Used 2005 GMC Sierra 2500HD Crew Cab Consumer Reviews

05' 6.6 V8

Very nice truck. Lots of power for pulling my 35 foot race trailer. Good on fuel about 21 highway 18 in town. I put the banks 6 gun chip in it. Very fast. Sounds good and has lots of power

GMC SIerra HD Duramax

This truck pulls a 30 foot RV travel trailer with absolutely no problem. Using the tow button helps slow everything down with ease. This truck is much more quieter than Dodge or Ford. It has lots of power and looks great, unlike it's competition.

Hi Oh Silver

i love my pickup, hauls my 40HP massey with bucket and brush hog like it's not even there. with banks big hoss bundle it hauls balls and doesn't think twice. awesome truck wouldn't give anything for it. it's dependable, and with all the mods it catches eyes everywhere i go. as of now, until ford puts out the 6.7L would only recommend a duramax. cummins is good but everything around it is crap and rides like a semi. duramax is king right now. i just can't say how much i love my pickup.

Good, but not great

This diesel was an upgrade from a gas Dodge RAM1500. Pulling a 7,000lb trailer now seems effortless. Turbocharger takes a long time to engage and gas mileage wasn't as good as I'd expected for a diesel- about 12.5 pulling trailer which is disappointing since over 20 without. Just had 3 injectors replaced under 100K Duramax warranty which I believe was a known problem in all GM diesels from 2002-2006. No recall, of course! No significant change in power or mileage with the new injectors. I hate that GM always adds a $95+ "diagnostic fee" for the computer hookup with any service. Also- computer's trip timer hasn't worked since purchase and the stereo speaker sound is absolutely awful.

Sierra Duramax/Allison

Fuel mileage is poor at best. Engine surge and hesitation. Driveability is very eratic. Vehicle runs hot, fan runs excessively. Tranny and engine temp gauges always show 210 or better. All this while running vehicle empty. When towing all of the above is off the charts. GM answer is that all is normal.

Speedometer Problems

I bought my Duramax Diesel 2500 Hd crew cab to pull a 36 foot fifth wheel. There is plenty of power; however, have had a few problems. The speedometer failed at about 60000 miles and had to be replaced. I have read that this is a common problem but there is a class action lawsuit and I plan to turn in my 478.00 receipt and hopefully get reimbutsed from GM. The engine light came on and paid to have the code read which was relatively meaningless but haven't had any more problems with that. I added a Superchip which is amazing how much perfromance improvement. Have heard that some people have burned up transmission with Superchip but I always reset to towsafe prior to pulling anything.

The good and the bad.

Purchased this truck on 5/26/05. Had it only three days and had to put it in the shop for automatic transmission repair. It was in the shop for four days. First gear went bad after only 500 miles. It doesn't turn as close as my old Yukon but it is a larger vehicle. The engine is powerful. I can't even feel my trailer. I like the looks. For an XLT it doesn't have some of the options I thought it would have. ie. lumbar seat, rear A/C. I really like the truck. I'm just disappointed with the transmission problem and the lask of service from the dealer. I'm just waiting for something else to break. It also is a little bumpy. Maybe that's normal.

Better than expected

So far this vehicle has exceded my expectations as to power and towing ability. I could not believe I was passing other vehicles as I was going up hill pulling a 20' trailer with a car inside the trailer. The gas mileage continues to improve as the vehicle breaks in. I love driving this vehicle and I am confident in its reliability.

It's OK, but check out the Dodge too

The '05 replaced my '03, both Duramax, and I have to say that I liked my '03 better. I don't know what GMC did between then and now, but whatever it was, I don't like it. I test drove a Dodge both times and thought that they rode too hard and the back seat was too small. On the other hand, is it worth $10 grand to get a GMC that also rides hard and has a slightly larger rear seat that I'm never going to ride in? To be sure, it's a nice car, but I'm starting to wonder if I shouldn't have bought the Dodge and put the $10 grand into my future Cessna fund. Come on GMC, for fifty grand you guys can do better! If you don't believe me look at your last 3 quarters sales numbers.

Camper caper

This GMC drives nice and handles very well on the highway. it has ample interior room for the grandkids and 3 adults, along with enough space for camping gear. When pulling a 28ft camper, it's pretty bouncy when empty. The back seat is split, and you can fold one completely down, or both, leaving a lot of space in the back and still room for 3 people in front with the fold down console. It has auto 4wheel drive to take over when roads are snowy, and plenty of power to drive next to the big boys. My wife even likes to drive it. I replaced the muffler with one that makes more noise.That was a mistake. At slower speeds that sound is evident in the cab. I like the truck, but it needs better gas mileage to really make it one to brag about!

What a fun beast!

Bought it new last month. I had a problem with the overflow tank leaking into the wiring harness and ruining a control module. 10 days in the shop and then the radio had to be replaced. Some gremlins in the electronics. If it is all fixed this will be my dream truck! I have the diesel. I am getting about 17mpg at 70-75 on the highway vs 14 for my 2002 Chevy K1500 w/ the 5.3 ltr. This thing will go straight up mountains without downshifting! What a beast! I was towing about 9k lbs behind the Chevy. I can't wait to hook "Max" up to the trailer! XM is nice for trips too. I have the buckets in front and the console encroaches on my leg when driving (I'm 6'4"), but you get used to it!

Love this truck

Love everything about this truck. Build quality is the best I have seen in years. Will pull a heavy trailer all day and it is easy to forget it is even behind you. Mine has the Duramax diesel and Allison transmission.

2005 GMC 2500HD SLE Crew Cab SB 4WD 6.6L

This 6.6L turbo with the 5 speed auto trans performs excellently whether driving empty or pulling a 30' RV. Interior is very plush (all the bells and whistles)and extremely quiet and comfortable on the road. The dash layout and field of vision behind the wheel is excellent. Added a bedrug and Pace Arrow bed-locker with power tail gate for security and improved MPG. Added ONKI brush guard for added protection from Colorado wildlife. This is a real truck for all occassions with added luxury and comfort!!! For '06 the manufacture has added 30 hp and 6 speed auto trans to an already outstanding rig.

GMC 2500HD Diesel-Automatic Crew LB

WOW....What a fantastic Truck! I have a 1995 FORD 250 Gas (70K Miles), and a 1994 GMC Gas (113K Miles). The 2005 GMC is comfortable enough and even with the longbed easy enough to drive and park that I leave the car in the garage and use the truck for work and play. When it comes to the work portion it is one powerful, competent truck. I wish the side mirrors were the size of Fords. All the manufacturers need to install a tie down hook in the front middle of the truck bed. Metal around rear wheels in truck bed is too thin in the GMC. GMC needs a radio mute button on the steering wheel. Needs additional LARGE cup holder for the driver in center consol. Cup holders too close together.

Nice truck

I love my truck so far it has a lot of power and it rides awesome. It is very comfortable and quiet inside. I would recommend it.

Nice truck

2500HD

Powerful and attractive. Very versatile.

Not Enough Professional Grade

Three days after purchase the truck was in the shop with transmission problems. It was there for four days leaving me without a business truck. I now have to take it back because the transmission is causing more problems. There is a thumping noise behind the dash that I can't locate. The ride is fine for a heavy duty truck. I really expected more from GMC. The seats are too narrow and I'm a short person. I traded in a 2000 Yukon. I will be looking at the 2007 Tundra next year.
