The 2018 Giulia passes its MOT significantly more often than the UK average, with an 89.3% first-time pass rate against the national 80%, though nearly 30% of these cars have recorded a dangerous defect at some point—a concern worth taking seriously on inspection. Petrol models perform slightly better than diesels (90.4% vs 87.1% pass rate), suggesting the diesel variants may have more reliability quirks.

At 35,000 miles median for a six-year-old car, these Giulias are relatively lightly used, yet they still average 0.71 failures and 5.5 advisories per MOT visit, pointing to age-related wear rather than fundamental design flaws. If you're considering one, get a pre-purchase inspection that specifically flags any history of dangerous defects and brake/suspension work, since those are clearly the weak points.

The 2018 Alfa Romeo Giulia has a decent first-time pass rate (89.3%), 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 89.3% 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 5.5 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 1,577 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.
