NHTSA Complaint #11572935 — 2023 MAZDA CX-50

Keyless Entry: I have had this vehicle for about 6 months and over that time, more than 3 separate times the keyless entry hasn't unlocked. It may take 2 - 3 tries. It has never failed to eventually unlock. I don't know that it ever failed to lock because approaching the car it would have already been unlocked. I don't always hear it actuate. Auto-lock: I assume the same proximity system that is supposed to detect the keyless fob inside/outside at a distance - could be responsible for failure to auto-lock upon leaving the vehicle. Dependably securing vehicles is a major security problem is some areas and that is a major impetus behind keeping cars locked/and unlocking only as the driver approaches. Imagine being in a desolate parking garage late at night and the door chooses that particular moment to fail to cooperate. Or, if a driver trusts the auto-lock to work and it doesn't. App: In fairness, Mazda does have the MyMazda app that will eventually report to a phone that the car detects that it is unlocked. It seems unreliable. Currently the app has a "star rating" of about 1:10 3 or fewer for various issues. You can't make everyone nor every device cooperate - and to a degree, I can't say that's the problem. I would expect something wrong with the fob or proximity detection system. Just as likely, the door lock actuator has issues. Summary of Problem: Maybe about as many times, the app informs me the car is unlocked when it should have auto-locked. So is it a keyless, app or door actuator problem? Or, a combination? And, it works MOST of the time. I eventually asked myself if I would want someone's wife or kids out there and door locks fail at a critical moment. I must say, I haven't reported it formally because of the intermittent nature and the fact I have an issue with Mazda that has existed from the beginning. Major body parts are poorly fit and beyond contestation. If Mazda ignores that constant issue, an intermittent problem is likely to be as well.
