2017 Hyundai Tucson 1.6L Petrol · RF66 WWC

A 2017 Hyundai Tucson showing 102,267 miles across eight MOT tests carries a generally consistent roadworthiness record, but the single failure on 20 December 2025 for excessive exhaust carbon monoxide content after the second fast idle introduces a meaningful powertrain concern that a prospective buyer must verify has been resolved. Five of the seven completed tests were clean passes with no advisories at all, including the most recent assessment on 3 January 2026, which suggests the exhaust-related defect was remedied promptly prior to retest. However, the fact that a 2017 Tucson exceeded manufacturer CO limits during emissions testing is not insignificant; on a 9 year old vehicle this can stem from a range of causes including a failing lambda sensor, degraded catalytic converter efficiency, air leaks in the intake or exhaust manifold, or fuelling irregularities, and any of these components should be specifically inspected before purchase. Annual mileage on this Tucson averages roughly 11,363 miles per year, which sits squarely within the expected range for a vehicle of this age and indicates a pattern of regular, moderate use rather than long periods of standing or unusually high accumulation. The annual test cadence from 2019 through 2026 shows continuous road use with no apparent gaps in MOT history, which reduces the risk of issues commonly associated with laid-up vehicles such as seized brakes, perished rubber components, or stale drivetrain fluids. Even so, at over 102,000 miles the Tucson is well into the territory where suspension linkages, engine and gearbox mounts, and general engine sealing components typically begin to show wear, so a thorough physical inspection remains essential despite the unremarkable annual mileage pattern. The advisory items recorded on earlier tests give a useful indication of what to examine during a test drive and pre-purchase inspection. The 2020 advisory noting front brake pads wearing thin is normal wear at that mileage and simply suggests confirming pad and disc condition now, with attention to any binding caliper feel or pulling under braking. More telling is the 2021 advisory flagging both front tyres worn close to the legal limit and the offside rear tyre exhibiting very uneven wear across the tread, as uneven rear wear on a Tucson can indicate rear suspension geometry issues, weakened torsion beam bushes, or alignment irregularities that may still be present. During a test drive, listen for clonks or knocking from the rear suspension over uneven roads and verify there is no wander or steering pull, particularly under braking. Given the 2025 emissions failure, the prospective buyer should specifically ask for evidence of what was repaired to bring CO readings back within limits, whether that involved a new lambda sensor, catalytic converter, or exhaust component, and ensure the corresponding invoice or warranty paperwork is available. On the road, the vehicle should be allowed to warm up fully before judging any rough idle or hesitation, and a cold-start observation is worthwhile as catalyst and sensor faults often present most obviously in the first few minutes of running. Inspect the underside for any oil residue around the engine and gearbox joints consistent with high-mileage sealing wear, check that all suspension components move freely without excess play, and confirm tyre wear is now even across both axles. With the emissions issue apparently resolved at the most recent test and no other structural or safety-related defects recorded across the MOT history, the mechanical foundations are reasonable, but the high overall mileage and the singular emissions failure mean a hands-on inspection and ideally an independent pre-purchase assessment remain strongly advisable.
