This bulletin is being revised to address hoses used to service 1991-2006 vehicles. Dealers who ordered these hoses for service are identified in the
attachment contained in the Administrative Message (U.S.) or Dealer Communication (Canada).
Condition
General Motors has decided that a defect, which relates to motor vehicle safety, exists in certain 2005 Chevrolet Corvette, Silverado; GMC Sierra; and
2006 Buick Rainier; Cadillac Escalade, Chevrolet Corvette, Express, Silverado, Tahoe, TrailBlazer, TrailBlazer EXT; GMC Envoy, Envoy XL, Savana,
Sierra, Yukon; and HUMMER H2 vehicles. Some of these vehicles may have been built with a power steering hose that is not to specification. Under
extreme steering maneuvers, such as turning the steering wheel fully to the left or right while braking, the hose may fracture and leak fluid. If this were to
occur, power steering assist would be lost and increased steering effort would be required. On vehicles equipped with hydro-boost power brakes, it could
also result in loss of power brake assist and increased braking effort would be required. If the power steering fluid spray were to spray onto hot engine
parts, an engine compartment fire could occur.
Note:
Some of the affected hoses were shipped to dealers by GMSPO between July 25, 2005 and August 24, 2005 and could have been used to service
1991-2006 vehicles.
Correction
Dealers are to inspect the power steering hose(s) for two suspect date codes and replace them if required.
Dealers who have ordered the involved hoses for service (see listing in Administrative Message) are to search their part sales records to determine the
name and address of the purchaser(s). If the purchaser is the owner of the vehicle, dealers are to send the owner a copy of the appropriate letter shown in
this bulletin requesting them to bring their vehicle in for repair. If the purchaser is a body shop, independent repair shop, etc., dealers are to send the
shop a copy of the appropriate letter shown in this bulletin requesting that they provide the customer's name, address, and telephone number so the dealer
can send the owner a copy of the letter.
