Product Safety - Hydro-Boost Accumulator Over-Pressurization #05006 - (Mar 23, 2005)
05006 -- Hydro-Boost® Accumulator Over-Pressurization
2004 Chevrolet Kodiak

2004-2005 Chevrolet Avalanche, Express, Silverado, Suburban

2004 GMC TopKick

2004-2005 GMC Savana, Sierra, Yukon XL

2004-2005 HUMMER H2

Condition
General Motors has decided that a defect, which relates to motor vehicle safety, exists in certain 2004 Chevrolet Kodiak and GMC TopKick; 2004-2005 Chevrolet Avalanche, Express, Silverado, Suburban; GMC Savana, Sierra, Yukon XL; and HUMMER H2 vehicles. On some of these vehicles, the hydraulic brake booster’s pressure accumulator may crack and/or separate from the Hydro-Boost® assembly during normal vehicle operating conditions. If a separation were to occur and the hood of the vehicle were open, fragments from the accumulator could cause injury to people in the immediate area. In addition, the presence of this crack or fractured surface could allow the hydraulic fluid to leak from the accumulator circuit of the booster assembly. The loss of fluid would cause increased steering and braking effort.

Correction
Dealers are to inspect the hydraulic brake booster, and replace it if necessary.

Vehicles Involved
Involved are certain 2004 Chevrolet Kodiak and GMC TopKick; 2004-2005 Chevrolet Avalanche, Express, Silverado, Suburban; GMC Savana, Sierra, Yukon XL; and HUMMER H2 vehicles built within these VIN breakpoints:
