Used 2004 GMC Sierra 1500 Consumer Reviews
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?
bought the truck at 120k miles 4 years ago. today i have 205k on it as my daily driver to work and back (80mile round trip highway) and to the day all ive had to replace was an alternator. towed a boat for 3 years weighing aprox. 3800lbs with easy and stability. this truck is absolutely bullet proof and i would buy it again in a heart beat. note: i also just bought a 2015 sierra all terrain edition last December and to be honest i like driving my 2004 sierra better! absolutely great all around truck!!!
At about 53,900 miles, my 2004 5.3L developed a ticking noise. Turned out to be cracked cylinder heads. $3800 repair bill. I had it repaired and traded it for a brand new Tundra with 5.7L engine. No regrets.
excellent quality smooth ride should have got the 5.3 engine for more low end the 4.8 likes to rev and power comes on strong getting 20 plus miles per gallon with auto and 3.42 gears
This truck is extremely inpressive. After 15 years of driving a BMW I wanted something totally different and fun to drive - the Denali is all I hoped it would be in a full-size truck. People notice it and it turns heads. The QuadraSteer is an absolute must and is everything you hoped it would be - simply amazing. With dealer incentives and some negotiation, the Denali can be had for around $34,600 - this makes it an incredible value. If you're in the market for a top-of-the-line full size truck, the Sierra Denali should be at the top of your list. A great truck.
