2020 Honda Civic Problems

While I was crossing the street on [XXX] coming down from [XXX] there was a white Honda with the license plate number [XXX] with a male driver by the name of [XXX] and a Mexican light skinned female passenger driving making an illegal left turn without a blinker and hit me with their car and I fell down on my right knee dropping all of my belongings and they drove away and returned a couple minutes later and left then returned again but stopping next to me at the stop sign on [XXX] and the passenger was laughing while looking at me and they made a right turn down [XXX] and I called the police and they came within 2 minutes. It was 2 male officers one Mexican and the other white and I reported them for police misconduct because of their discrimination against me verbally calling me fat, ugly and saying I smell. They also didn’t file a police report and claimed I didn’t meet criteria which isn’t true because my right knee and left calf are bruised and swollen and I have memory loss as well as emotional stress.

The headlight electrical wiring on my 2020 Honda Civic Sport sedan, which has 97,000 miles, has experienced deterioration, with the wire insulation disintegrating on one headlight. The Honda dealership inspected the vehicle and confirmed that the wiring insulation is breaking down naturally, not as a result of rodent damage or outside interference. The damaged wiring and headlight connector is available for inspection upon request. This creates a potential safety hazard because deteriorating wire insulation and the blown connector can expose electrical conductors, cause electrical shorts, interrupt headlight operation, and potentially create a fire risk. Headlights are critical for nighttime visibility and ensuring other drivers can see my vehicle, so any loss of headlight function could put me and other motorists at risk. The problem was confirmed by an authorized Honda dealership, which provided an estimated repair cost of approximately $360. The vehicle has been inspected by Honda dealership personnel, who identified the deteriorating wiring and blown connector, recommended repair. There were no known warning lights or dashboard messages before the issue was discovered or after. I was unaware of the deterioration until the dealership inspected the vehicle and brought the problem to my attention. I am concerned that the blown connector and wiring insulation is disintegrating prematurely on a relatively recent model-year vehicle and believe this could be a broader manufacturing or material defect that may affect other Honda Civic owners.

The wheel becomes sticky/ jerky when driving at speeds over 40 mph and causes overcorrecting. It is worse around bends and makes holding the wheel straight difficult. The stickness is consistently present when on the highways making it incredibly dangerous to drive at these higher speeds as I am constantly having to overcorrect the wheel. The dealer and an independent service center have both said they have been able to reproduce the sticky steering and that it is the steering rack. There is not any warning on my dashboard to indicate this part is failing which is also problematic as I should be made aware before my steering wheel completely freezes when driving at high speeds.

My car 2020 honda civic has an issue with the steering wheel. I have noticed in the past 6 months that the steering wheel has become increasingly stiff and gets stuck during turns. This is a concern of mine because at times it becomes difficult to keep in traffic lanes. The car has not been inspected by anyone.

My 2020 Honda Civic Sport Hatchback, 1.5L turbo, 6-speed manual, has experienced repeat premature clutch-system failure. The original clutch/flywheel assembly failed at about 34,000 miles. Honda repaired it under TSB 22-017, which addresses supplier production issues causing premature friction-disc wear. Honda advised that updated components were installed. Significant clutch slipping began again in early June 2026. At about 61,500 total miles, only about 27,500 miles after the first repair, transmission removal and clutch-component replacement were required. The onset date entered is approximate. The dealer documented: "Clutch shows sign of Heat Buildup on flywheel and pressure plate with debris inside bellhousing on release bearing. Recommend replacing Pressure plate, Friction Disc, and release bearing." Inspection photos show substantial heat discoloration of the pressure plate/flywheel and heat/glazing of the friction disc. The servicing Honda dealer did not identify driver abuse or improper clutch operation as the cause. No significant fluid contamination or catastrophic transmission damage was identified to me. I have substantial manual-transmission driving experience without comparable repeated failures. Clutch slipping allows RPM to rise without corresponding acceleration, creating a potential unexpected inability to accelerate when merging, entering traffic, crossing intersections or climbing grades. Honda classified this as out-of-warranty wear and tear. I request that NHTSA retain and compare this repeat premature failure, including failure of Honda's updated replacement, with other Civic manual-transmission complaints. Repair orders, photos, mileage documentation and the TSB can be provided upon request.

