NHTSA Complaint #11439442 — 2009 MAZDA MAZDA3

The fuel pump lock ring on my 2009 Mazda Mazdaspeed3 has failed which is causing two engine codes: P0442 and P0455. In addition there is a strong smell of gasoline fumes around the rear of the car after driving and parking. The fuel pump lock ring is a plastic threaded ring which secures and seals the fuel pump and fuel level sender to the fuel tank. Mazda has released a safety recall 5121I for MY2009-2011 RX-8 and MY2006-2007 Mazdaspeed6 vehicles. Mazda states: "On certain subject RX-8 and Mazdaspeed6 vehicles, improper installation of the fuel pump mounting rings may lead to cracking of the rings, causing fuel leakage. In addition, on certain RX-8 vehicles, the fuel pump mounting rings may deteriorate due to heat exposure from the engine and exhaust pipe due to insufficient heat resistance at the top side of the fuel tank. This may also lead to cracking of the rings, causing fuel leakage. Fuel leakage may result in increased risk of fire in the presence of an ignition source near the vehicle." The faulty part number for the RX-8 matches that of the Mazdaspeed3. That is Mazda part number: BN8F-42-167 I believe the failure of this part and recall should extend to affected Mazda 3 vehicles, and any other models with the same part. I have opened a case with Mazda Corporate. Case number: 14466166445 I have uploaded a video of the smoke test performed by a local shop indicating the leak is coming from the ring: https://photos.app.goo.gl/6t6KeeaDPLgGzvvaA I have also attached a screenshot of the video, unfortunately the image quality provided by the mechanic is very poor.
