2008 GMC 2500 Diesel

I bought this truck from a local used car dealer. I drive this truck mostly through the mountains of southwestern PA hauling my travel trailer. I previously owned a 2005 F250 diesel. There is absolutely no comparison between the two trucks. This GMC outperforms the ford in every way possible. I never thought I would say this considering my grandfather, my father, and I have been ford guys our entire lives but the proof is in the way the truck drives, handles, pulls, and the reliability I have experienced with this truck. I have driven this truck for more than 15,000 miles and overall I am completely satisfied. I have to say that this is by far the best truck I ever owned.
Very Pleased

Overall I am very pleased with this car and would prefer it to the rest in the bunch. The RAM did have a slightly better ride, but the towing capacity just wasn't up to par. There are several annoying things though: 1.The dash and center stack are kinda ugly and just dont look right 2.The headrest are in a akward position 3. The steering wheel doesn't telescope

My 1st 3/4 ton. I have the 6.0 gas with a 6 speed hydramatic. Everyone told me it would be a gas hog. I get an average of 18 mpg mixed driving. For a gasoline engine, it's a torque monster. I think it would pull a mountain. Very powerful acceleration, smooth and quiet for an HD truck. On a bumpy street, you will spill your coffee! It is a big, intimidating looking "AMERICAN" vehicle. Nice standard features like the satellite radio, onStar and integrated trailer brakes. My only complaint is that the cab "creaks" when you hit a harsh bump. This is a truck for real truck lovers. Volvo, Honda and Toyota drivers stay way. This is a real truck, built to do a real truck's job.
Excellent HD choice & great value

I got one of the first 08 2500HDs off the line as a custom order back in Aug. 07. For what I paid, this truck is an amazing value when compared to the F250s and Ram 2500s out there. The gas V8 has plenty of power and tows a 5000 lb trailer with ease. At first I had a problem with the transmission not downshifting easily in the 25-50 mph range, but the dealer flashed the ECU and now it's more responsive (although a bit less smooth- shifting - before it was like silk). Fuel economy has been mostly around 10-11 in the city, anywhere from 12-18 on the highway (the faster you go, the worse it gets). Most impressive is the quality. The interior and overall feel of the 2500HD is very solid.
Great "novelty" HD pick-up truck!

No one really needs a heavy duty pick-up with cooled seats and a heated steering wheel, but wow, this truck makes me smile! The driving dynamics are excellent, and I find the seating very comfortable, even on long hauls! The exterior look is awesome, as well.

This is my 3rd Duramax and they never cease to amaze me. They get better every generation. Im a farmer drive around 1,500 to 2,000 miles a week on probabaly 75% gravel roads and my previous ford and dodges couldent handel the roads or the mud i travel in. My Duramaxs have had the smoothest ride most comfertable to drive and in my opinion the best for pulling because of the allison transmission. Farmers are probabaly the hardest on veicles and the 2010 GMC 2500HD with the Duramax and Allison can definatly stand up to the chalanges i put it up to and my lead foot probably doesent help either.

I wrote my first review in June after trading in a 2004 F-150. It has only got better and better. Absolutely no issues. Fuel mileage has gone to over 23 MPG on a recent hiway only trip of 600 miles, to between 15-18 MPG back and forth to work and weekend trips. I have not had this kind of acceleration since my '61 Vette'. There are no rattles or any fit/finish problems. Only oil changes and tire rotation. I would not trade this truck for any other on the market. I did extensive reseach and I am so glad I choose this HD2500, Duramax/Allison. I would recommend this truck to anyone, no hesitation.

Well designed, well built truck that is a pleasure to drive, but it struggles to pull my small 6000lb 5th wheel trailer over some moutain passes. ATF temps up around 215 deg although total weight well within published rating. Front end styling is ugly.

