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.
ITS60418
This technical instruction describes how to replace dust covers and seal and protect the harnesses associated with the Smart Rider suspension leveling system for buses with components only installed on the front axle.
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.
