The systems that tend to fail first on the 2009 Lexus IS, with the typical mileage window when each becomes a concern. Detailed repair-cost ranges and exact what-to-check inspection notes are in the full report.

1
Engine (IS 250 Carbon Buildup)moderate~60,000-100,000 mi

Due to its direct-injection-only design, the 2.5L V6 (4GR-FSE) is prone to excessive carbon buildup on the intake valves, leading to misfires, rough idle, reduced power, and eventually 'check engine' lights. This requires specialized cle…

2
Interior (Dashboard Cracking/Melting)major~50,000-100,000 mi

A widespread and well-documented issue where the dashboard material deteriorates, becoming sticky, shiny, or cracking significantly, especially in vehicles exposed to hot sun. Lexus offered extended warranties/recalls in some regions, bu…

3
Cooling System (Water Pump)moderate~80,000-120,000 mi
