I had the drive shaft slip yoke lubricated 6 times before I could convince the GM Tech Rep that there was a problem. I finally got them to replace the slip yoke. When the truck had approximately 20,000 miles on it, I brought it in for an oil change, and the dealer told me that I complained about the throttle body sticking and they replaced it under warranty. I have since had that throttle body replaced at 50,000 miles.
The biggest problem I had was... 41,000 miles, the oil cooler in my radiator developed a leak and drained my transmission of Automatic trans fluid. This in turn, caused the transmission to eat itself. Fortunately, I had purchased the extended warranty because I have been complaining about piston slap since I bought the truck. Otherwise GM was going to make me pay for half the repairs. The dealer sent my truck out to a trans shop for inspection, and three weeks later I got it back with a completely rebuilt transmission and a new radiator. The next day I brought it back because of extremely hard shifting and a trans service light, to have the valve body replaced. Then I brought it back again because they forgot to hook up the vacuum line to my front differential, giving me a service 4WD light.
After all of that, and I am still complaining about hard shifting, I made GM give me a 100,000 mile power train warranty.
I have also had the front break calipers lubricated because of the brakes grabbing.
At 52,000 had the parking break shoes replaced at dealers expense.
Aside from the problems I have had with the truck, I still love it.
The engine has balls and it sounds great even with the stock exhaust and intake.
I am thankful for the auto 4WD on my pushbutton transfer case because the rear does get loose on wet roads.
Besides, hell will freeze over before I buy a Toy-ota, and I'd rather push my Sierra than drive a Fix or Repair Daily or a Dodge.
This person was obviously not a mechanic. You would never have to lube brake calipers because the pistons inside the caliper are self lubricating as in any type of brake caliper. I would dismiss most of his comments referring to the mechanical reliability seeing how he let his transmission run out of fluid.
Actually I believe he means they lubed the caliper slides which is a common thing, if this is not done the calipers will stick not the caliper pistons. Both need to move free!
I have a 2000 GMC Sierra with about 34000 miles on it. I recently began experiencing a pull to the right when I depressed the brake pedal. It is not severe, but very annoying. I don't know the cause, but plan to have it checked tomorrow. It has 4WD.
I have a 2000 gmc z71 and I had the same problem with pulling to the right and I took it to the dealer and they told me that there was a flat spot on the tire. they rotated the tires and its been OK every since.
I bought a 2000 GMC Sierra last year, and since then have had problems. There is one problem, in particular, that no one seems to know the cause of, or if there even is a problem (they think it is in my head. I had put a bigger tire on it... (changed my 245/75/16 to 265/75/16 and had no problems. I have had the tires on it for about 6 months, and recently noticed that it is shifting weird. It seems to be shifting up gears too early. Especially while driving up large hills, it shifts up gears, and I have to put it to the floor to get it to move. This is getting costly. I have had all the tune ups done, with a change of tranny fluid, pan and filter... did not make any change. Does anyone have any idea as to what the problem is?
To the people that have the trucks that pull right what GM vehicle doesn't it is one of the quirks of the brand. To the person with the shifting problem of being to early it is caused from the oversized tires you need your computer recalibrated either at the dealer or get a plug in tuner which does the same plus gives you the option of power upgrade.
I have a 2000 GMC Z71 and have noticed the sticking throttle. I have found this is caused by a dirty throttle body (hardened oil residue on the inner surface). I simply clean the inside of the throttle body regularly with a rag soaked in carb cleaner. Works good. I would like to know where to get the reprogrammer as I also have the high shifting truck which is annoying going up hills. Overall nice truck, but gas is getting expensive these days.
Well I have a 2000 and this is the first time I have had problem with it. My rear end differential needs to be replaced. I have the piston slap too, but all in all I still think it is a great truck. I have 123500 miles and this is the first problem. Late last year I took a trip and I got 24 mpg with 5.3 and 373 rear end. I will always buy a GMC.
There is a wealth of both information and misinformation in this review, and its comments.
Brake pads never need lubricated. The part commonly referred to as "sliders" should be lubricated during brake pad replacement, but often is not.
The reference to transmission shifting too early is, as earlier noted, due to installing larger tires, but not getting the computer recalibrated to match.
I am surprised at the number of people on here that believe normal wear items (tires, brakes, etc) should last over 50,000 miles. If you get that much out of them, consider yourself lucky.
I own a 2000 Z-71 with 53000Kms and when the temperature is around 0deg.C it sounds as if there is no oil getting to the valves, it sounds like a diesel engine. This happens only when I start the engine cold and disappears after having run for about a minute. I've checked the oil level and it's at the full mark. Has anyone experienced this before? Also when I activated the auto wheel drive last week nothing happened it just wouldn't engage in auto. I was going to bring it to the dealership, but it works fine now??? Will it do this while I need it in mid winter, I hope not. Did this happen to any of you?
Thanks

I HAVE A '99,2500 sierra basic truck. I work construction so I HAVE 8 PLY TIRES I GET 70 K OR SO OUT OF THEM... MY ABS WENT OUT LIKE 30 MILES OUT OF Warranty ON MY LEASE.. I CALLED BS AT THE DEALER AND THEY REPLACED IT FOR 100$..OK..NOW BESIDES A GAS BEAST,, IT WANTS TO STALL IN GEAR, It's a AUTOMATIC, AT STOPS.. I HAVE TO PUT IT INTO NEUTRAL TO KEEP IT FROM STALLING.. I TOOK IT TO A SHOP AND THEY TOLD ME IT NEEDED A TUNE UP... WHAT EVER...BIG BUCK TUNE UP AND IT DOES THE SAME THING... IS THERE SOME SORT OF IDLE COMPONENT THAT A CARPENTER CAN INSTALL??? HELP.
To the Nov 20th post of the Z-71 with 50K miles, I-know this is late, but, your truck has vacuum lines that operate your 4x4. When it gets real cold sometimes there is moisture in the lines and it freezes causing the 4x4 not to actuate, when it happens try putting your truck in a garage or somewhere warm for a few hours to let it thaw. That has happened to me more than once.
I got a 99 and I love it only had 1 problem since I had it and it was the cat coverter oddly... and about the guy saying it stalls at a stop... check torque converter..
I have a 2000 GMC Z-71 4X4. I am having problems with the truck wanting to stall when I come to a stop. I am also having problems with starting, not all the time, but often. By starting, I mean that sometimes it takes a couple of times for the ignition to turn over. Any thoughts??
I own a 1997 GM Z71,I love the truck it has great power for passing out on the highways. I have how ever had many problems, I have replaced the fuel pump three times, once on a search and rescue 40 km from the nearest town and another three months later. I have replaced the alternator four times. I was told by the parts store that the alternator I have been given is the only one that is available for my truck. Does anyone no of a good enough alternator that would last more than four or five months or is there a problem I am not aware of? The battery has been replaced because they told me that the problem was that the it was drawing to much power for the alternator to produce. The truck has about 187000 km. It has seen many bush miles and have found no other truck to match its performance in the bush. On the other hand my wife is ready to pitch it.
