Defective brake servo vacuum pump: reduced braking assistance (1.2 PureTech turbo)
Manufacturer recallOn the 1.2 PureTech turbo, the vacuum pump that supplies the brake servo can deteriorate, reducing or removing braking assistance. A first recall (Citroën code HFC) covers engines built from March 2013 to April 2017: the pump can be damaged by abrasion from the timing belt, whose debris contaminates the oil. A second recall (codes HLX and HUZ) covers C4 Cactus cars built between 7 February 2017 and 13 November 2019, for insufficient lubrication of the pump.
Fixed free of charge by a dealer and not counted in the reliability score: ask for proof the work was done (invoice, or a VIN check at a dealer).
