2025 Kia Carnival Hybrid Check Engine Light Codes

In Burlington, MA, Herb Chambers Kia of Burlington routinely sees a handful of common diagnostic trouble codes on the 2025 Kia Carnival Hybrid. Typical codes include P0171 (system too lean), P0420 (catalyst efficiency below threshold), P0300–P0304 (misfire), and P0455 (large EVAP leak). Left unresolved, these faults carry escalating costs: a lean condition can ruin oxygen sensors and catalytic converters over time, converting a modest sensor repair into a $1,000+ catalytic converter replacement; misfires can cause piston or catalytic damage that multiplies labor and parts costs; EVAP leaks often lead to failed emissions tests and repeat diagnostics. Our technicians explain these cost paths clearly and show how timely repair preserves fuel economy, avoids expensive repairs, and protects resale value. When you bring your 2025 Kia Carnival Hybrid to Herb Chambers Kia of Burlington, you get OEM diagnostics, genuine Kia parts, and a transparent estimate that highlights immediate and long-term savings.
