MG 4 Se: MOT pass rate and reliability data

The MG 4 Se passes its MOT first time more often than the average UK car, by 17.2 percentage points. These figures come from the DVSA's full year of anonymised MOT results, covering 677 individual MG 4 Se tests. Nothing here is an estimate or a survey.

The numbers

What this means if you are buying one

A 93.9% first-time pass rate means roughly 6 in every 100 MG 4 Ses presented for MOT fail on the first attempt. That is better than average, so a well-kept example is a reasonably safe used buy. The average MG 4 Se tested had covered 22,264 miles and was built around 2023.

What this means at salvage auction

Pass rate is a proxy for what a car costs to keep on the road. The MG 4 Se sits 17.2 points above the national average, ranked 152 of 2,005 models. On one bought as repairable salvage, the mechanical side is less likely to spring surprises, so your repair estimate should hold up reasonably well.

Before you bid: run the lot through the analyzer, check the car's own record, check the mileage, decode the VIN, and if it carries a marker use the write-off value calculator. Or compare it against another model.

Looking at a specific MG 4 Se rather than the model in general? The free check covers its MOT and mileage history, and the full HPI report confirms the insurance write-off category, outstanding finance and whether it is recorded stolen, from licensed data for 5 credits. Already own one that has been damaged? Work out whether fixing it beats selling it with the repair or scrap calculator, and see recorded closing bids for damaged MG 4 Ses at UK salvage auction.

Most common MOT advisories on a MG 4 Se

An advisory doesn't fail the car - the tester flags it as worth watching, but it still passes. A different list from the failures above: what testers are noting on a MG 4 Se before it actually fails on it.

1. Tyre tread depth not in accordance with the requirements, 25.3% of tests, also fails
2. A tyre seriously damaged, 7.5% of tests, also fails
3. Excessive fluctuation in brake effort through each wheel revolution., 0.3% of tests
4. Fluid leaking excessively and likely to harm the environment or to pose a safety risk to other road users, 0.1% of tests
5. An obstruction significantly affecting the driver's view of the road through the swept area of the windscreen or an obligatory external mirror not visible, 0.1% of tests (1.8x the national rate for this advisory), also fails
6. A suspension pin, bush or joint excessively worn, 0.1% of tests
7. Brake disc or drum excessively weakened, insecure or fractured, 0.1% of tests