I own a 2020 Civic Si. At about 29,000 the clutch started slipping in higher heats and going up hills. Once I noticed this the clutch degraded very quickly to the point it was unsafe to drive. By very quickly I mean in about 100 miles worth of travel. I notified Honda Corporate and opened a case with them. There is a TSB 22-017 out about the faulty clutches stating the friction material was faulty in some 19-20 models and to replace the clutch and included all parts associated to be replaced. However my car was just one year outside of the warranty even tho it was within the mileage. Since they were going to replace with the same parts that failed, I decided to do the replacement myself with an OEM clutch made for the Type R which is more appropriately matched to the torque of the vehicle and a different flywheel as the factory one increases the wear due to being dual mass. I took pictures of the process for documentation. When the transmission was opened up the friction material had basically disintegrated into chuncks. The pressure plate also seemed to be putting unnecessary amount of pressure on the bearing. Almost like the clamping force was far too much for the hydrolic system to counter and thus caused excessive slippage. Honda was going to charge $2000 to diagnose the clutch and the clutch replacement would have cost $6,000. That is an absurd amount to charge for a known faulty part. Tho the new clutch also required an upgraded CMC, I was about to install a far superior OEM part for 1/3 of the price. I wanted to submit a report in hopes that with enough complaints Honda will do a proper recall before someone in the future loses function of their clutch and potentially has an accident.

On 04/2025 the car was driving fine with no warnings or indication of a problem. Turned my car on at a parking lot and as I was driving away the car suddenly stopped, all the warning lights started coming on. I was able to turn it back on and drove it to a nearby dealer. I am the second owner of the car and Honda dealer said the fuel pump had already been replaced due to a recall. This time they said it was a secondary fuel pump that was the problem and the very expensive repair was done. Fast forward to 2/2026 and the same thing happened. This time it was scarier as it shut off as a car was backing up from a parking spot. Fortunately, the driver saw the car and was able to stop before running into me. The car failed to start, and I had to get it towed. Could not tow it to the dealer since it was late in the evening. The next morning, the car did start, but all the warnings continued to flash on the dash. The car is being towed to the dealer where the "repair" was done. All this happening within a year of repairs. This should be a recall and Honda should refund my initial repairs as this is happening to other drivers as well.

Fuel pump issue. There is an active recall for this make and model but this vin isn’t included. The car will be fine and either completely shut down or once parked it won’t restart. After about an hour it will start and be fine. We took to a local mechanic who diagnosed the fuel pump. Said there was a recall so we went to the local dealership. They said it isn’t included and they can’t get the fuel pumps as they are being held for recalls only. The car continues to have this issue which is unsafe. I’ve contacted Honda corporate who are trying to get a fuel pump for us. We believe this should be included in the recall and should be looked into further I’m listing the most recent incident date but it’s happened at least 20 times since August 2025

on 7-28-26 After filling my vehicle with gas at the next red light, all lights on dashboard went on flickering warning (Christmas tree effect). on 7-29-26 After researching online Roadside came out and did Battery and alternator test that passed. I did hard reboot from instructions I found online and after several attempts the lights cleared twice, the morning of 7-30-26 when leaving for work the flickering lights came back on. Vehicle had a slight tremble but cleared after a few seconds while vehicle warmed up. I went to get the battery checked at the shop and it passed also had air filter changed. Lights still on, car is running fine, but I feel unsafe to drive and have an appt at the dealer for a diagnosis check on 7-31-26.