The fuel economy of this truck leaves a lot to be desired. My truck is GPS'd so I am only able to drive the speed limit without getting in trouble. The best I have ever got for fuel economy is 14.8 mpg (imperial gallons). The quality of the truck is less than desirable. In cold weather (less than -20c) the back doors will not latch completely without slamming them hard. I actually knocked the molding off the door trying to get it latched. When the doors are closed they squeak and rattle so bad you have to turn the radio up. I have had to install a second battery to get the truck to start after sitting for more than 3 days. The airbag computer already stopped working and needed replacing.

I think it is a very good truck. But I can tell you I think a tin can has more thickness than the sheet metal used on this truck from past years. It is so thin I am amazed it is holding. I also noticed a lot of the quality is gone everything is cheaply built and poorly attached. Other than that the duramax and allison combination is by far better than Ford and Dodge.

This is the 6.6L with the Duramax/Allison combination, not the 6.0L. I previously had an 05' with similar features but wasn't worth the buyout at the end of the lease. There are things I liked about the 05 that the 08 lacks but most of all, I'm very pleased with the truck. Towing is great. Crewcab 8' bed is a long truck though. Park it at home if you intend to go into a city.

This car is simply amazing in every single regard. Just looking at it with its chrome and black paint give me butterflies. Everything's Perfect: Exceptional Ride Quality, Excellent handling, sharp and handsome interior, macho exterior, insane towing capacities, almost unheard of amounts of torque, heated and cooled seats,-I could go on all day. This vehicle is also a charm off-road, capable of passing going through anything although Front, Center, and Rear locking differentials would help contribute to its off-roading prowess. Towing is also done in comfort and ease as the engine does not even begin to strain even under the heaviest loads. I would not think twice about buying another one.

Was missing my truck and the GMC 2500HD was the fit for what was ailing me.I looked at fords dodges and toyotas and the GMC just looked and felt like it meant business. Ride is good for a HD and the acceleration is great.I seam to be able to achieve approx 18-20 mpg with mixed driving,However this goes down quick when you feel the need to drive spirited.Seats are plenty big enough for 6 foot tall 260pnd man.Sits up higher than most in class and on a wt comes with quite a good bunch of features,XM,Onstar PWR,WIN,LOCK. Mine has heavy duty everything and is pretty much a rolling mountain of solid steel.

This is a diesel, always garaged w/69K miles. Also washed routinely including winter,superior maintainence. The list of repairs goes on forever: computer reflashes, glow plugs, fuel injectors, throttle body, steering column, all parts of the diesel exhaust system. It needs a new air conditioning compressor, and now the ultimate insult - rust above both rear wheel wells. Body panel rust problems went out in 1977 when manufacturers went to galvinized body panels. GM is so incompetent they don't put decent rust proofing on their trucks (serious rust also under the hood on the hood latch). Big mistake buying this truck, poorly engineered,QC and manufacturing below par. Tells you what GM thinks of its customers

Have my new 2500HD 4W for a month now and very pleased. Overall truck is superb and beats the heck out of my older Dodge. Pulls my boat like it's not there. Ride is good and mileage is running avg of 17 mpg. I got the split buckets with console and love it. Ditto the comment that tires could be a bit larger. Really very happy with the purchase.

I use to own a 2008 Dodge ram 1500 5.7 hemi, and put 40,000 miles on it in less than 2 years. Fairly happy with that truck, and I have not encounter not even one single issue. Looking for more power, and better style, more options/better comfort/better quality, so I've tested all of them out there. The only one which satisfied my demands was the gms based on manufacture options that was installed like on board info system, back-up camera and sensors, on star system, teptronic 6 speed, auto-lights, shift turn-signal on the mirrors and more cabin space. So far after 9 months I'm very very satisfied with the quality and performance. I highly recommend to anyone this brand name gmc.
15 months later, still a great truck

This is definitely a Cowboy Cadillac. Performance wise, the gas V8 has all the power you'd need and tows my 7K # trailer with ease. The tranny shifts smooth but as another reviewer said, make sure you get the TCM flash for better kickdown response. The 2500HD 'pure pick up' interior on the SLE not only looks great, it's durable and functional as well. The front seats are great for long road trips. I'm getting about 12 mpg around town and up to 17.5 mpg highway at speeds up to 65. Above that, it nosedives into the 12-14 range. Overall, I'm completely happy with my truck after 15 months. I've had no problems and plan to keep this for a long time.

