At 50,000 miles and 6 years old all auto door locks stopped working. At 60,000 miles lifter rockers failed and damaged cam shaft requiring a complete engine rebuild or replacement. I maintain my vehicles meticulously and have a toyota with over 300,000 miles on it. This truck is a huge disappointment and I will never buy a GM product again.
The GMC 2500HD is powerful, looks good, and can haul a ton of cargo without a problem. Has a stiff ride and it's a helluva gas guzzler. The interior is somewhat simple and spartan but has nice accents, very roomy. The gas version has a nice roar to it and it would pick up quite fast.
The problem was the engine was too powerful for the tranny. The tranny screwed up a couple of times and we had to move on. I miss it though. That sucker was tough as nails otherwise.
My 2008 GMC diesel pickup has 41.000 miles and has been a good truck. However it will be 5 years old in December, and the body moulding on each side is loose and starting to fall off. The dealer said it is a common problem, but since it is out of warranty they would not fix it. I went to a body shop, and the person there said it is a common problem with that body style. He said a solution is to remove the moulding and glue and buff out the paint. His estimate was $240.00. I'm disgusted that this problem should occur on a $40,000 vehicle. I see 25 year old cars and trucks with the body moulding still intact. I'm disappointed GMC won't take care of the problem.
The truck does a great job job of pulling our 3 horse gooseneck trailer. I also like the manual mode on the allison transmission.
Use different glue or an alternative method of attaching body moulding.

This is a great truck,This truck was used in the oil and gas industry and it has over 188,000 miles that I put on it.The truck has never been put in the shop for any major repairs.just regular service.Avarage 4000 to 5000 miles a month and it never left me on the side of the road.Tows like a beast! Used to pull loads of 7 to 9 thousand pounds over 600 miles @ 70 MPH.In fact I liked the truck so much when we got our new 2011 GMCs I bought this one from the owner.now she is retired but I would'nt hesitate to drive the truck anywhere.
I bought this truck from a local used car dealer. I drive this truck mostly through the mountains of southwestern PA hauling my travel trailer. I previously owned a 2005 F250 diesel. There is absolutely no comparison between the two trucks. This GMC outperforms the ford in every way possible. I never thought I would say this considering my grandfather, my father, and I have been ford guys our entire lives but the proof is in the way the truck drives, handles, pulls, and the reliability I have experienced with this truck. I have driven this truck for more than 15,000 miles and overall I am completely satisfied. I have to say that this is by far the best truck I ever owned.
The comfort, the drive, and most of all the reliability. The Allison Transmission.
A handle on the drivers side for getting in and out of the truck. Better hose for the transmission, I'm tired of replacing them.