The contact owns a 2020 Honda Civic. The contact stated that while driving 60 MPH, a bobcat crossed the road, and the bobcat was struck by the vehicle. The contact stated that there was extensive front-end damage and undercarriage damage to the vehicle. The driver’s and passenger’s side air bags did not deploy. The contact was unsure whether there was a warning light illuminated. The contact was not injured. The vehicle was driven to a gas station, inspected, and then driven back to the residence. However, the vehicle failed to accelerate above 40 MPH. The vehicle was taken to a collision center for repair. The contact received a call from the collision center and was informed that all the air bags in the vehicle had been removed and that the wires were cut and twisted together, which led the sensors to believe the air bags were still connected. The vehicle was not repaired due to the cost. The manufacturer was not notified of the failure. The failure mileage was approximately 78,000.

The contact owns a 2020 Honda Civic. The contact received notification of NHTSA Campaign Number: 24V064000 (AIR BAGS). The vehicle was taken to the dealer for the recall repairs, and the contact was informed that the part to do the recall repair was not yet available. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The manufacturer was not made aware of the issue. The contact had not experienced a failure.

My automatic Breaks that prevents me from rear ending a car keeps engaging when I am a few car lengths from another vehicle. It’s happened once yesterday and once today. Both times in heavy traffic areas. I’ve had the car for two years and this is the first time this has happened. Thankfully no one was following close behind because they may have hit me. I’m afraid this is going to happen one day when someone is too close and I’m going to get rear ended. It’s really scary and dangerous. I’m scared to drive my car.

Very frequently, the brake alert system comes on while on the highway causing my vehicle to engage the braking system. This happens whether or not there is a vehicle in front of me.

REPEATED A/C SYSTEM FAILURES – DEFECTIVE EVAPORATOR, RECURRING WINDSHIELD FOGGING, AND IMPAIRED DRIVER VISIBILITY My 2020 Honda Civic LX has experienced three separate air-conditioning system failures in approximately two years of ownership. Previous repairs involved the A/C condenser and compressor. On October 16, 2026, Chula Vista Honda diagnosed another refrigerant leak, this time involving the A/C evaporator. These repeated failures raise serious concerns about the reliability of the vehicle’s air-conditioning system and its role in maintaining adequate windshield visibility during normal driving conditions. Since the latest A/C failure, I have experienced recurring windshield and window fogging while driving. The problem is particularly concerning because the air-conditioning system assists with removing moisture from the cabin air, helping the windshield defogging system clear condensation from the glass. When the A/C system loses refrigerant and stops functioning properly, its ability to dehumidify the air may be reduced, potentially making windshield fogging more difficult to control under certain weather conditions. These fogging episodes have occurred on multiple occasions since the latest A/C failure. I am concerned about the potential for reduced forward and side-window visibility, particularly during cooler temperatures, humid conditions, and periods when condensation develops on the glass. Windshield fogging presents a serious safety concern because it can interfere with a driver’s ability to identify pedestrians, cyclists, surrounding vehicles, traffic signals, and road hazards. Temporary obstruction of the windshield at highway speeds or while approaching intersections can increase the risk of a collision. Honda’s vehicle operating instructions recognize the role of air conditioning in assisting with windshield defogging. A refrigerant leak that disables the A/C system can reduce its moisture-removal capability and may compromise effective win

The air conditioning condenser failed prematurely due to a known manufacturing defect covered under Honda's 10-year warranty extension (TSB 19-091), but the dealership, Stokes Honda North and American Honda Motor Co.’s refused to honor the coverage. I reside in Charleston, South Carolina, where summer temperatures and humidity levels are extreme. Because of this defect, the vehicle's cabin becomes dangerously hot within minutes. I frequently transport my two young children in this vehicle, and the lack of functional climate control places them at an immediate risk for severe heat exhaustion, dehydration, and heat-related illness. Furthermore, the failure of the AC system means the vehicle can no longer properly dehumidify the cabin air. During sudden South Carolina rainstorms, the windshield and windows instantly fog over, rendering the defroster useless. This causes an immediate, severe loss of visibility while driving on high-speed roads, creating a catastrophic safety hazard for myself, my children, and other drivers.

