MAZDA Complaints

Driving vehicle on highway could not get the manual transmission into 3rd gear. Had to double clutch in order to do so. The vehicle only had 5,700 miles. The transmission produced a loud whining sound that could be heard outside the car. Took vehicle to dealership in which entire transmission was replaced.

Dear NHTSA Team, I am writing to formally report and follow up on a safety-related issue regarding my 2024 Mazda CX-90 PHEV, VIN: [XXX] . The vehicle has experienced repeated defects affecting critical safety systems, including: Engine overheating and cooling system failures Repeated engine malfunction warnings EVAP/emissions-related system faults These issues have persisted despite multiple visits to authorized Mazda service centers, and no permanent repair has been achieved. The defects raise serious concerns regarding the vehicle’s safety, reliability, and potential risk to road users. I have submitted a complaint via NHTSA’s Vehicle Complaint system but would like to confirm receipt and request the current status of my case, or any guidance on next steps. Please let me know if additional documentation, service records, or details are required. I am fully willing to cooperate to ensure this matter is properly reviewed. Thank you for your attention and assistance. Sincerely, Dr. [XXX] [XXX] Phone: [XXX] Email: [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Premature tire tread wear on 2025 Mazda CX-90 PHEV equipped with OEM Falken tires. At 21,586 miles, an authorized Mazda dealer measured tread depths at 5/32, 5/32, 4/32, and 3/32 (rear tire at replacement threshold). This level of wear is abnormal for the mileage and creates a safety concern due to reduced wet traction and hydroplaning risk. Dealer inspection dated 12/16/2025. Mazda USA case number 00394959.

Mazda has inspected the car and determined that there is a crack in the cylinder head. This is apparently a known defect in 2018-2021 Mazdas with 2.5L engines, including, without limitation, the 2018 Mazda CX-5. The cracked cylinder head has caused leaking coolant, which can drain into the engine and create serious safety issues. Mazda is aware of the issue, however, they are claiming that it is not covered by warranty.

I am reporting an unresolved safety-related defect with my Mazda CX-90. The vehicle began experiencing repeated malfunctions affecting reliable operation while being driven. The issue was reported to the dealer while the vehicle was still under the manufacturer’s original warranty. The vehicle was taken to a Mazda dealership for diagnosis and repair. The problem has not been resolved, and the vehicle has been held at the dealer for over 30 days. I was provided a manufacturer loaner vehicle because my vehicle has not been deemed reliable to return to service. Mazda North America has escalated the issue and informed the dealer that they are “waiting on Japan” for engineering guidance, indicating there is currently no approved repair or resolution. As of now, no permanent fix has been identified. This defect raises safety concerns because the vehicle’s reliability cannot be assured, and returning the vehicle to service without a confirmed repair could put occupants and others at risk. The extended out-of-service time and lack of an approved repair suggest a potential systemic issue. The vehicle remains available for inspection and is currently in the possession of the Mazda dealer. -

I brought my vehicle to Safford Mazda of Fredericksburg on Monday, December 15, 2025 due to a front-end clunking that occurs during left or right turns. A service representative test-drove the vehicle with me and was able to hear and duplicate the noise. Shortly afterward, I was informed that the front axle has internal damage and that the vehicle would need to be retained by the dealership for repair. I was told the necessary parts would not be available until sometime in February 2026. The dealership retained possession of the vehicle and arranged a loaner vehicle for my use. The service manager declined to provide written documentation stating that the car was unsafe to drive or describing potential consequences of continued operation. However, the vehicle was not released back to me pending the axle replacement. I have filed a complaint with Mazda Corporate, documenting the issue and the dealership's findings. A Mazda corporate case number is available if needed.

Steering became Notchy and in left turns only steering wheel would bind or stick when exiting a turn at a speed between 30 to 50 mph. Problem became significantly worse over course of a few days.

My Mazda 2021 infotainment screen goes goes out usually when hit a bump and stays out until it sits awhile. Which when this happens there is no backup camera which is a safety issue. The Mazda dealership said it was the screen which they wanted $2900 just for the screen so I got one off eBay and it's still doing the same thing. Which I think its the CMU
