On certain heavy duty class 8 trucks equipped with holland air suspension systems, a transverse beam casting may fracture under normal loads.

Summary: On certain heavy duty class 8 trucks equipped with holland air suspension systems, a transverse beam casting may fracture under normal loads. If a casting breaks when the vehicle is traveling on a roadway there is the potential for pieces of the casting to become projectiles and the suspension's transverse beam may drop down low enough to contact the road surface.
Consequence: This will cause sparks that could potentially ignite and cause a fire.
Remedy: Dealers will inspect and replace the defective transverse beam assemblies. The recall began on August 19, 2005. Owners may contact mack trucks at 610-709-2131.
Notes: Mack trucks recall NO.SC0300 and SC301.CUSTOMERS may also contact the national highway traffic safety administration's vehicle safety hotline at 1-888-327-4236 (TTY: 1-800-424-9153); or go to http://www.safercar.gov.

Has your Mack 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.

Check your VIN with NHTSA

NHTSA’s VIN search doesn’t show recalls that were already repaired, recalls more than 15 years old, or some small manufacturers’ recalls. A Mack dealer can also check your VIN. Recall repairs are free.
