Suzuki Grand Vitara MOT Failures
An analysis of 177,209 real DVSA MOT tests on the Suzuki Grand Vitara — what fails, how often, and how that compares to every other car on UK roads. Generations covered: FT (1998–2005), JT (2005–2015).
Where the Suzuki Grand Vitara fails its MOT
The single biggest MOT failure point on the Suzuki Grand Vitara is towbar fault — this model is 489 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 177,209 MOT tests, 0.54% of all Suzuki Grand Vitara 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 anti-roll bar links worn (66x the fleet average), abs fault (74x the fleet average), suspension ball joints worn (231x the fleet average), and headlight fault (57x the fleet average). These ratios compare the Suzuki Grand Vitara'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, Suspension, Lights & Electrics, Seatbelts & Airbags. If you're inspecting a Suzuki Grand Vitara 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 Suzuki Grand Vitara'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 Suzuki Grand Vitara specifically, the DVSA data shows the most common failures at this mileage are suspension ball joints worn (231x the average) and structural corrosion (111x). abs fault (74x) and anti-roll bar links worn (66x) 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 Suzuki Grand Vitara specifically, the DVSA data shows the most common failures at this mileage are towbar fault (219x the average) and suspension ball joints worn (48x). anti-roll bar links worn (48x) and fuel tank, pipe or hose insecure (33x) 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 Suzuki Grand Vitara specifically, the DVSA data shows the most common failures at this mileage are towbar fault (236x the average) and body or cab insecure (38x). fixings missing or insecure (26x) and light unit fault (19x) also appear frequently.
The shift from suspension ball joints worn at lower mileages to towbar fault 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 Suzuki Grand Vitara specialists and owners flag most frequently, drawn from manufacturer technical bulletins, workshop data, and verified owner reports.
Subframe mounting point corrosion Dangerous
The chassis mounting points where the front and rear subframes attach suffer from severe corrosion that can compromise structural integrity. Affects FT, JT; typical independent garage repair cost is £1,500–£2,500.
General body structure corrosion Major
The vehicle structure suffers from widespread corrosion that can reduce rigidity to dangerous levels. Affects FT, JT; typical independent garage repair cost is £800–£2,000.
Suspension bush and joint wear Major
Suspension pins, bushes, and joints wear at an exceptionally high rate on this model. Affects FT, JT; typical independent garage repair cost is £400–£800.
Suspension component corrosion Major
Suspension components suffer from excessive corrosion damage that can compromise their structural integrity. Affects FT, JT; typical independent garage repair cost is £500–£900.

What to check before buying a Suzuki Grand Vitara
Based on the MOT failure data and known issues above, here's what to prioritise when inspecting a Suzuki Grand Vitara:
Bodywork — check for towbar fault, abs fault. Suspension — check for anti-roll bar links worn, suspension ball joints worn, suspension component damaged or corroded.
Beyond the MOT items, ask specifically about subframe mounting point corrosion and general body structure corrosion. These won't show up on a standard MOT but can be expensive to fix — repairs start from £1,500. 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.

Suzuki Grand Vitara MOT FAQs
What are the most common MOT failures on a Suzuki Grand Vitara?
Based on 177,209 DVSA MOT tests, the most common failure is towbar fault — at 489x the national fleet average. Other frequent failures include anti-roll bar links worn and abs fault.
Is the Suzuki Grand Vitara reliable based on MOT data?
The Suzuki Grand Vitara has 23 MOT failure categories above the fleet average. Specialists also flag subframe mounting point corrosion as a concern. A pre-purchase inspection and service history check are recommended.
What MOT failures should I expect at high mileage?
Above 100,000 miles, the Suzuki Grand Vitara most commonly fails on towbar fault and body or cab insecure. Under 60,000 miles, the main issues are suspension ball joints worn and structural corrosion.
