general problems of the 2018 Honda Accord - part 1

As soon as I got to work and put it in park I got a message on the dashboard saying “engine temperature too hot. Do not drive. Allow engine to cool”. No other warning signs were shown before this. I looked up on google what maybe it meant and to my findings it mentioned gasket and all I noticed recent complaints and claims filed with 2018 Honda Accords for a known issue with these Honda Accord sport 2018 models for blows gaskets.

A 2018 Honda Accord suddenly displayed multiple dashboard warning messages at the same time after previously operating normally. The warnings include: emission system problem (avoid heavy acceleration), tire pressure monitoring system (tpms) problem, brake system problem, brake hold system problem, electric power steering system problem, vehicle stability assist problem, hill start assist problem, adaptive cruise control system problem, collision mitigation braking system problem, and road departure mitigation system problem. These alerts appeared simultaneously when the vehicle was started, even though the car had been driven the night before without any issues. The vehicle still starts and runs, but the number of system warnings suggests a possible electrical, sensor, or control module issue affecting multiple vehicle systems.

I wanted to report that this vehicle, According to carfax, had 169,236 miles on August 15, 2025, and 9/4/25, and 85,326 miles on January 24, 2026. That's only 4 months! the odometer was tampered with, and this seller knew it was altered because it went through 5 different sellers in those 4 months. I don't know if their reports are true or false, which is why I'm writing to see if you can help me.

The a/c condenser on my Honda failed and leaked out all of the refrigerant, which subsequently caused the a/c compressor and related components to fail. This issue is well?documented, and Honda has issued an extended warranty specifically for the condenser due to its known defect. My vehicle was inspected by an authorized Honda dealership, and they confirmed that the condenser failed and that the resulting loss of refrigerant caused the compressor to generate metal shavings. These metal particles can circulate through the hvac system, potentially entering the cabin and posing a health risk to the driver and passengers. Despite the clear causal relationship and the dealership’s findings, Honda is refusing to replace the failed compressor and associated components, even though the failure originated from a part they acknowledge as defective and have extended warranty coverage for. There were no warning lights, messages, or symptoms prior to the failure. The a/c system stopped functioning without any advance indication, leaving me without proper ventilation and climate control. This defect raises both mechanical reliability concerns and potential health and safety risks due to metal contamination within the hvac system. I am requesting that NHTSA investigate this issue further, as Honda’s refusal to cover the full scope of damage caused by their known defective condenser leaves consumers exposed to unnecessary safety hazards and significant repair costs.

I had a coolant link problem they couldn't find or fix even after taking it in over 4 times ,how I have a blown head gasket ,also different components in my ac keep going out have had to fix 3 times in the last 3 years, both these are know issues for this year Honda.

I have a 2018 Honda Accord sport 1. 5 the issue started after getting my fuel pump replaced as part of the recall. While driving, all of the dashboard lights came on. Warning messages kept flashing on the dash. This car was driving perfectly fine before the fuel pump was replaced. When the codes are cleared, the car drives perfectly fine. The dashboard lights will periodically turn off but ultimately come back on and as a result, the car goes into limp mode. Coils, sparkplugs, breakers have been switched out and oil levels have been checked. When the car is scanned, the codes are reading a misfire with the coils but, the coils that are allegedly misfiring were just replaced. The car jerks while attempting to accelerate, and after a few miles, it goes into limp mode. I have tried every type of repair that has been suggested to me by the mechanic but the issues persist.

