Is the Jaguar S-Type reliable?
The Jaguar S-Type has 11 known faults in our database, 5 of them rated high severity. The most serious are gearbox (the six-speed ZF automatic that replaced the original five-speed box has needed repeated) and gearbox (the five-speed automatic fitted to early S-Types is prone to failing at about 60,000 miles). None of them makes the car a bad buy on its own; the risk is a seller who knows and says nothing.
That is a count of the faults we hold, not a reliability score. Popular cars get written about more, and a newer generation has had less time to show its faults.
Which Jaguar S-Type years should you avoid?
No year is a write-off on its own. What matters is which serious faults a given year and engine can have, and whether the car in front of you has had them fixed.

Jaguar S-Type X200 (1999 to 2007) problems
Transmission/ClutchHigh severity📝 Editorial
The six-speed ZF automatic that replaced the original five-speed box has needed repeated software updates, and its torque converter has failed on a fair number of cars. Jaguar issued several bulletins covering harsh or lurching shifts (including the 3 to 2 and 2 to 1 changes), a squeal while changing gear under acceleration, and a bulletin warning that low oil pressure or a sticking valve could let the box select reverse while Drive was engaged. Some owners of three to five year old cars got a replacement gearbox with Jaguar covering most of the bill and the owner paying £770.
Rough guide
£770 (owner's share of a replacement gearbox with Jaguar paying the rest)
Typical symptoms
lurch or thump on part-throttle changes
harsh downshifts as the car slows to a stop
squeal or squeak during upshifts under load
shudder at steady cruising speeds from the torque converter

Transmission/ClutchHigh severity📝 Editorial
The five-speed automatic fitted to early S-Types is prone to failing at about 60,000 miles. The box can also feel sloppy in the J-gate and drop a gear on its own mid-corner.
Typical symptoms
slipping or flaring revs between gears
unexpected downshift in the middle of a bend
delayed engagement when selecting Drive or Reverse
Affected vehicles
Engines:
Original five-speed automatic (all engines)

Transmission/ClutchMedium severity📝 Editorial
The automatic gearbox fluid is cooled by a unit built into the engine radiator. If that internal cooler cracks, engine coolant mixes into the gearbox fluid and can ruin the automatic transmission.
Typical symptoms
coolant level dropping with no external leak
gearbox slipping or changing erratically
milky or pink contamination in the gearbox fluid or coolant

Engine/EmissionsHigh severity📝 Editorial
A small number of early V8 engines suffered Nikasil bore coating failure after 50,000 to 60,000 miles, losing compression. Jaguar replaced affected engines if the car was under five years old, had covered less than 100,000 miles and had a full Jaguar service history, cover that has long since run out. Engines built from September 2000 are not affected.
Typical symptoms
lumpy, uneven running
hard starting
loss of power from falling compression

The V8 engines have had problems with their timing chain tensioners, which shows up as a noisy timing chain.
Typical symptoms
clatter from the timing chain end, worst straight after a cold start
chain noise that quietens once oil pressure builds
Affected vehicles
Engines:
4.0 and 4.2 V8
Typical mileage:
unknown miles

ElectricalMedium severity📝 Editorial
Failed rear light seals and boot lid seals let water into the boot, which is where the battery lives, and the damp causes a range of electrical faults. The boot lock solenoid can fail from moisture, a damp and corroded boot open switch can trigger the alarm, and a faulty boot light switch can drain the battery.
Typical symptoms
wet carpet, or water pooling in the spare wheel well
boot won't open with the remote or button
alarm going off for no reason
battery flat after a few days parked

OtherMedium severity📝 Editorial
The electric parking brake fitted from the 2002 model year can fail to release fully, so the rear brakes drag. This wears the rear discs and pads out early, with discs lasting as little as 15,000 miles in some cases.
Typical symptoms
hot rear wheels after a short drive
car feels held back when pulling away
grooved or lipped rear discs well before they should be
parking brake warning light staying on
Affected vehicles
Engines:
All (electric parking brake from the 2002 model year)

