Recall 15V479 covers 64 2013-2016 Temsa TS45 coaches for low rear axle parking brake air pressure. Repair is free at any franchised Temsa dealer.
Temsa is recalling 64 2013-2016 TS45 coaches because low output pressure from the inversion relay valve can leave too little air pressure for the rear axle parking brake system. The parking brakes can drag while the coach is moving, overheat the disc brakes, and increase fire risk; the Temsa dealer repair will be free once available.

What's wrong?
The inversion relay valve on a 2013-2016 Temsa TS45 is part of the air-operated parking brake system for the rear axle. In normal use, it sends the right air pressure to the rear parking brakes so they release and apply as intended. The rear brakes depend on steady air pressure, not just mechanical linkage, to stay fully released while the coach is being driven.
On affected coaches, the valve's output pressure does not stay stable after installation. The pressure drops over time, leaving the rear axle parking brake system with too little air pressure. When that happens, the rear parking brake can partially engage when it should be released, which adds drag and heat at the rear axle.
Owners or drivers can notice smell or smoke from the rear axle area. Treat that as the warning sign, because it points to a rear parking brake that is not fully released.
Who's affected?
The scope is limited to the TS45 bus, with the same air parking brake component listed for every model year in this recall.
| 2014 Temsa TS45 | Air |
|---|---|
| 2015 Temsa TS45 | Air |
| 2013 Temsa TS45 | Air |
| 2016 Temsa TS45 | Air |
| Units affected | 64 |
| Field incidents | NHTSA has logged no field incidents to date. |
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?
Low air pressure can make parking brakes drag while the vehicle is moving. Dragging brakes can overheat the rear disc brakes and increase the risk of fire. Treat smoke or a burning smell near the rear axle as a reason to stop and call the dealer. Repair will be free at any franchised Temsa dealer once available.
What should I do?
- Check your VIN to confirm your 2013-2016 Temsa TS45 is included in this recall.
- Contact Temsa customer service at 1-404-602-0151 to ask when the free parking-brake repair is open.
- Reference recall number 15V479 when you call Temsa or speak with a franchised Temsa dealer.
- Keep the coach out of service if the rear parking brakes drag while driving or the disc brakes overheat.
- Arrange the free repair once Temsa opens it; the dealer repair addresses the low inversion-relay-valve pressure that leaves the rear parking brake system with insufficient air pressure.
What happens at the repair
The filing says Temsa will notify owners and dealers will repair the vehicles free of charge. Because the remedy is still listed as under development, treat the final dealer repair as not open for scheduling until Temsa or the dealer confirms it. Once available, a Temsa technician will correct the rear axle parking brake air pressure problem tied to the inversion relay valve, so the parking brake system receives the pressure it needs. Parts and labor will be free once the repair opens.
