2020 HONDA CIVIC — Problems, Recalls & Safety Data

Clutch started slipping all of a sudden. Check to see if it was under warranty said the warranty had expired because the car was over 36,000 MI did not know about the extended clutch warranty at the time that Honda was extending it due to defective parts so we replaced it ourselves. Upon tear down it was discovered that the clutch disc was only about 30% worn down there were no hot spots in the flywheel or the clutch cover so the problem was related to the holding force of the clutch cover have we continued to drive the car the way it was it would have burnt it up because it would barely move. I've been in Autotech for 50 years never seen a clutch slipping with this much material left on it and the parts in this condition it is obviously a defect with the part and I submitted a claim to Honda and they denied it had I had known Honda would have taken care of it I would have brought it to them.

Fuel pump issue. There is an active recall for this make and model but this vin isn’t included. The car will be fine and either completely shut down or once parked it won’t restart. After about an hour it will start and be fine. We took to a local mechanic who diagnosed the fuel pump. Said there was a recall so we went to the local dealership. They said it isn’t included and they can’t get the fuel pumps as they are being held for recalls only. The car continues to have this issue which is unsafe. I’ve contacted Honda corporate who are trying to get a fuel pump for us. We believe this should be included in the recall and should be looked into further I’m listing the most recent incident date but it’s happened at least 20 times since August 2025

This model Civic Si was build by Honda with a defective clutch. Mine began to fail at less than 60K miles. It started in the higher RPM 5K to 6K in the taller overdrive gears. This clutch design was unable to support the torque of the motor, which led to its premature failure. It's well documented in Honda forums that the clutch is weak and prone to early failure. It usually starts to fail in the upper gears under moderate acceleration. Once it starts to fail it does become a problem. Honda appears to be aware of the problem as they did have a TSB out that allowed for replacement for 5 years of 60K miles. However, reports on the internet seem to state Honda charges $2K just to tear down the car to look at the clutch. My car was low mileage and still hasn't hit 60K miles but outside the 5 year warranty. However, even if Honda had agreed to replace the clutch they reportedly leave the original dual mass flywheel, which would contribute to a shorter life span for the new clutch they just installed. The OEM manufacturer Exedy won't sell you the same clutch that Honda put into this car, and will only sell you the clutch from the type R. Thus it does appear clear that both Exedy and Honda were fully aware of the manufacturer defective clutch. A clutch like this should last over 100K miles. However, Honda rather then recalling them appears to have just thrown it to the wind and is willing to just let whatever happens pan out and see what's left . The failure of this clutch once it starts to slip does appear to be a relatively short process before total failure. Although it appears there has been no deaths so far there is a good chance someone will delay replacing that clutch because of cost, which could lead to a severe auto-accident or death. Even if Honda doesn't want to do a recall or reimburse their car owners they should at least issue an alert to owners about their defective clutch with free inspections. Respectfully submitted.

The air conditioning system in my 2020 Honda Civic EX has a refrigerant leak at the evaporator assembly, causing very weak or almost no cooling even when set to the lowest temperature settings. This happens consistently, including in moderate to hot outside temperatures, making the cabin uncomfortably warm during drives as it could get pretty hot in inland southern California. The A/C evaporator assembly is the failed component, and the part remains in the vehicle available for inspection if requested. This issue creates a safety risk because reduced visibility from window fogging in humid or rainy conditions (due to lack of proper dehumidification and cooling) can impair safe driving. In extreme heat, it also increases driver fatigue and distraction from discomfort. The problem was confirmed by a Honda dealership through diagnostic testing, which identified the evaporator leaking refrigerant. They previously repaired a related condenser leak under warranty, but the cooling issue persisted and was later traced to the evaporator. The vehicle has been inspected by the dealership (manufacturer-authorized) on multiple occasions for this A/C concern. No specific warning lamps or messages appeared on the dashboard related to the A/C system. This appears to be part of a broader pattern reported by owners of similar 2016-2021 Honda Civics, where condenser failures (sometimes covered by extended warranty) are followed by evaporator leaks, possibly related to the vehicle's use of R-1234yf refrigerant and system pressures. I recently received partial goodwill assistance from the manufacturer toward repair costs, but the issue highlights a recurring defect in the A/C system that affects cooling reliability. This car is driven by my 20 years old daughter as a commuter car to college and she is really suffering. I feel I am putting her at risk and need to get it fixed ASAP at whatever cost.
