Defect description

Trans Tech Bus (Trans Tech) is recalling certain 2020 Roadstar, ST Aero and SST buses built on 2019 Chevrolet Express cutaway chassis. The specific models are AC139SSSA409,AC139SSSP500, CC139DMSA409, CC139DMSA500, CC139DMSP500, CC159DMSA509, CC159DMSA600,EC139DBSP400, SC139DSFP500, SC139DSSA409, SC139DSSA500, SC139DSSP500, SC159DSFP600, SC159DSSA509, SC159DSSA600, SC159DSSA603, SC159DSSP600, and SC177DSSA603. The seatbelt-unfastened warning light will not illuminate for approximately five seconds after the ignition is moved to the "on" or "start" position. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 208, "Occupant Crash Protection."

Safety consequence

Without the seatbelt warning reminder, the driver may forget to fasten the seatbelt, increasing the risk of injury in the event of a crash.

Manufacturer remedy

Trans Tech will notify owners, and GM dealers will reprogram the instrument panel cluster, free of charge. The recall began May 6, 2020. Owners may contact Trans Tech customer service at 1-845-988-2333.
