MG 6: MOT pass rate and reliability data

The MG 6 fails its first MOT more often than the average UK car, by 9.7 percentage points. These figures come from the DVSA's full year of anonymised MOT results, covering 1,882 individual MG 6 tests. Nothing here is an estimate or a survey.

The numbers

What this means if you are buying one

A 67% first-time pass rate means roughly 33 in every 100 MG 6s presented for MOT fail on the first attempt. That is worse than average, so budget for remedial work and treat a fresh 12-month MOT as a genuine selling point rather than a given. The average MG 6 tested had covered 71,312 miles and was built around 2014.

What this means at salvage auction

Pass rate is a proxy for what a car costs to keep on the road. The MG 6 sits 9.7 points below the national average, ranked 1,828 of 2,005 models. On one bought as repairable salvage, assume the mechanical side needs more than the visible accident damage, and pad your repair estimate accordingly.

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 6 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 6s at UK salvage auction.

Most common MOT failures on a MG 6

1. Brake pipe damaged or excessively corroded, 12.2% of tests (11.39x the national rate for this defect)
2. A suspension component excessively damaged or corroded, 2.9% of tests (8.37x the national rate for this defect)
3. A tyre pressure monitoring system malfunctioning or obviously inoperative, 2% of tests (7.19x the national rate for this defect)
4. A wheel with a loose or missing wheel nut, bolt or stud, 2.1% of tests (6.71x the national rate for this defect)
5. A headlamp or light source missing, inoperative or more than ½ not functioning in the case of LED, 3.7% of tests (2.99x the national rate for this defect)
6. A direction indicator lamp missing, inoperative or in the case of a multiple light source more than 1/2 not functioning, 1.9% of tests (2.92x the national rate for this defect)
7. A suspension pin, bush or joint excessively worn, 11.4% of tests (2.26x the national rate for this defect)
8. The aim of a headlamp is not within limits laid down in the requirements, 4.3% of tests (1.81x the national rate for this defect)

From 1,881 DVSA-tracked MG 6 tests, 2024. DVSA testers marked 5.51% of these flagged MG 6 defects as "dangerous", meaning the tester judged the car unsafe to drive away, against 5.11% nationally.

Most common MOT advisories on a MG 6

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 6 before it actually fails on it.

1. Brake pipe damaged or excessively corroded, 35.2% of tests (5.68x the national rate for this advisory), also fails
2. A suspension component excessively damaged or corroded, 24.6% of tests (4.76x the national rate for this advisory), also fails
3. A spring or spring component fractured or seriously weakened, 13.8% of tests (2.91x the national rate for this advisory)
4. Product on the lens or light source which obviously reduces light intensity or changes emitted colour to other than white or yellow, 1.9% of tests (1.73x the national rate for this advisory)
5. Brake disc or drum excessively weakened, insecure or fractured, 18.6% of tests (1.52x the national rate for this advisory)
6. a brake lining or pad worn below 1.5mm, 12.4% of tests (1.33x the national rate for this advisory)
7. Tyre tread depth not in accordance with the requirements, 34.7% of tests (1.3x the national rate for this advisory)
8. Brake disc or drum significantly and obviously worn, 4.1% of tests (1.29x the national rate for this advisory)
9. A brake hose ferrule excessively corroded, 1.6% of tests (1.25x the national rate for this advisory)
10. The strength or continuity of the load bearing structure within 30cm of any sub-frame, spring or suspension component mounting (a 'prescribed area') is significantly reduced or inadequately repaired, 1.9% of tests (1.23x the national rate for this advisory)