Bought my 2500HD 4x4 back in August. 8500 miles later, I still love the performance, comfort, and looks of it. I've made one 900+ mile trip towing a 4,000 lb. trailer, and it drove like there was nothing attached to it. The interior comfort is excellent. The seats are very comfy, and the quality is outstanding. I have not had any problems to speak of. I'm real impressed with this truck. The only downside is the gas mileage (to be expected). I average 12/13 in the city, 16-18 highway (depending on speed) and 12.5 towing a trailer on the interstate. Reckon the 6-speed auto helps the MPG a bit.
Duramax/Allison combo is a beast!

This vehicle was a replacement for a 2005 2500HD Duramax SLE and the engines are nothing alike. The new Duramax and six speed Allison is quieter, smoother and the towing power is incredible. We are towing a 35 foot travel trailer and it is like there's nothing behind you. The Z71 package does increase the stiffness but the ride is excellent. The interior rivals my '07 Denali. If you gotta tow, this is the one to buy.

This truck is by far the worst riding vehicle i have ever owned. I understand it is a HD, but come on GM, you're not always towing with it 100% of the time. I cannot believe the research and development guys at GM designed it that way. The rear end bounces 60% the time when empty or partially empty. tryed changing shocks and tire pressure adjustment. helped out about 5%. The new 6 speed tranmission in my truck needs work. There is a delay in shifting between 2nd and 3rd gear. This happen 10% to 20% of the time but is annoying.When the delay happens engine racing anywhere from 200 rpm to 1000 before the shift takes place.Tranmission engages harshly when shift happens. Look elsewhere.

I am just approaching its first 1000 miles, so 13.8 ave. mpg of the 6.0L gas engine in wet to snowy suburban/hwy driving may improve in milder/dry weather as it gets broken in. The SLE1 interior trim is a step up from your average work truck with comfortable seats and leather wrapped steering wheel. A smooth quiet ride for a heavy duty truck under most conditions. Feels heavy, but stable and turns on a dime when you want it to. The 26 gal tank may seem limiting, but that is still good for mid-300 mile range, farther than most people would drive without taking a break. Overall it would be hard to find a better truck.

I traded in a 2004 F150 4.6L with 25,000 miles to get a 2008 GMC 2500 6.6L diesel. The performance is unreal. I am getting over 13 mpg, which is the same as the 150 on Premium and I get 3 times the power. The ride, fit and finish are as good or better and the information center is a real boon. The shakedown will continue for another six months but for the first 30 days I could not be more pleased.

This is a decent truck, but NOT with the 6.0 and GM 6 speed. You HAVE to get the Duramax if you need a 3/4 ton truck. The gas motor with fly by wire throttle, and GM 6 speed, is a horrible combination. It is a death trap when trying to merge with traffic, especially in conditions when you are on and off the throttle. There is up to a 3-4 second lag where absolutely no throttle input is given to the engine, no matter how hard you press on the accelerator. I believe GM implemented this so their tranny wouldn't explode. The engine and tranny computer work together, and the tranny computer tells the engine computer to not give any throttle until the tranny is ready (it never is).

I recently purchased a 2010 2500hd 6l gas truck with 6 speed tranny, i am very pleased with the towing and ride quality of the truck, it pulls the 7000 pound trailer with ease, i would recommend this truck for anyone looking for a cheaper alternative rather than diesel.it has 200 km but i am sure fueld milage will improve, currently said 14 mpg highway towing 10 mpg, but not broke in yet.

