Most common owner-maintenance faults

DVSA wording grouped as owner maintenance for this model and age band.

  1. 1

    Tyre worn close to legal limit/worn on edge

    438,899 notes5.2.3 (e)
    What it means, why it happens, what to check

    What it means

    Tread is close to (or at) the legal minimum, or wear is concentrated on an edge. That often points to alignment, pressure or suspension issues as well as simple age.

    Why it happens

    Under-inflation, poor alignment, aggressive driving or simply delayed replacement push tread below a safe/legal profile.

    Buyer tip

    Measure tread across the full width, check tyre age (DOT date) and look for uneven inner-edge wear.

    Severity

    Usually maintenance related
  2. 2

    Headlamp aim too low

    23,169 notes4.1.2 (a)
    What it means, why it happens, what to check

    What it means

    This MOT defect usually indicates incorrect headlamp alignment following adjustment, suspension movement or repair work.

    Why it happens

    Aim drifts after suspension work, bumper repairs, bulb changes or simply from road vibration over time.

    Buyer tip

    Check beam alignment during inspection and ask whether the lamps were aimed after any recent suspension or bodywork.

    Severity

    Usually maintenance related
  3. 3

    Windscreen washer not working

    15,562 notes3.5 (a)
    What it means, why it happens, what to check

    What it means

    Washer jets are not delivering fluid. Testers need a clear screen; empty reservoirs, blocked jets or failed pumps are common.

    Why it happens

    Empty bottles, frozen/blocked jets, split pipes or a failed pump stop fluid reaching the screen.

    Buyer tip

    Top up fluid, test the jets on the driveway, and check for cracked bottles or split pipes in the engine bay.

    Severity

    Usually maintenance related
  4. 4

    Shock absorbers has light misting of oil

    15,283 notes5.3.2 (b)
    What it means, why it happens, what to check

    What it means

    A damper mounting bush is worn, which can cause knocks, vague handling and accelerated tyre wear.

    Why it happens

    Rubber bushes harden and tear with age, road salt and repeated suspension movement.

    Buyer tip

    Listen for clunks over speed bumps and have a mechanic check top mounts and lower bushes.

    Severity

    Usually maintenance related
  5. 5

    Tyre pressure monitoring system malfunctioning or obviously inoperative

    8,832 notes5.2.3 (h)
    What it means, why it happens, what to check

    What it means

    The tyre pressure monitoring system is reporting a fault or is clearly not working, so you may not get a dashboard warning of under-inflation.

    Why it happens

    Flat battery sensors after tyre changes, damaged valves or control-module faults are common.

    Buyer tip

    Confirm whether sensors need replacing after recent tyre or wheel work, and check pressures manually anyway.

    Severity

    Usually maintenance related
  6. 6

    Side repeater slightly discoloured

    8,802 notes4.4.3 (a)
    What it means, why it happens, what to check

    What it means

    An indicator repeater lens is faded or discoloured, which can reduce how clearly your signal is seen.

    Why it happens

    UV exposure and age bleach plastic lenses, especially on higher-mileage cars.

    Buyer tip

    Budget for a replacement repeater lens — usually a cheap fix compared with a failed test.

    Severity

    Usually maintenance related
  7. 7

    Headlamp aim projected beam image is obviously incorrect

    6,270 notes4.1.2 (c)
    What it means, why it happens, what to check

    What it means

    This MOT defect usually indicates incorrect headlamp alignment following adjustment, suspension movement or repair work.

    Why it happens

    Aim drifts after suspension work, bumper repairs, bulb changes or simply from road vibration over time.

    Buyer tip

    Check beam alignment during inspection and ask whether the lamps were aimed after any recent suspension or bodywork.

    Severity

    Usually maintenance related
  8. 8

    Headlamp insecure

    1,325 notes4.1.1 (c)
    What it means, why it happens, what to check

    What it means

    The headlamp unit is not held firmly in place. Vibration can move the beam and leave you with poor night visibility or dazzle for other drivers.

    Why it happens

    Mounting clips, brackets or crash-related repairs can leave the lamp unit loose.

    Buyer tip

    Inspect the lamp mounts and any crash repairs around the front end before you buy.

    Severity

    Usually maintenance related

Most common wear & tear faults

DVSA wording grouped as wear and tear for this model and age band.

  1. 1

    Exhaust emissions likely to be affected by an exhaust leak

    158 notes8.2.1.1 (b)
    What it means, why it happens, what to check

    What it means

    Emissions could not be completed cleanly, or a leak is likely to upset the reading. Common causes include exhaust leaks, misfires, DPF issues or an engine that will not idle correctly.

    Why it happens

    Leaks before the sample point, misfires, DPF problems or unstable idle prevent a valid emissions result.

    Buyer tip

    Listen for blow-by at joints, check for recent exhaust/DPF work, and avoid cars that need “easier” emissions excuses.