On Nov 7, 2025, I took my 2018 Honda Accord (VIN: [xxx] ) to "Honda of gainesville" (dealer #208034). 1. Recall negligence: the dealership performed unauthorized repairs on the vehicle's fuel system (alleged fuel injector failure). However, while the vehicle was in their service bay for fuel system work, they failed to perform or even disclose active NHTSA safety recall 23v-858 (fuel pump), which is open on this specific VIN. The dealership prioritized unauthorized, billable fuel repairs while knowingly releasing the vehicle with a mandatory federal safety defect still present in the fuel system. 2. Safety coercion: service advisor [xxx] used safety fear tactics to coerce the unauthorized work, claiming the vehicle was entering "limp mode" and would become inoperable/dangerous to drive. Independent diagnostic analysis (obd2) performed after the service revealed zero error codes and no history of the claimed failure. The dealership fabricated a safety hazard ("limp mode") to generate revenue while ignoring a real safety hazard (recall 23v-858). Associated investigations: a formal complaint regarding the unauthorized repairs has been filed with the florida dept. Of agriculture (case #xxx-xxx). Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

Evaporator for ac failing. This poses a risk for drivers not having property ac in different weather and is extremely dangerous with children. Issue was found by the Honda dealership. I brought this issue up with them on a previous visit after hearing a strange noise, said everything was fine then a week later it goes out and only blowing hot air into vehicle.

On 11/3/25 Honda conducted the fuel injection recall fix. Prior to this, no warning lights were displayed on dash. 11/11/25 nine different warnings displayed on dashboard board. 11/13/25 at approximately 35mph the vehicle would not accelerate and the 9 warning notifications continued to flash. Cars had to go around me as I tried to find a safe place to pull to side of the road. I turned off the ignition. I took the vehivle back to the Honda dealership maintenance. My vehicle will be there till tomorrow. I was informed code p0304 was present. Prior to recall fix drivability was not a concern and and had no warning lights.

I own a 2018 Honda Accord that was subject to a fuel pump recall. The dealership replaced the fuel pump in July 2025 as part of the recall. Shortly after the replacement, all dashboard warning lights illuminated. I took the vehicle in for diagnostic inspection and was informed that the fuel injector and head gasket had failed. The estimated cost of repairs is $5369. 69. I believe these failures may be related to the fuel system recall or indicate a broader defect in the vehicle’s engine or fuel components. I am deeply concerned about the safety and reliability of the vehicle, especially since these issues arose immediately after the recall repair. I am currently unable to afford the repair, and I fear the vehicle may pose a risk to myself and others on the road. This situation has caused me significant stress and anxiety. The unexpected financial burden has disrupted my personal and professional life, and I feel unsafe driving a vehicle that may have underlying defects. I am frustrated that a recall repair may have led to even more severe mechanical issues, and I am left without clear support or resolution. I had no choice but to pay for the repairs out of pocket, despite the financial strain. I am seeking guidance on how this cost might be recovered—whether through manufacturer assistance, warranty extension, or further recall action. I respectfully request that NHTSA investigate whether this issue is connected to the existing recall or represents a wider safety defect affecting other vehicles of the same make and model.

I have changed turbo, coil packs, fuel injectors, spark plugs, battery, fuel pump and my vehicle still give misfire in cylinder 3. Honda knows it’s a turbo and head gasket issue and will not do a recall on this for the vehicles. Horrible company. Will never buy another Honda.

The sunroof spontaneously exploded while traveling at 50mph. Was not a rock. The sound was extremely distracting and could easily cause a wreck, especially if the sunroof visor was open. Could also cause bodily harm.

Advanced driver assistance systems (adas) this has been ongoing since I had the car and have taken to dear ship several times and they say it to happen, so they get the messages and the messages are there. I look it on google and there have several complaints about this issue and I have Honda and they are very rude about it, I have even call here and the young pay no mine what soever told me to call Honda I need mt=y problem resolve please, I am scared to drive my out state , I am [xxx] and live in north carolina and these people cannot drive. I have pictures which I sent as attachments. Somebody please help me. My payments' are 655. 00 a month and need to fill safe driving this vehicle information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

The ac system on my 2018 Honda Accord 2. 0t stopped blowing cold air due to refrigerant leaks in both the ac condenser and ac evaporator. The condenser is covered under Honda's warranty extension (service bulletin 21-018) which acknowledges a manufacturing defect where r-1234yf refrigerant corrodes the condenser tube walls. The dealer confirmed the evaporator is also leaking from the same corrosion defect. The dealer states both must be repaired together because the system cannot hold refrigerant with a leaking evaporator. Honda corporate is refusing to cover the evaporator repair despite it being caused by the same known manufacturing defect. This is a systemic issue affecting 2018-2020 Accords and other Honda models using the same ac components and r-1234yf refrigerant.