My 2020 Honda Civic experienced engine overheating and a cylinder 3 misfire (P0303). Two independent mechanics diagnosed a blown head gasket with coolant leaking into cylinder 3. The vehicle underwent a head gasket repair under Honda’s extended warranty. Less than a week after the repair, the engine overheated again while I was driving. I pulled over, waited approximately an hour for the engine to cool, added coolant, and drove to the dealership. The dealership later reported that the cylinder head was cracked near cylinder 4, close to the exhaust valve. When I picked my car up from the dealership, I scanned the vehicle and found the P0303 cylinder 3 misfire code. I am concerned that the engine may have an unresolved problem that could cause it to overheat again, sustain further damage, or lose power while driving. The vehicle is still in my possession and available for inspection. I have an appointment with an independent mechanic on October 24, 2026, to have the engine and cooling system inspected and determine what may have caused the repeated overheating. I am submitting this complaint to bring attention to a potential engine or engine-cooling safety defect and ask NHTSA to consider whether similar problems may be affecting other vehicles.

The turbocharger bypass control solenoid valve circuit on my 2020 Civic Si has developed an intermittent open, setting DTC P0035. I diagnosed it myself: the solenoid coil measures 45 ohms and functions when commanded via bi-directional scan tool, and supply voltage is present at the harness connector. However, the control circuit reads approximately 9V in the off state when it should be near ground, and the reading fluctuates when the harness is flexed near the connector — indicating a partial break in the wiring consistent with vibration fatigue. This is a safety concern because the ECM fault cascades to other systems. My scan report shows U0401-68 in the ABS module and U0416-68 in both the EPS and Integrated Driver Assistance modules. The result is that VSA stability control is disabled. I first noticed the problem because warning lights appear during hard cornering — precisely when stability control is most needed. Honda has acknowledged this exact failure mode. Service Bulletin 18-044 (NHTSA ID 10142655), issued June 2018, covers the 2017 Civic Type R for DTC P0035 and states the cause as: heat and the natural frequency of the harness cause the coupler wire to oscillate, producing an open circuit to the turbocharger bypass control solenoid valve. The remedy was a replacement engine wire harness kit. The Si shares the same L15B7 engine family and the same bypass control solenoid circuit, but no campaign covers it. Owner forums document numerous P0035 wiring failures on non-Type-R 1.5T Civics. I am requesting that NHTSA consider whether this defect and its effect on stability control warrants a safety investigation and expansion of the existing remedy to other 1.5T Civic models.

On passenger side, 4 of 5 wheel hub bolts (lug bolts) broke off during driving. The lug nuts did not come loose. The bolts actually broke off with lug nuts attached. This caused the wheel to separate from the car while driving. This caused an accident and $5,500 damage to the car. There were no warnings from the in-car information center.

The contact owns a 2020 Honda Civic. While driving 50 MPH on the highway, the passenger’s side wheel felt as if the wheel was about to detach, causing the vehicle to veer to the right. The vehicle returned to normal functionality and operated as designed. No warning light was illuminated. The vehicle was not diagnosed or repaired. The manufacturer was not notified of the failure. The contact related the failure to NHTSA Campaign Number: 25E071000 (Wheels). The approximate failure mileage was 63,000.

I was driving to work in the rain on the highway and I heard a big thump and I thought I had hit something and my wheel went sideways and I kept trying to keep my car on the road even though I didn’t hit anything.

my car has been grinding ever since I purchased the car. The vehicle only had 17,000 miles when I bought it. I took it to Honda of Hollywood and let them know that my car was grinding and they said that I needed to change my brakes. I changed my brakes and went back to the dealership and they said I needed to sand the rotors. I went to get my rotors repaired and my car was still grinding. I went back to the dealership and they said nothing was wrong with the car. I don't hear any other Honda grinding like my car. On the freeway my car is rattling. The tires in the back of my car move around they are not straight. I looked under my car and noticed that the wheel bearing is broken. I don't think the dealership should be putting my life in jeopardy like that when my car was under warranty when I reported the issue.i need help.

