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.
1ST-TSB202-05292026
In certain model year 2026 Interstate 19’ and Interstate 24’ touring coaches, the grounding bolt connecting the main battery ground and alternator ground to the chassis was not properly fastened.
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.
