This vehicle became a nightmare after about 10,000 miles. First the steering shaft failed ... ? That's right, the steering shaft! Next the instrument cluster had to be replaced since the low oil pressure warning kept chiming. It still chimes uncontrollably after replacing the oil pressure sending unit three times, the oil and filter five times (when it didn't need it), and get this ... they changed the oil pump and the thing still chimes at will! The truck rides like a tank. Now the steering gear box needs to be replaced. There are less than 85,000 miles on this pig!
Truly a masterpiece of "poor" engineering. 2004 sierra 2500 with a duramax diesel and Alison transmission. Had to replace the intermediate steering shaft the first year. The vehicle constantly looses prime and shuts down. Here's the kicker . The oil pressure gauge flutters and the annoying chime rings constantly indicating low oil pressure. The cluster panel has been changed twice, the oil pressure sending unit has been changed three times. They even changed the oil pump? Still, no fix. This truck has been a nightmare from day one!
Blocks the wind when parked in the driveway.
Lift up the radiator cap, drive a ford under it, then lower the cap.
I enjoy driving this truck! So far it stranded me once (due to a clip of some sort coming loose and the computer not knowing enough to send fuel to the engine) and that was at about 7k miles. OnStar answered quickly and got me a tow truck pronto! The dealer easily found the problem and my cost for all this was $0. The Bose system is very enjoyable. Acceleration and power are there when you need them. My 13MPG is lower than I expected, unfortunately.
Good power. Nice styling. Handling is good. Sound system is great. Fun to drive in traffic. Comfortable seating. Nice layout of controls.
2004 light duty Sierra 2500 4x4 crew cab w/6-1/2' box. A very comfortable, capable hauler of people and cargo. Rear seat area is huge. Seats are very comfortable. Ride is a little choppy unloaded, but that is to be expected. Smoother ride than GMC 2500 Heavy Duty. Tracks down the road very nicely. (This next comment is not a flame, I'm a truck guy, not a "brand guy") Much better than Ford 250, which tended to wander a bit - that may have been due to the more aggressive off- road tires on the Ford. With a bed cover in place, gas mileage went from 17.5 mpg highway to just over 18 mpg highway. Every bit helps. XM radio is worth every cent. On-Star is invaluable. Great dealer support during sale.
Seats are the most comfortable of any vehicle I've ever had (have had 17). XM radio/steering wheel controls are great. I don't listen to "regular" radio anymore. Kids enjoy the rear DVD and all the space. I like the layout of the cab and the way things fall to hand. Lots of storage in the front cab
A rear-sliding window, ala the "Tundra" that slides down into the rear bulkhead would be nice. Adjustable pedals would be a help for "inseam challenged". Exterior mirrors with "side-step" lights (like the 1500 series Chevy has) would be appreciated. Side pockets in rear doors would add more storage
