Misfire on other Soul years

Report counts are for each model year on its own, so a newer car has had less time to collect them.

What this problem usually is

These reports start with the check engine light. Many describe the engine running rough or shaking at idle, a P0300-series code, or a catalytic converter code. A worrying number say the light was flashing. Owners often list ignition coils or spark plugs already replaced, and the light coming back afterward.

What got replaced

Is this a known problem?

The manufacturer has sent NHTSA 1 service bulletin or notice for the 2017 Kia Soul that deal with this problem. Newest first.

Federal rules make a manufacturer send NHTSA a copy of any notice about a defect that goes to more than one dealer or owner. Most of these are service bulletins, the repair instructions manufacturers send to dealers. NHTSA generally leaves safety recall bulletins out of this file, and recalls are listed separately.

What owners wrote

“Perform check engine light diagnosis. Heard knocking noise at any speed even at idle. Added 2 quarts of oil. P0420 catalyst system efficiency below threshold Bank 1. The engine is consuming too much oil and has a noise coming from the valve train. Also, a slight rod bearing knock. Our auto mechanic had told us to check with Kia Dealership because it is a known issue on this vehicle. But the Kia declined to repair.”

Filed Sep 23, 2025

“Engine is running very rough. At a low idle, the engine turns off. Today the car turned off 11 times. A diagnostic reading shows all four cylinders misfiring.”

Filed Jul 1, 2025

“My kia has been having a issue with the check engine light on blinking after driving it over 30 miles... The car then slows down to 2rpm and I'm really concerned about this after 2other people I know are having that same problem.”

Filed Feb 2, 2023

“My Kia stalled it had thrown a rod there wasn’t any warning the oil had been changed routinely and there wasn’t any check engine lights on”

Should you keep driving it?

This page can't tell you that. 0 of 51 reports involved a crash. Owners who file are the ones who had a bad experience, and nobody checks their reports. If the problem affects steering, braking, power or a fire risk, treat it as a safety fault and have it inspected before a long or high-speed drive.

File your own report with NHTSA. Complaint counts are how a problem gets an investigation. How reports land on this sheet.
