- Summary
- 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.
- Consequence
- 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 which could result in a crash.
- Remedy
- Dealers will (1) inspect the left engine exhaust manifold clip for proper alignment and placement on the body-mounted stud. If incorrect, they will reposition the clip on the brake lines and reinstall the clip on the stud; (2) the dealer will verify that both rear brake lines have the proper clearance to the left exhaust pipe. They will reposition the lines by bending as necessary; (3) dealers will remove the machining tab from the rear differential housing. Also, dealers are to inspect the brake lines for wear in these related areas and repair or replace if there is any sign of wear-through on the nylon overcoating. The recall began on January 18, 2005. Owners should contact Cadillac at 1-866-982-2239 or Chevrolet at 1-800-630-2438.

Has your Cadillac been repaired?
Recalls here come from NHTSA’s records for the model and year. Not every vehicle of a model is included in every recall, and this site can’t see whether a repair has been done. Only a VIN lookup can tell you that.
NHTSA’s VIN search doesn’t show recalls that were already repaired, recalls more than 15 years old, or some small manufacturers’ recalls. A Cadillac dealer can also check your VIN. Recall repairs are free.
