I have a 2010 Mazda 3 hatchback 2.5L. The hatch lock is unlocking and unlatching itself, sometimes continually. I will walk into the garage and hear just the hatch lock clicking/sliding itself. It will do it with no key in the ignition, with the car running in park but not if the car is driving. The door open light illuminates and the hatch will have to be pushed down to completely relatch. I removed batteries from both fobs think it was a remote issue but to no effect. It's just the hatch lock - not the door locks. If I disconnect the pushbutton from the lock, it stops. Any ideas?
