The IS 250 is the petrol version of the second-generation Lexus IS, a compact executive saloon built to take on the BMW 3 Series and the Mercedes-Benz C-Class. In Europe it was sold with the 2.5-litre 4GR-FSE V6 across the whole XE20 run, from launch in late 2005 until saloon production ended in April 2013, surviving both mid-life updates while the diesel range was reshuffled around it. Buyers could choose a six-speed manual or a six-speed torque converter automatic, always with rear-wheel drive, and the same engine also powers the IS 250C convertible, which stayed on sale after the saloon finished; the mechanical content of this report applies to it as well.· more· less
Durable naturally aspirated V6Timing chain, no belt to replace
Direct injection carbon buildupLimited European dealer network
Buy if: You want a rear-drive compact executive with a chain-driven naturally aspirated V6, and you can budget for periodic intake valve cleaning as a maintenance item rather than a surprise.
Avoid if: Your driving is almost entirely short urban trips, which accelerate the intake deposits this engine is prone to, or you need cheap servicing from any independent garage.

Intake valve carbon buildup (4GR-FSE direct injection)
€500 - 1,2001 of 9
Direct injection only, so no fuel washes the intake valves and deposits accumulate on every one of these engines · more· less
The 4GR-FSE is a D-4 direct injection engine and, unlike the larger 2GR-FSE fitted to the IS 350, it has no additional port injectors. Nothing washes the back of the intake valves, so oil vapour drawn in through the crankcase ventilation system and soot returned by the exhaust gas recirculation bake onto the valve stems and seats every time the engine gets hot. The deposits disturb and restrict airflow into the cylinder. Symptoms build gradually: an uneven or shaky idle that is worst when cold or with the air conditioning running, hesitation at light throttle, longer cranking, misfire codes in the P0300 range and a check engine light. Most cars start showing this somewhere between 100,000 and 150,000 km, much earlier on short-trip urban cars and later on ones used mainly on the motorway. The proper fix is to remove the intake manifold and blast the valves with walnut shell media, which costs roughly €500-900 at a specialist and more at a Lexus dealer; cars that also need injector cleaning or new intake gaskets sit at the top of that range and severe cases reach €1,200. Spray-in cleaners poured through the intake tract give only partial results because the deposits are hard and baked on. Lexus acknowledged the problem in the United States through Customer Support Program ZLA, which paid for intake valve cleaning for up to nine years from first registration on 2006 through certain 2010 IS 250 and IS 250C cars. That programme was a US filing, it has expired, and no European equivalent is documented, so budget for the work yourself. Many specialists suggest cleaning every 60,000-80,000 km as maintenance rather than waiting for misfires.
Front and rear suspension bushing and arm wear
€400 - 1,0002 of 9
Double wishbone front and multilink rear bushings perish with age, causing knocking and uneven tyre wear · more· less
The XE20 IS uses a double wishbone front and a multilink rear suspension with a large number of separate arms, and the rubber bushings in them harden and crack with age rather than with mileage. On cars that are now well past fifteen years old this is one of the most common reasons for a failed periodic inspection. Symptoms are a knock or clonk over broken surfaces and expansion joints, steering that wanders slightly on the motorway, and feathered wear on the inner tyre shoulders. Individual bushings are cheap, but on this suspension most workshops fit the complete arm because the bushings are pressed in. A pair of front lower arms fitted runs about €400-600; adding the rear upper and lower links and a four-wheel alignment takes the job to €800-1,000. Anti-roll bar drop links are a separate and much cheaper item that often gets blamed for the same noise, so have the source of any knock identified properly before agreeing to a full set of arms. Ask for the car to be put on a lift and the arms levered before you buy, because this is one of the largest predictable bills on a car of this age.
