2018 Honda Accord complaints

Every light on my dashboard is on i done took it to honda an had the lights turned off server times still on

All of the lights in the dash came on . We took it to Honda , at first they said it was the coils and spark plugs. I had them replaced , the same thing happened again the computer read that it was misfiring on one of the cylinders . They kept it and ran several tests . They then tried to say that it the result of a bad oil change but we knew better. After about a month they said that it had over heated and blown the head gasket . I ended up having to use my warranty and pay a deductible.

UNKNOWN. My 2018 Honda has all the lights on in the dashboard and I’m getting a lot of warnings as well. I took it to numerous mechanics and they all say nothing is wrong with the vehicle. The lights turn on and stay on for multiple weeks then they turn off but then they turn on again. When the lights turn on I notice I cannot accelerate as fast and also all the safety features do not work. This issue started happening around mid 2023.

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

See attached document for complaint.

Car goes in limp mode once the brake system lights come on. When the brake light system comes on, none of the functions for the automatic breaks or electrical portion of my vehicle works. The car will act as if it will not accelerate right before the codes start to appear on the car.

I took vehicle in because of all the sensors were going off. Honda ran a systems check and said fuel injectors needed to be replaced. It is all over the internet that this is a known issue and a recall was not issued. I spent $1500 on the replacement. These should not need replacing on an 18 accord with 80,000 miles. The recall on the fuel pump has not been addressed because Honda has limited parts. How do I know this did not affect the fuel injectors

I own a 2018 Honda Accord (1.5L Turbo Engine) and I have kept regular maintenance on the vehicle. I currently have 146,600 miles on the vehicle. I begin having problems last year as I was leaving work and my vehicle wouldn't start. I waited a few minutes for the vehicle to start and it started and several malfunction lights came on the dash including the engine light. I had a 30 minute drive home and as I was driving home the vehicle didn't want to pick up speed to the speed limit of 65. I drove slowly home. I had already made an appt with the Honda Dealership where I get my car serviced for an oil change a couple days before. The next day I had a family member to follow me 30 minutes away to the dealership to drop my car off. When I dropped the car off I told the service technician about the problem. Later that day the dealership's service department called to tell me that I my head gasket had blown and it would be around $4500.00 to repair. I began to ask questions as to how this could happen I had kept up with regular maintenance. The service technician begin to tell me different reasons, and I asked how when I had regular maintenance and some suggested maintenance required as well. I had my vehicle towed from the dealership to get a second opinion. The technician I took my vehicle to was authorized to work on Honda vehicles, and he asked me if I was aware of the complaints customers were having about their Honda 2018 (same model) was having about leaking coolant, cracked

The Head Gasket is leaking at 135k miles after changing oil and filter every 5k miles and flushing coolant every 50k. Just a cursory internet search will show you how obvious the design defect is in the head bolts of the 1.5 liter turbo engine and they should be recalled.

The contact owns a 2018 Honda Accord. The contact received notification of NHTSA Campaign Number: 23V158000 (SEAT BELTS); however, the part to do the recall repair was not yet available. The dealer was not contacted. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The manufacturer was made aware of the issue. Parts distribution disconnect.

Blown Head Gasket after taking my car in to Honda cars of Rock Hill SC, I had no issues, only took it to have the Fuel injector recall done, they did a diagnostic nothing came up, they did the fuel injector recall repair, and they asked if they could do the oil change i told them yes, a week later, my car lost power on interstate 77N in rock hill south carolina. I was going about 70 mph and it dropped from 70 to 20 mph in a matter of seconds, i had little time to get out the lane, i could have been killed or killed someone else i was terrified. Every known light on my 2018 honda accord came on, I have a video of the lights on my dashboard. I had it towed back to honda cars of rock hill on 5/30/2025 and was told I had a blown head gasket...I asked them how, they just put a fuel injector and nothing else was wrong with my car. they told me cost is $5500.00, i told them there as nothing wrong with my car prior to them doing the recall, Matt told me there was nothing i did, so i asked him what did they do to my car, I need them to replace my motor who knows what other damage happened my car had no issues.

During interstate driving vehicle detected both road departure and engaged the emergency automated braking. The vehicle attempted to correct the "road departure" by steering the vehicle away from the perceived problem and engaged the brakes nearly causing a collision as it has done numerous times before. I have reported this to NHTSA and American Honda and await a repair of this dangerous issue. Honda has opened a case on this but have had 6 months and no response has been issued.

