P0301 on Kia vehicles
P0301 identifies a misfire on cylinder 1. For some Forte owners, Kia has published a service action with specific engine and VIN criteria.
Which Fortes does SA321 cover?
Kia lists certain 2017–18 Forte (YDm) vehicles with the 2.0L MPI engine, built from May 16, 2016 through September 7, 2017. Ask a Kia dealer to check your VIN against the affected list.
If your VIN qualifies, share the recorded codes with the technician. Kia specifies different procedures depending on whether a misfire code is stored. For a different engine or model, use its own misfire diagnostic procedure.
Is it safe to drive a Kia with P0301?
No. P0301 is a high-severity code — avoid driving your Kia until it is diagnosed and repaired, as it can indicate an unsafe condition or risk further damage.
For other possible causes and diagnostic steps, see the general P0301 guide.
