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#9772
On the 2021 Wonder motorhome the Xantrex inverter electronic breaker is set to 20A and will not charge the coach batteries as efficiently as intended at 30A setting. According to the 2021MY electrical drawings the breaker should have been set at 30A not changed to 20A as in previous 2020MY electrical drawings.
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.
