2014 Infiniti QX70 3.0L Diesel · MT55 JHT

This 2014 INFINITI QX70 presents a stable and recently improving maintenance trend. The most recent test on 26 May 2026 at 92,026 miles passed with zero defects recorded, a clean sweep that also appeared in the July 2025 test at 90,329 miles. Two consecutive advisory-free passes indicate the vehicle is currently in sound mechanical order with no outstanding compliance issues. The mileage accumulation is consistent and unremarkable for a twelve-year-old SUV. Between November 2021 and December 2023 the car added roughly 16,000 miles over two years, then covered just under 1,700 miles in the eighteen months leading to the May 2026 test. That recent drop in annual mileage suggests lighter use or periods of standing, which can cause its own problems such as flat-spotted tyres or moisture ingress in the exhaust and braking systems, but the clean 2026 result suggests no lasting damage from the reduced usage. Earlier tests reveal a pattern of neglect around tyre condition that has since been addressed. In November 2021 at 71,262 miles all four tyres were flagged for cracking and perishing, and front and rear brake pads were noted as wearing thin. By November 2022 at 80,335 miles all four tyres again showed wear close to the legal limit with edge wear and tread cracking. The December 2023 test at 86,374 miles still flagged both rear tyres as worn close to the legal limit. The fact that no tyre or brake advisories have appeared since suggests the previous owner replaced these components, but a buyer should still verify the date stamps on all four tyres and inspect the remaining tread depth unevenly across each axle. Given the history of cracking tyres and worn brake pads, a prospective buyer should closely inspect the suspension bushes, coil springs, and damper seals for deterioration that often accompanies neglected consumable upkeep. The exhaust system and underbody should be checked for corrosion, particularly around mounting points and box sections, as standing periods can accelerate rust. A test drive should confirm the braking system pulls evenly and the steering tracks straight, ruling out any lingering alignment issues from the repeated edge wear flagged in earlier records.
