P0353 on Kia by model: symptoms, diagnosis and fix
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.
Common Symptoms
- check engine light
- flashing MIL
- rough idle
- hesitation on acceleration
- engine shaking
- poor fuel economy
How to Fix
Scan for cylinder-specific misfire codes, inspect plugs for wear or oil fouling, and test or swap coils to isolate the fault. On early models, replace aged plug wires along with plugs; on later coil-on-plug setups, replace the failed coil and inspect the connector for corrosion. If misfires persist, check for vacuum leaks and compression issues before replacing more parts.

Frequently asked questions
What does P0353 mean on a Kia?
P0353 stands for "Ignition Coil C Primary/Secondary Circuit Malfunction." This is an ignition/engine code. An ignition coil converts the battery's low voltage into the high voltage needed to create a spark at the plug. P0353 means the engine computer detected a fault in the primary or secondary circuit of ignition coil 'C' — the expected feedback when the coil is commanded to fire is missing or abnormal. Typical effects are a misfire, rough idle, hesitation, or loss of power, and a prolonged misfire can overheat and damage the catalytic converter. On Kia it is documented across 1 model: Rio.
What are the most common causes of P0353?
The most common causes of P0353 are: Failed ignition coil 'C', Damaged wiring or corroded connector at the coil, Open or short in the coil primary/secondary circuit, Worn or fouled spark plug adding load to the coil, Poor power or ground supply to the coil, Faulty ignition driver in the ECM (less common). The specific cause varies by vehicle.
How much does it cost to fix P0353 on a Kia?
Published repair estimates on Kia range from $120 to $600 depending on the model and root cause. If an issue mentions a recall or campaign, check your VIN with the manufacturer or NHTSA and confirm eligibility and coverage with a dealer.
