2008 GMC Sierra 2500HD Crew Cab SLE2 4dr Crew Cab 4WD LB (6.0L 8cyl 6A)


Review

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.


Best Features

Towing and hauling capabilities, large front grille, comfortable leather seats, heated back and seat pads, 6 speed Allison, 33 gallon tank for long trips (MA to NC on a full tank!), OnStar, XM radio and steering wheel controls


Worst Features

Lacks armrest in the seats. Fuel mileage should be better. REGEN drinks the fuel down fast. These bumpers are very thin! Power mirrors and the paint needs improvement

Review

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.


Best Features

I love the room and comfort. The info center is still a great feature and keeps me aware of temps, mileage, tire pressure, etc. I love the OnStar and would recommend it.


Worst Features

Dump the XM radio.

Review

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.


Best Features

The new outside style and interior are my favorites. Dual electric seats up front is great and large trailer mirrors work great. I think GM hit a home run with this truck. I get about 17 MPG on the highway


Worst Features

Fold down arm rest for the front seats, and extension in the sun visors would be great.

Review

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.


Best Features

Exterior body style. Interior appointment


Worst Features

Transmission. Delay in shifting. Interior noise due to shifting of plastic and weatherstripping around doors. Horrible ride when transporting family around town.

Review

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.


Best Features

The info center and the rear seat room are real improvements.


Worst Features

Standard under the rear seat compartment would be great, to keep paper towels and small items in place.
