Defect: 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.
Consequence: Brakes that overheat can increase the risk of a fire.
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 on this record
Complaints from the API and bulk file are merged and deduplicated by ODI number; the API alone misses records.
System and subsystem counts are numbers of distinct complaints, recalls or communications that name them. One record can name several systems, so shares across systems can add to more than 100 percent; a single share never exceeds 100 percent.
Recalls are counted once per campaign, investigations once per action and manufacturer communications once per NHTSA id, even when NHTSA lists several model names for the same record.
A sales denominator is a calendar-year proxy, not the population of vehicles still in use. Rates are copied from verified pipeline output.
NHTSA's complaints API and bulk file list no complaint for this make, model and model year in this data build.
