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 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.
