What's wrong?
The exhaust pipe outlet on the 2022 Freightliner Cascadia is the end of the exhaust system. It directs hot exhaust gases away from the engine, battery box, wiring, and nearby frame components after the engine has burned fuel. On trucks with the Cummins engine and battery boxes mounted between the frame rail, its direction matters because the outlet carries heat and residue into a tight area.
On affected Cascadias, the exhaust pipe outlet was installed with the tip facing the battery box mounted directly above the frame rail. That points hot exhaust at surrounding parts instead of sending it away from them. Over time, heat and exhaust residue can damage nearby components, including melting materials around the battery box and frame area.
Before a failure becomes obvious, owners can see exhaust residue on nearby components. They can also notice melted surrounding parts or a smell like melted material near the battery box area. These signs mean the exhaust outlet is directing heat where it does not belong.

What's the safety risk?
Exhaust heat can melt the battery box and increase the risk of a fire. Watch for exhaust residue on nearby parts, melted surrounding components, or a melted-material smell. If you notice those signs, park safely and call the dealer. Repair is free at any franchised Freightliner dealer.
