Defect description
Spartan Motors, Inc. (Spartan) is recalling certain model year 2015-2016 K2, K3 and MM chassis manufactured October 2, 2013, to April 2, 2015.

The recall began on August 11, 2015. Owners may contact Spartan customer service at 1-800-582-3454. Spartan's number for this recall is 15010.
