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.
1Z9-V8T4B-10
This Technical Service Bulletin provides an inspection guide and corrective actions for travel trailers sold with an optional Xantrex inverter that potentially have a missing inverter chassis ground wire or were installed using improper hardware on the inverter chassis ground.
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.
