2017 Fiat Fullback 2.4L Diesel · PF67 ABX

The Fiat Fullback presents a stable roadworthiness record in its most recent testing phases, with no defects logged on either of the December 2025 MOTs—one of which was a pass and the other a failure. The absence of advisories or defects in the 2025 tests suggests that, at the time of assessment, the vehicle met all DVSA thresholds for structural integrity, emissions, lighting, and critical mechanical systems. However, the repeated failures in December 2023 and 2025—both at identical mileages—raise an immediate question: the tester’s system flagged the vehicle as unroadworthy without specifying a reason, which is highly unusual. This inconsistency implies either a temporary administrative error or a minor but unrecorded issue that resolved itself before retesting. Given the lack of documented faults, the core mechanical systems appear to have been in order at the time of the latest inspection, but the buyer should treat the unexplained failures as a red flag warranting further scrutiny. The vehicle’s mileage accumulation—128,636 miles over nine years—indicates heavy usage, averaging around 14,300 miles annually, which is significantly above the UK fleet average for its age. The rapid mileage climb between tests is also notable: just 14,820 miles were covered in the year between the December 2023 and December 2024 MOTs, followed by another 18,820 miles in the subsequent 12 months. This pattern suggests either frequent long-distance driving or, less likely, a mileage discrepancy. The fact that the December 2025 tests occurred back-to-back at the same mileage further complicates the picture, as it implies the vehicle was not in motion during that period—or that the odometer was tampered with. Without additional service records, it’s impossible to verify whether this usage aligns with regular maintenance intervals, but the high mileage alone demands closer inspection of wear-prone components. For a prospective buyer, the primary focus should be on the suspension and drivetrain, given the vehicle’s age and mileage. The lack of recorded defects does not eliminate the possibility of hidden wear in coil springs, anti-roll bars, or ball joints, which are common failure points in high-mileage Fiats. Binding or uneven brake performance should be checked immediately, as the 2023 failures—though undocumented—could hint at a recurring issue with brake calipers, pads, or discs. Structural corrosion, particularly around wheel arches, sills, and exhaust mounts, is another critical area; the absence of rust advisories in the MOT history does not guarantee its absence, especially in regions prone to salt or moisture. Finally, the exhaust system and emissions controls should be tested for leaks or inefficiencies, as these are often overlooked but can lead to costly repairs if neglected. The vehicle’s clean MOT history is encouraging, but the unexplained failures and high mileage necessitate a thorough pre-purchase inspection by a qualified mechanic.
