What is the most common reason for check engine light on a 2017 Lexus ES 300h?

• Common causes include oxygen sensor faults, catalytic converter inefficiency, misfires, vacuum or EVAP leaks, and fuel trim issues. These can show up as codes such as P0171, P0300, P0420 or EVAP-related codes.
• If left unaddressed, simple issues can escalate to costly repairs — for example, uncorrected misfires can damage the catalytic converter, which is significantly more expensive to replace.
