2015 Mazda 3 2.0L Petrol · SR64 CCE

The vehicle is currently roadworthy following a January 2026 test, but the maintenance history reveals a worsening trend regarding structural and hydraulic corrosion. While the car passed its most recent inspection at 59,298 miles, it failed just one mile prior due to a fractured offside rear coil spring and multiple brake pipe defects. The persistence of significant corrosion across the sub-frames and suspension components indicates that the vehicle is subject to ongoing environmental degradation that remains unaddressed despite passing the test. At 59,298 miles over eleven years, the Mazda shows notably low annual mileage, averaging approximately 5,400 miles per year. This low usage often correlates with the issues observed here, as vehicles that sit stationary are prone to accelerated corrosion and seized components. The data shows a consistent pattern of roughly 3,000 miles driven between annual tests from 2024, 2025, and 2026, suggesting the car is not under heavy use but the low mileage has not prevented the effects of age on the undercarriage metalwork. A buyer must conduct a thorough physical inspection of the front and rear sub-frames to assess the depth of the rust noted by the tester. The record shows recurring failures for corroded brake pipes that are frequently covered in grease, which may be an attempt to hide the extent of the metal decay. Particular attention should be paid to the rear suspension for further signs of fatigue, given the fractured coil spring identified in 2024 and 2026. The previous report of overheating brakes in 2024 also suggests a potential binding caliper or a sticking piston that should be verified to ensure the braking system is operating correctly.
