My 2022 Mercedes-Benz Metris recently experienced a sudden onset of engine issues, triggering the Check Engine Light. Diagnostic data retrieved from the vehicle (via onboard telematics) revealed the following error codes via onboard OBD GPS Bouncie: P0300: Random/Multiple Cylinder Misfire Detected P0301: Cylinder 1 Misfire Detected P0304: Cylinder 4 Misfire Detected Upon professional inspection, a mechanic diagnosed the root cause of these misfires as critically low fuel pressure resulting from a failed low-pressure fuel pump. The mechanic advised that the fuel pump requires immediate replacement. These symptoms (low fuel pressure causing engine misfire and potential stall) align exactly with the safety defect described in NHTSA Recall Campaign #23V881 (and the related #23V444). That recall describes a defect where the fuel pump impeller deforms and meets resistance, causing a drop in fuel delivery and potential loss of motive power. Despite my vehicle being the same model year (2022) and suffering the identical component failure described in the recall documents, my VIN [XXX] ) is currently excluded from the eligibility list. Corrective Action Sought: I request that the NHTSA investigate this failure as evidence that the scope of Recall #23V881 is insufficient. The defective fuel pump components appear to be present in my vehicle's production batch. I request the manufacturer be compelled to expand the recall to cover my VIN for repair and reimbursement. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
