Quick answer

It has come to our attention that on certain 2023-2024 Convoy and 2023 Tiffin (GH1) Motorhomes the Xantrex inverter controller will start charging the battery as intended but will stop charging before it is completely full. The inverter will continue to power 110V components until the battery is completely depleted, causing battery to die faster, and in some instances must be woken up from an external power source, such as another battery. Tiffin Motorhomes will configure the Xantrex Inverter controller, so the settings are changed from flooded battery to lithium to allow for higher capacity. We have also changed the configuration of the inverter to increase battery voltage cutoff limit for 110V output. This will not allow the inverter to power 110V components when the battery voltage reaches this limit.

What this bulletin may mean before buying

Treat this as service research, not a verdict on one car. Before you buy, compare this communication with official recall campaigns, model-level owner complaint patterns, and the exact vehicle’s VIN-decoded specifications. A bulletin can help you ask a seller or dealer sharper questions about software updates, known repairs, warranty extensions and service history.
