SummarySome vehicles may exhibit a deformed fuel-filler lid panel (1) attached to the fuel-filler lid box, resulting in a poor appearance. This concern is caused by the lid box not having enough water drainage capability which leads to the accumulation of water inside it. The water then freezes in cold weather and expands or the inner side of the lid panel absorbs the water and swells from long exposure, deforming the lid panel. To eliminate this concern, the shape of the fuel-filler lid box has been modified to have better drainage capability and a modified fuel-filler lid panel service part has been established for less water absorbance.

Phase 2 - A cushioning pad has been added to the hollow part in the liftgate weatherstrip (in addition to Phase 1 modification) for VINS greater than JM1BP*****313227 (produced after October 2, 2020)

To eliminate this concern, the PLG rear switch has been modified with a waterproof connector. Some Mazda3 customers may complain that the vehicle door locking system does not work when the door lock switch on the liftgate interior trim is pressed.

Water may enter through the rear center brand emblem base component and drip onto the switch connector causing corrosion. NOTE: The rusted connector may also cause a battery drain. To eliminate this concern, the rear center brand emblem base has been modified to prevent from water entry.
