Recall 17V777 affects 280 2017-2018 Temsa TS30, TS45, and TS35E buses for contaminated fire-suppression dry chemical. Repair is free at any franchised Temsa dealer.
Temsa is recalling 280 2017-2018 TS30, TS35E, and TS45 buses under recall 17V777 because contaminated ABC dry chemical in the engine fire suppression system can discharge improperly. If the system does not suppress an engine fire as intended, injury risk increases; the dealer repair will be free once Temsa makes it available.

What's wrong?
The engine fire suppression system on 2017-2018 Temsa TS30, TS45, and TS35E buses is built to detect and suppress a fire in the engine area. It uses ABC dry chemical, an extinguishing powder, to smother flames before they spread through the engine compartment. The system matters because the engine area carries heat, fuel, oil, and electrical components in a tight space.
On affected buses, the Firetrace system was built with ABC dry chemical from supplier batches that showed inconsistent material quality. That contamination means the powder in the system cannot be trusted to perform as designed. If an engine compartment fire starts, the suppression system can fail to knock down the fire as expected, leaving the bus dependent on other emergency response steps.
There is no warning sign before failure. The bus operator will not have a dashboard light, smell, sound, or driving symptom that proves the dry chemical inside the suppression system is contaminated.

The year and model narrow the scope, but the VIN decides. Check your VIN to confirm whether your specific bus is included.
What's the safety risk?
Contaminants in the fire suppression dry chemical can keep it from discharging correctly during a fire. That can reduce fire suppression and increase the risk of injury. There is no listed warning sign before the system fails to discharge correctly, so schedule the recall work soon. Repair will be free at any franchised Temsa dealer once available.
What should I do?
- Check your VIN to confirm your 2017-2018 Temsa TS30, TS45, or TS35E bus is included in this recall.
- Wait for Temsa's owner notice if your VIN is included and the dealer says the repair is not open for your bus.
- Contact a franchised Temsa dealer with recall number 17V777 and ask when the free fire-suppression dry-chemical replacement is available.
- Call Temsa's agent, CH Bus Sales, at 1-407-271-8935 with questions about recall number 17V777.
- Keep fire-suppression service records with the bus until the contaminated dry chemical is replaced.
What happens at the repair
At the dealer, a Temsa technician replaces the contaminated ABC dry chemical in the engine fire suppression system. Because the remedy status is still under development, treat the final dealer replacement as unavailable until Temsa opens the repair path. Once available, parts and labor are covered under the recall. Temsa began owner notification on January 25, 2018. Temsa's general reimbursement plan is on file for documented eligible expenses, so keep repair paperwork and ask CH Bus Sales how to submit a claim if you already paid for this fire suppression system repair.

Frequently asked questions
What is recall 17V777?
Recall 17V777 covers 280 2017-2018 Temsa TS30, TS45, and TS35E buses with engine fire suppression systems that contain contaminated ABC dry chemical. Contaminated dry chemical can discharge improperly during a fire, reducing suppression performance and increasing injury risk.
What should I do if my 2017-2018 Temsa TS30, TS45, or TS35E is on this recall?
Check your VIN to confirm your specific bus is included in recall 17V777. If it is, contact a franchised Temsa dealer or Temsa's agent, CH Bus Sales, at 1-407-271-8935 to arrange replacement of the dry chemical in the fire suppression system.
Is the recall repair free?
Yes. Federal recall law requires manufacturers to repair safety defects at no cost, and Temsa will replace the dry chemical in the fire suppression system free of charge through its dealer network.
What is the safety risk?
The risk is reduced fire suppression performance. If the ABC dry chemical contains contaminants, it can discharge improperly during a fire, affecting the system's ability to suppress the fire and increasing injury risk for occupants or people near the bus.
What if I bought my Temsa bus used?
The free recall repair still applies. Recall coverage follows the bus, not the first owner. Check your VIN to confirm whether your 2017-2018 Temsa TS30, TS45, or TS35E is included, then reference recall 17V777 when you contact a Temsa dealer or CH Bus Sales.