My Honda has 59000 miles on it not even 60k on it since we bought it. Have done all regular services an have done every recall is had. One more my husband goes to leave for work not even got out of the neighborhood an every warning light turns on car start shaking. I take it to my family mechanic who does all of our work on every one of my vehicles. An he said its the head job witch doesn't make since cause of the year an the miles on the car. An I bought it thought car max an got maxcare so I had to take it to another shop prestige auto worksan they say the samething an tells me to go thought all this cause Honda is having problems right now with there vehicles. So now it's been about 2-3 weeks without a car waiting to get fixed.

So about 3 months ago all the sudden all the lights on dash board came on, everyday in the morning when I turn on vehicle on and start driving it does not go over 10 mph even after pressing gas padel all the way, then I have to shut off vehicle for some time and starts back on it start running but lights still comes on. Honda repair shop told me to change fuel injectors which estimate $1,600. But at two different certified mechanic told me Honda Accord has problem with their engine getting coolant in the engine.

My car is always having some electrical issue but when I type in my VIN number, no recalls are listed under my VIN number and then for the last couple of days I've been experiencing acceleration problems when I look up a 2018 Honda Accord it is saying that fuel pumps have been an issue, but my VIN number pulls up no information as far as me falling under that recall what are the proper steps to get my car looked at to see if my VIN number even though it's not populating, any recall falls under the recall.

Hi I just drive my car for about an 1hr and start losing power and a white smoke coming out the muffle I think the head gasket bad.

Backup camera has purple and green distortion that makes it hard to see what’s behind the vehicle when trying to backup. This is a permanent problem that can be inspected upon request. It involves a risk to myself and others by possibly causing injury or property damage. Asked dealership about it and they said it’s common issue and I would need a new camera. Not sure what caused it. It just happened one day and has been like that ever since for about 1 month. Contacted Honda headquarters and they said they couldn’t do anything since there’s no recall with my VIN associated with it. Even a google search shows that there are too many others experiencing the same issue that this should be covered by a recall. It’s very dangerous to allow it to stay like this.

I was traveling at 55mph when the car lost power on the freeway. I had to make my way to the shoulder. I could only travel 10mph. I had the car inspected by an independent mechanic and Honda dealership. I was told it was the head gasket. I am told by Honda it will cost $5500 to fix. I did some research on this issue and found it to be a design flaw due to the channels that are put in the engine block to pass coolant. I found this is a prevalent and Honda did confirm it. Honda denied helping to fix the car and even though they know about the issue. We purchased this car brand new in 2018 and we thought we had a reliable vehicle with Honda's reputation. Honda's good will program did not accept the case either.

This is regarding TSB 21-087, warranty extension for 2018 Accord paint b-757p still night pearl. I was not informed in writing as per required customer notification in 2001. The extended warranty was for 7 years from date of purchase with no mileage limit. When I noticed the paint peel on the roof seams on the left side and right side of the roof, I asked the local dealership today on 7/25/2025. They said I was a few weeks past the expiration date and I had to contact american Honda. While at the dealership getting maintenance performed, I contacted them via chat and they directed me to call instead. I called Honda and they said once the expiration date has passed, there was nothing to be done. I asked for good will and she declined. They will not provide email of incident, as per my request, from discussion but did open case and assigned a case number. Honda stated my only recourse was to pay for damage out of my pocket or wait to see if Honda will possibly extend the warranty and that it was my responsibility to contact them since they will not provide any notification again. So, my vehicle will continue to rust from the paint peel on the roof on a daily basis in the florida sun. Or I have the option to pay out of pocket now and, if warranty extension approved request reimbursement.

