general problems of the 2018 Honda Civic - part 1

I've had two 2018 Civics (first one was totaled) and the a/c issues are a serious hazard. The condenser and seal thankfully has been addressed with a recall, but after having had the condenser and seals replaced twice now (once on each car), my car is now experiencing evaporator failure :,) which makes my car stink :,) and I can't afford the repair at nearly twice my monthly rent :,) this of course is all happening during the anomalous, record-breaking 100+ degree heat waves in southern California. I suffered mild heat exhaustion driving home with the windows down while waiting to hear word back from Honda on whether or not they would accept my request for goodwill assistance, only to find that they initially denied it. I'm still trying to reopen my case with them, and I'd hate to have to sell the car for another, safer option. My whole family owns older model Hondas, and they have never experienced any "wear and tear" on their a/c systems. This is clearly a 2018 model design flaw and a serious safety issue that warrants investigation.

The ac system has failed. I took it to the dealership to have the condenser replaced, as Honda has extended the warranty on it due to the failure, but the evaporative core has also been affected and is leaking. Honda knows that this is a problem. There are many reports from other Civic owners that have had the same issue. Honda refuses to acknowledge this, and will not replace the condenser until the evaporative core is fixed. I am currently homeless, and live in my vehicle full time. I need my air conditioning to be working as the heat here is a safety risk. The problem has been confirmed by the dealership. The only symptom that occurred was the air conditioning was no longer blowing cold, and it occurred on February 24, 2026. I have contacted Honda and requested goodwill assistance, but they have refused to help in any way.

Windshield has a sudden crack after snow. I don’t know how it came to be.

Ac did not work at all when the outside temperature was hot. Service bulletin 19-091 performed. Ac blew cold after the repair. 1 year later ac did not work at all again. Dealership said the extended warranty will not cover it because it is an evaporator leak. This is a known issue and many have complained. If there is a leak in the evaporator then I would assume the refrigerant is leaking into the car and not outside the car. Risks of r1234yf refrigerant: flammability: r1234yf is classified as mildly flammable (a2l), meaning it requires a significant heat source to ignite but can burn. Toxic combustion products: when burned, r1234yf produces highly toxic and corrosive substances, such as hydrogen fluoride. Asphyxiation risk: a leak can displace oxygen, leading to a risk of asphyxiation in poorly ventilated areas. . Read more...

Ac evaporator leaking along with ac condenser and ac compressor confirmed by Honda dealership.

I have replaced my battery twice. I have purchased a new door handle so it wouldn’t drain the electric in my vehicle. I was told to drive my car every day to keep my battery charged. I just walked out the door and my battery is dead. This has happened approximately 12 times since I have owned this vehicle and I believe there should be a recall because you cannot find the parasitic draw. Please help me. I cannot afford all these repairs and this should be a recall. I have seen lots of articles about the 2018 Honda Civic sedan please file this under a recall.

I own a 2018 Honda Civic that is subject to an open fuel pump recall. My vehicle suddenly became completely inoperable. When attempting to start the car, all of the dashboard lights come on, but the engine will not start or crank. The vehicle has power but will not turn over at all. This failure happened without any prior warning. I contacted nalley Honda in union city, GA, and they confirmed that the issue is related to the fuel pump recall. However, they refused to provide towing for the vehicle and told me the earliest appointment available would be over a week out, despite the vehicle being undrivable due to this known safety defect. This situation puts my safety and my family’s safety at risk, as I am now stranded without reliable transportation because of a manufacturer defect. The problem has been acknowledged by the dealership but has not been resolved because of their refusal to assist with towing or provide a timely repair. There were no warning lights or error messages prior to the failure—this happened suddenly. I am requesting that the NHTSA investigate this issue further, as it presents a serious safety concern. I also want to report that Honda has not provided towing assistance or a loaner vehicle while the safety recall repair is pending, which leaves me without any transportation.

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.

Hello my name is [xxx] I sold this car to a buyer and would like to double remind the buyer about the recall so they can get it done, but they are not responding so I would like if you guys can remind them about the recall for safety measures thank you.

Honda recall the 2018 Civic for ac compressor shaft seal and the dealer repair the ac system 3 times and the problem was not fix. Also has a recall for a fuel pump motor but im not sure is was correct it for the old owner.

When I tried to open my gas tank on the neighborhood station to put gas it got locked and cannot be opened, the other drivers tried to help me and the station attendant. But to no avail I have to bring it to the local Honda dealership where I bought my car and it cost me almost $300. 00, the problem was there was no way it can be opened manually, one driver even tried to google it. Also, with this model, I received a recall notice about the fuel injection and tried to call the Honda dealer about the situation they always told me no parts available yet, but I am quiet scared because I don't want to get accident associated with the recall parts. The technician always said, "you are safe the car won't stop" but for how long? I also told them "how come they keep sending recall notice but every time I bring my car to the shop, they answered was "no available parts".

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.

