Best Truck I ever owned!

Review

I have built quite a few cars and trucks over the years, this by far out performs them in an all around sense. I got a pretty basic truck for my buisness so that's why comfort is a marked low. My only complaints are that I didn't go bigger with an extended or crew cab, and we need the 6 speed in the basic trucks too. The motor is the most impressive part of this truck. I have a tool box and tonneau, and now acheive up to 22 mpg. The six speed wouldn't work here. My friends Scion TC only get 25-27 mpg average so I'm very very happy.

Favorite Features

The 4.8 liter Vortec. 300 horse, and 22 mpg. And to think I almost got the Colorado with 1/2 the bed size.

Suggested Improvements

Introduce power windows, and door locks to all trim levels. I'm 5'9" AND can not reach the other door unless I walk around. Also the 6 speed. The gears can get a bit wide when loaded up with 1500 pounds. I'll be your best friend GMC.

Review

This truck drives great! I have an 03 Yukon that gets about the same mileage without cutting 4 cylinders off so that doesn't seem to be worth much. It has developed a squeak in the front end the past few days like a dry ball joint but the dealership isn't open on the weekend so I will get it there Monday, pretty annoying for a truck with 3000 miles. I have always loved GMC'S so I love this one too, it looks great and other than the squeak has been great. There is a lot of air noise from the doors that is annoying with the radio off. There are plenty of power ports for devices in the front and back and even one in the console!

Favorite Features

Rear extended cab doors open all the way open to the side of the truck and rear windows roll down which is really nice. The All Terrain package I got has 18" chrome wheels that look awesome and many people have commented on them, it also has a chrome grille. Love the XM radio. Four wheel drive!

Suggested Improvements

I put a Ranch fiberglass bed cover on the bed that is great, should be an option. Grease front end before letting leave factory. Improve OnStar service area if going to equip vehicles with it. Make doors more airtight.

Review

I have never owned a truck before, but I will be moving my son to college and am planning some large home renovations. I bought this truck because dealers are making incredible deals on full-size trucks. A 2.5 ton vehicle with a 315hp engine that gets 15mpg around town is not bad in my opinion. Mine is a 4x2 because I am always on asphalt and it rarely snows in SE Virginia. One tip: Stabilitrak comes with traction control. So consider this option with a 2WD if you want a lower sticker and really don't want/need the extra maintenance and fuel comsumption of a 4WD. This vehicle handles well and is smooth and quiet. It reminds me of a 1977 Lincoln Town Car, only it handles much better.

Favorite Features

The remote start makes sure I don't get into a hot vehicle. It also defrosts in the winter. No windshield scraping necessary.

Suggested Improvements

The extra-cost aluminum wheels are a real pain to clean with all of their nooks and crannys.

I completely love this truck. I modified this truck and added an additional 35 hp to the existing 403, wow! Need I say more! Added side steps 5" oval, bed cover with rear spoiler and lite, complete tint. Modified exaust for deeper purr, added air intake, Customized GMC Logo cyrstalized. Black it out completely, changed door handles to black got rid of chrome strip, added OMEX 6000K halogen kit, got rid of the orange on front head light assembly, changed tailpipe all black 5" oval, sits on 26" black rims, with a lowered supension kit 2"f 5"b, looks mighty damm good! Wish I could post a picture. This is what a real truck should look like, love it, love it, love it.

Favorite Features

Power, and looks

Suggested Improvements

Gas mileage but you cant ask for miracles. Diesel option would of been nice on the Denali!

2008 GMC Sierra 1500 Denali 4dr Crew Cab AWD 5.8 ft. SB (6.2L 8cyl 6A)

Review

Very impressed with this vehicle. Sold my 175K mile Sierra and due to its excellent performance, I'm sold on GMC. The Denali drives and handles great. 18mpg hwy and 16.4 in town. Not bad for a 6.2 ltr V8. My previous 4.8 ltr V8 only beat that by 1mpg! My vehicle came loaded w/options and couldn't pass it up for $38.5K. With gas prices I think they are really having to come down on these things. Very quiet ride on the highway and around town. It does need more storage compartments/center console organizer. I would rather the center console open from the side rather than front. It's somewhat awkward and has a rather flimsy spring hinge.

Favorite Features

Sunroof, DVD sytem (kids), backup sensors, folding mirrors, heated mirrors,remote start, but most of all the impressive look, engine growl, and driving feel! A wonderful machine!