    Severity

    Usually wear related
  2. 2

    Exhaust emissions likely to be affected by an exhaust leak

    65 notes8.2.2.1 (b)
    What it means, why it happens, what to check

    What it means

    Emissions could not be completed cleanly, or a leak is likely to upset the reading. Common causes include exhaust leaks, misfires, DPF issues or an engine that will not idle correctly.

    Why it happens

    Leaks before the sample point, misfires, DPF problems or unstable idle prevent a valid emissions result.

    Buyer tip

    Listen for blow-by at joints, check for recent exhaust/DPF work, and avoid cars that need “easier” emissions excuses.

    Severity

    Usually wear related
  3. 3

    Rear Shock absorbers has an excessively worn bush

    42 notes5.3.2 (c)
    What it means, why it happens, what to check

    What it means

    A damper mounting bush is worn, which can cause knocks, vague handling and accelerated tyre wear.

    Why it happens

    Rubber bushes harden and tear with age, road salt and repeated suspension movement.

    Buyer tip

    Listen for clunks over speed bumps and have a mechanic check top mounts and lower bushes.

    Severity

    Usually wear related
  4. 4

    Emissions unable to be completed exhaust leak

    37 notes8.2.1.2 (d)
    What it means, why it happens, what to check

    What it means

    Emissions could not be completed cleanly, or a leak is likely to upset the reading. Common causes include exhaust leaks, misfires, DPF issues or an engine that will not idle correctly.

    Why it happens

    Leaks before the sample point, misfires, DPF problems or unstable idle prevent a valid emissions result.

    Buyer tip

    Listen for blow-by at joints, check for recent exhaust/DPF work, and avoid cars that need “easier” emissions excuses.

    Severity

    Usually wear related
  5. 5

    Brake pedal anti-slip provision worn smooth

    18 notes1.1.2 (c)
    What it means, why it happens, what to check

    What it means

    The brake pedal rubber is worn smooth, reducing grip for your foot in the wet.

    Why it happens

    The pedal rubber wears through with daily use and is often left until an MOT flags it.

    Buyer tip

    A new pedal rubber is inexpensive — treat smooth pedals as a quick owner-maintenance fix.

    Severity

    Usually wear related
  6. 6

    Rear Service brake excessively binding wheel bearing not tested

    12 notes1.2.1 (f)
    What it means, why it happens, what to check

    What it means

    Service brake performance could not be fully verified, or a brake is binding/fluctuating. That often points to worn discs, seized calipers or hub issues.

    Why it happens

    Seized caliper slides, worn discs or contaminated friction material upset brake balance.

    Buyer tip

    Insist on a road test and a proper brake inspection; unresolved binding can destroy pads and hubs.

    Severity

    Usually wear related
  7. 7

    Exhaust mounting defective Fairly worn flex and centre mounts

    11 notes6.1.2 (a)
    What it means, why it happens, what to check

    What it means

    An exhaust mount is worn or the system is insecure/leaking. That can worsen noise, fumes and later emissions failures.

    Why it happens

    Rubber hangers perish and joints loosen with heat cycles and corrosion.

    Buyer tip

    Look under the car for hanging sections, cracked rubbers and sooty leak marks at joints.

    Severity

    Usually wear related
  8. 8

    Brake performance not tested Due to worn brakes.

    11 notes1.2.1 (g)
    What it means, why it happens, what to check

    What it means

    Service brake performance could not be fully verified, or a brake is binding/fluctuating. That often points to worn discs, seized calipers or hub issues.

    Why it happens

    Seized caliper slides, worn discs or contaminated friction material upset brake balance.

    Buyer tip

    Insist on a road test and a proper brake inspection; unresolved binding can destroy pads and hubs.

    Severity

    Usually wear related

Most common systemic faults

DVSA wording grouped as systemic patterns for this model and age band.

  1. 1

    Engine MIL inoperative or indicates a malfunction

    8,078 notes8.2.1.2 (h)
    What it means, why it happens, what to check

    What it means

    The engine management warning lamp is on or not working. Stored faults can affect emissions, drivability and future MOT results.

    Why it happens

    Sensors, emissions equipment or wiring faults store codes that illuminate the MIL.

    Buyer tip

    Ask for a diagnostic printout and proof that the underlying fault — not just the lamp — was fixed.

    Severity

    Often a recurring model pattern
  2. 2

    Brake pipe excessively damaged

    3,506 notes1.1.11 (c)
    What it means, why it happens, what to check

    What it means

    A brake pipe is damaged or heavily corroded. Pipe failure can cause sudden loss of braking effort.

    Why it happens

    Road salt, stone chips and age corrode metal pipes, especially along the underbody.

    Buyer tip

    Inspect metal pipes along the underbody and near calipers; corroded pipes should be replaced before you rely on the car.

    Severity

    Often a recurring model pattern
  3. 3

    Engine MIL inoperative or indicates a malfunction

    2,265 notes8.2.2.2 (g)
    What it means, why it happens, what to check

    What it means

    The engine management warning lamp is on or not working. Stored faults can affect emissions, drivability and future MOT results.

