What's wrong?
The fuel hoses on the 2024 Temsa TS35 carry diesel from the remote Stage 2 fuel filter to the engine. These hoses use quick connect fittings, which are designed to hold the hose firmly in place while fuel moves under normal operating pressure. The engine depends on that steady supply to keep running as commanded.
On affected TS35 vehicles, the connector crimp on the remote fuel filter hose was not tight enough. That weak crimp can let the hose separate from the fitting. Once the hose moves out of place, diesel fuel can leak, and the engine can lose the fuel supply it needs.
A person operating or standing near the vehicle can see smoke, see other visible signs of a fuel leak, or smell diesel fuel. Those are the warning signs to take seriously before the hose separates further.

What's the safety risk?
A fuel leak near an ignition source increases the risk of a fire. Loss of fuel can stall the engine and increase the risk of a crash. If you see smoke, visible fuel, or smell diesel fuel, stop using the bus and contact a Temsa dealer. Repair is free at any franchised Temsa dealer.
What should I do?
- Check your VIN to confirm your 2024 Temsa TS35 is included in this recall.
- Contact a franchised Temsa dealer to schedule the free fuel-filter-hose replacement that addresses the fuel leak and loss of fuel supply.
- Bring the recall notice if Temsa mailed one. If not, reference recall number 24V549 when you call.
- Avoid operating the vehicle until the repair is complete if you smell fuel, see fuel leaking, or the engine stalls.
What happens at the repair
At the dealer, a Temsa technician replaces the remote fuel filter hoses connected to the Cummins L9 diesel engine. The recall repair is free, with parts and labor covered. Out-of-pocket repairs already paid are handled through the manufacturer's limited warranty, not through a separate reimbursement program, because Cummins says any product failure before the owner notice would have been corrected under that warranty. Ask the service desk how warranty coverage applies if you have prior repair paperwork.
