Complaints by component

NHTSA holds no complaints for this model year in this dataset.

Chassis

A family can be built on more than one chassis. Only chassis that a recall notice names for these model years are listed, so a chassis missing here is a gap in the record. A chassis recall covers only the vehicles its own notice describes, by build date and VIN range; check the notice before assuming it applies to a particular coach.

Canadian notices

Transport Canada publishes its own notices with their own IDs. They are separate records from the U.S. campaigns above and are never merged with them.
