Consumer Description

The vehicle was leaking coolant. The Mazda dealership Technician concluded it was a cracked radiator. There was no warning sign. Took vehicle in for an oil change and that's when the problem was discovered. Mazda completed service with replacing a new radiator on 2/12/26. On 2/15/26 the coolant is burning in/on engine. Reservoir is completely empty after being capped off during service. I believe the new radiator has cracked again. The vehicle didn't show a rise in temperature which would allow a driver to continue driving with this issue until they have a major engine failure due to lack of coolant in the system.
