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.
PA662
Issued Product Advisory available on web site for XT and XTPro aerials reminding users of inspection requirements. Gave methods to reduce wear from road travel. Provided incentive to preform required inspections for leveling rods inside the insulating boom.
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.
