Aluminium V8 grand tourer for pennies on the pound
The Jaguar XK is the naturally aspirated grand tourer sibling to the XKR, offering V8 elegance without the supercharger's running costs. Spanning two generations — the X100 (1996-2006) and the aluminium X150 (2006-2014) — it targets buyers who want classic British GT styling and relaxed cruising rather than outright speed. It competes with the Mercedes SL, BMW 6 Series, and Maserati GranTurismo on the used market.
We track 5 known issues across the Jaguar XK range, including 1 rated as safety-critical. Knowing which variants and configurations to approach with caution can save you from expensive surprises after purchase.

X100 (1996–2006) — Engine options included the 4.2 V8. Our database flags 5 known issues on this generation, 1 of which are rated as safety-critical. The most significant concern is Vehicle structure corrosion (£500–£2,000 to address).
X150 (2006–2014) — Engine options included the 4.2 V8, 5.0 V8. We track 3 known issues on this generation, with 1 classified as significant. The most significant concern is Brake hose ferrule corrosion (£200–£350 to address).
MOT data shows X100 XK models experience structural corrosion at over 6 times the national average, typically affecting cars at 80,000-120,000 miles. This involves corrosion severe enough to compromise the structural integrity of the vehicle. On the X100 XK, this most commonly affects the rear subframe mounting points and sill sections. The aluminium bodywork is generally corrosion-resistant, but steel subframe components and mounting points are vulnerable.
Structural corrosion that affects the rigidity of the vehicle assembly is classified as dangerous and the car should not be driven until repaired. Subframe mounting point failure can cause complete loss of rear suspension control. Repair costs vary enormously depending on the extent of damage but can exceed the value of the car if extensive welding or subframe replacement is required.
Inspect the wheel arches, sills, jacking points and door bottoms carefully. Press gently on sills to check for soft spots. Look underneath for corrosion on structural components. Check the MOT history for corrosion-related advisories or failures.
MOT statistics show XK models fail at 14 times the national average for brake hose ferrule corrosion. The metal crimped ends (ferrules) of flexible brake hoses corrode excessively on these cars, affecting both generations but particularly the X100 4.2L models. Corroded ferrules can lead to brake hose failure and complete loss of braking on the affected circuit. This issue appears across all mileage ranges including very low mileage cars.
Severely corroded ferrules can fail completely, causing immediate brake fluid loss and potentially total loss of braking on one or more wheels. This represents a serious safety risk. Even minor corrosion weakens the hose connection and should be addressed promptly. Brake hose replacement typically costs £80-150 per hose but all four should be replaced as a set if corrosion is widespread.
Check brake disc condition for lipping or scoring. Test braking at moderate speed for pulling to one side or vibration through the steering wheel. Review MOT advisories for brake-related items.
MOT data shows this model fails at extremely high rates for suspension joint dust cover deterioration - up to 501 times the national fleet average. The rubber or plastic boots that protect ball joints and suspension bushes from dirt and water ingress fail prematurely on XK models. This appears to affect both the X100 and X150 generations across all mileage ranges but peaks in the 20,000-40,000 mile bracket. Once the covers fail, contamination accelerates wear of the underlying suspension components.
Failed dust covers allow water and road debris to contaminate suspension joints, accelerating wear and potentially causing premature failure of ball joints, bushes, and track rod ends. While not immediately dangerous, contaminated components will require replacement sooner than normal, with individual ball joints costing £100-300 each to replace.
Listen for knocking, clunking or rattling over bumps during the test drive. Inspect the underside for corroded or cracked suspension components. Check the MOT history for suspension-related advisories, which often predict future failures.
The X100 generation XK shows steering rack gaiter (protective boot) failure at up to 51 times the national average according to MOT data. These rubber boots protect the steering rack internals from contamination but appear to have durability issues on this model. The problem is most acute in the 20,000-40,000 mile range but affects cars across all mileage bands. Failed gaiters allow dirt and water into the steering rack mechanism.
Failed steering rack gaiters allow contamination of the rack and pinion mechanism, accelerating wear and potentially causing steering play or heavy steering feel. If left unaddressed, contamination can lead to complete steering rack failure requiring replacement at £800-1,500. The car remains safe to drive with failed gaiters in the short term.
During the test drive, check the steering for excessive play, vibration or pulling to one side. Listen for groaning or whining when turning the wheel at low speed. Power steering fluid level and condition should be checked on hydraulic systems.
MOT data shows XK models experience shock absorber bush failure at over 10 times the national fleet average, with the 5.0L X150 models particularly affected at higher mileages. The rubber bushes that mount the shock absorbers to the chassis deteriorate prematurely, causing knocking noises and reduced ride quality. This typically becomes evident after 40,000 miles and worsens with age rather than just mileage.
Worn shock absorber bushes reduce ride comfort and handling precision but do not represent an immediate safety risk. They allow the shock absorber to move excessively in its mounting, causing noise and reducing the shock's effectiveness. Left unaddressed, worn bushes can accelerate wear of the shock absorber itself and affect tyre wear patterns.
Listen for knocking, clunking or rattling over bumps during the test drive. Inspect the underside for corroded or cracked suspension components. Check the MOT history for suspension-related advisories, which often predict future failures.

Based on 50k real DVSA MOT tests, the Jaguar XK fails more often than average on several items. The biggest outlier is suspension ball joints worn at 1093x the fleet average, followed by front or rear fog lamp with a multiple light so... (296x).
When viewing a specific car, check its MOT history for recurring advisories in these categories. See the full Jaguar XK MOT failure breakdown for data at every mileage point.
Routine servicing (oil and filter change every 10k miles) typically costs £80–£120 at an independent garage.

The Jaguar XK has some well-documented weak points, including 1 safety-critical issue that demand careful checking. The right example, properly maintained, can still be a sound purchase — but cutting corners on the pre-purchase inspection is not advisable. The 2009-2013 X150 models with the 5.0-litre naturally aspirated V8 are considered the best, offering strong reliability, the most refined engine, and aluminium bodywork that eliminates rust worries. For X100 buyers, post-2002 4.2-litre cars with the improved six-speed ZF gearbox and steel cylinder liners are the safest choice.
