P0350 on Kia
Ignition Coil Primary/Secondary Circuit Malfunction
P0350 on Kia vehicles indicates ignition coil primary/secondary circuit malfunction. Au7o has documented this code across 1 Kia model — most commonly on Rio. This is a generic code indicating the engine computer detected a fault in an ignition coil's primary or secondary circuit. The computer monitors the coil control circuits that fire the spark plugs; when the expected electrical activity is missing or abnormal, this code sets. Because it does not always specify which coil, related cylinder-specific codes may also be present. It typically causes misfires, rough running, hesitation, hard starting, and reduced power. Typical repair costs on Kia range from $120 to $600, depending on the specific model and root cause.
Common Causes of P0350
- •Faulty ignition coil or coil pack
- •Wiring or connector fault in the coil circuit
- •Open or shorted coil primary/secondary winding
- •Faulty spark plug or plug wire
- •Poor ground or power supply to the coil
- •Damaged PCM ignition driver circuit
- •Corrosion or moisture in coil connectors

- Ignition Coil and Plug Wire Failure Causing Misfire, Hesitation, and Check Engine Light2001-2011
Across both generations of Rio, owners frequently report ignition-related misfires caused by failing coil packs, deteriorated plug wires on earlier cars, or worn spark plugs. The problem typically shows up as rough idle, hesitation under load, flashing MIL, and poor fuel economy. It is common enough in owner complaints and repair forums to be considered a recurring Rio issue, especially as these cars age.
