Defect description
Daimler Coaches North America (DCNA) is recalling certain 2018-2019 Setra S407 and 2019-2020 Setra S417TC motorcoaches. These vehicles are equipped with a driver-selected Electronic Stability Control (ESC) "OFF" switch for disabling the traction control portion of ESC, allowing it to remain disabled at speeds above 20 km/h. As such, these vehicles fail to comply with Federal Motor Vehicle Safety Standard (FMVSS) number 136, "Electronic Stability Control."
Safety risk
If the vehicle is operated above 20 km/h while the Electronic Stability Control system is disabled, there is a greater chance of loss of stability control, increasing the risk of a crash.
Manufacturer remedy
DCNA will notify owners, and dealers will replace the "ESC OFF" switch with a new "TC-Off" button, install an indicator light on the dashboard to indicate when the traction control is deactivated, and perform a software to prevent the ESC system from being disabled, update free of charge. This recall began September 7, 2020. Owners may contact DCNA customer service at 1-800-206-9728. DCNA's number for this recall is 43.54U20107A.
