Reliability & Common Issues

First Generation (XE10)

• Overall Reliability: Generally very reliable, especially the 2JZ-GE engine.
• Common Issues:
  • Valve Stem Seals: Can leak on higher mileage examples, leading to oil consumption and smoke.
  • Automatic Transmission: Can exhibit rough shifting or slipping in neglected examples. Regular fluid changes are crucial.
  • Suspension Components: Ball joints, control arm bushings, and sway bar end links are common wear items.
  • Crank Position Sensor: Known to fail, causing stalling or no-start conditions.
  • Rust: Susceptible to rust in areas with harsh winters, particularly around the rear wheel wells and undercarriage.
  • Instrument Cluster Backlighting: Bulbs can burn out, requiring replacement.

Second Generation (XE20)

• Overall Reliability: Generally reliable, but with some model-specific issues.
• Common Issues:
  • Carbon Buildup (IS 250): The 2.5L V6 is prone to carbon buildup on the intake valves due to its direct injection design. This can lead to rough idling, reduced performance, and eventual engine damage. Regular walnut blasting or chemical cleaning is recommended.
  • Water Pump Leaks: Water pumps can fail prematurely, leading to coolant leaks and potential overheating.
  • Door Lock Actuators: Known to fail.
  • Dash Cracking: Some reports of dashboard cracking, particularly in warmer climates.
  • Oil Leaks: Check for oil leaks around the valve covers and timing cover.

Third & Fourth Generation (XE30/XE40)

• Overall Reliability: Very reliable. These are newer models with generally fewer reported issues.
• Common Issues:
  • Water Pump Leaks (3.5L V6): Similar to the XE20, water pump leaks can still occur, though less frequently.
  • Turbocharger Issues (2.0T): Some isolated reports of turbocharger issues, such as wastegate actuator problems.
  • Infotainment System Glitches: Occasional software glitches or connectivity issues with the infotainment system.
  • Fuel Pump: On the earlier 2014-2015 IS models, there was a recall for fuel pump failure, which can cause stalling.

Driving Experience

First Generation (XE10)

The first-generation IS 300 is known for its sporty handling and responsive steering. The 2JZ-GE engine provides smooth and ample power.

• Years to Avoid: 2006-2008 IS 250 models due to higher risk of carbon buildup.
• What to Look For: Service history, evidence of carbon cleaning on IS 250, smooth automatic transmission operation, no water pump leaks, no dash cracks, test all electronics.
• Budget Tip: The IS 250 is typically less expensive than the IS 350, but factor in potential carbon cleaning costs.

Third & Fourth Generation (XE30/XE40)

• Years to Look For: 2017+ models for updated styling and features, fourth-generation (2020+) for improved handling dynamics.
• Years to Avoid: Early model year 2014-2015 IS models due to the fuel pump recall.
• What to Look For: Service history, test drive thoroughly, ensure all electronics are functioning properly, inspect tires for even wear.
• Budget Tip: Certified pre-owned Lexus vehicles offer extended warranty coverage and peace of mind.

General Advice: Always get a pre-purchase inspection (PPI) from a trusted mechanic before buying any used IS 300. A PPI can uncover hidden issues and save you from costly repairs down the road. Check the Carfax or similar vehicle history report for accident history and title issues. A well-maintained Lexus IS 300 can provide years of reliable and enjoyable driving.
