general problems of the 2018 Honda Accord - part 2

I had to have $6400. 00 worth of repairs (2018 Honda Accord sport ) due to stalling & engine light came on and then it wouldn't go-due to the head gasket not being recalled and since they had the engine out, I also had to have other repairs they said were necessary plus car rental on top of that. . . I had only made my 2 car pymts when this happened!.

Driving on highway, check engine light went on and car lost all power would not go over 5 mph scared for my life as I was almost hit by other vehicles traveling at hi rates of speed . I managed to get the car to the shoulder. I turned the car off and restarted, and the car went back to operating normal. Car was checked by a friend who is a mechanic, and he told me there were codes for misfires after checking all the issues that could cause that type of problem he informed me that a pressure test on the coolant system revealed a blown head gasket which allowed coolant to leak in the cylinders causing miss fires due to the anti freeze extinguishing the spark of the spark plugs. I researched this matter and it's see to be a very common problem with many Hondas with the 1. 5 engine.

Coolant leaking into head gasket which now needs to be replaced as it’s causing the whole car to shudder when acclerating and when not letting off the gas the check engine light will come on and the car will not drive anymore. It then needs to be turned off and on again to go away and won’t fix the issue with the studdering.

After having fuel pump replaced by recall at random times dashboard will light up with all system lights, car will go into limp mode and loose power for a few seconds and then I am able to resume driving. Extremely scary as there is no warning. This has happened both on the freeway at high rates of speed and on neighborhood roadways. Safety has been compromised several times and Honda dealer is not able to reproduce the issue, retrieve any warning codes or offer any assistance. This has randomly been occurring for several months. When not having this exact issue car runs with no other issues.

I am filing a safety complaint regarding my 2018 Honda Accord equipped with the 1. 5l turbocharged engine. The vehicle has experienced repeated engine-related failures despite multiple repair attempts by an authorized Honda dealership. Problems have included dashboard warning lights, engine misfires, loss of power, fuel odor, and suspected head gasket failure. Most concerning, on September 20, 2025, while exiting a highway with my child in the vehicle, the car suddenly lost power and all dashboard warning lights illuminated simultaneously. The vehicle became inoperable in traffic and required towing. This created a serious safety hazard and could have resulted in an accident. The vehicle has been returned to the dealership multiple times for the same or related issue on the following dates: • July 8, 2025 – mileage 80,099 • July 10, 2025 – mileage 80,101 • September 20, 2025 – mileage approximately 82,000 • October 27, 2025 – mileage 84,453 • October 28, 2025 – mileage 84,473 • April 16, 2026 – mileage 93,812 repairs have included replacement of the high-pressure fuel pump and repeated diagnostic inspections, but the issue remains unresolved. I understand many owners of Honda vehicles equipped with the 1. 5l turbocharged engine have reported similar problems involving head gasket failure, coolant intrusion, misfires, overheating, fuel system issues, and sudden loss of power. I am concerned this defect presents a significant safety risk.

After I took my car in for a fuel pump recall, it caused one of my injectors to be bad which will be 3000 dollars fix out of my pocket. This happened a few months after I took my car to the dealership, and it was doing fine before taken to the dealership for the recall. There are many other owners who reported they experienced the same thing, with all the dash lights came on but couldn’t find the exact cause until they replace their fuel injectors. First, all the alarms appeared, even the engine light was on but they would all go away after a few days. It had been on and off randomly for the past 4 months. The car is still driving fine but the alarms will pop up and stay for a few weeks to a month. It would randomly not letting me accelerate and slow me down, which if I was driving on the highway all the way in the left with traffic, that would cause a traffic jam and eventually an accident with other drivers.

When it is cold outside my acc light comes on and when I started my car the other day it read emissons service problem avoid heavy acceleration and high speed. That was just 1 among 7 other service warning that popped up.

This car is known for its faulty engine. The head gasket tends to blow as early as 40k miles, plenty of people have had this problem and yet there is no recall for the engine or a fix. I was driving on the highway and I was speeding up to merge into traffic and my check engine light started to flash and my car went into limp mode on the highway luckily there wasn't a lot of traffic and I got the chance to pull over and restart my car. I looked online and plenty of people were experiencing this same problem they all had the same answer as well, a blown head gasket. I'm just wondering if someone has to pass away before this gets fixed.

