An official CAA Japan notice concerns Passenger car (Mercedes-Benz S300h) - Repair. Due to a defect in the engine (vacuum pump). ■ Defective component (part name): Engine (vacuum pump). ■ Structure, equipment or performance considered noncompliant with the standards, and its cause: The internal components of the vacuum pump in hybrid vehicles have insufficient durability and may break during use, preventing the pump from generating vacuum. If the vehicle continues to be used in this condition, insufficient vacuum may prevent proper engine control, causing the engine warning light to illuminate and the vehicle to enter fail-safe mode. In the worst case, exhaust emissions may exceed the standard limits. The decrease in vacuum may also cause the brake warning light to illuminate. Published 2017-11-16.
What to do now
(Recall) 外-2560 ■ Corrective measures: Replace the vacuum pump with an improved part on all vehicles.
