MOT Failure Check UK

A car's MOT failure history is a window into how it has been maintained and what risks it has been driven with. Free DVSA records tell the full story. Here is how to read them like an expert before handing over any money.

Quick answer

Reading MOT Failure History

Every MOT failure is recorded in the DVSA database — free to access. Before buying, check: how many failures there are and on what items, whether the same item failed repeatedly, whether failures were on safety-critical systems (brakes, tyres, structure), and whether subsequent tests show genuine repair. A recent clean pass after a patchy failure history does not wipe the slate.

The tiers

The Three Defect Categories: What Each Means

Since May 2018, all UK MOT defects are classified into three tiers. Understanding these tiers lets you immediately assess the severity of anything in a car's failure history.

Dangerous Defect

Immediate risk to road safety. The car cannot be driven away from the test centre — not even to a repair garage. Requires transport. Police can issue penalties for driving a vehicle with a known dangerous defect. Examples: severely worn tyre, completely failed brakes.

Major Defect

Vehicle fails the MOT. Cannot legally drive on public roads. Does not mean immediately dangerous, but safety-critical enough to fail the test. Examples: one headlight out, brake imbalance, emissions over limit, cracked windscreen in driver's field.

Minor Defect (Advisory)

Vehicle passes the MOT. Tester has noted wear or deterioration that needs attention. No legal bar to driving. However items like worn brake pads or cracked tyres should be treated as urgent — they will likely fail next year.

Cost guide

Most Common MOT Failures & Typical Repair Costs

Failure item	Category	Typical repair cost	Severity
Tyre below 1.6mm tread	Major/Dangerous	£80–£140 per tyre	High
Brake imbalance	Major	£100–£350 per axle	High
Failed bulb (headlight/brake)	Major	£10–£50	Low
Emissions over limit	Major	£50–£250	Medium
Cracked windscreen (zone A)	Major/Dangerous	£200–£500	High
Structural corrosion	Major/Dangerous	£300–£3,000+	Very High
Steering play excessive	Major	£200–£600	High
Failed shock absorber	Major	£150–£350	Medium–High
Seatbelt not functioning	Major/Dangerous	£50–£200	High
Exhaust blowing badly	Major	£100–£400	Medium
Horn not working	Major	£30–£80	Low
Number plate non-compliant	Minor	£10–£25	Low

Patterns

How to Read Failure Patterns in MOT History

Single failures on easy-to-fix items (bulbs, wipers, number plates) are common and not a concern. Look for these patterns instead:

Same item failing year after year

Indicates the seller repairs the minimum required to pass the MOT and nothing more. Brakes or tyres failing repeatedly suggests the car is being run into the ground.

Structural corrosion failures

Structural rust is one of the most expensive repairs. A car with corrosion failures in its recent history should receive an independent inspection by a specialist — not just a trust in a fresh MOT pass.

Emissions failures followed by a pass

Could indicate a cheap fix (clearing fault codes before a retest) or genuine repair. Ask to see the repair invoice. An emissions failure on a diesel suggests DPF, EGR, or fuel system issues.

Fail at one centre, pass at another the same day

Rare but it happens. If a vehicle fails at one test centre and passes at a different centre on the same day or within a day or two, question whether the 'repairs' were genuine.

Passes without any advisories on old high-mileage car

Suspicious. A 150,000-mile car with zero advisories across multiple tests either has an immaculate service history or the MOT records are incomplete. Verify via DVSA directly.

Consistent annual test with minor failures only

A positive pattern. Minor failures like bulbs and wipers on every car are entirely normal. The owner is testing annually and fixing what needs fixing — this is a well-maintained vehicle.

The myth

The “Fresh MOT” Myth

Private sellers and some dealers list cars as "just passed MOT" as a selling point. This is partly true — a recent MOT pass does mean the car met minimum legal safety standards on the day of test. But it tells you nothing about:

Engine mechanical condition — oil consumption, head gasket, gearbox wear

How many items were borderline at the test — on the edge of advisory or pass

Whether advisories from previous tests were actually repaired or simply not mentioned by the tester

The overall maintenance history and service record

Whether the car was taken to multiple test centres to find a 'friendly' pass

Upcoming repairs — a fresh MOT pass can expire in 12 months, but mechanical failures happen immediately

Questions & answers

Frequently Asked Questions

How do I check a car's MOT failure history?

Use the free DVSA MOT history service, accessible via MotR's MOT History Checker. Every test result — pass, fail, or PRS — is recorded, along with the specific reason for failure. Enter the registration number to view the complete record including every defect recorded at each test.

Does a car with lots of MOT failures mean it's a bad buy?

Not necessarily. What matters is whether the failures were on the same item repeatedly (indicating systemic neglect), whether they were repaired (subsequent pass confirms repair), and the severity of the failure categories. Occasional tyre, wiper, or bulb failures are minor. Repeated brake, structural corrosion, or emissions failures are more serious.

What is a dangerous MOT defect?

A dangerous defect means the vehicle poses an immediate risk to road safety or the environment. Examples include: severely worn tyres below 1.6mm tread across the full width, failed brakes causing major imbalance, a cracked windscreen in the driver's critical zone, or seriously corroded structural components. A dangerous defect means the car cannot legally be driven away.

What is a major MOT defect?

A major defect means the vehicle fails the MOT and cannot legally be driven on public roads until repaired. It does not necessarily mean the vehicle is immediately dangerous, but it significantly affects safety or emissions. Common major defects include: one headlight out, a brake imbalance below the pass threshold, or emissions above the legal limit.

Can a car fail an MOT multiple times in a row?

Yes, and if the same item fails repeatedly across multiple tests, it is a strong signal that the seller is running the car to the point of failure and only doing the minimum to scrape a pass. Repeated braking, tyre, or structural failures are a very serious buyer warning.

Should I buy a car that recently passed after multiple failures?

Proceed with caution. A fresh pass after a failure history means the seller did the minimum to get the car through. Ask to see repair receipts for work done. If the car had structural corrosion failures, pay for an independent inspection from a specialist. A fresh MOT pass does not mean the car is in good condition — it means it meets minimum legal standards on the test day.

What are the most expensive MOT failures?

Structural corrosion repairs can cost £500–£3,000+ depending on severity and vehicle type. Catalytic converter failure (emissions): £200–£800. Major suspension failure: £300–£700. Failed brake caliper: £150–£300 per corner. Steering rack: £300–£700. Always get quotes for any failure items before agreeing a purchase price.
