When it comes to keeping your car roadworthy, the MOT test is a key milestone every year. But not all vehicles perform the same at the test centre. MOT pass and failure rates often vary significantly depending on the make and model of your car. In this article, we explore MOT passes vs fails by vehicle brand and highlight which cars tend to perform better in the UK.

Why Vehicle Brand Matters in MOT Results

Different car brands have different reputations when it comes to reliability, build quality, and durability. These factors often show up in MOT results. While age and mileage are big contributors to whether a car passes, the brand itself can play a role too.

Brands that focus on robust engineering and quality components often see higher pass rates. On the other hand, brands that cut costs on materials, or whose cars are more prone to wear and tear, may face higher failure rates.

Brands with Strong MOT Pass Rates

According to UK MOT statistics, certain premium and well-built brands regularly perform well. Brands such as:

• Honda – Known for reliability and longevity, many Honda models maintain strong MOT pass rates, even as they age.
• Toyota – Another brand praised for build quality, Toyota models often show fewer failures related to emissions or mechanical issues.
• BMW & Mercedes-Benz – Despite being more complex vehicles, these German brands tend to score above average in MOT tests, especially in their early years.
• Mazda – Lightweight but robust, Mazda’s engineering has helped it achieve consistent MOT success.

Brands That Struggle with MOT Failures

Not every car manufacturer fares so well. Some budget brands tend to see higher MOT failure rates, often due to cheaper materials, corrosion issues, or weaker components.

• Renault – Older Renault models frequently see failures in areas like suspension and brakes.
• Peugeot & Citroën – French cars are often criticised for electrical problems, which can affect MOT performance.
• Vauxhall – Popular in the UK, but some models have historically struggled with faults that show up during MOT testing.
• Fiat – While affordable, many Fiats see higher than average failure rates in areas such as lights, brakes, and steering.

The Role of Age and Mileage

While brand reputation plays a role, it’s important to remember that age and mileage are often bigger factors. Even reliable brands will fail if not serviced properly. For instance, a well-maintained ten-year-old Toyota may still pass, while a neglected three-year-old premium brand could fail.

What Drivers Can Do to Improve Pass Rates

Regardless of the car brand, drivers can improve their MOT outcomes with proper care:

• Regular servicing – Keep on top of oil changes, brake checks, and fluid levels.
• Pre-MOT inspection – Check lights, tyres, wipers, and washer fluid before the test.
• Act on advisories – If your MOT flagged an advisory last year, fix it before the next test.

Final Thoughts

When looking at MOT passes vs fails by vehicle brand, it’s clear some makes outperform others. Honda, Toyota, and German premium brands often shine, while certain French and budget marques struggle more often. That said, how you maintain your vehicle is just as important as the badge on the bonnet. Regular servicing and preparation remain the best way to ensure your car passes first time.
