Manufacturer summary
Original wording in English
Some CX-5 and CX-30 customers may find that the liftgate does not close when pressing the power liftgate (PLG) rear switch (A) located on the interior liftgate trim. This may be caused by PLG switch corrosion. Water from a high pressure car washer and/or condensation may drip onto the switch connector and cause corrosion. To eliminate this concern, the PLG rear switch has been modified with a waterproof connector. Some Mazda3, CX-30 and MX-30 customers may complain that the vehicle door locking system does not work when the door lock switch on the liftgate interior trim is pressed. DTC B11C4:23 (BCM - liftgate lock switch circuit malfunction) may be stored. This may be caused during a high pressure car wash and/or condensation. Water may enter through the rear center brand emblem base component and drip onto the switch connector causing corrosion. The rusted connector may also cause a battery drain. To eliminate this concern, the rear center brand emblem base has been modified to prevent water entry (Mazda3) and the rear harness has been modified to prevent water infiltration (Mazda3, CX-30 and MX-30).
