What 2016–2021 Civic owners report about the engine and engine cooling

Owners have filed 17 complaints with NHTSA, the US federal vehicle-safety regulator, that mention the radiator, coolant leaks or overheating on the 2016–2021 Honda Civic, and 11 filed under its engine and engine cooling. Those 17, by model year, as of September 18, 2026:

• 2016 Civic: 7 complaints

• 2018 Civic: 3 complaints
• 2019 Civic: 1 complaint
• 2020 Civic: 2 complaints
• 2021 Civic: none

NHTSA publishes complaints as owners wrote them and does not verify them, so read them as a pattern rather than a diagnosis.

A 2016 Civic owner, NHTSA complaint 11693315: "Blown Head gasket failure due to coolant leak into cylinders Evaporator Leak for A/C due to condenser and compressor shaft."

A 2017 Civic owner, NHTSA complaint 11608495: "A/C Evaporator went bad. Dealership already replaced other A/C components as part of extended warranty/recalls. However, the evaporator is not covered by the extended warranty. Could lead to incredibly high temperatures within the car or other components failing/overheating."

Recalls that cover the radiator cooling pack on the 2016–2021 Civic

As of September 18, 2026, NHTSA lists no recall on the 2016–2021 Honda Civic whose defect is in the radiator cooling pack. If your car has a warning light or a symptom that a recall could explain, check the VIN at nhtsa.gov/recalls anyway — it takes a minute.

Which radiator cooling pack a 2016–2021 Civic takes

Radiators differ by engine, by transmission, since an automatic's cooler often runs through the radiator, and by towing package. The 2016–2021 Honda Civic came with several powertrains, among them 1.5L I4 CVT FWD, 2.0L I4 CVT FWD and 2.0L I4 Manual FWD. That is why we ask for the VIN, or the year, engine and trim, and confirm the part against it before you pay rather than after it arrives.
