From Dog and Lemon Guide
Fuel system problems
Recall - Lexus IS250 & 350 models build between 15 Dec 03 & 16 Dec 05
- Fuel line may crack and leak. If the problem has been fixed in Japan there will be yellow paint above the centre of the chassis number inspection.
Recall - Lexus IS250 built between 21 Dec 04 & 27 Oct 05
2 fuel pipes on the engine may crack and leak
Engine problems
- All the engines in these cars use VVTI (Variable Valve Timing with Intelligence) will not forgive poor maintenance. The camshafts on there engines are regulated by tiny oil holes inside the shaft. If the engine oil is not changed religiously, these tiny oil holes will clog, the engine will not work properly and internal damage my occur,
- The engine coils will begin to fail with age, causing the car to misfire and run roughly. The coils are a bit pricey, particularly if you decide to replace all four.
- At high millage, all engines may require replacement throttle bodies, throttle position sensors and air flow meters.
- The throttle bodies on BEAMS engines commonly fail sometime after 90,000kms. These are not cheap replace, new or secondhand.
- The 'S‘ series engine (e.g., 3S-FE) are prone to oil leaks from the oil pump at high mileages, especially if the oil hasn't been changed. This problem may be caused by a leaking O-ring on the pump or a leaking seal behind the pump. The leaks take a long time to get serious and the problem can usually be solved by replacing the oil pump seal and O-ring while the timing belt is being placed (please note that silicone sealers and gasket compounds generally won't stop this oil leak for very long time, and therefore many garages insist on using a genuine Toyota O-ring, which often isn't cheap).
- Timing belts are prone to failure somewhere between 100,000-150,000km and should be replaced along with their tensioners or they may break.
Gearbox & drivetrain problems
- Clutches shudder on some IS200 models, and this problem is not necessary solved by replacing the clutch components. Left too long it can damage the precise six-speed gearbox. It's best to simply avoid example which shows the slightest hint of this problem.
- Transmissions give the normal wear and tear problems. That's is, they're built okay, but many are now at quit high mileages, and nothing last forever.
Steering and suspension problems
- Aside from normal wear and tear, any clonking noises in the suspension are likely to be caused by worn sway bar links.
Brake and safety problems.
Recall - Automatic models built in 1999
- Brakes may not work properly at engine startup, because of a lack of vacuum build-up in brake booster.
Recall - IS220 & 250 models built before 14 Jun 05
- The front seatbelt retractors may jam. If this problem has been fixed in Japan, there will be yellow paint above the frame number in the engine bay.
Body problems
It's worth checking for badly repaired accident damage, because many performance versions have been pranged, and not always fixed properly. Be particularly alert for uneven tyre wear. and don't buy any example in this condition unless it goes through a wheel alignment check first.
Interior problems
CD players swallow CDs on early models. Bring an expendable CD with you and try out the player before you buy, as a suitable replacement may not be cheap.
Electrical problems
Although the electronics on these cars are well made and generally durable, they give their share of problems. Check that each of the features actually works (e.g., air conditioning), and get a heavy discount for those that don't work. Get a quote for repairs before proceeding with the purchase of any version with dodgy electronics, as the price for repair may make your eyes water. |
