Summary
Some CX-5 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 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 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 washer. 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.

Owners of these vehicles have filed 1 complaints in the locks category.
