- Summary
- Mack Trucks, Inc. (Mack) is recalling certain model year 2014 CXU tractor trailers manufactured June 21, 2013, through October 4, 2013 and equipped with an automatic over-speed protection system. In the affected vehicles, the protection system, designed to monitor diesel engine speed and shutdown the engine should it rev excessively, may be wired incorrectly and may not operate as designed.
- Consequence
- Without a system to control the engine speed, if airborne hydrocarbons (combustible vapors) enter through the air intake, excessive engine speed may result in a catastrophic engine failure and/or engine fire.
- Remedy
- Mack will notify owners, and dealers will correct the system wiring, free of charge. The recall began on February 20, 2014. Owners may contact Mack Trucks at 1-336-393-2000. Mack's number for this recall is SC0374.
- Notes
- Owners may also contact the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236 (TTY 1-800-424-9153), or go to 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.
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.
