2022 Lexus RC F Check Engine Light Codes

Common check engine light codes for a 2022 Lexus RC F in Hingham include P0300 (random/multiple cylinder misfire), P0420 (catalyst efficiency below threshold), P0171/P0174 (fuel trim/air-fuel imbalance), and various oxygen sensor or EVAP codes. Left unaddressed, a P0300 misfire can damage pistons and the catalytic converter, driving repair costs into the thousands. A failing catalytic converter (P0420) is costly if the cause was prolonged ignoring of upstream faults. A battery or alternator issue that causes voltage fluctuations can lead to misleading codes and poor engine performance; replacing a weak battery now prevents broader electrical and engine-management damage and reduces lifetime maintenance expense. Herb Chambers Lexus of Hingham offers accurate code interpretation, OEM parts, and clear, cost-saving recommendations that are often less expensive than independent shops when you factor in warranty coverage and repair longevity.
