Vauxhall Vectra MOT Failures
An analysis of 605,165 real DVSA MOT tests on the Vauxhall Vectra — what fails, how often, and how that compares to every other car on UK roads. Generations covered: B (1995–2002), C (2002–2009).
Where the Vauxhall Vectra fails its MOT
The single biggest MOT failure point on the Vauxhall Vectra is emissions failure — this model is 102 times more likely to fail on this item than the average car on UK roads. That makes it an extreme outlier for anyone buying or owning this model. Across 605,165 MOT tests, 1.99% of all Vauxhall Vectra tests recorded this as a failure.
Exhaust and emissions failures often point to catalytic converter degradation, lambda sensor faults, or — in diesel models — DPF problems. These can be expensive to fix and will cause an immediate MOT failure.
Other notable weak points include suspension component damaged or corroded (53x the fleet average), brake pipes corroded (94x the fleet average), brake hoses perished or damaged (30x the fleet average), and abs fault (318x the fleet average). These ratios compare the Vauxhall Vectra'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 6 categories: Exhaust & Emissions, Suspension, Brakes, Bodywork, Seatbelts & Airbags and others. If you're inspecting a Vauxhall Vectra 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 Vauxhall Vectra'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 Vauxhall Vectra specifically, the DVSA data shows the most common failures at this mileage are mandatory tell-tale for main beam headlamp or r... (347x the average) and abs fault (318x). speedometer not illuminated (267x) and mandatory tell-tale for direction indicators mi... (234x) 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 Vauxhall Vectra specifically, the DVSA data shows the most common failures at this mileage are exhaust system damage (39x the average) and suspension component damaged or corroded (38x). seat mounting fault (32x) and emissions failure (22x) 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 Vauxhall Vectra specifically, the DVSA data shows the most common failures at this mileage are exhaust system damage (20x the average) and suspension pin, bush or joint worn (18x). suspension component damaged or corroded (17x) and coil springs broken (16x) also appear frequently.
The shift from mandatory tell-tale for main beam headlamp or r... at lower mileages to exhaust system damage 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 Vauxhall Vectra specialists and owners flag most frequently, drawn from manufacturer technical bulletins, workshop data, and verified owner reports.
Brake pipe corrosion and failure Dangerous
The Vectra has extremely high rates of brake pipe corrosion leading to hydraulic system failure. Affects B, C; typical independent garage repair cost is £200–£800.
Suspension component corrosion and damage Major
MOT data shows Vectras fail suspension component inspections at 64.9 times the fleet average, with over 31,000 recorded failures. Affects B, C; typical independent garage repair cost is £300–£800.
Shock absorber failure Major
Vectras show shock absorber failure at 41.3 times the national average according to MOT data, with over 7,300 recorded failures. Affects B, C; typical independent garage repair cost is £250–£600.
Suspension joint dust cover deterioration
MOT data shows extremely high rates of suspension joint dust cover failure - up to 34.5 times the fleet average. Affects B, C; typical independent garage repair cost is £80–£200.

What to check before buying a Vauxhall Vectra
Based on the MOT failure data and known issues above, here's what to prioritise when inspecting a Vauxhall Vectra:
Exhaust & Emissions — check for emissions failure. Suspension — check for suspension component damaged or corroded. Brakes — check for brake pipes corroded, brake hoses perished or damaged, abs fault.
Beyond the MOT items, ask specifically about brake pipe corrosion and failure and suspension component corrosion and damage. These won't show up on a standard MOT but can be expensive to fix — repairs start from £200. 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.