This my first 3/4 ton truck. Now have 9000 miles on the clock. I have owned about ten 1/2 ton trucks over the last 40 years. I have owned mostly Ford trucks. GMC has really done well with this truck. It is the 6.0 gasser. I haul a travel trailer and perform routine around the house hauling. The powertrain and load performance difference between the GMC 1500 5.3 and 2500HD is huge. I get better gas mileage pulling a trailer with this truck vs. my 2008 GM 1500 5.3 gasser. I have been getting 17mpg on the highway without a load. 11 mpg pulling a 7000lb trailer on the highway. I believe the GM HD trucks are the way to go with either 6.0 gasser or the Duramax / Allison combination.

First off, after researching diesel trucks for over a year, it was clear that the Duramax/Allison power train was the "gold standard". I recently installed a Banks air intake, programmer, and exhaust system ($2500) and the performance is startling. Stock, average fuel economy was 16.2 (70 mph+ freeway); I hope the Banks package increases that up to 2 mpg. I stopped to watch a local, weeknight rodeo event in Paso Robles, CA and there were eventually 40+ trucks with 20-30' trailers, all diesels: 1 Chev, 3 Fords, the rest GMCs.

I owned an early 2001 HD 2500 with an 8.1/Allison. While solid, fuel consumption, oil use, and piston slap made ownership less than desirable. After several years of Toyota and Nissan ownership, I ordered a 2011 GMC Duramax SLT Crew. The 2001 and 2011 are similar in ride and appearance, but power from the 2011 is considerably greater. The Duramax is quiet and interior noise is low. It has impressive electronics, and fit and finish appear excellent. Interior is nice but lacks appointments. Other than the large center console, there is limited storage for small items such as sunglasses. The exterior lacks tie downs and storage. This is my sixth GMC and first one in ten years. I'm back!

Recently purchased an 09 GMC 2500HD with the 6.6L Duramax diesel 4WD. Came from an 08 Toyota Tundra 5.7L and the GMC can not only haul twice the weight and tow 5000lbs more but it also rides smoother when empty. It returns 20mpg unloaded on the highway and the engine note is just enough to remind you that you're driving a diesel but quiet enough to be mistaken for a gasser. The interior is also a nicer place to be than in the Toyota, with more style and materials of a slightly higher quality. The Allison transmission is very smooth and always shifts at the right times. Test drove against the F250 and found the GMC a better all rounder, that stopped and accelerated better. Payload equal.

I previously owned a 1999 Silverado 1500 4X4 Extended Cab Standard Bed and a 2007 Sierra 1500 4X4 Extended Cab Standard Bed I wanted to upgrade to something more powerful with more room. While I really don't need it for towing at this point, I can only imagine how great of a towing vehicle this will be. I am very impressed with the power of the Duramax diesel, as well as how quiet it is compared to the Ford Power Stroke and the Cummins in the Dodge. I test drove all 3 brands, and what won me over was the performance and power of the Duramax, as well as how much smoother the Allison Tranny shifted over the transmissions in the Dodge and Ford. The interior is the best of the 3.
So far, love it.

I bought my 08 SLT, Diesel on New Year's eve day, 08. I have put on 17,000 miles mixed mostly highway and suburban with a good bit of weekend warrior hunting and camping trips. I commute in this baby and my combined mileage is 15.7 over the last 9 months. That's with a cap on the back,and with 35 miles a day in hardcore SF Bay Area highway traffic hell. I don't tow but it will haul a back end load of hunting equipment, dogs and coolers full of meat. Honestly, I could use a lesser truck for most of what I do, but when I need to step up this truck takes it and keeps going. I can stick 3 dogs in the back of the cab, w. seats folded and they ride in comfort and one of them clocks in at 120lbs

