What is the recurring trailer hitch wiring problem on the Mazda CX-50?
On 2023, 2024, and 2025 CX-50s equipped with Mazda Genuine Accessory trailer hitches, the wiring harness can detach and become damaged, causing trailer lights and brakes to fail. This increases the risk of a crash or trailer separation. Mazda issued recalls for these model years, so the harness repair is covered at no out-of-pocket cost.
