What owners report
For the past 2 years there has been a severe parasitic battery drain issue that drains that battery partially or in some cases completely ruins new batteries. Car has spent a cumulative total of 3 months with a dealer trying to find the source. 5 batteries in 2 years and often times need to jump start the car. Car has been at dealer dozens of times and they have been unable to resolve issue. In looking online many others with same problems
The climate control system suffered a sudden, complete failure due to an engineering defect documented in Mazda Technical Service Bulletin (TSB) ID: MC-10203760-0001. The factory evaporator core leaked refrigerant rapidly starving the A/C compressor of essential lubricating oil. This caused the compressor to overheat and complete seize. This failure occurred during extreme summer heat exceeding 100 degrees Fahrenheit, creating an immediate health hazard inside the cabin during my daily 40-mile highway work commute. Additionally, the complete loss of climate control functionality compromises the vehicle's defogging and defrosting capabilities, creating a severe visibility hazard during sudden
Excessive oil consumption. Regularly have a low oil warning come up about 6000 kms after an oil change. Oil is always low when checked.
The vehicle experienced a premature internal A/C failure, resulting in a total loss of climate control refrigerant.

The manufacturer has issued Technical Service Bulletin (TSB) MC-10203760-0001 for factory evaporator defect on 2021 models, acknowledging low refrigerant charge due to component leakage. However, the manufacturer's current TSB VIN cutoff is too narrow. My vehicle is a 2021 model built at the same f
On June 3rd, 2026, about 1:15 PM, I braked in the rain because there was a stopped car in front of me. The brakes did not work; the Automatic Emergency brakes did not work; the Forward Collision Warning did not work and I hit the car in front of me causing a 3 car accident. As I hit the car I saw the Forward Collision Warning come on and then go out. Unfortunately, the brakes worked after that and the Mazda Collision Center cannot find anything wrong with the brakes. I note that the 2022 and 2023 models of the same car did have recalls related to the brakes. The claim is still open and I have not yet received the final damage report. Yesterday I was told the revised estimate is $16,000 and m
