2023 MAZDA CX-50 Complaints

Car has under 14k miles on it. There have been 2 instances going from a stopped to rolling with no foot on the accelerator to turn sharply out of a parking lot where when turning sharply to maneuver the vehicle surges forward and accelerates quickly on its own. It is concerning because both times I was in a small, confined area making turns out of a lot. I do not want an accident to occur due to this issue.

The Collision Avoidance System did not activate, to avoid a front-end collision. The vehicle in front of me stopped, making a right-hand turn onto another road. I moved forward, not seeing him stop. My car rear-ended the vehicle in front of me, with no warning or activation from my system.

I was hearing squealing, as if the brake pads were worn. Called the dealer to ask about parts, was asked to bring it in as it seems too soon for brakes. Upon inspection I was told my rear brakes are worn out at 22k highway miles, and will need rotors too. I asked how this is possible and for a manager whom then stated I could do just the pads. Still no explanation on how, but won't be covered on the warranty. I left without doing the repair because I wanted another mechanic to look at this since you can only get the rear pads from Mazda, so it's expensive. I do need this done and I believe there is a problem with the brake system or the electronic brake you hear engage Everytime you shut the car off. There are also several others complaining about this on Reddit, Google and YouTube, but Mazda seems to be looking the other way in it. I can say this is my 12th Mazda and I have never had one that has needed brakes before 60-70,000 miles and that was with city driving. There is clearly an issue and I'm not the only one.

Emergency braking activated with no obvious scenario that would engage it. On different occasion, emergency braking activated in stop and go traffic, causing extreme deceleration resulting in engine stalling.

Vehicle was purchase new, experienced safety concerns front brakes driver and passenger leaking brake fluid near brake calipers no warning lights. Fluid in the reservoir got pretty low. Pending case with Mazda USA. Local dealer stated over the phone was not covered because out of warranty 47,000 miles 2023 CX-50 Turbo mostly highway miles this vehicle was purchased as daily driver.

Leaking water in the rear right/left sides from the roof when raining resulting in mold growth inside the roof and hidden areas of the roof / car.

Rain water leaking into interior body of vehicle. Water pools up between the headliner and interior body of vehicle. Mold starts to form on headliner fabric and in unseen places on the interior. Safety concern is mold. Living in warm humid tropical climates is asking for serious issues. Symptoms of mold: itching, coughing, wheezing, difficulty breathing, headache, and fatigue. A simple google search shows many owners coming forward online about the same issue happening in the exact location of each Mazda CX50. It’s too specific to ignore. This is being reproduced by dealerships and in other vehicles daily. (Look online, Reddit, Mazda forums.) The warning signs have been mold growing on fabric and water inside vehicle after rain. This is happening to 100s of CX50s.

The contact owns a 2023 Mazda CX-50. The contact stated that while in a parking lot, the steering wheel was moving to the left and the right. The contact stated that the wheel was wobbling. There were no warning lights illuminated. The vehicle was taken to a local dealer, where it was diagnosed that the steering wheel bolt was loosened. The vehicle was repaired. The manufacturer was contacted, but no assistance was provided. The failure mileage was approximately 75,500.

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 key light went on without me knowing what it was. Brakes are taking a while to engage. The acc stoped my car while driving in traffic almost caused an accident. Don’t know if this matters but phone charger does not stay connected with cover or not.