If you are looking for a tough, dependable truck with a long life expectancy, this is what you are looking for.......... Let's start with the only negative. This truck is a two wheel drive and it does create some issues. If you hookup a trailer, you can get stuck on level ground in the grass, if it is wet. I am running high quality street tires, and they are great tires, but the low end torque is so good that it is difficult to get it moving on a wet, non-paved surface. Once it is moving, you are good. I am running a Bully Dog BDX programmer. It doesn't provide as much HP as my Triple Dog in my 2004 truck, but it still has plenty of get up and go. I have triple gauges on my pillow. With the BDX, I run a consent 5 psi of boost at cruising speeds, but when you need to go, it drops a gear and JUMPS to 30 to 35 psi. It's NOT an "out of the hole" dragster, but it will perform when you need it too. SLT package means all the creature comforts, and they are accommodating. They ride is firm to say the least, and it can be rough depending on the condition of the road. I have a rear air brag suspension (after-market), and it's probably time for new shocks. And there is the typical GM issues, cracks in the dash from the sun,etc. I am averaging 18mpg with the BDX chip. I can get that up to around 24mpg for just highway driving. I have added an auxillary full tank in the bed of the truck that let's me go about 1200 miles between fill ups, which is about 71 gallons of fuel between both tanks. And finally safety. I am weighing in around 7300lbs, which puts me at double the weight of most vehicles on the road today. Law of physics are on my side with regards to accidents.

My 2008 GMC diesel pickup has 41.000 miles and has been a good truck. However it will be 5 years old in December, and the body moulding on each side is loose and starting to fall off. The dealer said it is a common problem, but since it is out of warranty they would not fix it. I went to a body shop, and the person there said it is a common problem with that body style. He said a solution is to remove the moulding and glue and buff out the paint. His estimate was $240.00. I'm disgusted that this problem should occur on a $40,000 vehicle. I see 25 year old cars and trucks with the body moulding still intact. I'm disappointed GMC won't take care of the problem.

This is a great truck,This truck was used in the oil and gas industry and it has over 188,000 miles that I put on it.The truck has never been put in the shop for any major repairs.just regular service.Avarage 4000 to 5000 miles a month and it never left me on the side of the road.Tows like a beast! Used to pull loads of 7 to 9 thousand pounds over 600 miles @ 70 MPH.In fact I liked the truck so much when we got our new 2011 GMCs I bought this one from the owner.now she is retired but I would'nt hesitate to drive the truck anywhere.

Before buying this truck I owned a F250 V10. This truck was supposed to have 50 more hp and comparable torque but its lack of power is remarkable. My mpg is ok until I hook something behind it then its 5mpg... I have had no less than 20 warranty claims in 1 year. It absolutly can not handle any hitch weight without bottoming out. The sheet metal used to form the body is so thin the smallest bump and you have a dent. I really had high hopes that GM had a great truck but after the trans went out @ 6500 miles and many many other issues I'll admit I was wrong.. This pickup is fine for pulling your boat or cruising around but if you want a HD pickup do not buy this one.

I really can't say anything bad about my 08 single cab 2500 HD GMC Sierra. Reason being is bc I've owned it since brand new, the price was more than reasonable and when I test drove it for the first time it really felt like a truck. Its 6.0 gas with torsion bar front suspension so alittle ruff ride but all good bc its tuff and a ton of power out the whole and beyond. Its ten years later now and I still drive it every day for work and pleasure. Through the years I've put bigger tire,rims,tinted the windows,added stereo and leveled the front end. In ten years I've only had to replace one hub bearing other than I've just changed oil regularly,air filter ,3 batteries and 3 sets of tires and she just keeps going with 185.000miles. Also I've never changed brake pads witch blows my mind with all the towing I do. So to anyone that is thinking about purchasing this particular type of truck as long as it looks in decent shape I would highly recommend it.

This is my second GMC HD truck, and the imrpovements are too many to mention. This is by far, the best looking truck on the road. I'm averaging around 15 mpg around town and recently got 19 mpg on the highway going 85 with 2800lbs in the bed. GMC builds the best looking, most reliable, most fun to drive pick up trucks on the road.