My 2018 Honda Accord ex is currently having fuel injector problems at 41,000 miles. Honda is trying to tell me that fuel injectors do not get affected by the recalled fuel pump. This is very silly because the fuel pump and fuel injectors work together. They want $1,800 to replace the fuel injectors at Honda. I already completed the recall on the fuel pump, and afterward, they told me my injector was running too rich and needed to be replaced for $1800. There are so many Honda 1. 5ts experiencing these same issues, and Honda does not want to do anything about it. I am currently taking my car to a local shop to get the fuel injectors replaced for $1,327. I believe I should be reimbursed since the fuel pump is what caused my fuel injectors to fail. Honda is trying to tell me that two fuel components of a car don’t correlate with each other? this isn’t fair, and I need to be reimbursed.

Head gasket leak after replacing recalled fuel pump. Took my car in for safety recall on fuel pump, just 24 hrs later every check engine light came on and my vehicle slowed to a stop (car went into limp mode). This happened on a busy street with vehicles flying by. I had my vehicle towed to lancaster Honday (CA) where they did my safety recall the day before, they confirmed the head gasket leak. I had my vehicle diagnostics done at a different place as well and they confirmed the bad news, but also said this should not be happening to a new car with 66,000 miles. They advised I call corporate Honda and have them do a goodwill repair where the pay the repair since it is out of its 60,000 miles warranty. I had zero symptoms of this happening before it actually happened. I regularly had maintenance done on my car. I am very dissatisfied and disappointed that Honda just declined my goodwill repair after a month of waiting on them to “review the case”. I couldn’t be more sad and more screwed at this time. $5000 is not something I have right now to take care of something I shouldn’t have to. This is only happening to 1. 5 liter Hondas in my certain year range. I wanted a 2. 0 originally, but the dealership did not have any at the time so I am needing help. I will reach out to the ongoing pending lemon law case in CA to join the base and try to get my car fixed and have Honda do the right thing! I am not happy!.

Check engine lights turned on and turned off all advance features on car because of a faulty fuel injector which is the stock fuel injectors that were designed by Honda.

While trying to accelerate the car loses power. This has happened many times. The Honda dealership has said the system is on back order and they will call me when it’s available. It’s been months. The “jerks”a few times then the check engine light comes on then the car loses power. The dashboard lights are brake system, emission system, electric power steering, hill assist and acc system problem.

Date of incident: [xxx] vehicle information: 2018 Honda Accord VIN: [xxx] incident location: north charleston, SC estimated vehicle mileage at incident: 78,000 miles on [xxx], while starting and driving my vehicle less than one mile, the engine would not accelerate above 10 mph. Following this, multiple service alerts illuminated on the dashboard. The vehicle was inoperable and had to be towed to hendrick Honda of charleston. The diagnosed issue is a leaking cylinder head gasket. This is the second major engine-related issue this year. In may 2025, I paid over $2,000 to repair a faulty fuel sensor injector. This current repair is estimated to cost over $5,000, bringing my total repair costs for this year to over $7,000 for a five-year-old vehicle with just 78,000 miles. This recurring pattern of significant and costly engine failures, particularly the cylinder head gasket leak, indicates a serious safety defect. It is not an isolated incident, as evidenced by publicly filed NHTSA complaints (11677717) for the same make, model, and year with similar engine failure issues at comparable mileage. The sudden loss of acceleration and inoperability pose a direct safety hazard. I am requesting an investigation into this defect and seeking full reimbursement for the recent and past repairs, totaling over $7,000. These are clearly not standard wear-and-tear issues and should be addressed by the manufacturer. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

The fuel injectors became faulty at about 90,000 miles, a mechanic could not identify the issue until about 110,000 miles. A blow head gasket followed.

Car stalled/went into limp mode in the middle of turning onto a busy road almost hit by oncoming traffic. Check engine light came on, as well as all other warnings. Ran diagnostics and show fuel running lean and cyl 2 misfire. Checked all other possible issues related to codes and all signs point to bad fuel injectors.

