Plain-English summary
Spartan Motors, Inc. is recalling certain model year 2015-2016 K2, K3, and MM chassis manufactured between October 2, 2013, and April 2, 2015. The recall involves 144 vehicles where the fasteners attaching the stay rod (v-rod) to the rear drive axle may not have been installed with thread locker or tightened in the correct sequence.
If these fasteners come loose, the stay rod may disconnect from the rear axle. This failure could result in a loss of vehicle control, increasing the risk of a crash.
Spartan will notify owners, and dealers will replace the fasteners using thread lock, tightening them in the proper sequence and with required torque values at no charge. The recall began on August 11, 2015. Owners may contact Spartan customer service at 1-800-582-3454 or the NHTSA Vehicle Safety Hotline at 1-888-327-4236.
