INFINITI M45 intermittent engine shutdown while driving, restarts in neutral on INFINITI M45

Some Infiniti M45 owners report experiencing intermittent engine shutdowns while driving, which may restart only in neutral. These shutdowns could be linked to various issues, including potential fuel system problems indicated by dropping fuel pressure just before stalling. Additionally, some owners have encountered communication errors between the Engine Control Module (ECM) and the Immobilizer Control Module (IMMU), triggering OBDII codes such as B2193. In more severe cases, a sudden shutdown accompanied by unusual noises may suggest low oil levels, risking engine failure. Electrical problems within the vehicle's systems have also been noted as a cause of these intermittent shutdowns. To mitigate these risks, regular maintenance checks, including monitoring oil levels, are recommended. Owners experiencing these issues are advised to consult a certified mechanic or dealership for prompt diagnosis and resolution to avoid further complications.
