Land Rover Defender MOT Failures
An analysis of 1,443,991 real DVSA MOT tests on the Land Rover Defender — what fails, how often, and how that compares to every other car on UK roads. Generations covered: Series (1948–1985), Ninety (1983–1990), Classic (1990–1998), Td5 (1998–2007), Puma (2007–2016), L663 (2020–2024).
Where the Land Rover Defender fails its MOT
The single biggest MOT failure point on the Land Rover Defender is steering rack wear — this model is 1220 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 1,443,991 MOT tests, 0.4% of all Land Rover Defender tests recorded this as a failure.
Steering faults include worn track rod ends, power steering leaks, and rack wear. These are safety-critical — any play in the steering should be investigated immediately.
Other notable weak points include emissions failure (867x the fleet average), axle or kingpin wear (472x the fleet average), track rod ends worn (415x the fleet average), and towbar fault (674x the fleet average). These ratios compare the Land Rover Defender'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 5 categories: Steering, Exhaust & Emissions, Suspension, Bodywork, Brakes. If you're inspecting a Land Rover Defender 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 Land Rover Defender'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 Land Rover Defender specifically, the DVSA data shows the most common failures at this mileage are towbar fault (674x the average) and axle or kingpin wear (472x). track rod ends worn (415x) and body panel damage (341x) 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 Land Rover Defender specifically, the DVSA data shows the most common failures at this mileage are emissions failure (867x the average) and steering rack wear (355x). towbar fault (297x) and free play in the steering, measured at the rim ... (271x) 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 Land Rover Defender specifically, the DVSA data shows the most common failures at this mileage are emissions failure (258x the average) and steering rack wear (171x). track rod ends worn (142x) and abs fault (121x) also appear frequently.
The shift from towbar fault at lower mileages to emissions failure 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 Land Rover Defender specialists and owners flag most frequently, drawn from manufacturer technical bulletins, workshop data, and verified owner reports.
Oil pump drive failure (Td5) Dangerous
The Td5 engine drives its oil pump via a steel shaft that passes through the crankcase and connects to the oil pump housing. Affects Td5; typical independent garage repair cost is £1,000–£2,000.
Chassis and outrigger corrosion Dangerous
Defender chassis rails and outriggers (cross-members that support body mounting points) are constructed from mild steel with limited corrosion protection. Affects Series, Ninety/One-Ten, Classic, Td5, Puma; typical independent garage repair cost is £1,500–£4,000.
Injector failure (Puma) Major
The Ford DuraTorq engines used in Puma-generation Defenders suffer from common rail injector seal failure and carbon build-up affecting the 2.2 TDCi and 2.4 TDCi variants. Affects Puma; typical independent garage repair cost is £400–£800.
Steering box oil leaks Major
All traditional Defenders use a recirculating ball steering box that develops seal leaks as mileage increases. Affects Series, Ninety/One-Ten, Classic, Td5, Puma; typical independent garage repair cost is £400–£800.

What to check before buying a Land Rover Defender
Based on the MOT failure data and known issues above, here's what to prioritise when inspecting a Land Rover Defender:
Steering — check for steering rack wear, track rod ends worn. Exhaust & Emissions — check for emissions failure. Suspension — check for axle or kingpin wear.
Beyond the MOT items, ask specifically about oil pump drive failure and chassis and outrigger corrosion. These won't show up on a standard MOT but can be expensive to fix — repairs start from £1,000. 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.
