2015 Mitsubishi ASX 1.6L Petrol · WF15 LKZ

The Mitsubishi ASX presents a mixed maintenance picture. The most recent test on 22 May 2026 at 63,666 miles passed, but the tester flagged a corroded offside rear coil spring, a repeat of the defect noted in the 2025 test at 57,308 miles. This recurring suspension corrosion points to a worsening trend rather than a one-off issue. The vehicle sat clean on the two prior tests in 2023 and 2024, so the corrosion has developed or worsened noticeably within the last two years. The maintenance pattern is therefore stable overall but declining in one specific structural area. The mileage profile is low for an 11-year-old vehicle, averaging roughly 5,788 miles per year. The record shows a gap between April 2023 at 43,251 miles and May 2024 at 49,838 miles, covering 6,587 miles in just over twelve months, followed by a jump to 57,308 miles by May 2025 and 63,666 miles by May 2026. Mileage accumulation has accelerated in recent years, suggesting the car has moved from light use to more regular driving. No tests are missing from the annual cycle, so the record is complete and consistent. The repeated corrosion on the offside rear coil spring is the most significant finding. A corroded coil spring carries a risk of sudden fracture under load, particularly over speed bumps or uneven surfaces. A buyer should have the full underside inspected with the vehicle on a ramp, paying close attention to the condition of both rear coil springs, the front springs, and all suspension mounting points for rust jacking or perforation. The rear brake pads were noted at approximately 3 mm in 2025, so pad thickness and disc condition should be verified. The 2025 test also flagged perishing on three tyres, meaning the current tyre age, sidewall condition, and date codes need checking to confirm replacement has taken place. Given the low annual mileage, long periods of standing may have contributed to localised corrosion and rubber deterioration, so brake fluid condition and corrosion along brake lines and exhaust mounting points also warrant close inspection.
