MG Rv8 MOT Failure Rate

Q: What is the MOT failure rate for a MG Rv8?

The MG Rv8 has an overall MOT failure rate of 12.3%, based on 2,648 MOT tests in the DVSA database. This is below the UK average of 28%.

Q: What are the most common MOT failures on a MG Rv8?

The most common MOT failure areas for the MG Rv8 are: Lamps & Electrics (2.6% risk), Brakes (2.4% risk), Visibility (1.1% risk). These are based on weighted component failure rates across all age and mileage bands.

Q: Is the MG Rv8 reliable for MOT?

Yes, the MG Rv8 is more reliable than average for MOT, with a failure rate of 12.3% compared to the UK average of 28%.

Q: How does the MG Rv8 MOT failure rate change with age?

The MG Rv8 MOT failure rate increases with vehicle age. Newer models typically have lower failure rates, while vehicles over 10 years old see significantly higher rates, often above 35%. Regular maintenance becomes more important as your vehicle ages.

Q: How can I reduce the risk of my MG Rv8 failing its MOT?

Check all lights and bulbs, inspect tyre tread depth, test windscreen washers and wipers, listen for brake or suspension noises, and consider a pre-MOT check at a local garage. Use AutoSafe's free prediction tool for a personalised risk assessment.

What MG Rv8 Owners Should Watch For

Based on the MOT test data for the MG Rv8, here are the key areas to pay attention to before your MOT:

Lamps & Electrics (2.6% failure risk) — Walk around the car and check every bulb — headlights, brake lights, indicators, fog lights, and number plate lights. This is one of the cheapest and easiest fixes.
Brakes (2.4% failure risk) — Check brake pad thickness, disc condition, and handbrake operation. Listen for grinding or squealing when braking.
Visibility (1.1% failure risk) — Inspect windscreen for chips larger than 10mm in the driver’s line of vision and 40mm elsewhere in the swept area. Check all washers and wipers.

Many of these issues are inexpensive to fix when caught early. A pre-MOT inspection at a local garage typically costs £20–£40 and can save you the cost of a retest (£15–£30) plus the inconvenience of a failed MOT.

Frequently Asked Questions

What is the MOT failure rate for a MG Rv8?
