Body Control Module The part was detected by Honda agency and they changed it because the battery was discharging. This Honda part already had problems with another model, but I don't want to admit that it also has them with the Civic models. The repair has a cost of $1000

I am the original owner. Had the compressor fail on year 4 (got it replaced)and now in year 6 the evaporator has failed. Dealer inspected and determined both. In Phoenix, AZ with heat advisories throughout the summer it’s not safe/healthy to be in the car exposed to such heat. It seems the entire A/C system is flawed but extended warranties only apply to condenser and compressor.

A/C went out on a road trip. Temperatures were in the 90s. No cold air. When it happened there was a really odd odor that we smelled that made us feel sick and nauseous. Took it to the dealer to look at it. They charged 360 just to look at it. Ended up replacing the condenser under warranty but that didn't fix the issue. Turns out it was the compressor that was the issue and not covered under warranty, Honda wants $1242 to repair the clutch, field and pulley assembly. With the number of complaints regarding the AC issues on these cars, there needs to be a recall or class action lawsuit to protect consumers. This is dangerous due to the smell and leaks and also due to no AC on hot days. My car has less than 60k miles and is a 2018, ridiculous!

I have noticed recently that almost every time when I start the car, it stalls for a second then turns on. There were many times that the car will jerk when I accelerate after being stopped at a red light. The car seems to not have as much power as before. I feel as though I have to step on the gas more to keep up speed especially on the freeway. Fortunately, no accidents have occurred. I have not had the vehicle inspected because when I called my local Honda dealership, they said they did not have the parts to replace it. There are no warning messages or lamps. I cannot pinpoint the exact date I have noticed these occurrences but most likely for a few months now since January 2024.

AC is not cooling. There was a recall last year (2023) for the A/C Compressor Shaft Seal Leak. I got it fixed by the Gardena dealership in California, but the issue has returned. When I turn on the A/C it makes an odd noise almost like a hissing noise. I no longer turn it on.

AC leaking Freon inside cabin. AC unit leaking Freon in atmosphere. My car’s AC unit started blowing hot air instead on AC cold air. Making it dangerous to stay and operate the vehicle while high temperatures here in California. I was told at Honda dealer that there are several TSB for AC repairs due to leaking from the AC condensers and AC compressor but that my car is leaking from inside the cabin through the evaporator and possibly inhaled the Freon that was escaped and the rest into the atmosphere. Extremely dangerous. Many articles about this please help? Honda USA is not helping fix and wants to do outrageous changes to get it fix.

My AC system completely failed in my 2018 Honda Civic. I took my vehicle into to service and I was informed that all 3 major components of the AC system is leaking refrigerant. The main problem being the Evaporator has been leaking refrigerant into the car cabin. I have gotten spells of lightheadedness and the feeling that I will pass out and I believe the refrigerant leaking into the cabin is to blame. Honda is aware of the compressor and condenser and evaporator being prone to leaking but will only repair the compressor and condenser free of charge but not the evaporator. Honda is knows the evaporator is defective but does not want to admit it.

Went in to a certified Honda Dealership because my car that is only 7 years old had an AC that doesn't work. After the diagnostic they said 3 parts were faulty but only 2 were under warranty. To fix all three and fully fix the system it would cost $2200. I live in Minnesota, I don't even use the AC half of the year and it's still broken? Evaporators are supposed to last 10+ years, and with the winters here thats around 4 years of using the AC and all three of those parts broke. I did not get the repair because I'm hoping it will also be recalled, obviously there was serious issues with the AC in the original model and that's why 2 of the major components were already under extended warranty.

the evaporator of the AC system failed at 48k miles. We live in Houston Texas and AC is not a luxury it's a requirement making the vehicle unsafe to drive in the extreme temperatures. Honda knows that this is an issue and has recalled both the condenser and compressor of the AC system to a ten year warranty. We're asking that the evaporator also be added to the recall. The cost of repair of the item is almost 1700 US dollars. It's a terrible situation. As the car is like new but out of manufacturers warranty being left with a ridiculous repair cost on a part that should last for the lifetime of the vehicle. I have a Toyota that is 13 years old and never had any issues with the AC system. Thank you.