The standard oem key fobs for Honda Civics, for several model years, and possibly for other Honda models, have a "feature" that seriously affects driver and passenger safety, and that cannot be disabled. If two buttons are depressed simultaneously on the key fob for a period of time, all of the windows go down and the doors unlock. I have encountered dozens and dozens, perhaps hundreds, of owner complaints about this "feature" on various internet bulletin boards. Typically, the stories go, "I parked downtown in an unsafe area and I came back to my car and found that it was unlocked with all of the windows open and someone stole everything from my car," or "I parked outside just before a rain storm and I returned to my car to find all of the windows open without my knowledge and the interior of my car was soaked. " single women could encounter this problem and be attacked by people hiding in the back seat. Apparently, if anything in one's pocket depresses the keys on the fob, without one's knowledge, this occurs. It has happened to me, where I'll bend down to tie my shoe and walk away and I'll return hours later to find all the windows open during a rain storm or in a bad part of town. I've asked american Honda numerous times for a way to disable this unwanted "feature" and they've said that they've not interested in addressing it unless they're forced to do so by the government. This is a serious safety issue, not only implicating potential crime, but a wet soaked car interior could affect electrical and navigation systems in a life-threatening way. If you respond, I can upload several internet pages with owner comments and complaints about this problem.

1) caused by faulty body control module (bcm). 2) can't enter car, key fob won't unlock car. Dashboard is illuminated when car is off, I can see it through my window. 3) alarm horn went on when car is off. 4) turn on my car, multiple errors, go to drive the car thinking I need to reset it from battery change. Shut off my car, but go to turn it back on. Car cranks but won't turn on, shows multiple errors on dash. 5) dash shows "keyless start system problem" and car won't turn off. When pushing button to turn off car, head lights and a/c turn off but the engine still runs, push/start button flashes. Disconnected battery, still runs. Had to pull fuel or ecu fuse to stop the car running. 6) can't reliably get my car to start. Issue is intermittent.

Stalling, oil pollution, electrical issues. The car shut off on me in the middle of the highway!.

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!.

My ac system in my 2018 Honda has now failed twice under 80000 miles. The first time the compressor and condenser were leaking and failed around 50000 miles which the dealership said was due to a new refrigerant that Honda had started using for this generation of Civics. Following this repair, Honda extended the warranty for these components of the ac system. Early in July 2024, I had the same issues with my ac blowing hot air only and making hissing and banging noises on the passenger side at around 75000 miles. Took this to the dealership and they again said that the compressor and condenser were leaking and had failed but also that the evaporator valve was leaking and failed due to the compressor and condenser issues. However, Honda has not extended their warranty for these parts and this would be an out of pocket cost. Honda needs to own up to their faulty ac system used in this generation of Honda Civics and extend the warranty to all involved parts or issue a recall and properly fix the system so it isn’t failing every 18 months.

Went to Honda dealership to diagnose why white smoke was coming through the ac vent whenever I would turn on the ac. Honda said that my ac condenser went bad, which is covered under the extended warranty due to others having the same issue but that my ac evaporator core was stain and also needs to be replaced. I was quoted $2322. 16 to have the evaporator replaced and it needed to be replaced before they could continue with replaced the condenser and recharged the system for free. Please help as it seems the issue has to do with the new freon Honda is using.

The electric power steering is bad in this model vehicle. Once the car is warmed up, it begins to have a stick/jerky steering wheel. It is difficult to make minor adjustments while driving straight, as the wheel jerks one way or the other when there is a problem. There is a recall on the eps on 2018 Honda Civics, however my VIN does not fall into the recall, and it should because it is a faulty part and is unsafe to drive. The sticky steering wheel will even show itself when in park. Steering should be smooth and this should not be an issue on a car with such low mileage. I have taken the vehicle to a certified Honda mechanic and they recommended replacing the eps rack. This should not be an issue on a car this new.

We have 2 Civics 2018 & 2019 both need ac evap core, had other parts replaced under warranty but this isn't covered and its $3000. 00.

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.

Infant mortality of the entire ac system due to faulty components. Cost of repair is $3000+. It is a common, systemic failure on this generation of Honda Civic. Lack of ac in hot regions can lead to unsafe mold growing in the vents as well as heat related illness potentially leading to death. This is a highly hazardous failure with a high likelihood of occurring, so it is unacceptable to allow this situation to continue without a full recall or reimbursement by Honda.

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.

Bumper loose, no a/c only for first day! car shakes at stop. Low power when pressing gas peddle.

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.

My vehicle will no longer start and after inspection from a mechanic, it was determined that the fuel pump was the cause. There was no indication of any issue besides not starting. I am now being told by my local dealership that they will not have replacement parts until the fall and they are unable to provide a loaner during this time, leaving me without a vehicle for an unknown amount of time.

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.

Faulty fuel door actuator. Replace fuel door actuator. And emergency latch within the trunk did not work. No way to open the fuel door to add gas.

The trms system constantly displays low tire pressure. I correct the tire pressure and reset the trms every time but it happens again and again. . The dealer has also reset the trms system, and in a few days it indicated that the tire pressure went down again. I have complained to the Honda dealerships and my mechanic. They’ve not found anything wrong. If the tires are good maybe there’s something wrong with the wheels. Although I have extensive receipts for all my maintenance and repairs, and I’ve frequently complained, they seldom indicate my complaints about tire pressure.

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.

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.

A/c problem.

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.

Paint job on this vehicle is awful 3+ yrs ago it started peeling and flaking off now there is no paint on my side mirrors contacted Honda just to be ignored.
