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 failinga”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: a¢The reliability of Mazdaas factory parts a¢The quality and safety of refurbished transmissions Mazda uses in warranty repairs a¢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.
