Service bulletins for the 2014 Mazda Mazda3

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

MT-002-21a2021-10-31. Service bulletin. FUEL SYSTEM, GASOLINE; FUEL SYSTEM, OTHER. Ethanol is becoming a common additive in gasoline. Gasoline containing ethanol is likely available at your local gasoline station. Typical blends of ethanol include E10 and E85. E10: A blend of 10% ethanol and 90% gasoline. E85: A blend of 85% ethanol and 15% gasoline All Mazda vehicles can run on gasoline containing up to 10% ethanol (E10) but only some 1999-2001 B3000 trucks can run on gasoline with more than 10% ethanol blended. E10 compatible vehicles: All Mazda vehicles. E85 compatible vehicles: 1999-2001 B3000 Mazda trucks with the 8th VIN digit is V.
01-018-162021-01-25. Service bulletin. BACK OVER PREVENTION; FUEL SYSTEM, GASOLINE. Unusual engine noise after a cold engine start. Some customers may complain about an unusual noise coming from the engine compartment for about 20 seconds after a cold engine start. This noise is a normal engine operation for improved exhaust gas emissions. The noise does not indicate a malfunction.
00-003-19-35832019-03-21. Service bulletin. FUEL SYSTEM, DIESEL:STORAGE:TANK ASSEMBLY; FUEL SYSTEM, GASOLINE; ENGINE AND ENGINE COOLING; EQUIPMENT. In support of the new MRT distribution, Mazda will ship to dealers a new Dual Purpose Diagnostic Leak Detector beginning March, 2019. Training videos will be posted to MGSS shortly and Workshop Manual procedures will be revised gradually.
01-005-18-34152018-05-07. Service bulletin. FUEL SYSTEM, GASOLINE; ENGINE AND ENGINE COOLING:EXHAUST SYSTEM. Some vehicles may experience a rough idle with the check engine light on and DTC P0015 / P0524 stored in memory. P0015:00 - Exhaust CMP timing over-retarded P0524:00 - Engine oil pressure too low This is caused by a drop in engine oil pressure due to a piece of foreign object stuck on the oil pump pressure relief valve or oil control valve (OCV). The temporary entry of the foreign object triggers a check engine light on, but rough idle will not be produced until a later time.
RF-16-03R12018-04-23. Service bulletin. FUEL SYSTEM, OTHER:FUEL FILTER. The SKYACTIV®-G 2.5T engine requires a unique oil filter (PY8W-14-302) which is NOT interchangeable with other SKYACTIV® oil filters. The unique oil filter can be identified with two white bands as shown below.
01-003-17-3297a2017-08-10. Service bulletin. FUEL SYSTEM, OTHER:STORAGE:TANK ASSEMBLY:PRESSURE RELIEF DEVICES; EQUIPMENT:ELECTRICAL. When the engine is started for the first time after parking overnight in cold weather (below freezing), some vehicles may exhibit the check engine light on with DTC P0451:00 (Fuel tank pressure sensor: sensor characteristic malfunction) stored in memory.This concern may be caused by an increase in discharge resistance due to water accumulated and frozen in the canister vent hose.
01-002-15-30052017-05-25. Service bulletin. FUEL SYSTEM, GASOLINE:DELIVERY:FUEL PUMP. SOME VEHICLES MAY EXHIBIT A TAPPING NOISE COMING FROM INSIDE THE FUEL TANK (UNDER THE REAR SEAT) WHEN IDLING AFTER THE FUEL TANK HAS BEEN FILLED UP. THE NOISE DISAPPEARS AFTER DRIVING AND CONSUMING SOME FUEL. THE CONCERN WILL LIKELY OCCUR IF THE FUEL TANK IS OVERFILLED (MORE FUEL IS ADDED AFTER THE FUEL PUMP NOZZLE SHUTS OFF AUTOMATICALLY) OR FILLED UP NORMALLY IN HIGH AMBIENT TEMPERATURES AND THE FUEL EXPANDS. THIS NOISE IS CAUSED WHEN THE FLOAT INSIDE THE ROLL OVER VALVE (ROV) MOVES UP AND DOWN WHEN THE TANK IS OVERFILLED. TO CORRECT THE PROBLEM, THE ROV HAS BEEN MODIFIED TO RESTRICT THE UP AND DOWN MOVEMENT OF THE FLOAT.

