2023 Mazda cx50 with 28k miles. This vehicle was purchased 3mths ago. The cx50 has locked me out 5 times & had a dead battery each time. Has been to dealership 3 times. No repairs made after dealership doing battery drain extensive testing. Cycle of this happening 3 times. I’ve been in a loaner more than my purchased vehicle. It is a safety concern leaving me locked at of my vehicle 5 times. Then when gaining access to vehicle with manual key. Vehicle has had dead battery 5 times all of this occurred over 3 months. With no repairs made from dealerships. It’s been to two different dealerships. Major safety concerns! The dealership has agreed to buyback the cx50. But it has taken a lot of phone calls with dealerships & Mazda corporate. Vehicle is still currently owned by me & awaiting buyback to occur this week. Not a safe vehicle!!! No warning lights no signs of any kind & battery continues to be dead. Battery changed twice by dealership. No other repairs done.

I am reporting a potential airbag system/emergency brake failure in my 2023 Mazda CX-50. I was involved in a rear-end motor vehicle accident at approximately 60 mph while my vehicle was completely stopped. I then hit the person in front of me. At the time of the impact, the airbags did not deploy, and I received a dashboard message indicating an airbag system malfunction. Since then, the emergency brake turns on and off on it's own at any time. Due to the severity of the crash, I am concerned that the airbags should have deployed, and their failure raises a serious safety concern. I sustained injuries (multiple fractures) as a result of the collision. I am requesting a formal investigation into possible defect or malfunction in the airbag system and emergency brake system.

While driving 72mph on the interstate at 6am on 7/21/26 the sunroof exploded. No foreign objects made impact with the vehicle and there was no sudden temperature shifts. The glass had no previous defects and it shattered into tiny pieces, failing into the car. The sun shade was open at the time. The vehicle is being serviced at a glass repair shop who noted this is a common issue with Mazda sunroofs.