The contact owns a 2018 Honda Accord. The contact received notification of an unknown recall. The contact stated that while driving at various speeds on several occasions, the check engine warning light blinked, and the vehicle lost power. The vehicle was restarted after each failure. The vehicle was not diagnosed or repaired. The manufacturer was not notified of the failure. The failure mileage was unknown.

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..

My 2018 Honda Accord has become unsafe to drive. The car will not go over 15 mph, all the warning lights on the dashboard are on, and the engine and transmission feel shaky. The entire car shakes when I try to drive it, and it seems like multiple systems are failing at once. This happened suddenly and has made the car undriveable. My safety was put at risk because the loss of power happened while I was on the road. The problem has been looked at by my independent mechanic, but it has not been resolved. The vehicle is available for inspection.

Car falls into limp mode in traffic when a misfire is detected. I have had a mechanic investigate the misfire and has determined coolant in the cylinders, indicating a blown head gasket. This is a widely reported problem with this engine and the large number of complaints indicate this is a safety issue caused by Honda.

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 whe

The door locks are unresponsive using both the fob and the vehicle controls. The problem started with a rear door not locking or unlocking when the other doors would lock. Eventually all doors became unresponsive. The doors now require me to manually lock each and use my fob key to unlock the driver door and manually unlock each door. I've replaced fuses to try to resolve the issue with no luck. It seems that the door lock actuators failed prematurely.

This is about the 5th time this has happened to the car. All warning lights appeared spontaneously while driving. The lights would turn off if the car was turned off for a long period of time or is we disconnected battery for a long period of time. We have tried to research the problem and no one seems to know what the cause or permanent fix is.

My locks failed and it took several repairs and they are still not working properly. I fear for my safety and the safety of my children. Honda told me sometimes locks just don’t work but that’s not appropriate to me as I paid the extended electric warranty but they cannot fix them. No knowing this will not go all through the life of my vehicle is a big issue.

The vehicle was totally inoperable and suddenly came to stop was lucky that was driving in a local road where there was no vehicle, suddenly all different warning signs were coming on the dashboard and couldnt drive at all and vehicle was totally stalled. it was very dangerous situation luckliy i was just came off a very busy road otherwise coudl have been major incident. Currently the vehicle is at dealership nto sure what they will say but just wanted to report this as it is very dangerous situation

Faulty/Leaking blown head gasket Causes car to stall

Head gasket failure Causes car to stall

The contact owns a 2018 Honda Accord. The contact stated while driving at an undisclosed speed, the vehicle stalled and then went into LIMP Mode. The vehicle was able to be restarted. The contact received notification of NHTSA Campaign Number: 23V858000 (Fuel System, Gasoline). The dealer was contacted and confirmed that parts were not yet available. The manufacturer was made aware of the failure. The failure mileage was approximately 150,000. Parts distribution disconnect.

The head gasket is leaking. Yes, the dealer reproduced and diagnosed the problem. There were no lights on the dash. It is available for inspection if needed.

Apparently the coolant is leaking into chamber 2 and 3 and it’s burning it and I need to replace the head gasket. Spoke to and looked up a bunch of other people have had this same issue. It’s causing my car to stutter and it’s scary.

The contact owns a 2018 Honda Accord. The contact stated while driving at approximately 60 MPH, the vehicle lost automotive power, and unintendedly shifted to LIMP Mode. The contact stated that several unknown warning lights were intermittently illuminated. The vehicle was taken to a dealer where it was diagnosed that there was an internal coolant leak, and that the head gasket needed to be replaced. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 164,897.

I am writing to report a serious mechanical issue with my 2018 Honda Accord 2.0T that I believe may constitute a design or manufacturing defect with potential safety implications. At approximately 112,000 miles, the engine in my vehicle suffered a blown head gasket, which my mechanic determined was caused by a stretched timing chain. This failure followed roughly nine months of unexplained coolant consumption, during which time no visible leaks were detected. In addition to the coolant loss, the vehicle experienced two separate instances of entering limp mode while driving, creating a significant safety risk due to sudden loss of power. Furthermore, during the winter months, I repeatedly lost cabin heat, suggesting early signs of internal engine issues related to coolant circulation or combustion gas intrusion. These symptoms point to a progressive failure that was not addressed by any recall or Technical Service Bulletin (TSB) during my ownership. Given the growing number of reports from other 2.0T Accord owners experiencing similar issues with premature timing chain wear and associated engine damage, I believe this may be a systemic issue that warrants investigation by NHTSA. A stretched timing chain causing catastrophic engine damage can easily lead to unexpected stalling, limp mode, or loss of control in certain conditions — all of which raise concerns about vehicle safety and reliability.

