An official CAA Japan notice concerns Passenger cars (Honda N-BOX and 7 other models) - Repair. Engine (exhaust gas recirculation system) defect. ■ Defective component (part name): Engine (exhaust gas recirculation system). ■ Condition of the structure, equipment or performance deemed noncompliant with standards and its cause: In the exhaust gas recirculation (EGR) system fitted to naturally aspirated engines, the EGR pipe flange material and EGR operating control program are inappropriate. Repeated short-distance driving while the engine is cold may therefore cause condensation to accumulate on the pipe flange and around the EGR valve opening, causing corrosion. Continued use in this condition may cause corroded fragments to become trapped between the EGR valve and valve seat. In the worst case, the engine may stop while driving and become unable to restart. Published 2025-01-31.
What to do now
(Recall notification number) 5613. ■ Corrective measures: ① On all vehicles, replace the EGR pipe with an improved part, reprogram the engine control computer with the corrective program, and remove rust around the EGR valve opening. Because supplying the improved parts will take time, customers who wish to do so can have the corrective program installed first. They will be contacted again when parts are available, and the pipe will then be replaced with the improved part. ② On all vehicles, replace the EGR pipe with an improved part and remove rust around the EGR valve opening. Because supplying the improved parts will take time, customers will be contacted again when parts are available, and the pipe will then be replaced with the improved part.
