P0301 on Mazda vehicles
P0301 identifies a misfire on cylinder 1. Mazda documented an ignition-coil issue in a specific group of vehicles with misfire codes and rough idle or reduced power.
Does Mazda bulletin 01-014/16 cover this vehicle?
Mazda lists certain 2013–16 CX-5s and 2014–16 Mazda3s and Mazda6s. Match your VIN and production date to the table. For a Mazda3, use the row for its assembly country.
Ask which coil supplier is installed. The bulletin identifies YUMEBISHI coils and distinguishes them from Mitsubishi coils. For later models or vehicles outside the listed ranges, ask for a diagnosis for your model year before ordering parts.
Is it safe to drive a Mazda with P0301?
No. P0301 is a high-severity code — avoid driving your Mazda 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.
