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.

I got a new alternator because I thought it was draining the battery. A few weeks later I didn-??t drive my car for 3 days and the engine would not start but all the lights would turn on. I got it jumped and took it the dealership and they still don-??t know what is wrong with it. This is the 4th time this has happened and I changed the battery every time.

Every so often, quite a few lights will come on my dash. These lights include and relate to problems with power steering, hill start assist, emissions system, traction control tire pressure, and brake system. It does not allow me to use my brake hold when this happens. Also, unsure if it has anything to do with it, it has caused a problem with my first cylinder and is reading that the fuel system is too rich. But the original few lights that come on, will come and go randomly when the car is shut off overnight and will typically stay gone until the car sits with the parking break on for a few minutes.

Strong smell of fuel in the cabin due to known Honda oil dilution associated with the 1.5 turbo engine. Honda has a -??fix-?? for issue but states only cold weather states are affected. Our 2018 Honda Civic has had this issue for over 2 years now. Strong smell of fuel in the oil, along with oil above normal mark on dipstick. On oil change, oil is filled to the normal mark (3.7 quarts) and upon oil change, 4.5 quarts will come out (likely fuel in the oil). The major safety issue is that the smell of fuel in the cabin is strong to the point of causing driver and passengers to have burning eyes, and in some occasions, dizziness. No warning lights have come on as a result of this issue. Vehicle was taken to dealership over a year ago and dealership stated this is a problem in cold weather states and not in California. Dealership could not replicate issue.

Last July I had to have my AC condenser and compressor replaced due to one side of the air conditioner working. Bad part was i had to pay to have a recall fixed after the fact and now im trying to get American Honda to reimburse me my money. After 1 year the problem came back and now they are saying it's my evaporate coil. Honda is not taking this seriously and expecting people to pay several thousands of dollars to fix an issue that is their problem.

This car's evaporator is defective. Evaporator failure left many individuals, including myself, without air conditioning. In California, where I live, the temperature can rise above 100 degrees. Due to the leak and the high flammability of the freon, it is a safety risk. Additionally, drivers who must commute in hot weather may have dehydration due to the lack of air conditioning. Whenever i'm traveling the heat makes me feel weak and dizzy. Honda dealerships charge between $1,500 and $2,000 for repairs. I believe a recall should be issued to repair the entire A/C system in Honda vehicles from 2017 to 2019.

The contact owns a 2018 Honda Civic. The contact stated while driving approximately 20 MPH, several unknown warning lights illuminated and the vehicle started to idle very rough. The contact had taken the vehicle to a local dealer however, the vehicle was not diagnosed. The contact drove the vehicle to an independent mechanic who diagnosed that there was an engine cylinder misfire failure with DTC codes: P0302 and P0303. Additionally, the contact stated that there was a strong smell of gasoline in the cabin of the vehicle. The vehicle was not repaired. The manufacturer had been informed of the failure. The failure mileage was approximately 80,000. Fuel injectors were replaced by owner April 10, 2022. Upon oil change the same day, oil was very dark, despite only having 600 miles use since last changed and there was fuel noted in oil. Pictures were sent to NHTSA. Since changing injectors fuel mileage has improved greatly. The car has gone from averaging 37MPG to around 41MPG. Oil changed on 6/27/22, coloration was normal for routing change and did not note fuel in oil. No warning lights or issues with operation since injectors changed. The P0302 & P0303 codes were to be covered as part of a service bulletin relating to oil dilution but both Honda corp & dealership stated that injectors were not covered as part of the service bulletin. Even though the injectors could be directly responsible for the oil dilution issue if not properly functioning and throwing codes associated with the bulletin. Owner incurred the expense of rental car for a week, two lost days of onsite work with employer, and cost to purchase injectors. Will provide receipts.

There is fuel leaking into engine oil and thinning it out. My mechanic said there's a software issue causing it but a recall hasn't happened for it. It's hurting my car performance and making my car speed up faster even when breaking.

Driving on the highway and my check engine light starting to flash. I experienced loss of power and hesitation during acceleration. I got home and scanned my computer and it returned P0304. I then removed the #4 ignition coil and that's when I noticed rust. Seems like the seal on the ignition coil failed and water has been leaking into the #4 cylinder over time.

While driving at 50 mph on the right lane of the saw mill parkway the engine suddenly stopped running. The car came to a halt in the right lane. It was immovable. I put the flashers on, put the gear shift in park and pushed the start button. The car did start. I drove it home but am afraid to drive it again.
