Used 2017 GMC Sierra 2500HD Consumer Reviews

Great Diesel Truck

Bought this SLT model after trading in a 13 2500 HD Denali. Needed to pull a 16000 lb Fiver camper. This Pickup has extreme power and smooth shifting. Thought about getting a single rear tire toner till I realized the only difference was an extra leaf spring is all. I had automatic step sides that come down when you open the door and that made access in and out easy even the wife enjoys it. I have 13000 on it now. I guess I don't see any issue with the headlights seem the same although I did notice at the parts counter upgraded bulbs on the counter so maybe that fixed the issue. I especially like the bright lights in the side mirrors for backing up at night. No problems with the leather or accessories, I did get extended warranty just in case. mileage varies about 8 mph pulling the camper and 17 mpg on the highway not pulling town about 15. Seems like a great pickup more to come.

Duramax

This is a 6.6 Duramax crew. There was not an option when writing a review. I bought this truck used with 44k miles on it in February 2018 from a private party. This is the nicest vehicle I have ever owned. I have no issues with the headlights so they either were replaced or people are over reacting. This is my daily driver and I average 17mpg. 9 miles to work and mostly in town driving. I love towing with this truck!!! We have a 25’ Travel trailer and it’s like it’s not even back there. I love the exhaust brake and tow button. I am trying to think of something I don’t like about it but it’s hard. The interior is awesome and the seats are comfy. We have taken a handful of road trips already and can’t wait to take more. It has every option except the heated steering wheel. I even have the remote start which is awesome!! I added oversized tires and wrapped the grille and mirrors. I also put a spray liner on both front and back bumper. The rest is stock. This is a beautiful truck inside and out. I get tons of compliments. I will be keeping this for many years.

Black & Chrome Beauty

I’ve driven many diesel powered pickups here at home and abroad for over 35 years. The new, 6.6L Diesel Duramax/Allison, is the center of Sierra’s Universe and maybe a home run for GM against its competition. The new hood scoop design brings conversation at every refueling stop. To bad Edmunds didn’t include any photos of this hood, on their review. This is a large pickup and not a sports car but folks this truck is a thrill to drive. It handles the road seconded to no other heavy duty pickup I’ve ever driven and again I’ve driven many. My wife, (5’ 115lbs), drives this vehicle with ease and can even parallel park. It’s quite ( wind, and tire noise is minimal and no diesel clatter! ),the interior is cavernous, the leather is top grade, the control knobs are large and easy to manipulate, storage and cup holders are everywhere, the infotainment system has been upgraded regularly and the voice recognition has improved. The torque this engine produces from approximately 1650rpms and flat throughout the rpm range makes towing my 12,000lb travel trailer with ease. I can’t wait to go out west and enjoy the Rocky Mountains. I only have 10k miles on it, I may add another review in the future but today I have to hit the road in my 2017 GMC 2500HD Diesel Sierra Denali. I did give it a couple of 4 Stars because, it didn’t have lights in the glove boxes and center console and no automatic up/down lighted running boards but the was easily rectified.

Duramax!

There is no drop-down option for the Duramax Diesel version. Traded in a 2014 Denali 1500 for the big boy. I love this truck. No car/truck is perfect but the Duramax is the best Diesel engine on the road IMO. Sometimes the radio is quirky when plugging in my iphone so I just stream over bluetooth. I've noticed that the power steering takes more arm strength when maneuvering tight spots, more-so than other truck brands. The headlights are a less than great and should be recalled. I am hoping the new headlights that come on the 2016s will be interchangeable. I love my truck. It turns a lot of heads.. especially mine!

1st American Built truck in 20 years

This is an excellent truck, I was looking for a diesel from all the American trucks, I test drove all the trucks and read about all of them. All the reviews on GMC Denali HD2500 Diesel Duramax were dead on. I only had one issue when I first purchased the truck which was a leak with my master cylinder. They fixed it without hesitation and also painted the part of the frame below the master cylinder that took out the paint on the frame. I purchased the truck on November 30th, 2016 in Idaho, it now has 42,000 miles, we go back and forth between California and into Canada and everywhere in between quite a bit. First the interior, it's an extremely quiet truck, very minimal road noise. The Denali package is very comfortable, especially when it's blowing snow -26 degrees, you have the heated seats, heated steering wheel and just a comfy truck to drive. The only gripe about the A/C or heating system would be no vents in the back, it would be nice to have that and also more USB outlets in the rear for my kids while traveling long distances. The Duramax engine is an excellent motor, with the Allison transmission, it has lots of power and can pass multiple 16 wheelers without even sweating. The power band is very smooth as is the shifting on the transmission, we recently purchased a property in the NW and had to do some 4 wheeling to get to some of the lakes, it's a big truck but wasn't an issue to get back to these places. The sweet spot on this motor is 75mph, it will get 20 mpg, not bad for a 7,700 lbs truck. I still have the original Good year tires, they still have good life but will need get some winter tires for where we will be. I haven't bought an American car or truck for almost 20 years because of past bad experience with quality, I think all the American brands have really improved and so has GM brand, no complaints, great truck and if you're looking to haul a 5th wheeler or horse trailer, this will not be a problem.

Life long GM fan is loosing faith.

Some painted bumpers do not hold up. Eight months old and my bumper has no less than twenty chips. Some as big as a quarter. The dealer did not want to stand behind it and said don't bring it back here... Wow.

2015 Sierra HD diesel

So, yes. The SD card reader is pretty much useless. But all of the storage is amazing. The 6.6 is amazing along with the Allison transmission. I'm getting 17 in town and 20-21 on highway. Towing my tractor around is a breeze almost forget it's behind me. I did read the other reviews and the gap at the tailgate is real, and it does let a lot of dust in, However you can buy a seal kit for it. The safety features are cool. With the vibrating seats, lane departure detection, and back up camera, if you crash and it's your fault. It is actually your fault. bottom line I've owned a lot of vehicles, other than a minivan which I haven't owned but have been in and was amazed at the comfort and room this is the best and most useful vehicle you can get.

