Unless Mazda or anyone can find a way to duplicate this, then I doubt they will comment. It also takes enough people to report it to Mazda for them to even look into it.I*ve had this happen twice in the two months that I*ve owned my 2018 GT CX-5. I keep my keys on a wall hook at my house and it is impossible that it is an accidental button push. Has Mazda commented on this issue?
Switch to the second key fob and keep the first one out of range. Do not change anything in your routine and see if it happens again. If it does, it is either a user problem, you have two defective fobs, or the auto-liftgate module or something in the electrical system (BCM?) is malfunctioning. Complain to a Mazda dealer, then call Mazda Corporate to get a ticket opened. Good luck.I just got my 2017 cx5 and my gate opened itself 3 times in 3 weeks in the parking lot..Nothing to do with me touching the remote..This is very concerning.
