Mercedes-Benz Eqa 350 4Matic MOT pass rate & common failures
The Mercedes-Benz Eqa 350 4Matic appears in 1,228 MOT tests spanning model years 2021–2023, and 92.0% of them passed. That is effectively the same as all cars of a similar age (8.4% fail rate), so the MOT record here is unremarkable in either direction. Its most common failure areas are tyres, visibility and lighting & signalling.
What the MOT record shows
Tyres dominates the failure mix at 6.2% of all tests — 4.6 points clear of visibility, so it is the first thing to check.
At component level the recurring items are tread depth, headlamp aim and wipers — tread depth alone was recorded 16 times.
A 60-90k example is materially riskier than a 0-30k one: 11.1% versus 6.3%.
Advisories point at the next bill rather than this one: tyres was flagged on 22.1% of tests without failing them.

What to check before buying a Mercedes-Benz Eqa 350 4Matic
- Tyres (6.2% of tests): Usually a quick, known-cost fix, but check tread, age and uneven wear (which can hint at alignment or suspension issues). Typical repair: £50–£120 per tyre.
- Visibility (1.6% of tests): Wipers, washers, mirrors and screen damage — usually inexpensive, but check for chips in the driver's line of sight. Typical repair: £15–£150.
- Lighting & signalling (1.0% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
