Anonymous A., NY (2018 Honda Civic EX-L 1.5-L 4 Cyl turbo)"A/C compressor failed. Symptoms first noted in April 2025 when A/C was turned on for the first time in Spring and did not cool. A hissing noise was heard whenever the compressor was supposed to be on. The compressor was replaced several days later."

Anonymous, MA (2018 Honda Civic Sport 2.0-L 4 Cyl turbo)"I am learning that there is a warranty on the AC condensor system in 10th Generation Honda Civics and need for new R1234YF Refrigerant. I am calling the Dealership where I purchased the vehicle new in 2018. Thank you."
Anonymous, WI (2018 Honda Civic LX 1.5-L 4 Cyl turbo)""This is the second time both the condenser and compressor had to be replaced since the cars purchase. While it was, again, covered by warranty, I fear it wont be if it fails again in two years.""

Anonymous A., VA (2018 Honda Civic Si 2.0-L 4 Cyl turbo)"This item is very expensive and difficult to get or remove from the vehicle"
Anonymous A., NC (2018 Honda Civic EX 2.0-L 4 Cyl)"This generation civic has 2 10-year unlimited mileage open recalls for failing compressor gasket seals and condensers. Other parts of the system (the evaporator in our case) seem impacted but Honda corporate denies this. Dealerships have attempted to tie warranty work to other, expensive, components. Warranty work is only available at dealerships. We have had 3 failures since purchasing the vehicle. 2 compressor gaskets and 1 condenser. Allegedly, the evaporator core needs replacing (a 6 hour job, dash out), but an independent shop confirmed it was not leaking."
