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.
14-208
THIS ADVISORY 14-208 INVOLVES 2014 MONTANA HIGH COUNTRY 338DB UNITS MANUFACTURED WITH IMPROPER FURNACE VENTILATION. THE STEPS LEADING TO THE UPPER DECK MUST BE REPLACED TO ALLOW THE ADDITION OF A FURNACE GRILL TO EACH STEP. THIS SERVICE ADVISORY EXPLAINS HOW TO CORRECT THE VENTILATION.
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.
