2020 Honda Civic UNKNOWN OR OTHER

I am the owner of a 2020 Honda Civic Sport, and my air conditioning system has stopped working due to a failed evaporator. A certified Honda dealer confirmed the diagnosis and quoted a high cost for repairs. After researching, I found many other Civic owners with the same issue across multiple model years (2016–2021). Honda has issued an extended warranty for the AC condenser but not for the evaporator, even though both are key components of the same system. This issue negatively impacts the comfort and safety of the vehicle, especially in hot climates, and appears to be widespread. I believe it warrants investigation and possibly a broader warranty extension or recall.

The A/C system failed due to contamination from the ac condenser and compressor shaft seal leaking. It was inspected at Hardin Honda dealership and confirmed these systems were leaking and the entire system was contaminated. My vehicle is available for inspection upon request. My safety is put at risk because the contamination can cause the engine to fail. The problem has been confirmed by Hardin Honda dealer and Honda issued two warranty extensions to fix these issues. Hardin Honda put in writing that the defect code is 6C300 and one of the two warranty extensions is under this code. Honda issued Service Bulletin 19-091 for my issue, but they are now refusing to stand behind their warranty extension. When we took it to the dealership they said our issue was not the same and that we had to pay thousands of dollars to fix the entire a/c system. The dealer said they cannot fix the two parts under warranty because the whole system is contaminated but the whole system is contaminated because of those two parts leaking. We reached out to Honda Corporation and they refuse to correlate our issue with the warranty extensions even though we have in writing from Hardin Honda that our A/C issues are the ones under the warranty. Honda issued these warranty extensions and are refusing to pay for the damages that my car is experiencing. The A/C system stopped working on 7/14/2025 and I took the car to the dealership on 7/17/2025 to get it checked out. Honda issued these warranties because of a manufacturing fail on their part and now they are refusing to fix their own issue and making us pay for damages that we had no idea were happening until our A/C system went out. If Honda had issued a recall for these faulty parts, then I would have taken my car in to be fixed right away and my whole a/c system would not be contaminated. We have been in communication with Honda Corp but they will not assist us and will not stand behind their warranty extensions.

I am writing to formally report a persistent and widely experienced issue with the air conditioning system on Honda Civic models from 2017 through 2025 (10th generation). Many owners, including myself, have encountered repeated failures where the A/C system either stops working entirely or begins to blow hot air. These issues appear to be linked to faulty components such as the condenser and evaporator, which have become known problems within the Civic community. I've also noticed that people will fix this issue, only to have it return a few years later. I got lucky when we purchased my car in 2020. We added a Honda Care package, which is still under warranty. They will replace everything without additional payment. What’s concerning is that once the vehicle is out of warranty, owners are being quoted anywhere from $1,300 to $3,000 for repairs, costs that seem excessive for a known defect affecting a major comfort and safety feature. I respectfully ask that Honda recognize this issue and provide appropriate support or reimbursement options for affected customers, especially considering the pattern and volume of complaints. Please let me know how Honda intends to address this concern and if there are any extended warranties or recall programs currently in place for the affected A/C components. Sincerely, [XXX] [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The evaporator in my 2020 Honda Civic failed without warning, causing the air conditioning system to stop blowing cold air. This posed a safety risk, especially in hot weather, as it affected driver comfort and increased the chance of fatigue or distraction. The issue was diagnosed and confirmed by a certified Honda dealership, whose staff acknowledged that evaporator failure is a common problem in 10th generation Civics and that Honda corporate is aware of multiple similar cases. While Honda has extended warranty coverage for other A/C components, the evaporator—despite its high failure rate—remains excluded. The repair is extremely labor-intensive and costly, often exceeding what many owners can reasonably afford, which discourages timely repairs. In many cases, the failure is due to leaking refrigerant, which not only compromises system performance but also poses an environmental hazard. There were no warning lights or messages before the failure, and the component is available for inspection upon request. I am requesting that Honda extend warranty coverage to include the evaporator and provide reimbursement for repairs due to the widespread nature, safety concerns, and environmental impact of this issue.

I am writing to formally express my concern regarding a malfunction with the fuel pump in my vehicle, 2020 Honda Civic. The fuel pump almost failed, leading to unknown issues with the vehicle's operation. I can provide access to the vehicle for inspection at your convenience. This malfunction almost put my safety and the safety of others at risk. The vehicle almost stalled unexpectedly while stationary, creating a hazardous situation. The issue has been confirmed by an independent service center, where they noted the possible fuel pump's failure as the primary cause of the problems I've experienced. The vehicle has not yet been inspected by the manufacturer but I am prepared to facilitate this immediately. Prior to the attempted failure, I noticed a few warning symptoms, including sporadic engine sputtering. These symptoms first occurred approximately yesterday October 14th, 2024 at 9:36am. I would appreciate your prompt attention to this matter and look forward to your response regarding the next steps to resolve this issue.

