Used buying checklist
Jaguar Xjs reliability, common problems and used buying checks
A used Jaguar Xjs looks better than average for reliability in UK MOT data: 16.8% of 3,757 tests failed, compared with 18.7% across all indexed models. A good example should have a clean MOT history for corrosion and structure, emissions, engine, and exhaust, and lights and electrical.
It can be, if the exact car has a clean history for corrosion and structure, emissions, engine, and exhaust, and lights and electrical.
Start with corrosion and structure, emissions, engine, and exhaust, and lights and electrical, then compare the car's mileage and recall record below.
Sources used: DVSA MOT tests (Apr 2026); vehicle recalls (Apr 2026); MOT fault wording (May 2025). MOT data does not capture every reliability issue, especially intermittent engine, gearbox or infotainment faults that do not appear during the test.

Corrosion and structure is the clearest area to check
Corrosion and structure is the clearest named problem area in this model's MOT history (37.1 MOT notes per 100 tests). Example MOT phrases from this area include excessively corroded, corroded so that its cross sectional area is reduced and seriously weakened, and prescribed area excessively corroded significantly reducing structural strength.
Example MOT phrases to search in the car's history:
- excessively corroded
- corroded so that its cross sectional area is reduced and seriously weakened
- prescribed area excessively corroded significantly reducing structural strength
- corroded and seriously weakened
- leaking excessively from engine
- Lambda reading after 2nd fast idle outside specified limits
- emissions - engine idle speed too high
- Fuel Pipe/s corroded
- has a product on the light source so that the light output is severely reduced
- inoperative in the case of multiple lamps or light sources

Should you buy a used Jaguar Xjs?
83.2% of the MOT tests we analysed for this model passed. The model's recorded failure rate is 16.8%, -1.9 percentage points compared with the average across all models. This is a buying brief for the exact car in front of you: clean repeat history matters more than badge reputation.
- Repeat unresolved MOT notes for corrosion and structure, emissions, engine, and exhaust, and lights and electrical
- corrosion and structure appearing across more than one MOT
- Any dangerous MOT failure on the exact car, especially if the same area appears again later
- No paperwork showing applicable recall work has been completed
- A seller who cannot explain MOT wording such as "excessively corroded"
It can be, if the exact car has a clean history for corrosion and structure, emissions, engine, and exhaust, and lights and electrical.
Start with corrosion and structure, emissions, engine, and exhaust, and lights and electrical, then compare the car's mileage and recall record below.
Corrosion and structure is the clearest named problem area in the MOT history (37.1 MOT notes per 100 tests). These counts are issue notes, not failure rates, because a single MOT can list several faults.
Past 100k miles on the Jaguar Xjs, MOT records most often point to corrosion and structure, emissions, engine, and exhaust, and lights and electrical.
The MOT failure rate rises from 0.0% at 6-10 years to 16.8% at 15+ years. Compare the car with the nearest age range before treating a fault as normal wear or a warning sign. The average MOT failure rate across all models in the same dataset is 18.7%.
Start with corrosion and structure, emissions, engine, and exhaust, lights and electrical, and suspension and steering. The checklist on this page explains why each area is being recommended, what to inspect, and what to ask the seller.
1 relevant recall notice appear for this model. Treat them as safety checks to verify for the exact car, not as normal MOT wear.
