Jaguar Eagle MOT Failures

An analysis of 1,860 real DVSA MOT tests on the Jaguar Eagle — what fails, how often, and how that compares to every other car on UK roads.

Where the Jaguar Eagle fails its MOT

The single biggest MOT failure point on the Jaguar Eagle is rear registration plate lamp or light source mi... — this model is 8.1 times more likely to fail on this item than the average car on UK roads. That makes it worth watching for anyone buying or owning this model. Across 1,860 MOT tests, 3.96% of all Jaguar Eagle tests recorded this as a failure.

Lighting faults are usually straightforward to fix (bulbs, connectors, earth points) but can indicate deeper wiring issues on older cars. Check all lights including fog lamps, number plate lights, and dashboard warning lights.

Other notable weak points include tyre tread depth not in accordance with the req... (6.0x the fleet average) and tyre cords visible or damaged (5.5x the fleet average). These ratios compare the Jaguar Eagle'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 2 categories: Lights & Electrics, Tyres. If you're inspecting a Jaguar Eagle 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 Jaguar Eagle'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 Jaguar Eagle specifically, the DVSA data shows the most common failures at this mileage are rear registration plate lamp or light source mi... (8.1x the average) and tyre tread depth not in accordance with the req... (6.0x).

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.

The standout failure at this mileage is tyre cords visible or damaged at 5.5x the fleet average.

The shift from rear registration plate lamp or light source mi... at lower mileages to tyre cords visible or damaged 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.

What to check before buying a Jaguar Eagle

Based on the MOT failure data and known issues above, here's what to prioritise when inspecting a Jaguar Eagle:

Lights & Electrics — check for rear registration plate lamp or light source mi.... Tyres — check for tyre tread depth not in accordance with the req..., tyre cords visible or damaged.

Always check the car's full MOT history for patterns — recurring advisories often become failures within 12 months. Enter any reg into our free car check to see the complete picture.
