The short answer
NHTSA received Daimler Trucks North America LLC’s report on Feb 26, 2020. Copied from NHTSA on Oct 19, 2026.
Every line below is in NHTSA’s own words, with its source beside it.
What’s wrong with it?
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.
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.
