Showing the 60 model years where P0300 appears most; it is on file for 640 in total.
A model year appears here because the code is named in its record, not because every one of these vehicles sets it. Counts are mentions in the federal files, not failure rates — nobody publishes the denominator.
What it gets filed under
When owners report it
miles, typically
Half of the 41 owner reports naming P0300 that carry an odometer reading fall between 7,000 and 81,000 miles. A code that shows up at 30,000 miles is a different proposition from one that shows up at 130,000, and that difference is the single most useful thing in this record.
What owners said
Source: NHTSA complaint databaseOwners’ own words, one per nameplate, scrubbed of anything identifying. These are unverified reports filed with NHTSA — they are what was said, not a finding that it was true.
The diagnostic scan showed P0172 (Fuel System Too Rich, Bank 1), P0300 (Random/Multiple Cylinder Misfire), P0301 (Cylinder 1 Misfire), P0302 (Cylinder 2 Misfire), and P0303 (Cylinder 3 Misfire)
I then took the vehicle to an auto-parts store, where an OBD-II scan produced multiple diagnostic trouble codes, including P0300 engine misfire and several MAP-sensor-related codes
On XXX, Galeana Kia of , replaced the fuel injector on cylinder 3 under fault codes P0300 and P0303 and returned vehicle as "operating as designed." I paid for this repair out of pocket
Misfire on 2 cylinder, noise on start up diagnostic code P0300 P0302 P050 I was driving home and the engine started making a strange sound, vehicle would could no increase speed normally
vehicle may experience driveability issues, which may result in DTCs P0300 (random misfire detected), P0301 (No

What P0300 means
Source: SAE J2012 / OBD-IIMisfire detected, but not isolated to one cylinder.
A stored code names the test that failed, never the part that caused it. It is the starting point of a diagnosis, not its conclusion — the same code has several possible causes and the cheap one is not always right.
Common questions about P0300
Source: NHTSA files and the OBD-II standardCan I keep driving with P0300 stored?
Nobody can answer that from the code alone, and a site that does is guessing. A steady light generally means the fault was logged and the vehicle is in a reduced-risk mode; a flashing light means stop soon, because a misfiring engine can destroy a catalytic converter in minutes. The safe read of this page is the mileage and the components, not permission.
Does a code mean the car is recalled?
No. Recalls are filed by campaign and matched by VIN, and none of them are triggered by a scan tool. If you want to know whether an open recall applies to one specific vehicle, check the VIN at nhtsa.gov/recalls — that is the only source that settles it.
Why do the counts here differ from other sites?
Because these are not estimates. Every number on this page is a count of documents in NHTSA's own files: manufacturer communications that name the code in their filed summary, and owner complaints that name it in the narrative. We do not model, weight or extrapolate them.
Will clearing the code fix it?
Clearing turns the light off and erases the freeze-frame data a technician would have used to work out what happened. If the condition is still there the code returns, usually within a few drive cycles, and the diagnosis now starts from less information than before.