I was contacted by royal Honda (Honda of harvey, louisiana) about an urgent fuel pump recall on my vehicle. Harris first through text then receive the phone callinstead of scheduling the recall repair, the dealership used the recall notice as leverage to push a $19. 95 oil change special. The representative told me they could “set me up for the oil if I scheduled the recall,” but their focus was on selling the oil change, not correcting the urgent safety recall. When I declined the oil change, they said they were having “technical difficulties,” promised to call me back, and never did. As a result, my recall remains unresolved. This is a misuse of federally mandated recall notices for sales purposes, and it delays urgent safety repairs. Requested action: investigate Honda of harvey / royal Honda for using recall notifications as a sales tactic and ensure my recall is completed promptly.

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).

At approximately [xxx]. Pacific, I was traveling southbound in the fastrak lane of the [xxx] departing from pleasant hill, California headed to pleasanton, California. As I began to accelerate, the engine began to sputter. Immediately, the check engine light flashed on, then the dashboard reported a number of issues ranging from brake failure, tpms failure, power assisted steering failure, vehicle stability assist failure and a number of other issues that I have never encountered since purchasing the vehicle. The sudden deceleration almost resulted in other cars impacting my car as this occurred during the morning commute. I was able to safely navigate off of the freeway. I was on speakerphone with Honda when this occurred. Had I not acted swiftly, a potential high speed rear end collision was likely to have occurred. I immediately took the car to concord Honda. The team at concord Honda performed a diagnosis and advised me that my head gasket was leaking water into the combustion chamber which resulted in the sudden loss of power. I was and continue to be dissatisfied with the handling of this issue by Honda as my car has never been handled by another mechanic. My car has a perfect or near perfect maintenance record and should not have a blown head gasket at 80k miles especially since my car is meticulously maintained and serviced by concord Honda. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

This car came with problem and I want to this if Honda can fix it for free since its they mistake.

As I was driving myself and child on the interstate 65 mph the vehicle all of a sudden dropped speed and would not accelerate. I drifted the car off the interstate off ramp and pulled into a store parking lot. Luckily, we did not cause an accident or hit anything or anyone. All the lights on car's dashboard blinking some examples are eps, vsa, malfunction lamp, breaking system, check engine light, etc. My car did not show that it was running hot, was not smoking, however would not accelerate. The car had a slight rattle, running bad, shaking slightly; all in all, not working appropriately. No earlier indication that something was wrong just came all of a sudden, no warning at all. Car was brought to billy navarre in lake charles, la, where they concluded that head gasket was blown. I had to come out of pocket to fix the head gasket and all of the other problems that it caused. Car milage 84,097, bought brand new in 2018. This is a major safety issue for the public! multiple people have this same problem. I have documentation on all the work the dealership completed. And I have filed a report to Honda.

My 2018 Honda Accord is having major engine problems. Earlier this year all of the lights were coming on, 7 of them at a time, and that happened for a few weeks before it started overheating. If I was driving over 50mph, it wouldn't overheat, but if I was driving slow or idling, it was overheating within minutes. I took it to the shop in June where they discovered there was no coolant inside the engine. They put 1. 5 gallons of coolant in there, and it fixed the problem temporarily, but 2 weeks ago, all of the lights started coming on again. I called my mechanic, and he said his friend had a 2018 Honda Accord that was doing the same thing and that we need to approach Honda and ask them to fix the problem. Turns out a lot of other people on the internet are reporting the exact same problem in their 2018 Honda Accords too, and there's even a class action floating somewhere out there because coolant is leaking into the chambers. We already had a fuel injector recall replaced by Honda last year.

Emission system, low acceleration to the point it becomes a safety hazard in the freeway, I almost got rear ended twice, the car jolts, it stops out of no where, head gasket issues at only 65k. Maintenance was kept up but there’s a facebook group called Honda sport 2018 to 22 on these models of the same issue “christmas tree lights”.

