2012 Mitsubishi ASX 1.6L Petrol · SD12 VUP

The Mitsubishi ASX presents a mixed maintenance picture. The most recent test on 18 April 2025 at 128,053 miles passed, but the tester flagged corrosion on both the front and rear sub-frames, noting they were not seriously weakened at that time. This is a recurring theme. Structural corrosion advisories appeared in the 2024 test as well, covering the sub-frame and integral body structure. The trend is not worsening rapidly, but it is persistent. Brake pipe corrosion has been a recurring issue since at least 2021, when multiple pipes were flagged for corrosion under grease or other material. That problem escalated by March 2023, when three brake pipes failed the test for excessive corrosion. They were rectified before the April 2023 pass. The maintenance pattern suggests reactive repairs rather than proactive corrosion management, which is common on vehicles of this age but warrants careful inspection. The mileage accumulation is broadly typical for a 2012 vehicle. From the 2021 test at 91,297 miles to the 2025 test at 128,053 miles, the vehicle covered 36,756 miles across roughly four years, averaging approximately 9,189 miles annually. There is no evidence of extreme underuse or high-mileage abuse. The record shows consistent annual testing with no significant gaps, which is a positive indicator of regular use and at least baseline upkeep. A buyer should focus the physical inspection on the underside. The sub-frame corrosion advisories spanning 2024 and 2025 need close examination, particularly around mounting points and box sections where corrosion can hide behind surface coatings. Check whether the corrosion has progressed beyond surface level, especially given the vehicle is now over 14 years old. The brake system history is equally important. Although the brake pipes were replaced or repaired after the March 2023 failure, the original corrosion pattern suggests the vehicle may have been exposed to road salt or damp storage conditions. Inspect all visible brake lines, unions, and fixings for fresh corrosion or weeping. The rear brake fluctuation noted in 2024 also warrants a road test to confirm the rear calipers and discs are functioning evenly. Tyre condition has appeared as an advisory more than once, so check for uneven wear that could point to suspension or tracking issues, particularly given the anti-roll bar linkage dust cover failure flagged in the 2023 test.
