Mercedes Benz A (2019)
2019 Mercedes Benz A
CarHunch analysed 42,592 real MOT records for the 2019 Mercedes Benz A. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.
The 2019 Mercedes-Benz A passes its MOT first time at 90%, well above the UK average of 80%, which is a strong reliability signal—though nearly one in five have picked up a dangerous defect at some point, so pre-purchase inspection remains worth the cost. Petrol versions edge out diesels slightly (90.5% vs 89.3% pass rate), a small but consistent advantage.
At 30,702 miles median, these cars are running light for their age, suggesting many owners haven't punished them yet. The real story emerges in the details: 0.54 average failures per test is genuinely low, but 3.7 advisories per vehicle indicates minor wear is starting to accumulate—suspension, trim, and sensor issues rather than anything structural. Before committing, have a trusted mechanic check the brake discs, suspension bushes, and air suspension (if fitted), as these show up frequently in advisory records for this generation.
What to check before buying a 2019 Mercedes Benz A
Practical pre-purchase checks for this age and model.
- 📋 Check the full MOT history. Look for recurring advisories — slow-building issues like corrosion or brake wear patterns show up years before they become failures. Enter the reg below for a full AI analysis.
- 🔍 Inspect for corrosion in person. Brake pipes, sills, subframes, and chassis legs. Surface rust is normal at this age; structural rust is a serious problem that's expensive to fix and can fail an MOT.
- 🛞 Check tyres and brakes. The most common advisory items at this age. Budget for replacement if they're near the limit — factor this into your offer price.
- 📄 Run an HPI check. The MOT history won't show outstanding finance, insurance write-offs, or stolen status — an HPI check will.
