What this recall covers

NHTSA's campaign record, quoted as published

The defect

ON THE INVOLVED VEHICLES, THE BRAKE MASTER CYLINDER MAY HAVE BEEN ASSEMBLED WITH RESERVOIR MOUNTING BOLTS THAT WERE IMPROPERLY PROCESSED. THIS COULD MAKE THESE BOLTS BRITTLE AND SUBJECT TO BREAKING. IF BREAKAGE OCCURS, A BRAKE FLUID LEAK MAY DEVELOP BETWEEN THE RESERVOIR AND MASTER CYLINDER. LOSS OF BRAKE FLUID WOULD ADVERSELY AFFECT VEHICLE BRAKING CAPABILITY.

The remedy

DEALER WILL REPLACE THE MASTER CYLINDER RESERVOIR MOUNTING BOLTS WITH AN IMPROVED TYPE, WITHOUT CHARGE TO OWNER.

A safety recall is issued when a manufacturer or NHTSA determines that a vehicle has a safety-related defect or does not comply with a federal motor vehicle safety standard. Recall repairs are free. Whether a specific vehicle is covered depends on its VIN — a recall listed for a model year does not necessarily apply to every vehicle of that year.
