2025 Mazda 3 Coolant Leak

Some Mazda 3 owners report experiencing simultaneous high and low coolant light alerts along with the check engine light, indicating serious potential issues that require immediate attention. These alerts may suggest that the engine coolant temperature has risen excessively, while the low coolant light typically points to a low coolant level, both of which can lead to overheating and engine damage. Additionally, the check engine light may signal various problems, including issues with the engine's electrical system or emission control system, and ignoring it can result in further complications. Owners are advised to stop the engine immediately if these warning lights persist and have the vehicle towed to a qualified repairer, preferably an Authorized Mazda Dealer. Consulting a professional mechanic for diagnosis and resolution is crucial to ensure the vehicle's proper functioning and safety.

If the steering effort feels heavy, this can be caused by a power steering fluid leak. Some models may have burrs on the return port of the power steering reservoir that create a gap between the hose and the port. Sanding the burrs off the port and replacing the power steering return hose is the repair for this concern.
