Used 2017 GMC Sierra 2500HD Consumer Reviews

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.

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 .

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.

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

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!

Still a Happy Momma!!!

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