A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

For certain Winnebago vehicles equipped with Winnebago Connect and a Xantrex Freedom XC PRO 2000 Inverter, a new inverter firmware update is available and must be completed to ensure proper charging operation. If the coach is connected to shore power and the firmware has not been updated, the inverter may prevent the coach from charging. Repair involves an update to the Inverter’s U1 and U3 Firmware.
