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 fail to comply with the requirements of Federal Motor Vehicle Safety Standard No. 124, "Accelerator Control Systems." if one of the two accelerator pedal return springs fails and the temperature is -22°F to -40°F, the engine may not return to idle within three seconds, as required.

If this were to occur, greater brake pedal force and a longer distance may be required to stop the vehicle.

Dealers will replace the accelerator pedal assembly. This recall is expected to begin during March 2005. Owners should contact Cadillac at 1-866-982-2339.
