Jaguar Xk MOT Failures
An analysis of 105,400 real DVSA MOT tests on the Jaguar Xk — what fails, how often, and how that compares to every other car on UK roads. Generations covered: X100 (1996–2006), X150 (2006–2014).
Where the Jaguar Xk fails its MOT
The single biggest MOT failure point on the Jaguar Xk is suspension ball joints worn — this model is 1093 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 105,400 MOT tests, 3.47% of all Jaguar Xk tests recorded this as a failure.
Suspension failures typically mean worn bushes, drop links, or dampers. These affect handling and tyre wear. Budget £150–£400 per corner at an independent garage for full suspension overhaul.
Other notable weak points include track rod ends worn (52x the fleet average), suspension joint dust cover missing or no longe... (179x the fleet average), abs fault (11x the fleet average), and brake hoses perished or damaged (51x the fleet average). These ratios compare the Jaguar Xk'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: Suspension, Steering, Brakes, Lights & Electrics, Wheels. If you're inspecting a Jaguar Xk 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 Xk'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 Xk specifically, the DVSA data shows the most common failures at this mileage are suspension ball joints worn (1093x the average) and front or rear fog lamp with a multiple light so... (147x). suspension joint dust cover missing or no longe... (55x) and track rod ends worn (52x) 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 Jaguar Xk specifically, the DVSA data shows the most common failures at this mileage are front or rear fog lamp with a multiple light so... (296x the average) and suspension ball joints worn (165x). track rod ends worn (32x) and headlight fault (32x) 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 Jaguar Xk specifically, the DVSA data shows the most common failures at this mileage are suspension ball joints worn (141x the average) and light unit fault (45x). track rod ends worn (13x) and power steering fault (9.1x) also appear frequently.
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 Jaguar Xk specialists and owners flag most frequently, drawn from manufacturer technical bulletins, workshop data, and verified owner reports.
Vehicle structure corrosion (X100) Dangerous
MOT data shows X100 XK models experience structural corrosion at over 6 times the national average, typically affecting cars at 80,000-120,000 miles. Affects X100; typical independent garage repair cost is £500–£2,000.
Brake hose ferrule corrosion Major
MOT statistics show XK models fail at 14 times the national average for brake hose ferrule corrosion. Affects X100, X150; typical independent garage repair cost is £200–£350.
Suspension joint dust cover deterioration
MOT data shows this model fails at extremely high rates for suspension joint dust cover deterioration - up to 501 times the national fleet average. Affects X100, X150; typical independent garage repair cost is £50–£150.
Steering rack gaiter deterioration
The X100 generation XK shows steering rack gaiter (protective boot) failure at up to 51 times the national average according to MOT data. Affects X100; typical independent garage repair cost is £80–£150.

What to check before buying a Jaguar Xk
Based on the MOT failure data and known issues above, here's what to prioritise when inspecting a Jaguar Xk:
Suspension — check for suspension ball joints worn, suspension joint dust cover missing or no longe.... Steering — check for track rod ends worn. Brakes — check for abs fault, brake hoses perished or damaged.
Beyond the MOT items, ask specifically about vehicle structure corrosion and brake hose ferrule corrosion. These won't show up on a standard MOT but can be expensive to fix — repairs start from £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.
