I got this truck used with 80000. It had a bad intake gasket and got replaced. Engine has not given me any issues since. z71 4x4 is pretty dang nice, its hard to get this this thing stuck in the mud. Issue with the motor in the transfer case... but never stopped working (says service yada yada. been checked. not a big issue). basic maintenance and think I can give this vehicle to my kids (not soon either). GMC seems like a good truck with some quirks, but solid and runs when you need it. The 5.3 has some passing power, and tows like a champ. If you like your girls a little high maintenance, go on and get it. If not, then buy an old truck and forget about all the gadgets. good luck.
Bought new in late 2002 truck has been average for comfort and mileage is good. Reliability is not good to many small issue my truck only has 60k and have replaced both front wheel bearings, replaced two power window motors, had to replace sensor for ABS brakes, steering gear box and now the cluster is going bad. GM know the cluster unit is an issue but refused to help on the repair cost. I think I am going to look at the Toyota Tundra for my next truck. GM just need to have a better warranty on the little things that are always going bad on their vechiles.
Bought truck new in 03,I have over 140K and have not had to spend $1 on repairs. Replace fluids and do proper maintenance and it runs as good as the day I bought it.Would like to buy a new truck but cannot justify replacing it as it is so reliable. I drive a lot of highway miles and get almost 19 MPG if I keep it around 70 MPH.
Purchased this truck with 48K and am very surprised of the quality of this truck. Being five years old I expected the suspension to maybe a tad loose or at the very least expected to hear cabin rattles and squeaks. Nothing; feels like a brand new truck. I have the SLT with the Bose and heated leather buckets. You never want to get out of it! Looked at all the other manufacturers and now know without question, I made the right choice.
When I first purchased this truck I thought it was the smothest riding and best handling 4x4 I had ever driven. (Wife has purchased a Yukon 4x4 and it is even smoother riding) It has spent a good deal of time off road. I do not get rough or overly abusive, mostly steep hills, sand, mud under 6-8 inches and a little rock crawling. If yours does not have the locking rear differential it is worth the money. I am sure it has saved me more in tow services than it costs to have installed. I have not had any serious mechanical failures, I did have a u- joint start chirping on me after a week in the hills of western South Dakota. The truck has about 50,000 miles on it and gets serviced regularly.
