What's wrong?
The R1731 cooking stove in the 2018 Rossmonster Ram Promaster uses a saddle valve at the gas manifold. The manifold routes LP gas to the stove, and the saddle valve connection depends on a small O-ring seal to keep gas inside the system while the appliance is in use or connected.
On affected vans, the bolt that secures the saddle valve to the manifold was overtightened during field adjustment. That extra force damages the O-ring, the rubber ring that seals the connection. Once the seal is damaged, gas escapes at the stove connection and the leak continues until the gas supply is shut off or the parts are replaced.
There is no warning sign before failure. If you smell gas near the stove or inside the RV, stop using the appliance, shut off the gas supply if you can do so safely, and have the recall repair handled before using the system again.
Who's affected?
Both listed components point to the same R1731 cooking stove and its LPG system.