Who says Valentines are always red!

Picked up a stone blue 2016 2500 Denali from Bayer Motors in Comanche TX. Best truck ever, as my wife says. 500 mile drive to dealer was definitely worth it. Looking for a big loaded truck? Call Jeremy. It’s been a year and this truck has been a real workhorse. Pulling trees and clearing/hauling are no problem. Has been our best truck to date

Disappointed

I bought my truck as a Certified Pre-Owned Vehicle almost 2 years ago with the primary purpose of towing a 35' travel trailer. It had about 16k miles on it when I bought it and currently has less than 45k miles. We went with the diesel (model in the review says 6.0L since diesel wasn't listed as an option) since we eventually want to get a heavier 5th Wheel camper. I'm now considering getting rid of it due to the number of times I've had to return for service. The check engine light has come on 3 times in the past 2 months (EGR valve, mass airflow sensor and DEF heater). The truck left us stranded out of town with the camper when the mass airflow sensor failed. Besides the check engine light, there was a power steering fluid leak (known by GM due to Service Bulletin) and some sort of known issue with a bad weld on the diesel exhaust that apparently causes excessive smoke. I'm anticipating that being a problem one of these days. Not sure that I can rely on this truck for what I bought if for.I'm extremely disappointed so far and since this is my first time purchasing a GM product, I'll likely not return as a customer in the future.

Lots of wows but some why did they do this's?

Be sure to take this truck on an extended test drive. I was in the car business for 30 years and must be a slow learner but didn't heed my own advice. The cabin is very nice and comfortable which is important because we are driving long distances pulling a 5th wheel. Performance and towing capability are good but I think the published tow rating is optimistic. I am pulling a 14,500# unit and feel I am undersized. GMC rates this truck to pull 17,100- it's a diesel. The engine and trans are fine but the suspension is light. My other sore spot is the the sloppy steering. It's light without an load and terrible when pulling. I wouldn't recommend this product and will be not keeping it for long.

Wanted to love it but....

I really wanted to love this truck. Impressive interior, nice ride and loads of power in the Duramax diesel and excellent transmission. Unfortunately inside of 50,000 miles I have had to replace a NOX sensor, DEF injector, and had the fuel level sensor blink out and come back on 500 miles later. The worst though, is the REGENERATION problem. I have had the particulate filter regeneration mode come on 4x in the last 7500 miles. Twice it had to go to the dealer for a "manual" regeneration. The truck went into reduced power mode and left me pulling a trailer in the Rocky Mountains at 30mph up hills. Sadly it had the potential to be a great truck for towing and long distance driving but if it cant do what it is designed to do than its pretty much useless.

GM Quality

only 1700 miles on the truck and had it in the dealer twice for an oil leak. The oil pan has surface cracking, apparently acceptable to GM as it is on every truck. The wax coating on the frame can be easily removed by a fingernail and already has rust coming through mainly on the joints as if it was not applied properly or the coating method is simply insufficient. I actually bought 2 of these trucks and both have had paint issues. the 1st truck had the 3.73 axle, which has a poor tow rating of only 9200 pounds or so. this information cannot be found on the website and the website shows you cant even get the 3.73 with the gas engine. sunglasses holder is oddly shaped and won't fit regular sunglasses. the manual shift mode doesn't allow you to shift up when coasting downhill or something. the truck always seams to be down one gear lower than it should be when coasting and tow mode is off. the passenger tow mirror is very poor for visibility and doesn't show the side of my trailer as my f150 did. the led lighting is cool but there are wires that can get snagged under the bed rails. ride is more firm than previous models which I like. Ipod playback is horrible. very slow to respond and often doesn't work at all. dealer said it works fine. air conditioner lowers for phone calls which is cool. towing uphill isn't very good. the truck bounces between 2 gears, one which is excessively high and the other is to low to maintain speed.

Poor Quality Truck

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.

Looks great till you start looking

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 .

Can't drive at night,and WIFi jammed !!👎👎

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

2015 GMC Sierra 2500HD SLT 6.0l V8

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.

New Duramxx

Folks were nice and knowledgeble. Unfortunately i asked for a loaner pick up or a large SUV and was stuck with the smallest Buick SUV that i'd ever seen. Not the dealers fault, but there is still a tapping in my Duramax engine that they say is normal, this is the noisiest Duramax i've ever owned, and i've had 5 of them. All the others were a pleasure to drive with plenty of power, this one is pathetic. The only reason i'm keeping it is because the new Ford front ends are ugly, as soon as Ford changes their headlights i'll be getting rid of this GMC and going back to a Ford F250 King Ranch. It's very doubtful that this will be published but as stated below, you have my permission to publish... Still same issues with a little over 16,000 miles, still will buy a Ford next time. Have 26,000 miles on this truck now. Still has tapping in Engine and still waiting for Ford to update their front end look, when that happens this GMC is history.

3rd 2500HD SLT and Love it

Still a Happy Momma!!!

This truck had what I needed !!! I Love My Truck !!!

Truly Professional Grade

The GMC Sierra 2500HD is as solid as trucks come. The 6L power plant is fantastic and the cab is the most comfortable yet!

Best Truck I ever bought

I love the performance of the vehicle. The comfort and the power. I do not like the price of diesel currently. Your drop down menu does not have the 6.6 Duramax option which is my truck.

Amazing

I love it it rides great very comfortable and it has every action you can think of.

Monster towing

Just a little while Rough riding

Does what I needed it to do. Great truck.

Pulls a house down and will outrun most vehicles.
