Defect
THE REAR BRAKE MASTER CYLINDER PLASTIC PISTON EMPLOYS A NON-SPECIFIED MATERIAL WHICH MAY ALLOW EXCESSIVE WATER ABSORPTION. AS A RESULT, THE PLASTIC PISTON MIGHT STICK IN THE MASTER CYLINDER PISTON BORE AND CAUSE BRAKE DRAG.
Remedy
DEALER WILL REPLACE REAR BRAKE MASTER CYLINDER PISTONS WITHOUT CHARGE TO OWNER.
The record is thin — 0 NHTSA complaints — so owner-report data can't strongly confirm reliability either way, though 1 recall should be verified as completed.
