Mazda 626 MOT Failures
An analysis of 10,071 real DVSA MOT tests on the Mazda 626 — what fails, how often, and how that compares to every other car on UK roads. Generations covered: GE (1992–2002).
Where the Mazda 626 fails its MOT
The single biggest MOT failure point on the Mazda 626 is vehicle structure corroded to the extent that t... — this model is 39 times more likely to fail on this item than the average car on UK roads. That makes it a significant weak point for anyone buying or owning this model. Across 10,071 MOT tests, 11.48% of all Mazda 626 tests recorded this as a failure.
Bodywork failures usually mean structural corrosion — not cosmetic rust, but rot that affects the car's structural integrity. Check sills, subframes, and chassis rails carefully, especially on older examples.
Other notable weak points include brake hoses perished or damaged (42x the fleet average), abs fault (27x the fleet average), seat mounting fault (26x the fleet average), and suspension component damaged or corroded (34x the fleet average). These ratios compare the Mazda 626's failure rate on each item against the national average for all cars tested — a ratio of 10x means this model fails ten times more often than a typical car.
The failures span 4 categories: Bodywork, Brakes, Suspension, Seatbelts & Airbags. If you're inspecting a Mazda 626 before purchase, these are the areas to focus on — and if any have been flagged as advisories on a previous MOT, they're likely to become failures in the near future.
How failures change with mileage
The Mazda 626's weak points shift as the car covers more miles. Understanding these patterns helps you know what to expect — and what to budget for — at each stage of ownership.
Under 60,000 miles
At this mileage, most failures are either design-related or caused by age rather than wear. Components like bushes and drop links may not have been replaced yet, and original-fit parts can deteriorate even on low-mileage cars that spend a lot of time sitting.
For the Mazda 626 specifically, the DVSA data shows the most common failures at this mileage are brake hoses perished or damaged (42x the average) and vehicle structure corroded to the extent that t... (39x). abs fault (27x) and suspension component damaged or corroded (17x) also appear frequently.
60,000 to 100,000 miles
This is where routine wear items start to show up. Brake components, tyres, and exhaust parts have done serious work by this point. Cars that have been well serviced will show fewer of these failures — this mileage band is where good maintenance really separates the well-kept from the neglected.
For the Mazda 626 specifically, the DVSA data shows the most common failures at this mileage are seat mounting fault (26x the average) and abs fault (23x). vehicle structure corroded to the extent that t... (21x) and structural corrosion (17x) also appear frequently.
Over 100,000 miles
High-mileage cars accumulate failures across multiple systems. The key question isn't whether things will need doing — they will — but whether the car has been maintained well enough to keep on top of them. Look for a consistent service history and recent MOT passes with minimal advisories.
For the Mazda 626 specifically, the DVSA data shows the most common failures at this mileage are suspension component damaged or corroded (34x the average) and abs fault (13x). subframe bushes or mounts worn (13x) and seat mounting fault (13x) also appear frequently.
The shift from brake hoses perished or damaged at lower mileages to suspension component damaged or corroded at higher mileages is typical — early failures tend to be design or factory-related, while high-mileage failures reflect accumulated mechanical wear. A car that's been well maintained will usually dodge the worst of both.
Known issues beyond the MOT
An MOT only tests roadworthiness at a single point in time — it won't catch developing faults, intermittent problems, or issues that haven't yet reached the failure threshold. These are the issues that Mazda 626 specialists and owners flag most frequently, drawn from manufacturer technical bulletins, workshop data, and verified owner reports.
Subframe and suspension mounting point corrosion (GE) Dangerous
The steel subframe and suspension mounting areas are prone to severe corrosion on the GE generation 626. Affects GE; typical independent garage repair cost is £600–£1,200.
Brake hose deterioration (GE) Dangerous
Flexible brake hoses on the GE 626 deteriorate at an exceptionally high rate, with MOT data showing 41.7 times the national average for hose damage. Affects GE; typical independent garage repair cost is £120–£200.
Body shell structural corrosion (GE) Major
The GE 626 suffers from severe body shell corrosion that compromises structural rigidity. Affects GE; typical independent garage repair cost is £1,000–£3,000.
Suspension component corrosion (GE) Major
Suspension components on the GE 626 corrode at 17.2 times the national average rate. Affects GE; typical independent garage repair cost is £200–£600.

What to check before buying a Mazda 626
Based on the MOT failure data and known issues above, here's what to prioritise when inspecting a Mazda 626:
Bodywork — check for vehicle structure corroded to the extent that t..., structural corrosion. Brakes — check for brake hoses perished or damaged. Suspension — check for abs fault, suspension component damaged or corroded, anti-roll bar links worn, subframe bushes or mounts worn. Seatbelts & Airbags — check for seat mounting fault.
Beyond the MOT items, ask specifically about subframe and suspension mounting point corrosion and brake hose deterioration. These won't show up on a standard MOT but can be expensive to fix — repairs start from £600. A specialist pre-purchase inspection is worth the investment on this model.
Always check the car's full MOT history for patterns — recurring advisories often become failures within 12 months. And verify the service history to confirm maintenance has been kept up to schedule. Enter any reg into our free car check to see the complete picture.