Valve cover gasket and cam sensor seal seepage
€300 - 6003 of 9
Hardened rubber gaskets let oil seep from both cylinder head covers on the V6 · more· less
On a V6 of this age, valve cover gasket seepage is expected rather than unusual. Oil weeps from the joint and can run down onto the exhaust manifolds, producing a hot oil smell after a drive and, in bad cases, a wisp of smoke from the engine bay. The camshaft position sensor O-rings in the same area leak for the same reason and are often replaced at the same time. Neither part is expensive, but the V6 layout means the intake plenum has to come off to reach the rear bank, so labour dominates the bill. An independent specialist typically charges €300-450 for both covers, a Lexus dealer €500-600. It is worth having this done while the intake is already off for carbon cleaning, which saves a large part of the labour. Seepage on its own is not urgent, but oil sitting against a hot exhaust manifold should not be left indefinitely.
Water pump and thermostat coolant leak
€350 - 7004 of 9
The belt-driven mechanical pump weeps coolant from its shaft seal at high mileage or high age · more· less
The 4GR-FSE uses a conventional mechanical water pump driven by the accessory belt, not an electric pump, so failure is gradual rather than sudden and gives plenty of warning. The shaft seal weeps and coolant shows up as a crusty pink or orange deposit below the pump, while the level in the expansion tank drops slowly over months with no puddle on the driveway. A worn bearing sometimes adds a faint whine that rises and falls with engine speed. Most cars that need this are past 150,000 km or simply past fifteen years old, whichever comes first. Replacing the pump together with the drive belt, the thermostat and fresh coolant costs about €350-500 at an independent specialist and up to €700 at a Lexus dealer. Access on this longitudinally mounted V6 is reasonable, which keeps the labour sensible. Check the expansion tank level and look for residue on the front of the block before you buy.
Direct injection fuel system: injector fouling and pump wear
€400 - 1,2005 of 9
Injector tips foul inside the combustion chamber and the camshaft-driven high-pressure pump wears at high mileage · more· less
This engine's injectors spray directly into the combustion chamber at high pressure, so the tips sit in soot and their spray pattern degrades over time. A fouled or partly blocked injector causes a persistent misfire on one cylinder that does not clear after the intake valves have been cleaned, which is the usual way owners discover it. Ultrasonic cleaning and reseal of a full set costs €250-400; a single replacement injector is roughly €250-350 fitted, and a car needing several adds up quickly. The camshaft-driven high-pressure fuel pump is a separate wear item at around €500-800 fitted, and gives long cranking, a hesitant restart when hot and fuel pressure faults as it deteriorates. Neither of these is anywhere near as widespread as the carbon problem, and there is no documented European service campaign for either, so the cost falls to the owner. Both become more plausible once a car is beyond 200,000 km. If a cylinder still misfires after a proper intake clean, have the injectors flow-tested rather than assuming more carbon.
Automatic gearbox shudder and delayed engagement
€300 - 2,8006 of 9
The A960E six-speed is durable but suffers lock-up shudder and harsh shifts when its fluid is never changed · more· less
This applies only to cars fitted with the automatic; the six-speed manual is an entirely different unit. Lexus treated the A960E's fluid as a fill for the life of the car, and a great many examples have never had it touched. On a fifteen-year-old car that fluid is well past its useful life. The first symptom is a light shudder under gentle acceleration at roughly 60-90 km/h as the torque converter lock-up clutch slips, followed by delayed or firm engagement into drive and reverse. A drain and refill with genuine Toyota WS fluid costs €200-300 and often improves the shudder noticeably if it is caught early, though a gearbox that has already been neglected for 200,000 km is a poorer candidate. If it is ignored, worn friction material circulates and damages the valve body, which is €800-1,200 to replace, and a full rebuild is €2,000-2,800. Outright failure of this gearbox is uncommon, so documented fluid changes are worth paying a premium for.
