2017 Toyota C-HR 1.2L Petrol · WN67 ACY

The 2017 Toyota C-HR has demonstrated a mixed but largely stable roadworthiness pattern over its MOT history, though the most recent test in October 2025—just eight months ago—revealed a persistent coolant leak, a critical advisory that was not addressed before the test. This suggests either deferred maintenance or an ongoing issue with the cooling system, potentially indicating heat-related stress on the engine or transmission. Earlier tests in 2024 and 2023 were clean, but the 2022 and 2021 records show a troubling trend of repeated tyre failures, with four of six tyres flagged for tread wear or damage, including perishing and edge wear. The 2021 test also uncovered a structural concern: the missing undertray and loose wheel arch liners, which—while not immediately dangerous—demonstrate neglect of bodywork integrity. The brakes have shown consistent wear, particularly on the front discs and pads, though none have reached a fail threshold. Overall, the vehicle has passed all tests but has not been maintained with the consistency required to prevent recurring issues. The mileage progression suggests moderate usage, averaging around 9,400 miles annually, which is typical for a vehicle of this age. There are no extreme gaps or spikes in mileage between tests, though the 2021 to 2022 interval (11,996 miles in 12 months) is slightly higher than the subsequent years. The most notable pattern is the concentration of tyre-related advisories in 2021 and 2022, followed by a reduction in such issues in later tests, which may imply either tyre replacements or improved monitoring. However, the coolant leak in 2025—without prior mention—indicates a recent or lingering problem that warrants immediate attention. The absence of any fail categories in the 2023 and 2024 tests contrasts sharply with the earlier record, suggesting either a period of better maintenance or a vehicle that was running reliably until more recent wear set in. A prospective buyer should prioritise a thorough inspection of the cooling system, particularly the radiator hoses, expansion tank, and engine bay for signs of leaks or corrosion, as the 2025 advisory suggests this is not a one-off issue. The tyres, despite passing recent tests, show a history of neglect—particularly the rear tyres in 2021 and 2022—which could indicate uneven loading or suspension misalignment. Check for uneven wear patterns, tread depth consistency, and any signs of perishing or cracking on all four tyres. The brakes, while not currently failing, have shown consistent wear on the front discs and pads; verify that the calipers are not binding and that the discs are not excessively scored or warped. Finally, inspect the undertray and wheel arch liners for any signs of rust or further loosening, as the 2021 advisory suggests potential structural vulnerabilities that could worsen over time.
