Chassis
- Mercedes-Benz Sprinter (medium confidence). Named as the chassis for these model years in NHTSA notices 20V308000, 20V312000, 20V444000.
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.
