Almost Perfect!

Before purchasing this vehicle I researched everything about it to the inth degree. I ended up trying to decide b/t the 08 Tundra and the 08 Sierra. I test drove the Tundra and liked it, immediatly following I went and test drove the Sierra and fell in love. MPG is as advertised. I can feel the v8 switch to 4cyl but no one else in the veh can, not a bid geal. My 2 dislikes: the brakes and transmission. Simply put, replace the rear drums with the Tundra's disc brakes and replace the 4 speed tranny with a 5 or 6 speed and you have the perfect truck! The 5.3 (w the 4 speed) feels less beefy than you would expect. All in all, I am extremely pleased. I am now a GM man for life.

Immediately drove 2 WD truck (17" tires) to central OH from central FL - 20.2 mpg @ cruise set mostly 75 mph. Returned to FL w/bass boat in tow 15-17 mpg. Ride is super w/effortless handling. Plenty of power with 5.3 engine. I wanted a truck with car type ride. That's why I got 2 WD with 17" rims.

Cracked Dash and AFM Lifters

Just after the power train warranty expires my AFM lifter sticks. $3000 shop bill later and some internet research I know to watch my oil level like a hawk and never purchase another GM. Also the Massive cracks in my dash remind me of 80's GM. Its nice to see them bringing back the materials from their 80's cars. Don't buy one of these trucks. Buy new and dump them when out of warranty.

Great Truck

I have over 33K on my truck and use it for city and long distance driving. The truck rides and drives beautifully. I have a bad back and I drove an '08 Ford F150, Toyota Tundra, and Chevy (has less comfortable seats, go figure). The GMC out drove them all. I've used it to haul everything and it does it without a problem. I have the 5.3L engine and get 16 in the city and 18 - 20 on the highway driving 8 - 9 mph over the speed limit. Problems I've had with the truck: 2 of the 4 electric door locks went bad within 18 months. Dealership replaced them all to ensure no other issues. I've had great service at two dealerships I use. I'd buy another!

2008 GMC Sierra 1500 Denali 4dr Crew Cab AWD 5.8 ft. SB (6.2L 8cyl 6A)
1 of 5 people found this review helpful

No way this truck has 403hp. Had two different 06 Titan trucks that would leave this thing in the dust. Also, the Titans would out tow the Denali. The Bose radio system is whimmpy compared to other trucks and cars I have owned. Handling is so-so. No standard step rails or sprayed in bed liner. Come on GMC this is your top of the line? Get real. I guess this will be the last GMC I will buy.
