What owners say across generations

Mixed sentiment heavily dependent on generation and powertrain. The IS is widely recognized for its strong long-term reliability, comfortable ride, and luxury feel, particularly when compared to German competitors. However, significant and recurring criticisms

  • Carbon buildup on intake valves (IS 250 with 4GR-FSE engine) — causes loss of power, rough idle, poor fuel economy, requires periodic cleaning. Frequency: very frequent.
  • Water pump and front cover oil leaks (2GR-FSE V6 engine) — common failure requiring expensive repair (engine removal for front cover, ~20-25 hours labor). Frequency: very frequent.
  • Severe diesel engine issues (IS220d with 2AD-FHV engine) — chronic DPF filter and EGR valve clogging leading to very high fuel consumption, potential for catastrophic engine failure (head gasket, seals) especially with poor maintenance. Frequency: very frequent.
  • Steering lock ECU failure (early generations, e.g., 2008 IS 350) — causes no-start conditions, expensive diagnostic and repair process. Frequency: recurrent.
  • Fuel consumption discrepancy — real-world MPG often poor, with reports of 10-15 MPG in city driving for IS 300/350, significantly lower than EPA estimates. Frequency: recurrent.

Owner insights cover all generations of the IS.
