Following the 2025 Mazda3 Sedan’s recommended maintenance schedule is the best way to preserve its performance, safety, and reliability over time. Always consult the vehicle’s owner’s manual or contact a certified Mazda dealership for detailed information and personalized service recommendations.

7,500 Miles or 6 Months

At 7,500 miles or six months, whichever comes first, the first service includes an oil and filter change to maintain optimal engine lubrication. Tires should also be rotated to ensure even wear, and a multi-point inspection should be performed to assess key systems, including brakes, suspension, and fluid levels. This initial check helps establish a baseline for the vehicle’s health and ensures it’s operating as intended.

15,000 Miles or 12 Months

At 15,000 miles or 12 months, the second service repeats the oil change and tire rotation while incorporating additional inspections. The cabin air filter should be replaced to maintain clean air circulation within the vehicle. The brake pads, rotors, and fluid levels should be checked for wear and topped off if necessary. The technician should also inspect the fuel system, including lines and connections, to identify any leaks or issues.

30,000 Miles or 24 Months

At 30,000 miles or 24 months, a more thorough maintenance interval is required. Along with the routine oil change and tire rotation, the engine air filter should be replaced to ensure proper airflow and maintain optimal fuel efficiency. Brake fluid should be inspected and replaced if needed to maintain the integrity of the braking system. Additional checks of the cooling system, belts, and hoses help prevent unexpected issues.

45,000 Miles or 36 Months

At 45,000 miles or 36 months, the maintenance schedule includes replacing the spark plugs to ensure smooth engine performance and efficiency. The technician should also examine the transmission system, including fluid levels, to ensure proper shifting and long-term reliability. Routine oil changes, tire rotations, and system inspections continue during this interval.

60,000 Miles or 48 Months

At 60,000 miles or 48 months, the transmission fluid should be replaced to maintain smooth shifting and prevent premature wear. A complete cooling system inspection and coolant replacement are recommended to keep the engine operating at the correct temperature. The suspension system and steering components should also be checked for wear, ensuring the vehicle remains safe and responsive.

120,000 Miles or 96 Months

At 120,000 miles or 96 months, the maintenance schedule includes a more extensive inspection of the engine and drivetrain components. This interval typically involves replacing the timing belt (if applicable) or inspecting the timing chain to prevent potential engine damage. A comprehensive review of all major systems, including the brakes, cooling system, and suspension, ensures the vehicle continues to perform reliably.

Severe Driving Conditions

For drivers operating the Mazda3 Sedan under severe conditions—such as frequent stop-and-go traffic, extreme temperatures, or dusty environments—Mazda recommends more frequent maintenance. This includes shorter intervals for oil changes, air filter replacements, and brake inspections to accommodate the added strain on the vehicle.

Additional Service Tips

Brake fluid should be inspected every two years or 30,000 miles, even if no specific issues are evident. The battery should be tested annually, particularly in regions with extreme climates, to ensure reliable starting power. Windshield wipers should be replaced every 12 months or as needed to maintain visibility, and tire pressure and tread depth should be checked regularly to ensure safety and fuel efficiency.