Suggested Improvements

Engine needs Flex-fuel capability. Not too crazy about the nav system. I think GMC should contract w/Garmin and use their technology, much more user friendly. I live in the country and the Nav system typically won't use smaller roads even though distance is cut by half. Poor route recalculation

Review

I just bought this truck, it now has about 6,000m on it. I LOVE it. Lots of power, tows great, very comfortable. Fuel economy stinks but what do you expect with a 6.2L V8? I love the lines of the body and the interior has plenty of buttons! I really don't have any complaints, although for the money i should get a backup camera... Oh ya, and it's all time 4-wheel drive, i don't like that at all! NO burnouts!

Favorite Features

Exterior looks, nice wheels, power

Suggested Improvements

Be able to turn 4-wheel drive off, backup camera.

Review

This truck is great, the wide stance make you feel safe. The handling is great, there is hardly any roal in the suspension when cornering. Believe it or not I jumped my new truck 1 week after I got it. But not purposly. When I did so the landing hurt but the truck was fine. The balance was tweeked but I checked it out and nothing was broke or bent. It drives the same as before.

Favorite Features

I love the remote start. The display for the XM radio is great and easy to read. And the aux pre out in the front of the radio is nice.

Suggested Improvements

It needs a 5 or 6 speed trany. The 5.3 just feels like it strugles when your foot is not in it hard. The bed needs to be at least 2" longer. Getting an ATV in the back with the tailgate closed is a problem. One day GM should cosider making their wheelwells rounder for larger wider tires.

Review

Bought 3 months ago; now have +10K mi's. Love it. Been 30yr Ford guy. 1st GM truck ever considered. Bought the wife an 08 HHR liked it & got me to consider a GM again. Traded my 03 F2504dr 4x4 diesel (loved it) had +180k mi's;still miss the big 600#ft torq. Dealer offered me a 2-day GMC test drive! Hated the "luxury" dash; reminded me of dad's old gran marque, yuk. Wanted more lux but that dash was a deal-brkr. Added SLE pref + NFL pkg & leather/sunroof. Passengers can't but I can notice fr V4 to V8 pwr surge. No tailgate lock!? Will buy one. Has 3.42 rr gear; hard accel into 2nd gear causes rpm's to fall out of pwr-band then comes up. Ctr of hood vibrates continually while driving.

Favorite Features

20" wh's, XM, Bold grill & fender "shoulders", adj peddles, rr park assist, stereo ctls on steering wheel, 2 glove boxes, under seat lockable storeage, dashboard guages. Mileage improving too +18 routinely. 3- blink blinker,Tire Press Monitor, garage dr openr programed 1st try! Exh note, DIC &ESC std

Suggested Improvements

Left fingers accidently "set" cruise ctl. Avg MPG counter too optimistic by 1 mpg. Jouncy ride compared to my F250 4dr 4wd diesel. Needs coin holder & sun visors long enuf to cover side windows. Spray in liner. Bought Undercvr tonneau- nice! Dr's interior door locaton latch non-intuitive 1st 2 months

Review

Coming from a Honda Civic the Sierra 1500 feels like a monster. What a dream to drive. I actually enjoy driving to work now. One of the first things I noticed was how quiet the ride is. With the windows up road noise is virtually none existent. I've been getting around 16.6mpg with all around driving. I suspect that will go up as the motor breaks in, but hey if you're looking for fuel economy buy a prius and just hope that someone in a 1500 doesn't hit you. I highly recommend getting the remote start option. I always start the truck a few minutes before I leave and it either turns on the heater or AC depending on the inside temp of the truck. Nothing like hoping into the perfect climate.

Favorite Features

The remote start is a most have. The leather seats are really nice and the 170 degree swing of the rear doors is key. Also having rear windows that roll down is nice.

Suggested Improvements

Standard rear disc brakes would be nice. All and all this is a great truck and I am very happy with it.

Review

First & last GMC truck(2008 SLE 4- Wheel Drive, 5.3 engine). I just traded this truck with 1900 miles on it. The truck had vibrations in the front and passenger door. 3 trips and 14 days in the dealership did not solve the problem. My personal mechanic said the problem was in the powertrain. I gave up and took a loss. I told this story to General Motors and have not even had a reply! Fool Me Once!

Exterior Looks

Suggested Improvements

Quality control or lack of.
