Should I check the MOT history before buying a 2017 Infiniti Q50?

Yes. Look for recurring advisories — slow-building issues like corrosion or brake wear patterns show up years before they become failures. A full MOT history analysis will highlight patterns that a single test result won't reveal.

Check brake pipes, sills, subframes, and chassis legs. Surface rust is normal at this age; structural rust is a serious problem that is expensive to fix and can fail an MOT.

How are tyres and brakes typically on a 2017 Infiniti Q50?

Tyres and brakes are the most common advisory items on vehicles of this age. Budget for replacement if they are near the limit, and factor this into your offer price.

Moderate sample. 419 vehicles on record. Figures are indicative — the specific vehicle's history matters more than these averages.

The 2017 Q50 passes its MOT first time in 87.4% of cases, a solid 7.4 percentage points above the UK average, suggesting decent overall reliability. However, 40.1% of these vehicles have experienced a dangerous defect at some point, which is notably high and worth taking seriously when inspecting a used example.

These Q50s are running at 52,261 miles median—reasonable for a seven-year-old car—yet they're averaging 0.99 failures and 8.6 advisories per test, indicating wear is catching up with age. Before buying, get a pre-purchase inspection focused on the dangerous defect history, particularly around brakes and suspension, as this cohort shows elevated risk in those areas.

The 2017 Infiniti Q50 has a decent first-time pass rate (87.4%), but a higher-than-average share of vehicles have had serious defects recorded — the individual vehicle's history matters a lot here.

⚠️ Over 1 in 5 of these vehicles have had a dangerous MOT failure at some point — usually tyres or brakes, and often a one-off issue rather than a persistent problem. The group stats won't tell you which one you're looking at.

For context

✅ Good baseline reliability. A 87.4% first-time pass rate puts this well above the UK average — it's a well-sorted vehicle in this age bracket.

🔧 Expect consumable spend. An average of 8.6 advisories per vehicle tells you wear items (tyres, brakes) get flagged regularly. Budget for them — they're not surprises.

🔍 The dangerous defect figure is real. Most are one-off tyre failures or brake issues — not structural problems. But it's exactly why checking the individual vehicle's history is essential, not optional.

These stats describe 419 vehicles as a group. The specific vehicle you're looking at could be the one good example or the one outlier. Run its registration to find out.
