The problem
Certain passenger 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.
The risk
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.
The fix
Dealers will inspect the power steering hose(s) for two suspect date codes and replace them if required. The recall will begin on October 14, 2005. Owners May contact Chevrolet at 1-800-630-2438, GMC at 1-866-996-9463, Buick at 1-866-608-8080, Cadillac at 1-866-982-2339, Isuzu at 1-800-255-6727, or Hummer at 1-800-732-5493.
