What's wrong?
The onboard gasoline generator on the 2017 Thor Motor Coach Challenger 37YT uses a metal exhaust pipe to carry generator exhaust away from the living area and out from under the motorhome. When the generator is running, that pipe is part of the safety path that keeps exhaust gases, including carbon monoxide, from collecting inside the coach.
On affected motorhomes, the generator exhaust pipe was installed in the wrong location or left off completely during manufacturing. If the pipe is missing or routed underneath the motorhome, generator exhaust can collect where it does not belong and enter the living space. Carbon monoxide has no smell, so the problem is dangerous before an owner can identify it by scent.
The warning sign is the carbon monoxide detector inside the motorhome sounding an alarm while the generator is running. If that alarm sounds, leave the motorhome and get into fresh air before the generator is used again.

What's the safety risk?
An incorrectly installed generator exhaust pipe can let carbon monoxide build inside the motorhome, increasing the risk of personal injury or death. The carbon monoxide detector is the warning device; if it alarms, evacuate the motorhome and contact the dealer before generator use resumes. Repair is free at any franchised Thor Motor Coach dealer.
