The 2014 Mercedes-Benz GLA passes its MOT significantly more often than the UK average, with an 88.7% first-time pass rate versus 80%, but nearly 28% of these cars have recorded at least one dangerous defect—a real concern for safety-conscious buyers. Petrol versions do slightly better at 91% pass rate, though the larger diesel cohort sits at 88.3%, suggesting fuel type makes little practical difference here.

At around 55,000 miles for a ten-year-old car, these GLAs show typical mileage, and the 1.22 average failures per vehicle indicates modest repair needs when things do go wrong. The high advisory count of 8.3 per car points to wear items and minor issues cropping up regularly, so budget for preventive maintenance and have any potential purchase thoroughly checked for those dangerous defects before committing.

The 2014 Mercedes Benz Gla has a decent first-time pass rate (88.7%), 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 88.7% 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 8.3 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 3,755 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.
