Certain passenger vehicles were produced with one or both rear brake hydraulic lines that can come in contact with or be affected by heat from the left engine exhaust manifold and the left exhaust pipe. The brake fluid could reach elevated temperatures and boil.

If the brake fluid boils in a rear brake line, the effectiveness of the rear brake system would be reduced which could result in a brake line leak and loss of brake fluid. If enough fluid leaks from the rear brake system so that brake pedal application can no longer build pressure to the rear brakes. The operator of the vehicle will experience limited braking that could result in a crash.

Dealers will inspect and replace left engine exhaust manifold, the left exhaust pipe, the rear differential housing units and inspect brake lines for wear in these related areas and repair or replace wear-through on the nylon overcoating. The manufacturer has not yet provided with an owner notification schedule. Owners should contact Chevrolet at 1-800-630-2438.

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.

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.

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 should contact Chevrolet at 1-800-630-2438.
