Top MOT Failure Car

Data reveals a surprising leader in MOT failures this year: the Peugeot 307.

This model has shown a notably low pass rate, with just over half of the cars passing on their first attempt. Other models like the Citroen Xsara and Renault Grand Scenic also feature prominently in the list of frequent failures.

Age and maintenance issues are often culprits behind these failures.

What Is A MOT Failure Car?

An MOT failure car is one that doesn’t pass the mandatory annual MOT test. This test assesses vehicle safety, roadworthiness aspects, and exhaust emissions.

In 2018, the DVSA introduced three new, main categories for defects – minor, major, and dangerous. Major and dangerous defects lead to an automatic fail, highlighting issues that need urgent attention for the vehicle to be considered safe for the roads.

Read up more on the MOT Test changes with our complete guide!

  • Dangerous

    A ‘dangerous’ rating indicates a direct and immediate threat to road safety or a significant environmental hazard.

    The Driver and Vehicle Standards Agency (DVSA) cautions that a vehicle in this condition should not be operated until the necessary repairs are made.

  • Major

    A ‘major’ defect is characterised as one that could impact the vehicle’s safety, pose a risk to other road users, or have environmental consequences.

    The DVSA strongly advises that such defects should be repaired immediately.

  • Minor

    The ‘minor’ category represents issues that do not notably compromise the vehicle’s safety or have a substantial environmental impact.

    The DVSA recommends addressing these issues promptly, but a vehicle with a ‘minor’ defect will still pass the test.

  • Advisory

    An ‘advisory’ denotes a defect that could worsen over time.

    The DVSA advises monitoring this issue and undertaking repairs ‘if necessary’.

    Despite this advisory note, the vehicle will still pass the inspection.

  • Pass

    The last category, labelled as ‘pass’, indicates that the vehicle satisfies the minimum legal standards required.

    The DVSA recommends ongoing maintenance and checks to ensure the vehicle consistently meets these standards.

  • Key MOT Changes

    You must be aware of several significant changes to the MOT rules, encompassing new ratings. These changes are designed to enhance vehicle safety and environmental standards. Key updates include:

    1. Stricter Emission Limits for Diesel Cars: Diesel vehicles equipped with a Diesel Particulate Filter (DPF) now face more stringent emission limits. Suppose the MOT tester observes any smoke, regardless of colour, emanating from the exhaust or detects tampering with the DPF. In that case, the vehicle will incur a ‘major’ fault, leading to MOT failure.
    2. Dashboard Warning Light Defects: Any defect related to dashboard warning lights will be classified as a ‘major’ defect, resulting in MOT failure. This emphasises the importance of maintaining these systems in working order.
    3. Revised Brake Disc Classifications: There are updates in how brake discs are classified, impacting their assessment during the MOT test.

    Additionally, MOT testers will inspect several items previously not included in the test. These new inspection areas include:

    • Visibly under inflated tyres.
    • Contaminated brake fluid.
    • Fluid leaks that could harm the environment.
    • Brake pad warning lights and the absence of brake pads or discs.
    • Reversing lights for vehicles first used from 1 September 2009.
    • Headlight washers on vehicles first used from 1 September 2009.
    • Daytime running lights on vehicles first used from 1 March 2018 (this will become applicable from 2021).

    Finally, the Driver and Vehicle Standards Agency (DVSA) has made it mandatory to publish all faults classified as ‘dangerous’, ‘major’, and ‘minor’, along with any additional advisories from MOT testers, immediately after the MOT test is completed.

    This transparency ensures that vehicle owners and operators are fully informed about their vehicles’ condition and compliance with safety standards.

Top MOT Failure Areas

Brakes and tyres are common failure areas in MOT tests. Faulty brakes or worn tyres can lead to serious safety risks, hence their prominence in MOT checks.

Regular maintenance and checks can help car owners avoid these issues.

In other words, below are the top MOT Failure Locations.

    • Lighting and signalling is a common failure point with bulbs not working or being aligned incorrectly and are most common in older Vauxhalls (Corsas and Astras) and ford cars (fiesta and focus).
    • Worn-out suspension components with failures on excessive play in ball joints and worn bushes. Suspension failures are common in Volkswagen (polo’s and golf), and BMW (5 and 3 series).
    • Break failures include having insufficient braking efficiency, brake imbalance and worn discs or pads. Common in Renault (Clio and Megane) and Peugeot (206, 207)
    • Tyres and wheels tend to fail their MOTs most commonly with Nissan (Quashqai and Micra) and Fiat (Punto and 500) with the tyre tread depth being below legal limit, having uneven wear or damage to the tyre.
    • Exhaust and emission failures include exhaust leaks, catalytic converter issues or high CO2 emissions and are common in Volkswagen (Golf and Passat) and Audi (A4 and A3)
    • Visibility is another common failure that frequently occurs in Honda (Civic and Jazz) and Ford (Focus and Fiesta). Cars will fail their MOT for visibility due to windscreen wipers not working effectively and washer fluid not dispensing.
    • Steering: frequent failures include excessive play in the steering and power steering malfunctions and are common in Land Rover’s (Freelander, Range Rover)
    • Bodywork and structure issues tend to fail their MOTs with significant rust affecting the structural integrity or having damage to key areas, such as the seat belt anchor point.

Top Vehicle Brands With A Failed MOT

When it comes to brands, the differences are stark.

On a more positive note, the Lexus UX boasts an impressive first-time MOT pass rate of 95.4% in 2023, shining a light on the brand’s commitment to quality and reliability.

In contrast, American brands like Chevrolet and Chrysler have struggled, with more than half of their vehicles failing.

Regular servicing and the overall build quality of the cars play a significant role in these outcomes.

Below are some popular makes and models which are known to infamously fail their MOT.

  • Peugeot 307

    48.3% (5,521 tested)

  • Citroen Xsara

    48.4% (3,061 tested)

Why You Should Sell an MOT Failure Car

In such cases, selling the vehicle may be a sensible decision.

This is particularly true for older models, where repair costs can escalate quickly.

So, when spending the additional time, effort and money – Consider the end goal.
