Summary
The 2024 Lexus IS300 appears to be a generally reliable vehicle, with most reported issues being relatively minor, primarily relating to the infotainment system or interior noises. The most concerning issue is the potential for rough shifting in the 8-speed automatic transmission paired with the higher-output V6 engine, which could lead to more significant repair costs if the valve body needs replacement. The cost of repairs appears to be fairly affordable but could potentially be costly if issues require more complex fixes.
