What's recalled

Component: Other (school bus stop arm assembly)

Daimler Trucks North America LLC (DTNA) is recalling certain 2017-2020 Thomas Built Buses Saf-T-Liner C2 school buses configured with a specific Switch Hub Module (part numbers 204803 and 216434) combined with a 500k Bulk Head Module and a certain 3-position momentary switch warning light package. The Switch Hub Module (SHM) that controls the exterior warning lights and stop sign may fail, resulting in deactivation of the red warning lights, stop sign and system indicator.

The risk

If the exterior warning lights and stop sign indicator stop working, other drivers may inadvertently proceed driving before the school bus loading/unloading of students is complete, increasing the risk of an injury.

The remedy and its status

DTNA will notify owners, and dealers will update the SHM, free of charge. The recall began April 15, 2020. Owners may contact DTNA customer service at 1-800-547-0712. DTNA's number for this recall is FL-844.

Status: NHTSA lists Apr 15, 2020 as the owner-notification date for this campaign.

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.
