NHTSA Complaint #11646253 — 2019 MAZDA CX-5

The cylinder head on my 2019 Mazda CX-5 failed prematurely due to a known defect. The vehicle is currently at Fred Beans Mazda in Mechanicsburg, PA, where the issue has been diagnosed and confirmed. The defective component is available for inspection upon request. This failure created a serious safety risk due to an oil leak, which led to smoking from the engine bay and a potential fire hazard. If the oil had ignited, this could have caused severe vehicle damage or injury. Additionally, the failure could lead to a sudden loss of power while driving, increasing the risk of an accident. The problem has been reproduced and confirmed by the dealership, and Mazda has been contacted regarding assistance. They have acknowledged the issue but have not provided full coverage for the repair. Prior to the failure, there were no warning lights or messages. The only symptom was an oil leak, which led to smoke coming from the engine. This issue appears to be a common problem with this model, and Mazda should take responsibility for addressing it properly before it causes serious harm.
