What's wrong?
The PowerGlide chassis controller on affected 2022-2025 Tiffin Zephyr, Phaeton, and Allegro Bus motorhomes is an electrical control module for chassis functions. It helps route power and signals for systems tied to the ignition circuit, so the engine and chassis electronics stay powered in the correct sequence.
On these motorhomes, the IFM controller circuit does not have enough protection against an overcurrent, which means more electrical load than the circuit is designed to handle. Systems on the same power distribution circuit as the chassis ignition can overload that circuit. When that happens, a fuse can blow and the engine can shut down.
There is no warning sign before failure. The owner is not expected to see a light, hear a sound, or feel a change before the fuse blows and the engine shuts down.

What's the safety risk?
An engine shutdown while driving increases the risk of a crash because the motorhome loses propulsion in traffic. There is no warning sign before failure, so drive cautiously and schedule the circuit protection repair soon if your VIN is included. Repair is free at any franchised Tiffin dealer.
