Should I check the MOT history before buying a 2018 Renault Grand Scenic?

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.

The 2018 Renault Grand Scenic passes its MOT at almost exactly the UK average rate of 80%, but a concerning 33.7% of vehicles in this cohort have recorded a dangerous defect at some point — well above the threshold you'd want to see in a family MPV. Petrol and diesel variants perform nearly identically, both hovering around 80% pass rate, so fuel type isn't a reliability differentiator here.

At a median mileage of 42,358 miles for a six-year-old car, these examples are running slightly light, which suggests some careful owners but also means higher-mileage used examples could be riskier. The average vehicle racks up 1.33 failures and 7.5 advisories per test, pointing to routine wear items and minor niggles rather than catastrophic issues — but that high dangerous-defect rate warrants a thorough pre-purchase inspection, particularly around braking and suspension systems.

The 2018 Renault Grand Scenic has a decent first-time pass rate (81.6%), 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

🔧 Average reliability. Passes at roughly the UK rate — not a standout, not a problem vehicle. Individual history makes all the difference.

🔧 Expect consumable spend. An average of 7.5 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 676 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.
