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.
14-209
THIS ADVISORY 14-209 INVOLVES COLEMAN UNITS MANUFACTURED WITHOUT A ROOF VENT FOR THE REFRIGERATOR. A ROOF VENT MUST BE ADDED FOR PROPER OPERATION OF THE REFRIGERATOR. THIS SERVICE ADVISORY EXPLAINS HOW TO ADD THE VENT.
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.
