On April 20, 2026 we discovered our 2025 Tiffin Wayfarer was experiencing a thermal runaway of the house battery charging system. The coach was in storage at a public RV storage facility. Our unit is a single enclosed unit with a roll up door. When we opened the bay door, we could tell the entire storage bay and coach were severely filled with toxic H2S gas. After the bay had been allowed to ventilate, I disconnected the shore power to stop the charging process. I called Tiffin Motorhomes Tech Support the next day and spoke with the Wayfarer specialist, Keith Hawkins. He said this was a known issue and they were working on trying to determine the cause.. Keith called me the on April 26, 2026, and told me that he had determined the cause was Tiffin had been incorrectly wiring the house batteries, specifically they had been been attaching the ground wire to the wrong battery.