I reported this issue to insurance. The facts are that when I was watching a family member’s toddler, I went to my vehicle to grab a stack of papers. While holding her, I reached in and grabbed the papers sitting directly on the back seat of the coupe vehicle (I.e., easy to reach). Upon grabbing the papers in one hand and holding her on my left hip, I shut the drivers side door and began walking toward the home. Immediately, I heard an odd sound like a rustle or possibly an animal scurrying. I looked around confused because I hadn’t seen anything and it wasn’t too dark. Then I looked closer and the entirety of my back windshield was shattered into a billion pieces leaking into my back seats and onto the car seat placed there for when I frequently pick up the toddler. I can’t help but think of what would’ve happened if she was in her car seat and the glass shards (which were many, sharp and permeating through each crevice and likely will remain until somehow discovered or hurting someone) would’ve fell there. Many honda owners experienced this issue of combustion in the rear windshield. It’s not safe or right. A recall should be made.

I bought this car from a Honda dealership in Cincinnati. I searched for this specific year and color. It had about 48k miles on it when I got it. I have only put on 14k miles now. I purchased the warranty. After a year of owning it. My paint on the plastic pieces started to chip off. The mirror is nearly completely paintless, and the door handles look bad as well. I have been trying to work with Honda. The dealership recognized this was an issue with this color. There is a class action for the white as well. The honda dealership said Honda corporate should do something about it since I haven't had this car very long. Honda corporate came back and told me that they would have only covered it in the year of 2020 which is silly because the car is a 2020. I purchased it at the end of 2023. So as soon as I got this off of the lot I was [XXX] essentially. I told them that I haven't even put that many miles on the car and they said it didn't matter. Online everywhere talks about the issues with the paint chipping on the plastics and they refuse to recognize it. I was quoted over 1000 to fix the more serious issues but another 400 more to fix everything and that was just for the parts and not the labor. The dealership service manager at Honda recognized this was a problem but corporate doesn't want to do anything about it. The issue started happening a year after I purchased it. I haven't even owned it for a full two years. Not even 14k miles on it since my purchase. Purchased the warranty and they refuse to help.

The contact owns a 2020 Honda Civic. The contact stated that the front driver’s side door failed to open as needed. The contact stated that several attempts were needed to open the door. After investigating the failure, the contact related the failure to the steel beams inside the door. The contact stated that the failure occurred frequently. The contact had suffered rotator cuff injuries on both shoulders. The vehicle was not diagnosed or repaired. The manufacturer was notified of the failure but referred the contact to the NHTSA Hotline for assistance. The failure mileage was approximately 25,000.

I financed this car 3 months ago, and I received a safety recall notice from Honda. Unfortunately, they don't have the necessary part until 2025. As a result, I've been unable to rent out the car on Toro for the past 2 months to make finance payments. Additionally, due to a previous car accident, I don't feel safe driving the car, which causes me anxiety. Now, I'm unsure what steps to take. I want to return the car without negatively impacting my credit score, as this situation is not my fault. I'm losing both money and payments because of the recall, and the car can't be fixed until 2025.

The contact owned a 2020 Honda Civic equipped with Continental tires, Tire line: Conti Pro Contact, Tire size: 235/40/R18, and DOT number: af2rwd3w. The contact stated while driving at 75 MPH, the rear passenger side tire blew out suddenly which the vehicle started to drift to the right of the road and go over and crash into a medium near oncoming traffic. The contact was able to place a spare tire on the vehicle for the contact to continue to drive to their residence. The contact took the vehicle to an auto body shop that inspected the vehicle and declared the vehicle a total loss. The contact was concerned that the failure that occurred with the vehicle was a defect on the tire that had blown out. The tires were the original equipment on the vehicle The manufacturer was made aware of the failure. The failure mileage was 11,045.

