Common Problems with the
2007 Jaguar XK8 / XKR (X100)
The 2007 Jaguar XK8 / XKR (X100) has an excellent reliability record with no widely reported common faults for this model year period.
Buying Tips for 2007 Jaguar XK8 / XKR (X100)
- Demand documented proof that early 4.0-litre AJ26/AJ27 engines have had their fragile plastic secondary timing chain tensioners upgraded to third-generation metal-bodied units.
- Inspect the structural sills and floorpans thoroughly; corrosion hidden behind the plastic sill kick-plates and around the rear subframe mounts is the leading cause of MOT failure.
- On convertible models, check the hydraulic hood mechanism for slow operation, green fluid leaks beneath the rear seat, or hydraulic ram hose degradation.
- Verify automatic transmission servicing; the five-speed ZF 5HP24 (and Mercedes 722.6 on early XKR) requires fresh fluid and filter changes every 50,000 miles despite original sealed-for-life claims.
- Test the condition of the front suspension wishbone bushes and CATS adaptive dampers; heavy V8 front-end weight rapidly wears lower ball joints and causes uneven front tyre wear.
