Summary
Autocar, LLC is recalling certain model year 2011-2013 ACX vehicles manufactured January 24, 2011, through December 4, 2012. These vehicles are equipped with Meritor axle assemblies that were built with disc brakes using MGM J24 series air brake chambers. In the affected axles, the brake chambers may leak pressure allowing the parking brake to drag when it is supposed to be released. Brake dragging could lead to overheated brake components.
Consequence
Overheated brake components could result in a fire.
Remedy
Autocar will notify owners and will replace the actuators as needed, free of charge. The safety recall began on June 10, 2013. Owners may contact Autocar at 1-765-489-5499. Autocar's campaign recall number is A-1301.
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.

Vehicles covered

As listed by NHTSA. A recall usually covers only some vehicles of each model and year, often a production date range.

Has your Autocar 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 Autocar dealer can also check your VIN. Recall repairs are free.