Engine/EmissionsHigh severity📝 Editorial
Used mainly for short trips from a cold start, the 2.7 V6 diesel clogs its particulate filters. The extra fuel injected to burn them clean runs down the cylinder walls into the sump, thinning the oil and raising its level until the engine can start running on its own oil. Separately, a 2007 recall covered 2.7 diesels built between 2004 and 2007 whose particulate filter could overheat after a slow journey and create a fire risk.
Typical symptoms
particulate filter warning light
oil level rising above the full mark on the dipstick
engine oil with a diesel smell
power dropping away, or the car going into limp mode

Engines:
2.7 V6 diesel
Typical mileage:

Engine/EmissionsMedium severity📝 Editorial
The twin turbos on this 2.7 V6 diesel run extremely hot and their oil seals are prone to failing, especially when the engine is switched off straight after motorway driving, a long climb or towing without idling first. 2006 cars appear to have had a poor batch of turbos, and Jaguar issued a bulletin to replace them.
Typical symptoms
blue or grey exhaust smoke
oil consumption between services
whistle or tinkling noise from the turbos
loss of boost and power

2.7 V6 diesel (twin turbos)

Engine/EmissionsMedium severity📝 Editorial
At least one S-Type 2.7 diesel lost its big end bearings at four years old, shortly after a service and with the oil topped up, and the dealer recorded it as a component failure. This Ford-built V6 diesel family has a wider record of crankshaft bearing shells spinning and crankshafts breaking, mostly reported on the later 3.0 version in Land Rovers and the XF and XJ.
Typical symptoms
deep knock from low down in the engine
oil pressure warning
sudden seizure with little warning

Engine/EmissionsHigh severity📝 Editorial
The timing belt tensioner on this 2.7 V6 diesel is fixed to the oil pump housing. When the housing snaps or the tensioner fails, the belt is thrown and the engine destroys itself. Owners reported it on Land Rovers sharing the engine, including a Range Rover Sport that failed at 60,000 miles and a Discovery 3 at 88,000, and the S-Type 2.7 diesel has the same basic unit. One owner heard from a specialist that the oil pump should be upgraded at each timing belt change.
Typical symptoms
rumble from under the engine then loss of power
engine stops and won't restart

Jaguar S-Type buying questions
What are the most common Jaguar S-Type problems?
Three stand out. Gearbox: the six-speed ZF automatic that replaced the original five-speed box has needed repeated software. Gearbox: the five-speed automatic fitted to early S-Types is prone to failing at about 60,000 miles (typically 60000 miles). Engine: a small number of early V8 engines suffered Nikasil bore coating failure after 50,000 to 60,000 (typically 50000 to 60000 miles). The full list above is grouped by generation, with typical mileage and a rough repair cost for each.
Which Jaguar S-Type years should I avoid?
No Jaguar S-Type year is a write-off, but the X200 (1999 to 2007) carries the most serious faults: gearbox and engine. Year matters less than whether the specific car has had the known fixes, so check the history for them.
What should I check when viewing a used Jaguar S-Type?
Ask the seller about the gearbox and engine faults on this page and whether they have been fixed, with invoices. On the test drive watch for lurch or thump on part-throttle changes, slipping or flaring revs between gears and lumpy, uneven running. Read the MOT history for repeat advisories, then paste the advert into the free check, which reads it against all 11 known faults before you travel. Check a Jaguar S-Type advert →
What is the real MPG of a Jaguar S-Type?
Owners report 31.3 mpg on average across the Jaguar S-Type engines with data, about 98% of the official combined figure. The gap between official and real-world economy varies a lot by engine, so the Real MPG page lists every engine and generation separately, from 274 owner submissions.

If you used to check the Honest John “Good & Bad” section before the site closed in 2026, this page is where that information now lives. We rebuilt the Jaguar S-Type owner-report history from the archived Honest John dataset, added our own research, specialist and owner-club sources and DVSA recall data, and we keep it free. Each fault above is badged with its source. The same data feeds our free advert check, which reads a listing against every known fault for the exact engine and year.
Knowing what a Jaguar S-Type goes wrong with is half of it. The rest is reading the advert and checking the car's history before you hand any money over.
