I OWN 2020 MAZDA CX 30 WITH 66000 MILES. THE TRANSMISSION WAS SHIFTING WITH JERKY MOTIONS. ON JULY 14, 2025 I BROUGHT THE CAR TO PALISADES MAZDA IN ROCKLAND COUNTY NEW YORK TO HAVE TRANSMISSION LOOKED AT AND TO CHANGE TRANSMISSION FLUID CHANGED. AFTER I DROPPED THE CAR OFF LATER THAT DAY I GOT A CALL THAT THE TRANSMISSION WAS CONDEMNED. I LOOKED ON THE INTERNET WITH SAME YEAR MAKE AND MODEL AND SEE THERE IS A BIG PROBLEM WITH THE TRANSMISSIONS ON THESE CARS AND MAZDA IS AWARE OF THE PROBLEM. TSB 05-002/20 IS A BULLETIN ABOUT TRANSMISSION FAILURES IN THIS VEHICLE. MAZDA IS WELL AWARE OF THE TRANSISSION PROBLEMS

The initial sensor alarm indication was low oil pressure and within less then an hour engine malfunction was detected and the vehicle stopped functioning. This incident occurred on [XXX] in SanAntonio and thereafter it was towed to the Mazda Dealership for inspection upon request. I was driving from Dallas to SanAntonio with my [XXX] and [XXX] children when the vehicle started making strange noise and It the notification on dashboard stated I need to immediately stop the vehicle for safety. Middle of nowhere I had to find a nearest safe place for my children. This vehicle put me and my kids in an unsafe environment due to the faulty engine that was installed by the Mazda company. I was afraid thinking the car will start on fire because it was an engine alert. Yes the vehicle has been inspected by the North Park Mazda dealership on 5/12/25 with an initial quote of engine repair for $7905.88. The first time I noted which was few weeks back prior to this incident when the vehicle stalled at me while I arrived and stopped the vehicle at UT Southwestern Medical Center were I work as a nurse to badge into my parking lot. I got worried for a moment thinking could it be battery issue? I turned off the vehicle and turned it back on and the vehicle starting working. I parked the car and completed a 12 hr shift and thereafter did few weeks of work without any alerts or issue on the vehicle until the day off [XXX].

I am reporting a repeated and potentially dangerous transmission failure in my 2020 Mazda CX30. At 6 months old, the original transmission failed. Mazda confirmed it was defective and replaced it with a refurbished unit with 10,000 miles on it. That replacement is now also failing—within 4 years of the first failure. This means the car has experienced two transmission failures before reaching 5 years of service. This raises concerns about: •The reliability of Mazda’s factory parts •The quality and safety of refurbished transmissions Mazda uses in warranty repairs •A potential pattern of premature transmission failures on this model Repeated transmission failure can cause loss of power and control, posing serious safety risks to drivers and passengers. Mazda has all service records confirming both incidents. I am submitting this to alert NHTSA to a possible defect pattern that may warrant investigation.
