rests, very uncomfortable too far forward; vibration in drive line while driving; no radio reception at all; transmission shifting problems; windshield wipers are worthless; dealer help anymore is bad at best. I'm done with GM

2015 GMC Sierra 1500 Denali 4dr Crew Cab 4WD 5.8 ft. SB (5.3L 8cyl 6A)
5 of 7 people found this review helpful

I took a week and test drove all the major brand trucks (minus Ford, just not a Ford guy and I regret not test driving one) at the end I ended up purchasing a 2016 GMC Sierra 1500 Denali (5.3l V8 / 8 Speed Transmission). I have personally owned 94 vehicles, sold vehicles at a dealership, was part of a dealership, so I am very familiar with anything automotive. I bought the vehicle in September of 2016, brand new from a dealership in Missouri (I live in Iowa) and I have put 4250 miles on it in the past 3 months that I have owned it. The first 5 days of owning it I realized I have regretted buying it. The first issue was the RUST! well as they call it rail rust/dust, it was on the inside of all the doors where the door meets the body of the vehicle, then I noticed spots everywhere else - I was told all vehicles have this, it's just that mine was the pearl white so it showed more - my thought was if I was paying $50k for a vehicle it should be perfect! (apparently not). Either way I had to have the dealership take it to a local detail shop and they took a clay bar to it (twice since they didn't do a good job the first time the rep says) but it still didn't get all of the rail rust off, decided to live with it - will be trading the truck in 2-3 years even though I bought it to keep "forever". Out of the trucks I drove and compared it to this was the best overall buy for what I was looking for - if I had to do it all over again I would buy a RAM 1500 EcoDiesel Limited (friend week after me bought one for $5k less than what I paid for the Denali). I test drove the Ram 1500, Toyota Tundra, Nissan Titan, and Chevy Silverado. The Sierra in my opinion is FAR better than the Silverado - just go drive both and you will see the difference in ride and overall feel - I figured it would be the same truck, but I was wrong. The Ram 1500 and Nissan Titan had the best features that the others lacked, keyless entry/start being the main thing for me - only the RAM and Titan had keyless entry - Huge Fail on GM and Toyota. The main reason I would purchase a Ram 1500 instead of a Sierra 1500 is the fuel economy - I do about 75% interstate driving and rest city and I am averaging 16.1MPG (that 16.1MPG is based on the last 4250 miles I have on the truck, I am currently with it being cold/snow getting 13.4MPG). Also not to mention when I completely babied it and drove extra economically it showed 18MPG - when I actually calculated (dividing miles by gallons filled up) I got a grand total of 15.9MPG. My friend has the same driving habits and in his Ram 1500 EcoDiesel (6 cylinder diesel) he is averaging 24MPG. I was ideally looking for the 6.2L and not the 5.3L engine, I have driven both - there's a huge power difference, the 5.3L is not powerful enough, not even for daily driving - it constantly feels like it's lacking power. The 8 speed transmission is what I was looking for - but isn't what I expected it to be, 95% of the time the transmission shifts GREAT, but that other 5% of the time when you are going slow and it's shifting between the lower gears it JERKS and shifts WAAAY more than you would expect a brand new top of the line truck to do. Either way, ideally I would love GM to contact me and give me some money back ($10k would be ideal) - this is a $35k-$40k truck in my opinion and not a truck with an MSRP of $60.5k OR JUST BUY IT BACK OFF OF ME (last 6 of VIN - 344961, contact me). Either way here are some pro's and con's: ---Pros: Looks/Styling, OnStar App (start/unlock/lock your vehicle from anywhere, first 5 years free), tailgate design/hydraulics, interior design, Car Play, Towing Mode (very smooth when towing / gauges) ---Cons: Gas mileage is a considerable amount lower than advertised, no keyless entry/start, paint is very poor quality (I even have the $1000 upgraded White Tricoat), the heated seats/heated steering wheel with remote start don't really work, the auto folding mirrors are a joke (all there is is a setting inside the menu screen to enable you to use the button on the door to fold them, what a joke), the truck is under-powered (5.3L - this does not apply to the 6.2L), lack of innovation/features (like the RamBox)

I just put a huge down payment on my denali 2015 on Jan 7 2016. Two days after having the car it was jerking before and after stop. I almost had numerous accidents in my new car. I went back to brickell motor's and asked them to give me a new car and I was told to leave the car for two weeks so they could check it? Are they crazy. I just purchased a 60k truck and they wanted me to leave it. I called gmc and after a 1 hour phone call I got directed back to the dealer. I went back to Brickell Motor's and was treated like a piece of crap. It wasn't until I threatened to call the media that one of the Managers came out to speak with me. Same story leave the truck. Heck no! I'm not getting a 20 day old car for repairs. Again I called gmc and was told that Marcia Owen and or Pete Bur would be calling me in 24hrs. I'll blog back if this gets resolved. If it doesn't I'm telling you all DO NOT BUY GMC PRODUCTS AND MUCH LESS FROM BRICKELL MOTOR'S IN MIAMI FLORIDA. THEY ARE EAGER TO TAKE YOUR MONEY AND TERRIBLE ON CUSTOMER SERVICE AT ALL LEVELS. THE SAD PART IS THAT GMC IS JUST AS BAD..

Drives like a luxury car. Interior is absolutely top notch. The quietest vehicle I have ever owned. Had 2014 Chevy, this is a step up in style and interior materials. Loving it so far. --Had the time truck for a year now. Overall great experience. The shifting from 2nd to 3rd can be sluggish at the wrong time. Probably my only major compliant.

Got my truck in April '15 and loved it - until it got hot outside. I've had two F-150's and a/c would freeze you out. Here in Alabma summer's are very hot. A/C blows hard and very cold, briefly. Then the A/C cooling stops while the hard blowing continues. And since we have such hot summers it feels like hot air blowing on you. It does this back and forth continually. Of course once the truck cools off enough then it not so bad. But it's a good 10 minutes- long enough to start sweating! It's as if the compressor switches off and on while the blowing remains the same. Dealer kept it two days and said it was working normally. I work indoors in an extremely cold business and am a slim guy so when I leave work I'm not overly hot so sweating my rear off on my drive home is unacceptable. Im wondering if the dealers hear this a lot and know it's baked into the design. Either way I will be trading it near years end when prices drop on 2015's. In the deep south with our long, hot summers and high humidity good A/C is critical. UPDATE: A/C still sucks. Truck has always had a vibration at HWY speeds which I attributed to the original tires. Finally after 2 and 1/2 years I needed new tires. Got a set rated the best for All Season/ HWY for my size and truck still vibrates at HWY speeds causing the change in the center console to clink! I will definitely be getting an F-150 when my lease is finished in July 2018. The A/C issue is a real deal breaker for me living in the Deep South.
