Summary
Wabash is recalling certain model year 2010 and 2011 vans manufactured from October 15, 2010 through January 31, 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
Slack adjusters with this flow notch could crack under normal braking conditions causing loss of braking which could result in a vehicle crash.
Remedy
Wabash will notify owners and dealers will replace the subject slack adjusters free of charge. The safety recall began on may 12, 2011. Owners may contact gunite customer service at 1-800-677-3786 or wabash at 765-771-5605.
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.

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 Wabash National 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 Wabash National dealer can also check your VIN. Recall repairs are free.
