Type and modelnumber
VINs of the affected vehicles are in the range from YYCFT26B37J004001 to YYCFT26B4AU005454.

Danger
Injuries

The product poses a risk of injuries because the water tightness of the brake vacuum pump may become reduced, allowing water to seep in when the cars are washed and potentially resulting in a loss of braking power and a risk of accident.

Measures
Voluntary corrective actions taken by the manufacturer.

Spain

RAPEX Reference no.
