What's wrong?
The exhaust system on 2017-2018 Forest River Dynamax recreational vehicles carries engine exhaust from the engine to the outside of the vehicle. Its tailpipe is supposed to end past the exterior wall, so exhaust gases leave the vehicle body instead of collecting under or near the cabin.
On affected Dynamax vehicles, the exhaust pipe was cut about 3 inches shorter than prior production. Because the pipe does not reach beyond the vehicle's outer edge, exhaust exits too close to the body. If the vehicle is parked with the engine running, carbon monoxide can enter the passenger cabin through open windows or openings in the floor.
There is no warning sign before failure. The problem is the exhaust outlet location, so an owner will not get a light, sound, or driving symptom that proves the cabin is being exposed.

What's the safety risk?
Carbon monoxide entering the passenger cabin increases the risk of injury or death. No warning sign is listed, so do not rely on a light, sound, or smell before scheduling the repair. Use the vehicle cautiously until it is fixed. Repair is free at any franchised Forest River dealer.
What should I do?
- Check your VIN to confirm your 2017-2018 Forest River Dynamax is included in this recall.
- Contact a franchised Forest River dealer to schedule the free stainless steel exhaust-tip installation that lengthens the exhaust outlet tied to the cabin carbon monoxide risk.
- Bring the recall notice if Forest River mailed one. If not, reference recall number 17V724 and Forest River recall 55-0565 when you call.
- Avoid idling while parked with windows open until the repair is complete.
What happens at the repair
At the dealer, a Forest River technician installs stainless steel exhaust tips to lengthen the exhaust outlet. That moves the exhaust discharge farther from windows and floor openings where fumes can enter when the vehicle is parked with the engine running. The recall repair is available now, and the parts and labor are free under campaign 17V724. Ask the service desk to confirm the exhaust tip installation is completed before the vehicle is returned.
