Jaguar S Type common problems
The most common reason a Jaguar S Type fails its MOT is a split joint boot, on 13.3% of its 3,426 failed tests in 2025. Against other cars of the same age, 7 faults stand out, the widest gaps being: a worn steering or suspension joint at 11.5% of failures against 1.3% expected; a split joint boot at 13.3% of failures against 2.5% expected; a lighting fault at 5.8% of failures against 2.7% expected.

What fails a Jaguar S Type MOT
Each bar is the share of failed Jaguar S Type tests with that defect. Where we can compare it with cars of the same registration years, the marker shows what an average car of those ages records (12 of the 12 items below).
Most common reasons for failure
A test can fail for more than one defect, so shares add up to more than 100%.
| Defect | Share of failed tests |
|---|---|
| Suspension arms: ball joint dust cover no longer prevents the ingress of dirt Suspension | 13.3% |
| Track rod end: ball joint dust cover excessively damaged or deteriorated so that it no longer prevents the ingress of dirt Steering | 11.5% |
| Malfunction indicator lamp: inoperative or indicates a malfunction Noise, emissions and leaks | 9.7% |
| Linkage ball joint dust cover no longer prevents the ingress of dirt Suspension | 7.9% |
| Suspension arms: pin or bush excessively worn Suspension | 7.8% |
| Headlamp aim: too low Lamps, reflectors and electrical equipment | 7.6% |
| Position lamp: not working Lamps, reflectors and electrical equipment | 7.3% |
| Wipers: does not clear the windscreen effectively Visibility | 6.7% |
| Component mounting prescribed area excessively corroded significantly reducing structural strength Suspension | 6.5% |
| Headlamp aim: projected beam image is obviously incorrect Lamps, reflectors and electrical equipment | 6.0% |
| Anti-lock braking system: warning lamp indicates an ABS fault Brakes | 5.8% |
| Brake pads: less than 1.5 mm thick Brakes | 5.7% |

Split joint boot
13.3% of failures 2.5% expected 5.3 times as often
A split rubber boot on a joint or driveshaft. The joint may still be sound, but dirt and water get in once the boot is open.
Turn the wheels to full lock and look behind them for greasy splits in the rubber concertina.
-
Worn steering or suspension joint
11.5% of failures 1.3% expected 8.8 times as often
Play in a steering or suspension joint, where a worn ball and socket lets the wheel move where it should not.
A knock at low speed over rough ground, or vague steering, is the usual warning.
-
Engine management light on
9.7% of failures 6.4% expected 1.5 times as often
The engine management light is on, or has been disconnected. Either fails the test.
A cheap code reader on the diagnostic socket will say what the car has stored before you pay for a test.
-
Split joint boot
7.9% of failures 3.7% expected 2.1 times as often
A split rubber boot on a joint or driveshaft. The joint may still be sound, but dirt and water get in once the boot is open.
Turn the wheels to full lock and look behind them for greasy splits in the rubber concertina.
-
Worn suspension bushes
7.8% of failures 4.8% expected 1.6 times as often
Worn rubber bushes in a suspension arm, letting the arm move under load.
Perished or cracked rubber at the inner ends of the lower arms, visible with the wheel turned.
-
Headlamp aim set too low
7.6% of failures 3.9% expected 1.9 times as often
The dipped beam points lower than it should, so it lights too little of the road.
Nothing to do at the roadside, but a garage resets the aim in minutes; a sagging suspension corner or a heavy boot load can throw it out.
Which parts of the car fail
Suspension is the area that most often fails a Jaguar S Type, on 45.0% of failed tests. The widest gap against cars of the same registration years is steering, on 19.8% against 8.6% expected.

What testers warn about
62.6% of Jaguar S Type tests ended with at least one advisory: a fault the tester found that did not fail the test. On Jaguar S Types, these are the items to ask about on a car you are viewing, because they are what the last tester expected to go next.
Most common advisories
Share of all tests, passes included.
| Advisory | Share of tests |
|---|---|
| Tread depth: worn close to legal limit or worn on edge Tyres | 15.4% |
| Engine oil leak, but not excessive Noise, emissions and leaks | 12.2% |
| Rigid brake pipes: corroded, covered in grease or other material Brakes | 12.2% |
| Sub-frame: corroded but not seriously weakened Suspension | 11.7% |
| Suspension arms: pin or bush worn but not resulting in excessive movement Suspension | 11.2% |
| Brake discs: worn, pitted or scored, but not seriously weakened Brakes | 10.3% |
| Tyres: slightly damaged or cracking or perishing Tyres | 9.6% |
| Brake pads: wearing thin Brakes | 7.2% |
| Coil spring: corroded Suspension | 5.8% |
| Flexible brake hoses: slight corrosion to ferrule Brakes | 3.8% |
| Registration plates: deteriorated but not likely to be misread Identification of the vehicle | 3.3% |
| Service brake performance: binding but not excessively Brakes | 3.0% |

Jaguar S Type problems: common questions
What is the most common problem with a Jaguar S Type?
Of the faults that fail an MOT, “Suspension arms: ball joint dust cover no longer prevents the ingress of dirt” is the most common: it appears on 13.3% of failed Jaguar S Type tests. Across categories, suspension is the area that most often fails one, on 45.0% of failed tests.
How often does a Jaguar S Type fail its MOT?
36.4% of Jaguar S Type tests in 2025 were not passed first time, from 9,412 tests of cars aged three and over. Allowing for the age and mileage of the cars tested, that gives it a UK Motoring Reliability Score of 50 out of 100, where 50 is as expected.
Does anything fail more often on a Jaguar S Type than on other cars?
Yes. “Track rod end: ball joint dust cover excessively damaged or deteriorated so that it no longer prevents the ingress of dirt” appears on 11.5% of its failures against 1.3% for cars of the same age, and “Suspension arms: ball joint dust cover no longer prevents the ingress of dirt” appears on 13.3% of its failures against 2.5% for cars of the same age. Where an item is missing from the national figures for a year, we use the smallest share those figures show, so the comparison never overstates the difference.
Are these the same as breakdowns or known faults?
No. These are the items a tester recorded at the MOT, which covers condition and safety: lamps, brakes, tyres, suspension, corrosion and emissions. A gearbox that is unpleasant, an infotainment screen that has died, or a car that will not start on a cold morning are not part of the test, so they are not in these figures.
Where do the figures come from?
Every normal MOT test of a Jaguar S Type aged three and over in Great Britain in 2025, from DVSA's anonymised MOT results. Retests are excluded, and the same fault on more than one wheel counts once.

Data sources and methodology
| Figures | Source | Period | Records | Updated |

- Shares for defects are of failed tests; shares for advisories are of all tests. A test can carry several defects, so shares add to more than 100%.
- The expected share is what an average car of the same registration years records, weighted by where this model’s failures fall. Where an item is outside the national figures for a year, the smallest share those figures show is used in its place, which is an upper bound, so the comparison never overstates a model’s problems. No expectation is published where less than 80% of the model’s failures can be compared.
- Great Britain only: DVSA does not run MOT testing in Northern Ireland. Cars under three years old are not tested.
- The descriptions of what each part does are general and the same on every model. Every figure comes from the MOT data.