THE CONCERN WILL LIKELY OCCUR IF THE FUEL TANK IS OVERFILLED (MORE FUEL IS ADDED AFTER THE FUEL PUMP NOZZLE SHUTS OFF AUTOMATICALLY) OR FILLED UP NORMALLY IN HIGH AMBIENT TEMPERATURES AND THE FUEL EXPANDS. • FOR JAPAN BUILT MODELS: THIS NOISE IS CAUSED WHEN THE FLOAT INSIDE THE ROLL OVER VALVE (ROV) MOVES UP AND DOWN WHEN THE TANK IS OVERFILLED. TO CORRECT THE PROBLEM, THE ROV HAS BEEN MODIFIED TO RESTRICT THE UP AND DOWN MOVEMENT OF THE FLOAT. • FOR MEXICO BUILT MODELS: THE NOISE IS CAUSED BY AIR BUBBLES FROM THE SHUT OFF VALVE (SOV) WHEN THE FUEL TANK IS OVERFILLED. TO CORRECT THE PROBLEM, THE SOV HAS BEEN IMPROVED TO PREVENT THIS CONCERN.
09-048-14-29752017-05-11. Service bulletin. FUEL SYSTEM, OTHER:STORAGE:FUEL GAUGE SYSTEM. SOME CUSTOMERS MAY COMPLAIN THAT THE FUEL GAUGE SHOWS EMPTY AND/OR THE DISTANCE-TO-EMPTY ON THE MULTI-INFORMATION DISPLAY (MID) INDICATES “0” WITH A CERTAIN AMOUNT OF FUEL REMAINING IN THE TANK.THIS MAY BE A NORMAL OPERATION OF THE FAIL-SAFE FUNCTION:1.IF FOREIGN MATERIAL (CONTAINED IN A POOR-QUALITY FUEL) ADHERES TO THE FUEL GAUGE SENDER UNIT, THE FAIL-SAFE FUNC-TION INITIATES BY FORCING THE FUEL GAUGE AND THE DISTANCE-TO-EMPTY TO INDICATE “ZERO FUEL AMOUNT”.2.IMMEDIATELY AFTER THE FOREIGN MATERIAL IS DISLODGED BY SHAKING OF THE FUEL DURING DRIVING OR REFUELING, THE FUEL GAUGE WILL RETURN TO A NORMAL READING, BUT THE DISTANCE-TO-EMPTY WILL CONTINUE TO READ “0” UNTIL THE NEXT REFUEL-ING OF 3 US GALLONS (10 LITERS) OR MORE.TO CORRECT THE PROBLEM THE FOLLOWING CHANGE HAS BEEN MADE:1.THERE IS NO MASS-PRODUCTION CHANGE TO PREVENT ADHESION OF FOREIGN MATERIAL TO THE FUEL GAUGE SENDER UNIT. SO THE FACT REMAINS UNCHANGED THAT THE FUEL GAUGE AND THE DISTANCE-TO-EMPTY INDICATE “ZERO FUEL AMOUNT” WHEN FOREIGN MATERIAL ADHERES TO THE FUEL GAUGE SENDER UNIT, AND THE FAIL-SAFE FUNCTION INITIATES.2.TO EQUALIZE THE RECOVERY TIMING FROM THE FAIL-SAFE MODE, THE LOGIC HAS BEEN CHANGED SO THAT THE DISTANCE-TO-EMPTY RECOVERS FROM “0” TO A NORMAL READING IMMEDIATELY AFTER THE FOREIGN MATERIAL IS DISLODGED (AT THE SAME TIME AS THE FUEL GAUGE).
