After taking my truck in for a complete fuel system cleaning service, I started to hear a rattling sound every time I turned on the ac. I took it back to the dealership (capital Chevrolet in montgomery, Alabama) thinking that they forgot to tighten up something -- only to find out I need a new ac compressor. I overheard the service technician say that there is a bulletin out on this. I called the 800# but have not gotten a response in over a week. I was told by 2 independent service mechanics that this is a major problem with that the Suburban and Tahoe!!! December 2002. Attempted to stop suddenly. Brakes locked and the car went into a terrible skid. Was unable to control the brakes by pumping. The car eventually skidded off the road into a ditch causing tremendous front-end damage. Air bags never deployed. Car was going about 25 miles/hour when brakes were applied.

While driving at highway speeds power steering and brakes fail, resulting loss of power steering and brakes simultaneously. This is due to the failure of the power assist and power steering pump. This is the second time these components have been replaced. This was first noticed and replaced in January 2002. The second time occurred in February 2003. On 6/11/2003 the vehicle again showed indications of a problem with the brakes and steering. The brake pedal began to pulsate, and a high-pitched whine could be heard when turning the steering wheel. The vehicle also experiences problems when braking over rough road, such as rumble strips. As this is a third problem with these critical components, the safety of this vehicle is in question. The last visit to the dealer was said to be loose bolts on the power steering gear box. The power assist design is a known problem with this vehicle. I have spoken with service writers, service managers and have read other reports concerning other incidents like I experienced with this vehicle.

There was an engine knocking problem. The dealer and the manufacturer were contacted. The consumer was given a letter that certified that the manufacturer was aware of this problem, and the vehicle was okay to drive. The consumer disagreed, and felt the vehicle was not safe. There was a noise, rubbing sound when the brakes were applied. There were knocks during the initial start of the day, and the window was noisy while operating as the regulator cable was loose.