Turbo underboost condition.

The speech issues.

Every light on my dashboard came on out the blue while driving.

Head gasket.

Car keeps slamming on brakes on interstate car keeps misfiring cylinders 1. 5 head gasket problems should have a recall with these Honda as much as they give problems. .

On 2025-06-12 at about 3:50 pm est I triggered a remote start command from my phone via the Hondalink app to cool down the car before leaving work. When I went out to the car it had not started. I assumed the command had simply failed, so I returned home and parked in our attached 2-car garage at around 5:10 pm. At about 6:30 pm I opened the door between the house and the garage and heard an engine running. The car was found to have spontaneously started itself. I do not know precisely how long it had been running. It took me a couple seconds to recognize the situation and the danger, and once I realized what had happened I immediately closed the door to prevent carbon monoxide from entering our house. I tried accessing Hondalink to shut down the vehicle remotely but the app gave a message "services currently unavailable". In order to safely shut it down, I opened the garage doors, waited a couple minutes for the garage to ventilate, then quickly moved in and shut down the engine while avoiding breathing in. We noticed a smell of fumes in our house near the connecting door. Both keys were in static locations (not in pockets, etc. Where the buttons could have been accidentally pressed). They had been that way since I got home. I believe that Hondalink's servers sent the remote command to my vehicle *significantly later* than the command was requested. This is a major problem and safety checks should prevent a delayed command from having an effect on the vehicle, especially when dealing with engine start commands. The carbon monoxide buildup fortunately seemed to be minimal, although I am again unclear exactly how long the engine had been running. The vehicle will normally shut itself off 10 minutes after a remote start. However, the most dangerous situation would have been if the car shut itself off and then someone entered the garage shortly afterward without realizing that the vehicle had been running.

All lights in dash is on took it to Honda they playing a guessing game injectors head gasket sensors they really don’t know many people are complaining with the same problems.

Condensor leak and compressor not working. Condensor replaced under Honda service bulletin but compressor not holding pressure.

Paint at the center top of the vehicles roof is slowly starting to fade and chip away. I've always hand washed my car since I bought the vehicle in 2019. Noticed the paint at the top of the roof has been the only area where this is happening.

My car started misfire . . All the lights went on the dashboard . . Had to get it towed . . Headgasket issues.

My vehicle registration renewal notified a recall on the vehicle by the national highway traffic safety administration.

I got this car April 2024. By December I went to the Honda dealer for the recall even though nothing was wrong with the car. After December, when I got the recall fast forward to February. My engine is stalling. I could be pulling out my driveway and it’s stalling. I could be going 10 mph and it’s stalling. I was coming off a ramp and almost got smacked by a 18 wheeler because it started stalling as I’m coming off the ramp. It break checked me on 5th Ave. I was driving. No car in front of me. But a car in the back of me. And it just broke on me. Out of no where. Almost causing the Mercedes Benz to hit me. Luckily they were paying attention. I keep taking it to my mechanic. They are seeing nothing wrong. They don’t want to fix something that’s not broken also after I did the recall for the fuel pump. Now all these lights pop up on my dash. Driving used to be fun. Now it’s getting real scary. I am going to go back to the Honda dealer and see what they tell me but I did look up they have to keep fixing it until it’s fixed. Fingers crossed. I can’t get another car and I also can’t keep driving like this. It’s going to cause an accident.

The lettering of the gear shift and signal light/ wiper switches run off easily making it hard to see in dark places and at night. Bring that those switches are the most crucial when operating the vehicle the white lettering should be sustainable and durable making the visibility great whether driving during the day or night.

Serval warning lights come on in my vehicle I’ve have seen this happen in other models of this car and nothing has fixed it. Car drives fine.
