2016 Infiniti QX70 3.0L Diesel · LR16 UEV

The 2016 INFINITI QX70 presents a stable and largely positive maintenance trend across its MOT history. The most recent test, conducted on 25 June 2025 at 57,908 miles, resulted in a pass, confirming the vehicle met minimum safety standards at that point. However, the tester flagged corrosion on the central exhaust heat shields, a notable shift from the four preceding clean tests. This advisory suggests the onset of age-related deterioration in underbody shielding, a common issue on large SUVs that spend time standing or in damp conditions. The trend is therefore stable overall but with a minor emerging fault that warrants attention. The mileage pattern reinforces a picture of very light use. Between the June 2021 test at 38,047 miles and the June 2025 test at 57,908 miles, the vehicle covered just 19,861 miles over four years, averaging 4,965 miles annually. The most recent year shows a slight uptick to 5,646 miles, still well below the UK average. Such low annual accumulation typically reduces wear on consumables like brake discs, tyres, and suspension bushes, but it can mask problems caused by long stationary periods, including seized brake calipers, perished rubber components, and localised corrosion. The record shows no MOT gaps, meaning the vehicle has been tested annually without interruption, which is reassuring. Buyers should focus their physical inspection on the areas flagged in the most recent test and on components vulnerable to low-mileage deterioration. The corroded central exhaust heat shields need close examination; if severely degraded, they can detach or transfer heat to nearby fuel lines and underfloor wiring. Beyond that, check the condition of all brake components, as infrequent use can lead to binding calipers and uneven disc corrosion despite low mileage. Inspect suspension bushes, dust boots, and anti-roll bar links for perishing, and examine the underbody and sills for any structural corrosion beyond surface rust. The absence of advisories in earlier years suggests reasonable care, but the latest test indicates the vehicle is beginning to show its age.
