What's wrong?
The 3 Burner Cooking Stove in the 2021 Coach House Platinum uses LP gas to feed the cooktop burners. A saddle valve connects the burner gas supply to the manifold under the burner surface. That joint needs a tight seal so gas reaches the burners only when a control knob is opened.
On affected stoves, the bolt that secures the saddle valve to the manifold was overtightened during field adjustment. Too much force damages the o-ring seal at that joint. Once the seal is damaged, LP gas leaks inside the stove enclosure instead of staying contained in the gas line.
The warning sign is a strong rotten egg smell from the odorant added to LP gas. If that smell is present, gas is in the air and the area is not safe until the leak is fixed and the gas has dissipated.
Who's affected?
The scope centers on the LP gas 3 burner cooking stove, listed under appliance and LPG system components.

A matching year and model does not guarantee inclusion. Check your VIN to confirm whether your specific motorhome is included.
What's the safety risk?
A gas leak raises the risk of fire. A rotten egg smell is the warning sign for leaking LP gas. If you smell it, leave the area immediately and keep ignition sources away until the leak is fixed and the gas clears. Repair will be free at any franchised Coach House dealer once available.
