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.

The updated banjo bolts feature enhanced corrosion resistance and are designed to replace the current banjo bolts to help minimize corrosion-related issues that may affect air dryer performance and reliability.

TSIB 26-06
Bulletin to follow when replacing LV batteries on buses equipped with certain Vanner battery equalizers.
TSIB 25-03
This TSIB identifies the special procedures necessary when the bus is not in regular use and the air compressor is operated at a low duty cycle.
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.