I just bought a 2009 GM 2500 with the Duramax/Allison combo. Been with Ford all my driving life. So far, a great truck. Excellent power, very quiet and greater than 20 mpg on highway when unloaded. Seems tightly made. 2008 F250 previously; a great truck but physically too large for my needs. GMC offers similar towing performance, better mileage so far and a better ride in a physically smaller package-- with diesel power. Overall, I think the GMC offering is the top overall in the 2500/250 line for daily use/driving. I was not impressed with Dodge quality; my Ford was great but meant for wide open, all day towing. GMC offered the best package with the fewest comprimises. Very happy so far.
Great truck but a kidney blaster empty

I love this truck but when I am not towing or under load she will shake you on bad michigan roads. I decided to weigh it down a bit in the back and that has smoothed it out for sure. MPG is 12. 12 @ 74 towing the boat, 12 at 35 around town. I got 14 on the highway going 65 but that was hard to take for a 2mpg gain. Love the solid feel of the truck!

I purchased my 08 in October and now have 5000 miles on it. The fuel economy is around 16 in city and 18 on highway, but I am still in break-in period and expect improvement. Economy drops quickly north of 70 MPH. The Duramax and Allison are a great powerteam and while you can hear it shift, you cannot feel it. Interior on the SLT very well laid our and looks like it should be in a luxury car. The GM 100k warranty is a big plus. My only concern is the 26 gallon fuel tank is too small for hauling heavy trailers.
Well maintained engine took a crap at 60,000 miles

At 50,000 miles and 6 years old all auto door locks stopped working. At 60,000 miles lifter rockers failed and damaged cam shaft requiring a complete engine rebuild or replacement. I maintain my vehicles meticulously and have a toyota with over 300,000 miles on it. This truck is a huge disappointment and I will never buy a GM product again. Updated review at 80k miles all the other parts of the vehicle have begun to deteriorate. Seats, door handles remote mirror operation. I only keep it because it's paid for and I have 2 kids in college. It has not seen hard use. Goes off road and in the snow a few times a year on my fishing and hunting trips. I will reiterate that I will never buy a GM product again. Changing a burned out front headlight is a 2 hour affair. By a Toyota! It's worth a few extra bucks.

I have owned my gmc for 2 weeks now and i am glad to say i have made this decision. I have gotten the duramax and sllison combonation and it is unbelievable. I owned a 2002 chevrolet silverado 2500HD and needed to get a diesel. With this type of economy i figured that this is the time to act.We have gotten it for a respectable price. This truck is great to go through the dirt or just to drive around the city.
This is one super 3/4 ton truck

Bought an 08 Duramax 4x4 last month and just love the this truck. Ride is very predictable for a 3/4 ton, little harsh but if you wanted a smooth ride go with the 1/2 ton. The diesel has got a lot of horsepower. I love the quick acceleration this truck offers. I pull a trailer that goes about 6000 lbs. If you're looking for a truck to tow and gets generous fuel economy this is the truck.
Had to get rid of it

The GMC 2500HD is powerful, looks good, and can haul a ton of cargo without a problem. Has a stiff ride and a gas guzzler. The interior is somewhat simple and spartan but has nice accents, very roomy. The gas version has a nice roar to it and it picks up quite fast. The problem was the engine was too powerful for the tranny. The tranny went out a couple times and we had to move on. It was tough as nails otherwise.

I bought a 2011 GMC Sierra 3500 HD Diesel Z71 . I am very very happy with it performance and durability is wonderful. The Duramax is a gentle engine it will definitely do anything you want but just take care of it . My truck is a pleasure truck pulls my heavy fifth wheel very well and well balance. My only complain is the interior poorly designed and very cheap looking. I am proud of my GMC Sierra HD and I never regret buying it.

This is the first 3/4 ton truck I've ever owned and it is great. I've had Fords in the past and know people with both the F250 and F350. They've had too many problems for me to even consider a Ford. The GMC is built stout, and while the gas engine lacks the torque that the diesel engine has it is the perfect engine for someone who does not tow all of the time. It has plenty of get up and I'm getting around 14 MPG right now on the freeway at 75-80 MPH. Many of thr trucks I see pulling large trailers these days are GMC or Chevy, they must be doing something right. PS, while gas prices are high right now the purchase incentives are even higher, good time to buy a gas hog!
Great truck for what I paid
