The vehicle in question has the coolant intrusion into cylinders 2 and 3 with rough idle on startup, P0300, P0302, P0303, and white smoke on startup. The vehicle now has 111339 miles on it and the out of pocket cost is more than what the vehicle blue books for in excellent condition. TSB 22-2134 speaks to all the issue and what the repair is. If this is a known issue then I feel this should be a vehicle recall by Ford due to the costly repair.

While driving the vehicle at highway speeds the vehicle starts to lurch or randomly lose power. Eventually, within a few minutes, the lurching gets worse and the check engine light starts flashing. In a GM vehicle, a flashing check engine light is critical engine failure. After pulling the vehicle to the side of the road, the check engine light stops flashing and stays on constantly. After about 10-15 minutes, the check engine light turns off completely. The GM dealership can read the history and says it's P0300 error code for General Engine Misfire in cylinder #6. GM warranty refuses to fix anything because the light isn't on when the car comes into the dealership. The car has been to two…

P0300: questions drivers ask

What does code P0300 mean?

P0300 is a generic OBD-II powertrain code. Its standard definition is "Random/Multiple Cylinder Misfire Detected". The code tells you which system set the fault, not which part failed; the owner reports on this page show what it meant in practice for 50 car models.

Which cars get code P0300 most often?

In NHTSA owner complaints, P0300 is mentioned most for the Ford Escape (37), Chevrolet Silverado (21), Ford Fusion (20), across 50 models and model years 2012 to 2026. Popular models collect more reports because more of them are on the road.

Is there a recall for code P0300?

No NHTSA recall text names P0300 directly. 8 recalls on the cars that report this code concern the same component owners name most (Engine); they may or may not relate to the code. Check your VIN at nhtsa.gov/recalls.

What should I do if my car shows P0300?

Write down when the code appeared and what the car did (warning lights, loss of power, noises, speed, weather). Check your VIN for open recalls at nhtsa.gov/recalls, ask a dealer or independent workshop to read the stored freeze-frame data before anyone clears the code, and keep the repair order. If the car loses power in traffic, stop driving it. CarHooq does not diagnose: these are owner reports and official recall notices, not repair advice.

How this page was made

CarHooq read the text of every owner complaint filed with NHTSA for 19 US and European brands (model years 2012 onwards) and picked out the diagnostic trouble codes owners wrote down. This page lists every mention of P0300 (including sub-code forms such as P030085). The definition is the generic SAE J2012 wording; a carmaker may use the code slightly differently. Nothing here is a diagnosis. Data: NHTSA Office of Defects Investigation (public domain), retrieved November 3, 2026. How CarHooq reports are made.
