Summary
What Edmunds.com says
Powerful drivetrains, classic exterior styling and unique options make the Sierra a pickup worth considering, but Fords new F-150 has it beat when it comes to interior design and overall refinement.
Pros
Roomy extended- and crew cab models, strong V8 engines, innovative features.
Cons
Spotty fit and finish, low-grade interior materials.
What's New for 2004
The big news for 2004 is the addition of an all-new light-duty 1500 Crew cab model with a five-and-a-half-foot bed that replaces last year's 1500HD model. The Work truck package is now available on all Sierras, while base models get standard cruise control along with a chrome grille, wheels and bumper. Other changes include newly designed 17-inch wheels on 4WD models, the deletion of the Professional package and a Quadrasteer package that is now available without additional trailering equipment.

OK so Far

Review
Bought used 117,000. Used a little oil and coolant would need irregular replenishing, odd. Every now and then a sticky lifter, then when I added Lucas to the oil all H--l broke loose, literally. Next oil change there was so much sludge in the sump the oil would not drained. Long story short, the sludge clogged the oil pump suction and w/o oil pressure things were not going to get any better. Found a used motor (100,000) miles, swapped out. Better engine, more power, no oil consumption, coolant OK. I'll probably drive this truck for another couple of years. I like it. I think the sludge was related to the coolant loss. As it was infiltrating the crank case and slowly evaporating out?

Maybe the aluminum head iron block matchup was the problem.
Best vehicle I've ever owned!

2004 GMC Sierra 1500 4dr Extended Cab Work Truck Rwd LB (5.3L 8cyl 4A)
Review
Absolutely, without a doubt the best truck I will ever own! 168,000 highway miles. Just replaced the original brakes at 167,000. Regular maintenance, oil changes, fluids, etc every 3 to 5K. No bells and whistles, this is a work truck, a darned good one! I get about 19-20 mpg on highway, I'll take it and not look back. Forget interior/exterior design...who cares? I wanted dependability. I got it. A great truck!

Review
I purchased my Sierra new, now have 49000 miles. Have had a couple problems but the dealer took prompt, and courtious care of my truck. Fun to drive, looks great gas mileage isn't bad either. I keep the oil changed, and just installed a K&N air filter and will see if my MPG improves. Overall I would buy another one.

Good looking truck

Maybe the rear window like Toyota has, have it open and close electrically.

2004 GMC Sierra 1500 2dr Regular Cab SLE Rwd SB (4.8L 8cyl 4A)
Review
The truck is more care like than truck. The suspension is soft and bottoms under heavy load. I've never attained the fuel economy declaired, only about 13 to 17 at best. It's been recalled once. The brakes have never been grippy enough. GM says the dashboard may go out at 70,000 miles and the stearing column center shaft went out twice. Now the left front wheel bearing is going out. The truck has not been abused!! I want to buy American but the quality needs to improve before that happens again! Most of the miles are highway miles with lite loads. The repairs have been very pricy. I purchased the truck new and there are only 39000 miles on it.
Favorite Features
Very comfortable seats. The 5.3 engine is the best part and provides plenty of power and torque. The tires will probably last 50,000 miles and it's good looking.
Suggested Improvements
The dashboard is cheap! The ride is too soft and their is not enough suspension under load. Way too many problems for the miles driven. Improve the durable quality. Make it tough and gritty. If you buy one figure on buying an extended warranty!
