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.
ITS61122
Instruction to Service for updating the battery program on certain ELFA2 buses for Improved BMS response to overcharging and other functional safety mechanisms, more robust detection of failure modes through DTCs, improving Battery Data Recorder (BDR) capabilities, streamlined flashing processes, and logic improvements for better integration with application.
ITS60410
This technical instruction describes how to replace dust covers and seal and protect the harnesses associated with the Smart Rider suspension leveling system for 60 foot buses with components installed on all three axles.
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.
