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.

The rear lift gate came open while driving on the freeway on ramp. No buttons were pushed to open the lift gate. I had to pull over to the side of the road to safely close the lift gate.

The manufacturer has deceived buyers concerning the towing capabilities: https://insidemazda.mazdausa.com/the-mazda-way/mazda-cx-50-offers-confident-towing-capabilities/ I bought the OEM tow hitch and wiring to achieve the advertised 3500 lb towing capacity, but according to the owners manual that is not possible as you are limited to 1000 lb without a brake controller which can not be purchased through Mazda. The trailer wiring and vehicle manual states that you must not modify it, which would be required to install a brake controller. I currently own a 2000lb trailer; I bought this vehicle specifically to pull it. There is no way to achieve this safely and legally despite the advertisements without aftermarket parts. If the required aftermarket brake controller install were to damage the vehicle's electrical system in some way, I doubt Mazda would cover that under warranty. The promotional material says nothing about non-OEM equipment first having to be installed in the car to achieve this tow limit safely. I'm sure the Mazda marketing department is well aware that this claim would make the CX-50 more appealing vs. it's competitors, however it is not accurate.
