Summary: Mertz is recalling certain model year 2010 and 2011 halliburton trailers manufactured from November 2010, through March 2011, and equipped with gunite automatic slack adjusters. Due to an incomplete "knitting" of the iron at the time of casting, inadequate structural integrity of the slack adjuster housing can occur, which could cause the housing to break at the handle under normal operating loads.
Consequence: If the slack adjuster housing were to break, the wheel brake to which the slack adjuster is attached would no longer function, causing the vehicle to have reduced braking capacity and, if mounted on the steer axle, the vehicle could pull to one side, possibly resulting in a crash.
Remedy: Mertz will notify owners and the slack adjusters will be replaced free of charge. The safety recall began on November 8, 2011. Owners may contact mertz at 580-767-8465 or accuride at 1-812-962-5000.
Notes: Owners 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 Mertz 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 Mertz dealer can also check your VIN. Recall repairs are free.
