	Engine knocking- described by gmc as an oil cavitation no known fix and only certain trucks are having the problem
SEAT BELTS - FRONT - RETRACTOR
08/01/2002		2	06/01/2001
	The passenger side front seat belt tightens up continuously when worn. as a consequence, the belt is useless and unusable. i have attempted to get it repaired 3 times at two different dealerships to no avail. i know of two othe vehicles with the same problem. the service manager at the dealership says that his vehicle has the same problem. the manufacturer tells me there is no fix available. this is a serious safety deficeiency and should be addressed on this very high volume vehicle (suburban, denali, tahoe etc..)
SERVICE BRAKES, HYDRAULIC - ANTILOCK
04/11/2001
	Brake system fails to engage for approximately 5 to 10 seconds after pressure has been applied to the pedal. consumer has taken vehicle into dealership three times, and was told there was nothing wrong with brake system. consumer recently rearended another vehicle while traveling on highway 70 mph when vehicle ahead of consumer's vehicle started slowing down, brakes failed to engage. no injuries, no police report, cosmetic damage to the vehicle. please provide any additional information/attachments. *ak

	Consumer purchased a vehicle that was 3 inches taller than safety requirement. when driving approximately 30 mph vehicle started to shake. consumer was pulled over several times because vehicle was too tall. vehicle was finally impounded by highway patrol due to safety standards. *ak
TIRES
			05/01/2001
	My pickup had a recall (#01021) to change the recommended air pressure . the pressure went from 55psi in the front and 80 psi in the rear to 35 psi on all tires. i contacted firestone and they told me this pressure was unsafe and those tires should have no less than 58psi. the new sticker makes no mention of increasing the air pressure if a load is being carried. the rgvw for that truck is 6084 lbs, and the tires are each rated to carry 3042 lbs at 80 psi. a lower air pressure drastically reduces the load bearing capability of the tire, which is not accounted for by gmc. my dealer agrees that the pressure is to low and has recommended i remove the tag and use the previous recommended pressure. i and the dealer have contacted gmc and can get no answer on why they changed the pressure and whether it is safe. i am concerned that other owners will not realize there is a possible safety concern with operating these tires at such a low psi. *ak (tiresize: lt245/75)
