Top issues to watch for

The most serious Jaguar S Type problems ranked by severity. We track 5 known issues — here are the ones you need to know about first.

Dangerous
Vehicle structure corrosion affecting structural rigidity (X200)
X2001999–200820k–150k miles
The S-Type suffers from severe structural corrosion that compromises the vehicle's structural integrity. MOT data shows this model fails structural rigidity tests at 1051.2 times the national fleet average, with 671 recorded failures across all variants. The corrosion typically affects the subframe mounting points, sills, and floor pan areas where water becomes trapped. This is a safety-critical defect that can affect crash protection and handling stability.
What happens if ignoredSevere structural corrosion compromises crash safety and can cause subframe detachment while driving. Repair typically requires extensive welding work costing £2,000-£5,000 or may render the vehicle beyond economical repair. The vehicle should not be driven if structural integrity is compromised.

Major
Suspension component wear and corrosion (X200)
X2001999–200840k–150k miles
The S-Type suffers from premature suspension component wear and corrosion at rates significantly above the national average. MOT data shows excessive wear failures at 2740.0 times fleet average and corrosion damage at 2740.0 times average, with over 22,000 combined failures recorded. The aluminium suspension components corrode rapidly, particularly the front lower wishbones and rear suspension links.
What happens if ignoredWorn or corroded suspension components affect handling, steering precision, and tyre wear. Failed components can cause dangerous handling characteristics. Front wishbone replacement typically costs £300-£600 per side including alignment. Multiple component failure can easily exceed £1,500.

Major
Electronic parking brake failure (X200 diesel)
X2002720cc1999–200860k–150k miles
The 2.7 TDV6 S-Type models fitted with electronic parking brake systems suffer from high failure rates. 334.4 times average. The electronic actuator motors and control modules are prone to failure, leaving the vehicle without a functioning parking brake.
What happens if ignoredElectronic parking brake failure means the vehicle cannot be legally parked on a slope and may not pass MOT. Repair typically requires replacement of the electronic actuator motors or control module at costs of £600-£1,200. The vehicle remains driveable but parking options are severely limited.

Minor
Suspension joint dust cover failure (X200)
X2001999–200820k–150k miles
The S-Type has exceptionally high rates of suspension joint dust cover deterioration and loss. MOT data shows failure rates up to 1,2740.0 times the national fleet average, with 65 recorded failures. The rubber boots protecting ball joints and track rod ends perish rapidly, allowing dirt and water ingress that accelerates joint wear. This affects all variants but is most severe on the 2.5-litre petrol models.
What happens if ignoredFailed dust covers allow water and dirt into suspension joints, accelerating wear and requiring joint replacement. Individual joint replacement costs £100-£300 per corner. If left unchecked, joint failure can affect steering precision and safety.
