2021 Hyundai Palisade Check Engine Light Codes

The 2021 Hyundai Palisade commonly reports codes such as P0420 (catalyst system efficiency), P0133/P0136 (oxygen sensor issues), P0300 (random/multiple cylinder misfires), P0456 (EVAP small leak), and P0171 (system too lean). If ignored, these conditions can escalate quickly: an unresolved misfire may overheat and damage the catalytic converter leading to a repair cost in the thousands; a failing oxygen sensor left in service reduces fuel economy and increases emissions; EVAP leaks can cause failed emissions tests and drivability complaints.
