I have driven 119000 km construction
usage. Only major problem: Clunking
transmission. Cost 2000 to fix. GM
paid half. Repair was done at about
70000km, just beyond warranty. OK
since. If you notice any tranny
clunk, insist dealer fix under
warranty. Don't wait around like I
did. 6 litre engine is flawless.
Front end has never been touched-still
tracks straight. I just did front
brakes for the first time. The old
pads were fine, but I rplaced them
anyway. My 95 GMC needed front brakes
every 40000 km, my '90 Suburban-every
25000km. I will buy GMC again.
I like every thing about this truck except that the gas guage has never worked properly.The transmision temperture guage also does not work. I took it in to the dealership for repairs and they told me they had to replace the instrument cluster and they did not guarantee that it would solve the problem. A co-worker had the same problem with his. I expect better reliability then this from a 2000 year model.
