2018 Honda Civic

My vehicles evaporator is leaking and needs to be fully replaced along with the condenser. I replaced the condenser less than two years ago. My car has less than 50,000 miles. There are thousands of complaints of Honda owners with this same issue and Honda refuses to cover the cost and extend the warranty when it is a known issue. The faulty condenser is causing the evaporator to fail as well. Honda needs to take responsibility for this design flaw. It is very dangerous in these heat waves to drive without AC. Honda is refusing goodwill assistance for me and hundreds of thousands of others.

On August 11, 2026, AutoNation Honda Lewisville confirmed that my A/C Condenser and Compressor Shaft Seal failed and required replacement under Honda’s extended warranty (Extension 6A5). However, they identified that the evaporator core—a component within the exact same pressurized loop—failed concurrently due to pipe corrosion, contamination, and pressure imbalances caused by the acknowledged defective parts. AC for this vehicle is already having 10 years for 2 problems condenser seal and compressor shaft seal was leaking. But this issue caused the evaporator core to corrode and hence evaporator core had to be replaced. Honda dealer charges 2600 dollars for this repair. Please open a recall for entire AC system and do not let go Honda unaccountable for such a huge problem with this 10th generation civic. Please have them cove the evaporator core in the AC warranty that is extended for 10 years. Vehicle is a safety hazard to be driven in 110 F heat and is dangerous with AC system fails, there is no other option but to repair such and issue and customer has to foot the bill of 2600 dollars. Please help.

The air conditioner on this car has broken 8 times since 2020 and it will not defog the car when it does not work. The car also gets dangerously hot. Honda will not admit to faulty parts that repeatedly fail. 8/25/26 evaporator core replacement Expansion valve and AC conditioner pipe 6/8/26 - replaced Compressor shaft leaking & replaced 4/10/26 Condenser replace 6/10/25 - 8/8/24 compressor o rings and shaft seal Condenser replace 5/2/24 7/19/23 replaced compressor seal and condenser replaced 2/3/22 compressor replaced 9/10/20 condenser replaced

This is a 2018 Honda Civic with only 30,000 miles on it. The a/c system has now broken down for the 7th time. I am [XXX] old this has caused me to be stranded and has also caused me to become dizzy, nauseous and have blurry vision because I cannot tolerate the summer heat without air conditioning. I have tried to have it repaired 7 times & the dealership even though Honda has "warrantied" it has also forced me to pay over $1400 for a faulty system they never actually fix. It is absolutely a safety hazard for me and also elder abuse. I have ALL the invoices but it's too many to send. I can send the 3 from the FIRST year it started. But it's happened EVERY SUMMER since!

AC system has engineering problem. It uses new regfirgirant type and it corrodes the shaft seal and the compressor and also the Evaporator core. Honda has an extended warranty on shaft seal and the compressor leak but not on Evaporator. But overall system is an issue. My shaft seal and the compressor were replaced under the extended warranty in 2024 but again the same thing happend and now Evaporator core is also needing the replacement. The cost of that part replacement is close to 2600 dollars. This is a theft and you should hold Honda responsible for this faulty Ac system and its engineering.

Evaporator failure in Honda Civic 2018, causing upwards of $2,000 for repair. This is a major safety issue that in extreme heat (such as california weather) can cause driver fatigue, and electrical failure from overheating as well. I personally was not covered under the Honda extended warranty for the condenser seal replacement because my evaporator was also not working. Especially as someone who is working in my car most of the time, driving between facilities, I need to have functioning air conditioning for my own safety. Multiple times now I have experienced nausea and fatigue while driving, with no remedy other than parking at a store and sitting in the AC until I could cool off. This is not right, and Honda is not being helpful with solving this issue that should be covered. I first discovered this in early 2025, got it fixed through an extended warranty, and now my AC has failed again because of the evaporator failure. No warning lights, problem has been confirmed by a dealer.

Honda refused to cover failed AC evaporator under extended warranty or goodwill warranty. They cover the compressor and condenser but not the evaporator. This is the 4th time my AC has gone out on my 2018 Civic. There is a film on the inside of my windshield and I am also concerned about what I may have been breathing in while the AC is on. I have read that issues with your condenser can cause issues with your evaporator. I don't understand why the evaporator isn't covered. I have all the receipts from the prior repairs.

On 07/08/2026, the Infotainment system on my 2018 Honda Civic EX failed throughout the entire day into the morning of 07/09/2026. The screen became pixelated and would then turn black, not allowing me to see the screen at all. No matter how many times I attempted to reboot the unit or restart the vehicle, the issue did not resolve. Although this is not an urgent safety issue since it is related to the radio unit, this screen does display other components that are critically related to safety, such as the backup camera and passenger’s side blind spot camera. While being unable to see the screen, these added safety features are not available to the driver because they are not functional. Being that the vehicle is not equipped with backup/blind spot sensors as most other modern vehicles are, a driver would be dependent on these cameras to avoid a crash. I then serviced the vehicle at Planet Honda on Route 22 in Union, New Jersey, where the technicians completed a full diagnostic inspection. After running several electrical codes, technicians found no mechanical/electrical issue with my vehicle that would cause the system to fail. The service advisor stated that this is a common issue among many Honda owners and the issue lies within the system itself. Unfortunately the only fix would be to replace the entire unit totaling almost $2,700.00. If this is a common issue with other Honda vehicles, why has Honda not addressed this? My brother also owns a CRV and has noted that he has similar issues with his display. The entertainment system of the vehicle contains everything related to the vehicle, between camera views, settings, etc. If it is failing for many Honda owners and the only remedy is an expensive replacement, Honda should be held responsible. I cannot afford to pay almost $3,000.00 for something so essential.

1. Component/System: HVAC evaporator core. Total loss of climate control. Vehicle is a 2018 model. Prior to this, it had the known AC condenser defect covered under TSB 19-091. The condenser was repaired under warranty, but the AC loop continued to have underlying issues. Failed evaporator available for inspection. For the 2018 Honda Civic specifically, there are over 600+ total consumer complaints filed with the NHTSA, and the overwhelming majority are dedicated exclusively to the failing air conditioning system. 2. Safety Risk: Immediate safety hazard from extreme environmental exposure. In regional desert temperatures exceeding 115°F-118°F, the complete loss of cabin cooling creates a severe risk of heat exhaustion, dehydration, and heat-induced physical impairment for the driver while operating the vehicle on public roads. Additionally, during high humidity, the system emits a chemical-smelling mist/vapor from the vents causing an acute burning sensation in the driver’s eyes. 3. Reproduced/Confirmed: Yes. Right Honda (Scottsdale, AZ) inspected the vehicle and confirmed the evaporator leak on 07/11/2025. I have also observed the chemical mist/vapor emission, which was corroborated by a witness while driving in California. 4. Inspected by Others: Reviewed by Right Honda service department. Escalated to American Honda Motor Co., Inc. (Case #16391364). Despite 5 years of ownership and previous failures in the same AC loop, the manufacturer refuses to cover the repair of this systemic defect. 5. Warning Lamps/Symptoms: No dashboard warning lamps. Initial symptoms began at ~59,857 miles with a gradual decline in AC performance, degrading to total loss of cooling at idle. Most recently, during high humidity, the system began emitting a chemical-smelling mist from the air vents, which causes a burning sensation in the eyes upon contact.