• Head gasket • None of the safety features work when there is a head gasket issue. Power steering is reduced as well as break performance • Confirmed by Honda dealership with a Boroscope • Honda • No warning, Honda at first thought it would be fixed by fixing the factory recalls. Light went away prior to taking it in and then looked in to it 2 weeks later and diagnosed head gasket failure

The contact's wife owns a 2018 Honda Accord. The contact stated that while his wife was driving at various speeds, several unknown warning lights were illuminated. The contact stated that the warning lights were illuminated constantly. The vehicle was taken to a local dealer, where it was diagnosed and determined that the fuel system was contaminated with water. The contact stated that the dealer replaced the spark plugs and flushed the fuel system; however, the failure recurred while driving. Additionally, the contact stated that the cruise control mode was no longer functional. The vehicle was taken back to the same dealer, where the contact was informed that further diagnostic testing was needed to determine the cause of the failure. The vehicle was not repaired. The manufacturer was informed of the failure, but the contact had not received a call back. The failure mileage was approximately 66,000.

Hello, the fuel pump which is recalled on my vehicle failed and was replaced with an aftermarket pump so I could take it to the dealership. Once I took it the dealership refused to go ahead with the recall and basically told me it’s not their problem. They are required to get it done for customers but they refused to fix mine.

UNKNOWN I received the notice that there was an active recall on my 2018 Honda about the 1.5 Fuel Pump. I have scheduled several appointments to fix this, only for Honda to cancel all appointments related to the recall, stating they didn't have the part. I was headed to work, and every light on the dashboard that could come up, came up. There were several warning lights from brakes, transmission, collision, engine, etc. I took the car to the dealership, and they discovered that the fuel injector was the culprit. I am outraged because they're denying there's a connection, and I believe otherwise.

My 2018 accord sport started randomly started popping up a “supplemental restraint system problem” on my dashboard. It’s turns on and goes away randomly. I went to my local Honda dealer and I asked them about it and they had to preform a diagnostic for $250. Our Honda dealer wants to charge $4000 to repair it. I wrote to American Honda and submitted a support ticket, they asked for a new Diagnostic and charged us another $250. They called me back yesterday saying that they wont pay for the repairs unless there is a recall. How many people need to have the same issue to initiate a recall? There are a lot of complaints online for this same thing. It is airbag safety related.

The contact owns a 2018 Honda Accord. The contact stated that while attempting to start the vehicle during cold weather, the vehicle hesitated while starting. The contact stated that while driving at an undisclosed speed, the vehicle independently went into LIMP Mode. The check engine warning light illuminated. The vehicle was taken to a local dealer, where it was diagnosed with a blown head gasket and a GDI injector failure. The vehicle was not repaired. The manufacturer was made aware of the failure. The failure mileage was approximately 116,000.

I purchased this 2018 Honda Accord that has had no major problems until the last 6 months. I purchased the car from Gerald Jones Honda and have had all repairs and maintenance done there with the exception of tire related concerns and occasional oul changes. All the issues I've experienced have been engine related and in the same area of the engine. Consistent leaks, repeated warning lights, and loss of speed. I have replaced fuel injectors, a head gasket, and a turbo in the last 6 months. Despite those repairs, I'm still experiencing leaks and flashing warning lights. Honda currently has my car due to warnings again. They have indicated it is a performance issue but can't locate the problem. Even suggested I continue to drive the car as they have been unable to duplicate what caused it. I told them to keep it because that makes no sense for me to drive it as it seems unsafe to do so and I could potentially make matters worse. I've spoken to several 2018 Accord owners who have experienced the same issues. This is very concerning to me and crippling my finances. Honda stands out for their reliability, but regrettably the 2018 1.5L turbo doesn't stand up to Honda's reputation.

Various 2018-2022 Honda Accord owners had fuel injector failures caused by the faulty factory fuel pump molding. The fuel pump has been recalled; however, not before the fuel injectors fail. My Accord recently got an array of warning lights pop up on the dash while driving on the highway. I read the code and it was a cylinder 3 misfire. A diagnosis has led to the discovery that the fuel injectors are failing, most likely because of the bad fuel pump molding affecting the pressure of the fuel lines. Not only could this have led to my car stalling on the highway, it led to a complete disabling of my safety features while driving. Honda should be held responsible for the fuel injectors failing caused directly by their fuel pump molding deviation.