Drivers rear side tire had a blow involving the tread flying off exactly at the seam it is attached to the tire. This couldn't caused an accident or death to myself or other drivers on the road. These tires were purchased on the vehicle brand new in Sept 19 2020. The accident happened September 15 2021. The vehicle is brand new as well. The other Goodyear eagle sport tires on the vehicle had bubbles which would lead to another blowout. The car has under 25k miles. The car has had oil changes, etc per car doc agreement. There is something wrong with the integrity of the rubber of the tire or they are retreading and selling retreaded tires as new. My son decided with the knowledge of the tire mechanic, to replace all Goodyear tires due to the safety hazard they could create. He had to replace 3 tires.

"The dealer invoice for my 2020 Honda Civic explicitly diagnosed a seatbelt 'internal failure.' Honda Corporate verbally denied coverage by claiming an undocumented seat cover obstruction. I was forced to pay $482.32 out-of-pocket for a safety component covered under Honda's 15-Year/150,000-Mile safety warranty."

While making a slow right turn into a shopping plaza, I accidentally struck a median curb with only the driver’s side front tire. Despite the low speed and minimal impact, the passenger side front airbag deployed without cause, severely endangering my passenger. Aside from a flat tire, there was no damage to the body of the car. Fortunately, we were moving slowly enough to avoid injury, but had we been going any faster, it could have caused serious harm. After the incident, both front seatbelts locked, rendering the vehicle unsafe for both the driver and passenger. I later discovered that there are confirmed recalls affecting the passenger airbag system (specifically the front passenger seat weight sensor) for 2020 Honda Civics—my car’s exact make and model—but my VIN does not appear to be included, despite exhibiting the same failure. When I brought the car to a Honda dealership, I was told the recall did not apply and was quoted $10,000 in repairs for the SRS and seatbelt systems. Rather than addressing the potential manufacturing defect, I was instead hounded to trade in the vehicle. I believe this incident reflects a serious safety malfunction tied to an existing recall and deserves investigation. My vehicle may have been improperly excluded from a recall campaign affecting others with identical equipment and model specifications.

I am writing to file a complaint regarding the air conditioning system failure in my 2020 Honda Civic Sport. The air conditioner in my vehicle began blowing hot air instead of cold air starting in January 2024. I took the vehicle to a mechanic for inspection, I was informed that the evaporator has failed and needs to be replaced. While researching this issue, I discovered that many other Honda Civic owners have reported similar air conditioning problems involving the evaporator and AC system. I also became aware of a 2021 letter involving American Honda Motor Co. and Honda dealership personnel regarding evaporator leaks in vehicles with VIN numbers beginning with 2HG or 19X. The letter stated that Honda was researching these vehicles in an effort to better understand the issue. Given the number of similar complaints and Honda’s apparent awareness and investigation into evaporator leaks, this appears to be a potentially widespread defect affecting these vehicles, even when properly maintained. The failure of the air conditioning system has caused significant inconvenience, medical issues and financial burden. I have severe Hyperthyroidism, and reside in CA. Due to extremely hot weather & no A/C, the heat affected my heart rate and health severely. My honda is utilized daily for employment & commitments. Without proper air conditioning in almost 3 years now, while driving my car, I was admitted into the hospital last summer 2026 for 5 days due to the extreme heat affecting my heart and almost causing me to go into a coma aka [thyroid storm]. I believe this issue should be investigated further, as it may indicate a defect in the vehicle’s air conditioning system. I respectfully request that the NHTSA review this matter and investigate whether the evaporator failure in the 2020 Honda Civic Sport is a recurring manufacturing defect that may warrant further action or assistance for affected vehicle owners. Thank you for your time and attention to this matter.
