Vehicle report
Technical service bulletins are instructions a manufacturer sent its dealers about a known fault. They are not recalls and the work is usually not free, but they are the clearest signal of a problem the manufacturer already knows about.
CA#9848
On certain 2020 & 2021 Wonder models the Firefly Multiplex panel requires a software update to version 3.1.2. The Multiplex panel will try to prime the generator if the furnace is "ON" when the battery disconnect is turned "OFF". SOP2839 is included for instruction on how to perform the Campaign.
CA#9703
The Firefly auto generator start feature periodically turns off shortly after the heating ventilation air conditioner is triggered stalling the generator. A software update to the G12 module to the version 3.10 provided by Firefly has to be performed. A USB stick with the software update and a SOP (Standard Operating Procedure) will be sent out to dealers and retail owners of motorhomes that are affected.
Complaint counts are reports filed with NHTSA, not failure rates. A common model collects more of them than a rare one that breaks more often.
