Overview & Reviews

Quadrasteer is no longer available on 2WD models, standard wheel sizes have been bumped up to 17 inches and, on extended and crew cab models, a power sunroof that includes HomeLink and a deluxe overhead console in now optional. GMC takes a step backward this year with the return of rear drum brakes, as opposed to last year's four-wheel disc setup. Big changes for the Denali this year -- Quadrasteer is no longer available, and the Denali is now a crew cab model only. A gasoline/electric hybrid model is also introduced this year. Basically a "mild" hybrid, the system provides no power boost, but does allow for automatic engine startup and shutdown at stops. This truck also comes with four 120-volt AC power outlets and is the only Silverado with rear disc brakes this year. The hybrid truck is only available in Western states and Florida.

• Roomy extended and crew cab models, strong V8 engines, innovative features, slick hybrid electric option.

• Lags the competition in terms or refinement and power, spotty fit and finish, low-grade interior materials.

  Opinionated Mechanic - 2005 GMC Sierra 1500
  By Branden - July 13 - 6:06 am

  Performance is important to me. The engine pulls hard at higher RPM but lacks low end torque. I have a 3.42 rear gear ratio. If youre using the truck for trips and highway use, thats a perfect ratio. If you want to do towing or be quick between red lights I would get a 3.73 or 4.10 ratio to make up for the lack in low end power. The transmission performs Okay if youre looking for smooth shifts. I prefer a firm shift which you dont get, even in the towing mode. Towing mode just runs out each gear to a higher RPM. Which is good for towing. They advertise a locking differential. Its not a true locker like GM and Ford used in muscle cars. This unit sends power to the wheel with the most traction.

  05 Denali - 2005 GMC Sierra 1500
  By Mike - June 26 - 9:00 pm

  I have owned several GM trucks and one Ford - this is definitely the best Ive owned. The acceleration is very good, the truck handles well, transmission shifts are smooth, and it is very quiet and comfortable for a pickup. Pulls a 6,000# boat like a dream. My only minor complaint is a slightly mushy brake pedal feel. It seems that you have to apply more pressure than on other trucks Ive driven. Overall, a very nice truck, and with the current GM offer, a good value in my opinion.

  the defective casteck heads in my 5.3 leak coolant. this causes what sounds like bad lifter. know what heads are in your 5.3 before you buy, otherwise you could wind up with truck with repairs more than its value.

  If it onlly could turn better!! - 2005 GMC Sierra 1500

  This is as comfortable as any car I have owned. It has decent gas mileage and enough power for most needs (5.3L).

  I have a GMC Sierra I bought second-hand with the optional GFX package. I really like the extra exterior/interior features such as two tone paint, stripe on the side, carbon fibre dash, white gauges etc. At first the 4WD did not work, however after a quick cleaning of the connection from the wire bundle to the solenoid on the side of the transfer case, I have had no problems. It came with the 5.3L aluminum block engine and pulls quite hard. Tow/Haul mode is great for uphill towing. The cab had an annoying grinding noise which was quickly remedied with some hockey tape on the cab door latches. Overall, a great work truck and daily driver.

  Mostly Happy - 2005 GMC Sierra 1500
  By RMcGee - February 1 - 10:50 pm

  As soon as I saw this vehicle I loved it. Victory Red w/ GMC 20" wheels. I am on my 3rd year and just under 36k miles. I have pulled my 22 boat to the Ozarks which is around 300 miles each way through some hilly country. The truck shifts down a lot to keep up the RPMs. The interior seems a little on the cheap side & reminds me of some Mattel toys I had as a kid. I did have the intermediate shaft in the steering fixed at 25k miles. Now that my warranty is up my check engine light is on and I guess the vaccum canister needs replaced which is $500(for plastic). Overall I love the truck and use it for everything from towing to hauling. I just wish the standard warranty was 100k.

  Happy so far - 2005 GMC Sierra 1500
  By Tom is Happy - January 7 - 12:33 pm

  Love this truck so far.. 7 months old no problems yet. Added an ARE cap over bed and love it, got the Suburban look minus the $15,000 difference in price. Fits the car seats easily and the adults even easier. Havent done a long trip yet but Summer is aproaching and a looking forward to the drive. (Even if the gas costs $4.00 per gal.) Wish I could get better gas mileage but its a full size truck not a Honda CRV, which is easy to remember when I load it to the hilt , shopping or constructing, get it all in. Only things added was remote starter and sliding rear window (vital) which were negotiated during sale.
