What's wrong?
The affected 2011-2015 Freightliner M2 and Cascadia trucks use a compressed natural gas cabinet tank to store fuel under pressure. The tail pipe is supposed to carry hot exhaust gases away from heat-sensitive parts, including the fuel system, before those gases leave the truck.
On these trucks, the tail pipe ends under the CNG tank area. That placement directs exhaust heat toward the fuel system instead of away from it. The problem is the exhaust layout, not the tank itself, and the concern is heat exposure around compressed natural gas storage.
There is no warning sign before failure. An owner or driver should not expect a dashboard light, smell, sound, or change in engine behavior to identify this condition before the fuel system is exposed to excess heat.

A matching year and model does not confirm inclusion. Check your VIN to confirm whether your specific truck is included.
What's the safety risk?
Exhaust heat around the fuel system can overheat fuel components and increase the risk of a vehicle fire. Schedule the recall repair soon and pay attention to unusual heat, smoke, or fuel odor while the vehicle is in use. Repair will be free at any franchised Freightliner dealer once available.
What should I do?
- Check your VIN to confirm your 2011-2015 Freightliner M2 or Cascadia is included in this recall.
- Use the Freightliner owner notice if you have it, or contact Freightliner customer service at 1-800-745-8000 before scheduling service.
- Ask a franchised Freightliner dealer about the free tailpipe extension that moves exhaust heat away from the CNG fuel system.
- Reference recall number 14V680 and Freightliner recall FL-671 when you call.
- Avoid long idling or heavy heat buildup near the CNG fuel system until the tailpipe extension is complete.
What happens at the repair
At the dealer, a Freightliner technician extends the exhaust tailpipe so it exits beyond the cabinet instead of ending under the compressed natural gas tank area. That moves hot exhaust farther from the fuel system components named in recall 14V680. The filing does not show an open final remedy status here. The dealer repair will be free once available. Parts and labor are covered under the recall.
