Car threw a p0035 code which indicates a problem with the turbo bypass valve solenoid high voltage/circuit. Car suddenly lost power and had many service lights go off. The check engine light, power steering, brakes, stability, and other lights went on. This prevents my car from going over 40 MPH without feeling like the car is struggling to accelerate. The dealership couldn't reproduce or confirm the issue when I went in for service. The code will disappear and reappear after a few starts ups. I noticed that the 2017 type R has this recall but I'm noticing a lot of other owners having this issue as well.

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.

Headgasket problem Fuel injector Problem Head bolt problem Engine enters limb mode when cold start due to head gasket leak Misfire on multiple cylinders due to fuel injector failure.
Loss of power during drive. Hesitation while acceleration and check engine light on. Unable to accelerate. Fuel pump recall on other same generation models.
The contact owns a 2018 Honda Civic. The contact stated while driving at an undisclosed speed, the vehicle entered LIMP Mode and lost motive power. The contact was able to pull to the shoulder of the roadway, where the vehicle was able to be restarted. After restarting the vehicle, the vehicle returned to normal functionality, but the failure became a regular occurrence. The check engine warning light was illuminated. The vehicle was taken to an independent mechanic, who determined that there was a misfire in cylinder #3. The vehicle was not repaired. After investigating the failure, the contact related the failure to the federal safety agency Campaign Number: 23V858000 (Fuel System, Gasoline). The VIN was included, but parts were not yet available. The manufacturer was notified of the failure but provided no assistance. The failure mileage was 175,000.
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.
All dashboard warning light turn on flashing at the same time causing confusing and unsecured driving

Poor acceleration after stop, then twice again car loss power, I almost get into an accident due to this.
The engine light pops up on the dashboard stating an “emissions” issue. When scanned, it says that the fuel pump is malfunctioning.
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 the federal safety agency. 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.
Clutch failure resulting in a non-moveable vehicle in heavy traffic
Water leakage from the engine bay that damages coil packs and spark plugs. Coil pack seal is not durable enough to repel water once its introduce from the hood scoop.
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.
Ac system went out 3 times in less than 8 months
The A/C evaporator has apparently stopped working. The condensor had to be replaced because it was not manufactured to specifications, and a recall was generated. I am of the opinion that the same thing has happened to the evaporator, as this is a part that should not have failed.
Tl* the contact owns a 2018 honda civic. The contact stated that when driving at 45 MPH, the check engine warning light illuminated. The vehicle stalled and smoke emitted from under the hood.

10/16/2020 I was driving my 2018 honda civic lease vehicle with 20,099 miles still under honda bumper to bumper warranty. Car shut off while driving in the middle of the road without warning and will not start, it was tow in to honda dealer & as of todays date 1/23/2021 its still sitting at honda of downtown los angeles can not figured out and has honda case # 11791655 - un safe defective internal engine possibly and they do not want other consumer's to know
Since shortly after I got my car, brand new, it started to stall a little bit as I went to turn, if I had to stop or slow down beforehand. It got worse as time went on. I told honda before my first year was up and he told me to just take off eco. I did, but eventually it started doing that without eco. I'm afraid it's gonna do that when I have to turn left onto a busy road and not be able to get out of the way fast enough. Both eco and non eco should work efficiently. The date below is an estimate of when it started. It's been a couple years.
