Top issues to watch for
The most serious Jaguar Xkr problems ranked by severity. We track 5 known issues — here are the ones you need to know about first.
Dangerous
Subframe mounting area corrosion (X100/X150)
The rear subframe mounting points on both X100 and X150 generation XKRs are susceptible to corrosion that compromises structural integrity. This is classified as a prescribed area under MOT regulations where any structural weakness constitutes an immediate dangerous defect. The problem affects the mounting points where the rear subframe attaches to the main body structure.
What happens if ignoredSubframe detachment represents a catastrophic structural failure that can cause complete loss of vehicle control, particularly under braking or cornering loads. Repair requires cutting out corroded sections and welding in new metal, typically costing £2,000-£4,000. Cars with advanced corrosion may be beyond economical repair. The vehicle is unsafe to drive if structural integrity is compromised.

Major
Suspension joint dust cover deterioration (X100/X150)
The XKR suffers from premature deterioration of suspension joint dust covers across all variants, with MOT data showing failure rates up to 507 times the national fleet average. These rubber and plastic boots protect ball joints, control arm bushes, and anti-roll bar connections from water and contamination. When compromised, water and road debris enter the joints causing accelerated wear, play development, and eventual component failure. The problem is particularly severe on the 5.0L variants between 20,000-40,000 miles.
What happens if ignoredFailed dust covers allow water and debris to contaminate suspension joints, leading to premature wear and play development. This progresses to component failure requiring replacement of ball joints, bushes, or complete suspension arms. Individual joint replacement costs £150-£400 per corner, but multiple joints often require replacement together. Continued driving with worn joints affects handling precision and may cause MOT failure.

Major
Transmission belt or chain excessive wear (X100)
The automatic transmission on X100 generation XKRs experiences premature wear of internal drive chains and belts, with MOT failure rates 214.6 times higher than the national average on 4.0L variants. This affects the ZF 5HP24 five-speed automatic gearbox used across the range. Internal wear typically manifests as delayed engagement, harsh shifting, or transmission slipping under load. The problem is particularly pronounced between 40,000-60,000 miles and appears to be related to inadequate transmission fluid change intervals.
What happens if ignoredTransmission failure typically requires complete rebuild or replacement costing £3,000-£6,000. Early intervention with fluid changes and additive treatments may extend life, but advanced wear is irreversible. Signs of slipping or delayed engagement indicate the transmission should not be subjected to heavy acceleration or towing loads.

Major
Wheel bearing excessive play (X100/X150)
Both generations of XKR experience premature wheel bearing wear, with MOT statistical evidence showing failure rates 31.6 times higher than the national fleet average. The problem primarily affects front wheel bearings on 4.0L variants around 20,000-40,000 miles, suggesting a design or specification issue. Unlike many modern cars with sealed hub units, the XKR uses serviceable tapered roller bearings that require proper preload adjustment during installation.
What happens if ignoredAdvanced bearing wear causes wheel wobble, increased tyre wear, and potential wheel detachment in extreme cases. Replacement typically costs £200-£400 per corner including labour. The car remains driveable with mild bearing noise but should be repaired promptly as failure progression can be rapid once play develops.
