Failure Pattern from DVSA Data

MOT Failure History Check — How Often Has It Failed?

Enter a registration to see a car's MOT pass rate and whether the same faults keep recurring — built from every official DVSA test since 2005. A one-off fail on a bulb is nothing; a brake or corrosion fault that comes back year after year is the pattern worth catching before you buy.

Why MOT failure history matters when you're buying

Every car over three years old in England, Scotland and Wales needs an annual MOT, and every result — pass or fail, with the exact reasons — is recorded by the DVSA and kept permanently. That record is one of the few genuinely objective windows into how a used car has actually been looked after, captured independently of whatever the seller tells you.

A single MOT failure means almost nothing on its own. The most common failure items in the UK are lighting and signalling, tyres, brakes, and the suspension — and the vast majority are cheap, one-off fixes that were sorted on a same-day retest. A car that has never failed an MOT is rarer than you think, and treating any failure as a red flag would rule out most sound used cars.

The signal you actually want is the pattern. Three things turn a routine failure record into a real warning:

  • Recurring failures on the same component. Brakes or suspension that fail across several separate tests can mean the car is being patched to scrape through each MOT rather than properly repaired — a sign of deferred maintenance and a future bill heading your way.
  • Escalating advisories. An advisory is a watch-this note, not a failure. But when a corrosion or brake advisory shows up one year and becomes a major failure the next, that escalation suggests the issue was flagged and ignored. Corrosion is the one to watch: it is cheap to note and expensive to fix once it reaches a structural area.
  • A low overall pass rate. A car that fails its first attempt more often than it passes is, at minimum, worth a careful read of the failure detail and a question to the seller about the work that was done.

How to read the failure-history verdict

We turn the raw DVSA record into three plain-English signals. Here is exactly what each one means and how to act on it.

Pass rate

What share of MOT attempts this car passed first time. Context, not a verdict — read it alongside the failure detail.

Recurring failures

Components that caused a major failure in two or more separate tests. The strongest single tell of deferred maintenance.

Escalating advisories

A fault first noted as an advisory that later became a failure — classic for corrosion that was flagged and left.

What a clean failure history does NOT tell you

A clean record is reassuring, but it is not a clean bill of health. The MOT does not inspect the gearbox, clutch, engine internals or service history, and a car can pass its MOT the week before a major fault develops. “No recurring failures” is never the same as “a sound car.” Always cross-check the mileage history, confirm the service record, and get an independent pre-purchase inspection for anything expensive.

MOT failure history FAQ

What is an MOT failure history check?
An MOT failure history check reviews every MOT test a vehicle has taken since 2005 and looks at what it failed on, how often, and whether the same faults keep recurring. It is built from the official DVSA MOT record, which lists the result (pass or fail), the failure reasons, and the advisory notices for each test. MOT Checkup reads that record and summarises the pass rate, any component that failed in more than one test, and any advisory that later escalated into a failure.
Should I avoid a car that has failed its MOT before?
Not automatically. Almost every older car has failed an MOT at some point — often on a worn wiper blade, a blown bulb, or a tyre, all of which are cheap, one-off fixes. What matters is the pattern. A car that failed once and was retested the same day is very different from one that has failed on the same brakes or suspension component across several years, or where a corrosion advisory has steadily worsened into a structural failure. The pattern is the signal, not a single failure.
What does a recurring MOT failure tell you?
A component that causes a failure in more than one separate test can indicate deferred or repeated cheap-fix maintenance rather than a proper repair — for example, brakes that are patched to pass and then fail again, or suspension that is replaced on one corner but not addressed properly. It does not prove the car is unsafe now, but it is exactly the kind of thing worth asking the seller about and confirming with an independent inspection.
What is an escalating advisory?
An escalating advisory is a fault first noted as an advisory (a watch-this-area note) at one MOT that later becomes a major failure at a subsequent MOT. Corrosion is the classic example: it is flagged as an advisory for a year or two, then fails the car once it spreads to a structural area. An escalation pattern can indicate the issue was noted but never properly fixed, which is a genuine pre-purchase concern.
Is the MOT failure history check free?
Yes. The MOT failure history, pass rate, failure reasons and advisory notices all come from the free DVSA MOT record, and MOT Checkup surfaces them at no cost with no sign-up. Licensed provenance data such as outstanding finance, write-off category and stolen markers are separate paid databases we do not bundle into this free check — for those, use an HPI-style provider.
Does a clean MOT failure history mean the car is mechanically sound?
No. The MOT is a roadworthiness test at a point in time — it does not inspect the gearbox, clutch, engine internals, or service history, and a car can pass an MOT the week before a major fault develops. A clean failure history is reassuring but is never a clean bill of mechanical health. Always combine it with a service-history check, a mileage check, and ideally an independent pre-purchase inspection.
How is this different from a normal MOT history check?
A standard MOT history check lists every test result and advisory. This failure-history check adds a layer of interpretation on top of that data: it calculates the pass rate, identifies which components failed in more than one test, and flags advisories that later escalated to failures — turning a long list of test records into a clear pattern you can act on. The underlying data is the same free DVSA record.