Clutch and flywheel wear (manual cars)
€900 - 1,8007 of 9
The manual car's clutch is a gearbox-out job and the flywheel is often replaced alongside it · more· less
This applies only to the six-speed manual, which was offered alongside the automatic in Europe and is much less common on used forecourts. Clutch life depends heavily on how the car has been used: examples that spent their lives in traffic can need one by 130,000-150,000 km, while motorway cars go considerably further. Warning signs are a high or vague biting point, engine revs rising without matching acceleration when you accelerate hard in a high gear, and a judder as the clutch takes up from rest. The gearbox has to come out, so labour is the larger part of the bill. A clutch kit fitted at an independent specialist runs about €900-1,300; if the flywheel is replaced rather than reused, the total moves towards €1,600-1,800. Ask directly whether the clutch has been done and at what mileage, and test the biting point on a hill during the test drive.
VVT-i oil control valve sticking
€200 - 5008 of 9
Camshaft timing solenoids clog with sludge, giving rough running and P0011 or P0021 fault codes · more· less
The 4GR-FSE has dual VVT-i, adjusting both the intake and the exhaust camshafts on both banks, so there are several oil control valves regulating oil pressure to the cam phasers. Their fine internal screens clog when oil change intervals have been stretched or the wrong grade has been used. The car then idles roughly, may rattle briefly on a cold start as a phaser fails to hold position, loses a little low-end response, and stores a camshaft timing fault such as P0011 or P0021 for bank one or bank two. One valve fitted costs around €200-300; if more than one is replaced, or the phaser itself turns out to be at fault, the bill reaches €400-500. This is largely a maintenance-history problem, and cars serviced on time with the correct grade rarely see it. Ask which oil has been used and how often it has been changed, and treat a car with no oil change records as higher risk here.
Dashboard and soft-touch trim degradation
€400 - 1,5009 of 9
The rubberised dash coating can turn sticky and glossy on cars that have lived in strong sun and heat · more· less
Toyota and Lexus used a soft-touch coating on dashboards and interior trim in this era that breaks down under prolonged heat, humidity and UV exposure, becoming tacky, shiny, or in bad cases visibly wrinkled. It is by far the most reported interior complaint on 2007 and 2008 IS 250 cars in hot markets, and the complaint volume is heavily concentrated there. Northern European cars that have been garaged are rarely affected, so the ones to inspect closely are cars that have spent their lives in southern Europe or have been imported from a hot climate. Professional refinishing or a fitted wrap costs €400-800; a replacement dashboard assembly with the labour to fit it reaches €1,200-1,500 because the whole facia has to come apart. Lexus ran a dedicated customer support programme for this in the United States, which has expired, and no European equivalent is documented. Run your hand across the top of the dashboard and the trim around the instrument binnacle before you commit.
Dependable V6 with one recurring direct injection cost
The 4GR-FSE is a chain-driven naturally aspirated V6 with a strong bottom end, and well-maintained examples cover 250,000 km and more without serious powertrain work. What shapes ownership is the intake valve carbon buildup, which is less a defect that either appears or does not and more a deposit the direct injection layout accumulates by design, so it has to be cleaned off periodically. The rest of the car ages the way any well-built rear-drive saloon of this era ages: perished suspension bushings, weeping gaskets, and an automatic gearbox that wants fluid it was never officially scheduled to receive. Total running costs sit well below a comparable German rival from the same years, but parts and genuine specialist knowledge are thinner outside major cities.
Service history
Complete Lexus dealer or specialist records essential. Verify oil changes at the recommended interval with the correct grade.
Tires
Check tread depth, age codes and uneven wear. Rear tyres wear faster on this rear-drive car, and staggered 18-inch sets cannot be rotated front to back.
Cold start
Start the engine completely cold. Listen for a brief cam phaser rattle and watch how long the idle takes to settle.
Test drive
Minimum 30 minutes including motorway speeds. Assess the gearbox through all six ratios and check for vibration at speed.
Specific for this vehicle
Ask for evidence of intake valve cleaning
An invoice for walnut blasting, with the mileage, is the single most valuable document on this car. No record on a high-mileage example means you should assume the work is still to come.
Assess warm idle quality with the air conditioning on
Let the engine reach operating temperature, switch the air conditioning on and watch the idle. Shaking, hunting or a faint stumble points to carbon on the intake valves.
