## What is wrong

Temsa is recalling certain 2021\-2025 TS30, TS35, and 2021\-2026 TS45 buses equipped with a Mux5\-B multiplex.  The temporary bus stop valve may activate unintentionally and apply the brakes, causing them to overheat.


## What can happen

Brakes that overheat can increase the risk of a fire.


## The remedy

Temsa will inspect the multiplex, update the software, and repair the wiring harness as necessary, free of charge.  Owner notification letters were mailed June 11, 2025.  Owners may contact Temsa customer service at 1\-833\-628\-3672.


## Notes

Owners may also contact the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1\-888\-327\-4236 \(TTY 1\-888\-275\-9171\) or go to nhtsa.gov.
