Knocking noise from beginning-dealer stated "cold startup"-wrong! manufacturer said not detrimental to engine-they had to replace my engine @ 25,000 miles-still knocking. Grinding in rear end at take off-had to replace my driveshaft-still grinding. My truck has been in 4 times for engine knocking and 5 times for rear end grinding. I'm now fighting with GM and BBB for a buy back-my truck qualifies under the lemon law-33 total days in shop so far. Will never buy another!!!

ABS brakes, do not stop. I was going 40mph and a flock of turkey was in the road, I put on my brakes and they went to the floor. Thank god that there was no oncoming traffic. Your brakes are there to stop you, not to go to the floor and travel about another 100 feet. I know there has been alot of complaints about these brakes, and my dealer said my brakes are fine. I guess it will take people getting killed in order for someone to adress this problem. Another problem>>> I have this clucking nosie in the rear of my truck, it sounds like the rear of the truck is going to fall off. A dealer stated that the drive-shaft yolk was dry, they removed drive-shaft and lubed yolk. Problem is worse than it was before. This is a 2001 brand new truck, I should not be having all these problems.
