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.

Blue Bird Troubleshooting Guides: Blue Bird announcement of the addition of troubleshooting guides for assisting in the service of the Blue Bird products. These troubleshooting guides are available on the Vantage website.
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.