Scan for stored and pending misfire codes
Ask for a scan tool reading. Codes in the P0300 range, especially repeating on the same cylinder, indicate carbon deposits or a fouled injector. Pending codes matter even if no light is showing.
+ 6 more checksShow less
Check the oil level and ask about top-ups
Note the level before and after the test drive. Ask how much oil goes in between services, because oil drawn through the crankcase ventilation is what feeds the intake deposits.
Have the suspension arms and bushings checked on a lift
Get the front lower arms and the rear links levered while the car is raised. Cracked or split bushings are the most common large bill on cars of this age.
Automatic cars: feel for torque converter shudder
Accelerate gently at 60-90 km/h and feel for a light vibration through the floor. Then ask for records of any gearbox fluid change, because most cars have never had one.
Manual cars: check the clutch bite point and history
Pull away on an incline and note where the clutch engages. A very high or vague bite point, or revs rising without acceleration in a high gear, means a gearbox-out job is due.
Inspect the dashboard and soft-touch trim
Run your hand across the top of the dashboard and the trim around the instruments. Tacky or glossy surfaces are expensive to put right and point to a car from a hot climate.
Confirm the airbag, fuel pressure sensor and wiper arm campaigns with the VIN
Have a Lexus dealer check the VIN against all three. Applicability of the Takata inflator recall is decided by VIN rather than by model year, so a build-date estimate is not sufficient.
Recalls and Technical Service Bulletins
Fuel pressure sensor may have been inadequately tightened and can leak fuel. Toyota Motor Europe campaign 1KBA-001, covering GSE20 IS 250 cars built 31 August 2007 to 3 February 2009; the remedy is retightening the sensor and replacing its gasket where necessary. Applicability is settled by VINCritical - verify completed
Takata airbag inflator replacement (European IS production 2005-2011, final applicability determined by VIN)Verify with VIN
Front wiper arm retaining nuts may loosen so the wipers stop working (2013 campaign, left-hand-drive IS 200d, 220d and 250 built June 2005 to September 2011)Verify completed
Contact a Lexus dealer with the VIN to verify that all three campaigns have been completed, because final applicability of the Takata inflator recall is determined by VIN rather than by model year alone, the fuel pressure sensor campaign covers only cars built between 31 August 2007 and 3 February 2009, and the wiper arm campaign was issued for left-hand-drive cars. Toyota and Lexus carry out recall work free of charge regardless of the vehicle's age or how many owners it has had. Note that the intake valve cleaning programme that existed for this engine was a United States customer support programme rather than a recall, so a European VIN check will not show it.
Warranty Status
Factory warranty (3 years / 100,000 km)Expired on every XE20 IS 250. The 100,000 km cap applied in most EU markets; national terms varied
Lexus Relax extended cover (terms set nationally)Market-specific. In Germany, Lexus Relax currently runs to 15 years or 250,000 km and can be activated again at a Lexus service even where a service was missed or carried out outside the Lexus network, so a late XE20 first registered in Germany is not automatically outside it
Corrosion perforation warranty (12 years)Expired on every XE20 IS 250
Intake valve cleaning support programme ZLA (US market only)Covered 2006 to certain 2010 IS 250 and IS 250C cars for 9 years; expired, and no European equivalent is documented
Every XE20 IS 250 is well outside its original three-year Lexus warranty, and the 12-year anti-perforation cover has now run out on the last cars built as well. What can still be live is Lexus Relax, the cover a Lexus dealer renews at each annual service, and its terms are set nationally rather than Europe-wide. In Germany it currently runs to 15 years or 250,000 km and can be activated again at a Lexus service even where a previous service was missed or done outside the Lexus network, so a late German-registered car is not necessarily expired or permanently ineligible. Other markets set shorter limits, so ask your national Lexus importer to confirm the position for the specific VIN before you count on it. Third-party used car warranties are available, but read the exclusions carefully, because carbon cleaning, gasket seepage and suspension bushings are normally treated as wear and excluded.
