P0324: questions drivers ask

What does code P0324 mean?

P0324 is a generic OBD-II powertrain code. Its standard definition is "Knock Control System Error". 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 6 car models.

Which cars get code P0324 most often?

In NHTSA owner complaints, P0324 is mentioned most for the Chevrolet Silverado (3), Chevrolet Spark (2), Chevrolet Cruze (1), across 6 models and model years 2013 to 2021. Popular models collect more reports because more of them are on the road.

Is there a recall for code P0324?

No NHTSA recall text names P0324 directly. 2 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 P0324?

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.
