2017 Fiat 500X 1.6L Diesel · ML10 AND

The 2017 Fiat 500X presents a solid baseline of structural integrity, having passed four consecutive MOTs between March 2023 and January 2025 with zero defects recorded. However, the most recent test on 5 January 2026 reveals a notable shift in maintenance standards. At 95,326 miles the vehicle failed on excessively deteriorated track rod end ball joint dust covers on both front wheels, a defect that allows ingress of dirt and moisture, accelerating wear on the joint itself. The tester also flagged both rear brake discs as worn, pitted, or scored, and the nearside front tyre as worn close to the legal limit. These items were rectified, and the car passed on the same day at 95,328 miles. The trend is therefore worsening compared to the previous four years of clean passes, suggesting basic preventive upkeep was neglected in late 2025 or early 2026. The mileage accumulation is entirely consistent with typical use for a nine-year-old vehicle. Between 74,034 miles in March 2023 and 87,649 miles in January 2025, the car covered 13,615 miles in roughly 22 months, then added 7,679 miles in the 11 months leading to January 2026. That equates to approximately 10,600 miles per year, which is unremarkable for a petrol crossover of this age. There are no suspicious gaps or sudden spikes in the odometer record that would raise concerns about tampered mileage or prolonged standing. The recurring theme across the January 2026 test is neglect of consumable wear items rather than a single catastrophic failure. Both rear brake discs were flagged simultaneously, which often points to a lack of routine inspection or a binding caliper issue that went unaddressed long enough to cause pitting and scoring. Buyers should inspect the rear braking system carefully, checking disc thickness, pad condition, and caliper slide pins for free movement. The track rod end dust cover failure on both sides is a red flag for suspension and steering health. Once those covers split, the joint is exposed to road grit, and play can develop quickly. A physical check of the inner tie rods and rack boots is essential, along with a road test to detect any vague or clunky steering feel. Tyre wear on the nearside front reaching the legal limit at 95,328 miles suggests uneven wear patterns, possibly from misaligned tracking or a lack of rotation. A buyer should measure tread depth across all four tyres and inspect the inner edges of the front pair for feathering or camber wear. The clean MOT history prior to 2026 indicates the car was not abused, but the sudden cluster of defects at the latest test implies the previous owner deferred basic maintenance. A thorough underbody inspection for corrosion, particularly around rear suspension mounting points and subframes, is advisable before purchase.