Vechicle was taken because the air blower was blowing hot. There is a recall the condenser on these cars but in addition the evaporator of the A/C equipement also has gone bad. They have said it needs to be replaced. The vechicel is still being paid for and its only has 38,593 miles. It definitely a manufacturing issue. They need to include this in their recalls.

There is a recall on my vehicle and I contacted Honda on April 1, 2024 to get the car repaired but was told there were no parts to repair the car. I tried to call back to schedule an appointment over 2 months later to remedy the recall but the dealership still does not have a solution or parts. This is unacceptable as it is unsafe to continue to drive the vehicle like this.

My fuel pump was causing some engine stalling and poor acceleration. It did not cause a breakdown but it could lead to flow disruptions of fuel, leading to potential breakdowns and costly repairs if not addressed promptly.

VIN [XXX] 2020 Honda Civic EXL 1.5 Sedan At approximately 49000 miles the air conditioning was checked and presented low in fluid. The system was refilled and the same problem reoccurred at approximately 52000 miles. On 12/29/2023 the vehicle was brought to be checked at Freeway Honda. The vehicle presents several different air conditioning leaks according to freeway Honda. It follows: A. Leak at A/C CONDENSER WA B. Leak at A/C COMPRESSOR SH C. Leak at EVAPORATOR. At one particular point, freeway Honda indicated that 2 of out of the 3 leaks would be covered under warranty. The particular freeway Honda dealer refused to fix the 2 A/C leaks unless if I would pay out of pocket the amount of $1,929.89+TAX to fix the 3rd leak as well. Furthermore, they charged me the amount of $175.00 to check for the leaks which should be under extended warranty. THE CAR HAS FACTORY A/C PROBLEMS PREVIOUSLY REPORTED BY THE HONDA AUTOMOBILE DIVISION. THERE ARE MORE PROBLEMS WHICH ALSO EXIST AND SHOULD BE TAKEN IN CONSIDERATION. I SHOULD NOT BE LIABLE FOR IT “A/C LEAKS”confirmed by Freeway Honda (714) 547-3555/ www.freewayhonda.com Service manager : Jamie Service advisor: Erick M.

PLEASE SE CASES 14345966, CASE 14345965 AND CASE 11565182.The report submitted verbally to NHTSA CASE 11565182 took place on 01/12/2023 at approximately 12:17pm. At one point, I requested from Ms. Lisa (NHTSA assistant) to read again back to me the particular report and she did. Consequently, I realized some miss interpretations. Therefore, I’m submitting this new information in order to be as accurate as possible. At approximately 49000 miles the air conditioning was checked and presented low in fluid. The system was refilled and the same problem reoccurred at approximately 52000 miles. On 12/29/2023 the vehicle was brought to be checked at Freeway Honda.

THE CAR HAS FACTORY A/C PROBLEMS PREVIOUSLY REPORTED BY THE HONDA AUTOMOBILE DIVISION. THERE ARE MORE PROBLEMS WHICH ALSO EXISTS AND IT SHOULD BE TAKEN UNDER CONSIDERATION. INITIALLY, HONDA STARTED EXTENDING WARRANTY FOR THE AIR CONDENSER. THEN, FOR THE COMPRESSOR. HOWEVER, THERE IS MUCH MORE. “The Civic AC systems are allegedly unable to withstand the pressures when circulating the R-1234yf coolant. Multiple air conditioning components allegedly cannot handle the pressure, including the condensers, compressors, evaporators and discharge and suction lines”. than the current used refrigerant, it is potentially dangerous as it is flammable and ignites 405 º C. When flammable- it also emits hydrogen fluoride- DANGEROUS SUBSTANCE FOR THE HUMAN HEALTH.

Yesterday I was driving my 2020 civic when my sunroof exploded spontaneously. I have dash cam(front and rear facing video) showing exactly what happened. No debris hit the car, no bumps were hit, and driving conditions were perfect. I know for a fact that this happened without any reason and I looked into it and there is currently a class action lawsuit with Honda about this problem. There is a problem in the manufacturing process that caused this and should be fixed.

Can turn engine off but goes into accessories mode and cannot be turned off. Drains battery. This has happened repeatedly. Only option is to disconnect battery every time after you drive and reconnect before starting. Also, navigation goes blank/black while driving.

In early October 2021, my inforainment display screen stooped working. As a consequence, my rear view, and right side view cameras no longer show on the display screen. This has become a safety issue for me because I cannot see if other vehicles are in the right lane when I am planning to change to the right lane, or planning to make a right turn. Also, I can no longer rely on my rear view camera when I am trying to back out of a parking spot, or my driveway. I took my car back to the dealer, and they told me that this HAS NOT been reported by other 2020 Honda Civic owners. They also told me that they need to order the part to repair it, but that it will take 2-6 weeks for the part to arrive. It has now been over 12 weeks and the part has not arrived. During the past 12 weeks, there were a few times where other drivers had to blow their horns at me as I tried to pass into the right lane. I have also had a few close encounters with pedestrians while I was backing out of a parking lot in shopping centers. Have any other 2020 Honda Civic owners reported problems with their infotainment display screens not working? Thank you
