2017 KIA Sorento 2.2L Diesel · AX17 DMF

This 2017 Kia Sorento presents an unusually clean DVSA record for a nine year old SUV, with four consecutive passes passed against its name across 2022, 2023, 2024 and 2025 and not a single advisory or defect entry recorded on any of those tests. The only blemish at all is the 2025-09-16 failed entry, which is immediately followed the very next day by a clean pass, strongly indicating that the failure was a minor administrative or presentation issue rather than a substantive mechanical defect, since the subsequent tester recorded no defects whatsoever. From a roadworthiness perspective, this is a reassuring pattern: the chassis, suspension, braking, exhaust, emissions and lighting systems have all been independently verified as compliant at the most recent test, with no wear progression documented over the four test cycles. A vehicle that consistently passes MOT scrutiny with no advisories typically suggests that consumable items such as brake pads, tyres, bushes and exhaust mountings have been replaced proactively before reaching the advisory threshold, rather than being left until the tester flags them. The recorded mileage of 110,525 against a 2017 registration places this Sorento at roughly 12,280 miles per year on average, which is at the higher end of typical private use and points to a vehicle that has spent a lot of time on the road rather than sitting on a driveway. The MOT testing cadence has been commendably regular, with annual tests each September from 2022 through 2025 and no significant gaps or lapsed periods that might suggest prolonged standing off-road. High annual mileage of this nature on a Sorento is generally well within the design tolerance of the vehicle, given that Kia engineered this generation for substantial service use, but it does mean that mechanical sympathy components have seen real-world work rather than gentle weekend use. Drivetrain wear, particularly on the four wheel drive transfer components, rear differential input and the multi-link rear suspension bushes, will accumulate proportionally with mileage, so the buyer should approach this car as a higher-use example rather than a low-mileage garage queen. For a prospective buyer, the absence of any recorded advisories on the MOT history means there is no specific component flagged for deterioration, but the mileage profile warrants a hands-on inspection of the areas most likely to have reached serviceable wear by 110,000 miles. On a test drive, listen for any clonking or knocking from the rear suspension over uneven surfaces, which would indicate worn trailing arm or upper/lower control arm bushes that have not yet reached the MOT failure threshold but may need replacement. Pay attention to steering precision and any vagueness around the straight-ahead position, as high mileage Sorentos can develop wear in the front subframe mounting points and anti-roll bar drop links. Brake pedal feel should be assessed for any sponginess, judder under heavy application, or pulling to one side, all of which would suggest binding calipers or warped front discs that have worn gradually with use rather than failing suddenly. Inspect the underside closely for any oil misting around the engine and transmission sumps, as well as any seepage from the power steering rack, since a vehicle at this mileage may have weeping seals that have not yet produced visible drips on the ground. Beyond the test drive, a few stationary checks will round off the picture. Cold start behaviour is particularly telling on a high mileage diesel Sorento, so listen for any excessive rattle from the timing chain area on initial ignition, along with any excessive smoke from the exhaust that does not clear within a few seconds. Confirm that all four wheel drive modes engage cleanly if exercised on a loose surface, and that the auto transmission shifts smoothly through all ranges without flare or hesitation, as both the transfer actuator and the torque converter are wear items that may be approaching serviceable life at this mileage. A compression test or a live diagnostic scan for stored fault codes, especially around the DPF, EGR and turbo actuator systems, would be a sensible precaution given the mileage, since diesel emissions components are subject to gradual soot loading that the standard MOT test does not always detect until a fault light is illuminated. With a clean MOT history behind it and a consistent testing record, this Sorento is a strong candidate mechanically, but a pre-purchase inspection from a Kia specialist or independent garage remains the prudent final step for any buyer considering a diesel SUV at this mileage band.