    Why it happens

    Sensors, emissions equipment or wiring faults store codes that illuminate the MIL.

    Buyer tip

    Ask for a diagnostic printout and proof that the underlying fault — not just the lamp — was fixed.

    Severity

    Often a recurring model pattern
  4. 4

    Registration plate deteriorated but not likely to be misread cracked

    174 notes0.1 (b)
    What it means, why it happens, what to check

    What it means

    The number plate is cracked, deteriorated or hard to read. Plates must remain legible and securely fitted.

    Why it happens

    Age, stone chips, poor replacements or mounts that flex crack or fade plates.

    Buyer tip

    Budget for legal replacement plates; check fixing and any bike-rack or tow-bar obstruction.

    Severity

    Often a recurring model pattern
  5. 5

    Exhaust system insecure front bracket

    70 notes6.1.2 (a)
    What it means, why it happens, what to check

    What it means

    An exhaust mount is worn or the system is insecure/leaking. That can worsen noise, fumes and later emissions failures.

    Why it happens

    Rubber hangers perish and joints loosen with heat cycles and corrosion.

    Buyer tip

    Look under the car for hanging sections, cracked rubbers and sooty leak marks at joints.

    Severity

    Often a recurring model pattern
  6. 6

    Steering locking device missing

    60 notes2.1.3 (d)
    What it means, why it happens, what to check

    What it means

    The steering lock is missing or ineffective. That affects theft protection and can be an MOT failure item.

    Why it happens

    Column locks wear, or aftermarket work interferes with the lock mechanism.

    Buyer tip

    Confirm the steering lock engages with the key removed and investigate any aftermarket column work.

    Severity

    Often a recurring model pattern
  7. 7

    Exhaust emissions - engine idle speed too high

    60 notes8.2.1.2 (e)
    What it means, why it happens, what to check

    What it means

    Emissions could not be completed cleanly, or a leak is likely to upset the reading. Common causes include exhaust leaks, misfires, DPF issues or an engine that will not idle correctly.

    Why it happens

    Leaks before the sample point, misfires, DPF problems or unstable idle prevent a valid emissions result.

    Buyer tip

    Listen for blow-by at joints, check for recent exhaust/DPF work, and avoid cars that need “easier” emissions excuses.

    Severity

    Often a recurring model pattern
  8. 8

Ford Focus research summary

Based on over 1.4 million official UK MOT tests, Ford Focus models registered between 2016 and 2021 achieve a strong 86.6% MOT pass rate.

The overwhelming majority of recorded MOT defects relate to routine owner maintenance, with tyres, lighting and washer systems accounting for most common faults seen on used examples in this age band.

Recurring systemic faults occur far less frequently, although engine management warning lamp (MIL) defects appear consistently across the dataset.

Overall, the data suggests that this generation of Ford Focus is more likely to fail MOT due to maintenance items than widespread design faults, making service history and routine upkeep particularly important when buying used. Shoppers comparing a used Ford Focus should treat this research summary as model-level context before inspecting any individual car.

What this report cannot tell you

This report describes model-level MOT trends, not the condition of any individual vehicle.

Two identical Ford Focus models can have very different maintenance histories.

Use it to understand common patterns before inspecting a specific car — then check that car’s own MOT history.

How we classify MOT faults

We group recorded DVSA defect wording into four research categories to help identify whether issues are more likely to reflect routine maintenance, expected wear, recurring model patterns or miscellaneous inspection outcomes.

Owner maintenance
Defects often linked to day-to-day upkeep — tyres, lamps, washers and other items a careful owner can usually prevent or fix promptly.
Wear & tear
Age- and mileage-related deterioration that accumulates with normal use, even when a car has been looked after.
Systemic
Recurring wording and patterns across the model fleet that may point to design, component or known-model tendencies rather than one careless owner.
Other
Inspection outcomes that do not sit cleanly in the three groups above, including mixed or less classifiable defect notes.

Buying a used Ford Focus: practical MOT checks

  • 1Ask for a full service history and check tyre age and tread before the test drive.
  • 2Budget for lamp aim, washers and wear items — they dominate owner-maintenance MOT notes on this model.
  • 3Compare the Focus against a peer hatchback in the same age band, not against a single registration check alone.
  • 4Treat engine management light (MIL) advisories seriously; they appear often in systemic MOT wording for this era.

Frequently asked questions

What is the Ford Focus MOT pass rate at 5–10 years?

In the 2016–2021 registration band used for this report, the Ford Focus shows an 86.6% MOT pass rate across more than 1.4 million recorded DVSA tests in our serving dataset.

What are the most common Ford Focus MOT issues?

Owner-maintenance items lead the volume — especially tyres worn close to the legal limit, headlamp aim, and washer faults. Systemic wording frequently includes engine MIL warnings and selected brake-pipe deterioration notes.

Is this the same as checking one registration on GOV.UK?

No. GOV.UK shows one vehicle. This page aggregates MOT outcomes for the Focus model in a fixed UK registration age band so you can research the model before you shortlist cars.