My 2018 Honda Accord Sport has been experiencing issues with its automatic emergency braking system, specifically the Collision Mitigation Braking System (CMBS). The system has been activaing unexpectedly, causing the car to brake without an apparent reason. I’ve been trying to keep a list of locations that it has happened and it usually occurs under overpasses when the light changes from light to dark. I’ve reached out directly to Honda and the dealership and neither took my inquiry seriously.

Engine keep going into limp every now and then and it’s pretty dangerous especially while driving on the highway. All the lights would come on the dashboard. On May 2 it almost cause an accident because it happened while I was driving on the freeway and I’ve changed spark plugs, injector my battery and it’s happening

All lights on dash Illuminated. They have come on several times. While driving. You don’t know if brakes, engine, acceleration will work. Limp mode activates or not. Fuel injector seems to be a problem with misfiring or some other issue

My vehicle is stalling out. The engine failed. I was traveling and had to pull off the interstate and stop and restart vehicle. It was very dangerous as traffic was going at a high rate of speed. Yes the vehicle has been confirmed by a dealer. Yes all the warning lights are on in the vehicle.

This car had a manufacturer recall for the "fuel pump". I was advised by Honda to go get the car checked by the dealer to evaluate if the issues I was getting were related to the recall. I paid close to $400 to get the car diagnosed and about 3/4 months after that I was told that the part is available for the recall service. I got the repair scheduled at the dealership and got the part replaced. Ever since I got this fuel pump replaced, now the car is struggling to pickup. It looks like a miss fire but it doesn't show any errors on display. In this condition, this car is not safe to drive around as it is skipping the engine thrusts. I have looked at Honda website and other online resources and people are talking about these issues but HONDA hasn't said or done anything about it. It all started after I got the fuel filter replaced.

The 1000 miles or so, when trying to increase speed, would feel the gears slip between revolutions. I would let up on the gas pedal then slowly resume pressure, which sometimes worked or sometimes didnt. On April 19th while going up a hill on a side road, the car stalled and transmission warning light came on. I pulled over and shut the car off and restarted was able to slowly continue up hill at 15 miles per hour with the slipping becoming worse ( this is when I first called Honda to bring it in on Monday April 21.) I was able to arrive to work. After leaving work I pulled out of the parking lot and the car just stalled with all lights and warnings going off from engine to airbag warnings to tire pressure lights going off and dinging. This is when i called a tow truck to tow to the Curtiss Ryan Dealership. After talking to them at dealer they told me that other accords have had this problem.

This vehicle was built terrible. It had a blown head gasket at 86,000 miles. The head was warped. My valve guides and seals were compromised and leaking into the combustion chamber. I need a full head resurfacing job with new gaskets all around. New injectors and new valve cover gasket and everything around. This car has a design flaw and needs to be recalled for mediocre heads life. It almost caused me to get crashed from the back from a semi truck because the car decided to lose complete power while on the road. The cars recalls have been addressed but this whole issue with the faulty heads needs to be addressed. My vehicle is in the shop now and I will have to pay a little over $4,000 now. It's a hazard on the road when you get near to 90,000 miles.

Took in my vehicle to Rock Honda in Fontana at 125,000 miles for a second fuel pump recall. Two years ago my car stalled on me as I was driving on the freeway, it immediately decelerated from 65 MPH to 40 MPH, this happened before I had the first fuel pump recall fixed. Did the second fuel pump recall, and days later my car again began to decelerate from 50 MPH to 5 MPH. Brought it into the dealer and they told me my head gasket was blown.

Scanned for codes. Found P0303, P0299, and P2243 stored. Found coolant entering cylinder 3. Found excessive play in the waste gate rod and found A/F sensor is not responding. Needs head gasket. Vehicle starts up and runs rough. All alerts on alerts on dash on cust states check engine light on. Honda sensing alerts on.

Cylinder 1 misfire intake air leak incorrect fuel pressure insufficient compression in cylinder faulty or improper spark plugs poor connection at fuel injectors open or short in fuel injectors circuit clogged fuel injectors poor connection at ignition coil open in ignition coil circuit faulty ignition coils

Headlight lenses crazing inside lens surface, deminishing headlight brightness.

The collision mitigation braking system is engaging while I’m driving with no obstructions in front of me. The car slows down completely while I’m on the highway almost coming to a complete stop. This has happened numerous times since Dec 2024. I took it into Honda and they did absolutely nothing besides charge me over $500 for diagnostic fees and told me to get an oem battery and bring it back to be inspected again.