Unknown. I arrived to the grocery store and went inside to shop. About 45 minutes later I approached my vehicle and attempted to remote start it. As I approached my vehicle I saw it was on (assuming it was from my remote start). My car wouldn’t unlock. The trunk also wouldn’t unlock. My key fob was not dead as I went back into the grocery store and bought a new battery and replaced it. After that still did not work, I attempted to open my car door with the manual key included in my key fob. The manual key also wouldn’t work. At this point I realized my car was not on due to remote start. My car was actually running the entire time. I was stranded for 5 hours while I had to wait for my fiancé to leave work and travel to the part of town I was on. He was also unsuccessful with using the key. We had to resort to unlocking the door with a wire hanger by sticking it through the door. After we successfully unlocked the door, the car alarm went off and the key was working like nothing ever happened. I also want to mention we went home yo get my spare and the spare wasn’t working. How were all doors locked while the car was completely running. It burned a quarter tank of gas. I just wanted to make this report to note what happened.

Air conditioner continues to fail and break. I am going back to Honda to fix this issue and I will then have my 4th condenser put in this car. I have a baby on the way and my car has been paid off. Now I'll have to sell this car and get something different so I can actually have air conditioning that works. It was replaced 4 months ago and already I need a new condenser. It's a 2018 civic si so not even a old car by any means. Only 73k miles. Honda keeps replacing it with the recalled parts and it just happens over and over again. Shouldn't have to make a appointment every 4 months to fix the same issue over and over.

I purchased a 2018 Civic that is showing severe paint failure around the mirrors and doors of the vehicle. This is an extremely common manufacturing defect that is documented through formal cases opened with Honda, consumer reports, news reports, and dealership inquiries. Severely flaking paint can cause blind spots and vision problems due to sun reactions to exposed metal, driving distractions as paint chips fly off vehicle, environmental pollution, and damage to critical components through rust and water damage.

Air conditioning not blowing cold air. Took vehicle to Honda dealer. I was told that A/C will need to be recharged with Freon and dye, the cost is $299.95 Once recharged, the A/C will need to be re inspected for further leaks in the A/C system. The A/C compressor seal shaft and the A/C condenser, these two parts, the warranty has been extended by Honda. The A/C evaporator is not covered by Honda warranty. It is a well documented fact that Honda’s A/C systems on the 2018 Civic has defective components. It appears that the R1234yf refrigerant used in these systems is deteriorating the A/C components. Honda has responded to this situation by extending the warranty on the condenser and compressor seal shaft to 10 years from date of purchase. However, to date they have refused to extend the warranty on the evaporator and other components of the system. Typically, evaporator last the lifetime of a vehicle, or at least 10 to 15 years. It is unfair for Honda to charge $299.95 to inspect a system that is known to be faulty, and to saddle the customer with another $2200.00 if the evaporator is found to be leaking. The entire A/C system should be covered by the 10 year extended warranty. Because if the system is functioning as it should, there would be no leaks, and therefore no need to recharge with Freon and dye.

I have an 2018 Honda Civic, twice now, my AC has stopped working. The first time Honda warrantied the compressor and now 2 years later, I'm having the same issue. I bought a Honda so I wouldn't have to worry about this kind of stuff. I'm going back to the Nissan

The AC has failed 3 times on my car. I have had the car since 2017 (73,000 miles) and today marks my 3rd time taking the car in for an AC issue (blowing warm, unable to cool cabin). This has been frustrating since Honda has been known to be reliable. It is very unfortunate that they cannot place a recall on this car due it it lacking a "safety" issue. I live in Southern California and during the summer, I definitely consider not having AC a safety issue. Taking my car to the dealer is inconvenient and takes away from my life. Not only does dealer not have loaner cars until the issue is considered a warranty, but I have to take Personal Time Off so that I can take care of this manufacture problem.

Safety hazard for vehicles in the State of Florida. Honda Civic 2016-2018 models defective/failing AC system. Common failing Components include Condenser, Compressor and Evaporator. I paid for a new car and within the first few years of purchase the ac went out due to Honda’s faulty equipment. Per Dealer recommendation replacing evaporator with expansion valve. $2200 to repair. This is a safety concern and hazard in the State of Florida. Health reasons include being exposed to Floridas heat for long periods of time. And with Florida’s unpredictable weather conditions and rainfall, when it rains all windows including windshield fogs up which creates the inability to see which effects the driver and surrounding motorists. Honda has acknowledged the issue but only extended its warranty on the Condenser and Compressor. Not the evaporator. Which SpaceCoast Honda has stated they see more commonly the evaporator failing above all else.