I currently own a 2018 Honda Accord 1. 5l 4 cylinder with only 62,800 miles at the start of the issue. Around the end of July 2025 the car started to jerk. It started with a slight jerk and escalated daily, over about a week, until the car started going into limp mode. The car was taken to a repair shop near my house. This shop said they were receiving an engine misfire code, replaced all spark plugs, and car driving good again. Around 8/15/2025, I started having the same issues. On 8/19/25 the car went into limp mode again in a busy highway. Took it to a Honda/Acura repair shop. They again found the same misfire codes, replaced 1 spark plug, and the car was driving okay. This Honda/Acura shop found low coolant in the engine and believed I had a leaking head gasket as they have been seeing a high number of Honda 1. 5l engines, similar years, with this issue. The shop suggested I contact Honda as it is a known issue. On 8/19, the Honda dealer service department told me they are seeing a lot of that issue but Honda has no current plan to extend warranties or issue a recall, despite the widespread, known issue. The dealership’s service department instructed me to call Honda corporate to discuss the issue and potential coverage. Corporate did open a case for a potential good faith repair. I was told that I would have to take it to a Honda dealership for official diagnostics, pay that fee out of pocket, then submit documents and info for coverage review. The car was driving okay for about 1 week and on 8/27/25, began having the same problems. I was able to get an appointment on 9/2/25 at the dealership. On 9/2/25, the dealership confirmed the head gasket is bad and the car requires head gasket, head bolt, belts, fuel injector, and coolant replacement, and oil change. The dealership again acknowledged this is a known issue with the vehicle. These vehicles are stopping on busy highways (with speed limit of 50mph) and interstates or going into limp mode, not going over 20mph.

I have a 2018 Honda Accord 1. 5t I have always done oil changes and maintenance Accordingly. My car went into limp mode over the summer. I brought it to my dealership who said the head gasket was bad and it was going to cost over 5,000$ to fix. This is a known problem on these cars as I have gathered information all over the internet. Honda refuses to do the right thing and have a recall. I do not have the money to replace the head gasket at the hefty dealership level. I have been waiting over 3 months in an attempt of a diy replacement. The company I have been ordering with has had many issues and I am still without a vehicle. The vehicle only has 138,000 miles.

Honda has known for years that the 1. 5l engines installed in 2018 or newer Honda Accords have issues with oil dilution causing major catastrophic engine failures, head gasket damage, fluids leaking into the cylinders, and costly repairs to cars with less than 86000 miles on them. Honda corporation needs to address this concern before someone dies when the cars engine fails on the highway. My vehicles engine failed on a major road when I pushed on the gas peddle and had no power due to these concerns. Dealership stated numerous vehicles are coming in with these concerns right now which begs the question that it is not a one off situation but a failure of Honda corporation.

The engine coolant began to leak into the cylinders of the engine. The engine began to overheat in the middle of the freeway. I had to shutdown the car down and get it towed. The car is available for inspection. Yes, my safety was at risk. Diagnostics from the dealership indicated that the problem is a design flaw with the head gasket being too thin. There were no indications that the car was going to stall until after it stalled. Honda is putting our lives at risk by allowing citizens to drive a car that has an engine become locked/stall/overheat by design and without warning.

Head gasket blown.

July 10th Honda went into limp mode as I accelerated would not drive over 20. Check engine light flashed on then off. Have taken car in several times no codes can be read. Believe it’s cylinder issues or fuel possible head gasket. All vehicle lights has displayed haven’t been able to get reads once car is turned off. Too many issues with no repair fix.

- year: 2018 - make: Honda - model: Accord sport 1. 5 turbo - vehicle identification number : 1hgcv1f34ja089316 I am writing to report a safety concern with my 2018 Honda Accord sport 1. 5 turbo. The vehicle has developed a head gasket problem, which has resulted in significant engine issues. Additionally, I have experienced fuel injector problems, leading to decreased fuel efficiency and rough engine performance. Despite following the recommended maintenance schedule and addressing the issues with the dealer, the problems persist. I have been quoted $7,800 for repairs, which is unacceptable given the vehicle's age and mileage (currently 114,848 miles). I am concerned about the safety and reliability of the vehicle, especially when driving on the highway. The vehicle's blown head gasket has caused ¹: - loss of power, leading to potential safety issues on the road - engine hesitation and shutdown while driving, which can increase the risk of accidents I request that NHTSA investigate this matter further and take necessary actions to address the recurring issues with the 2018 Honda Accord 1. 5 turbo engine. I would appreciate guidance on potential next steps to resolve this issue and ensure the vehicle's safety and reliability. - repair estimates and records from the dealer - maintenance records, including oil changes and fuel system cleanings - correspondence with Honda dealership and corporate office other owners have reported similar issues with the 2018 Honda Accord 1. 5 turbo, including fuel injector problems and blown head gaskets ² ³ ?. Please help us. Investigate this issue and help us the consumers.

I never was informed about the fuel pump recall , all the lights on my car came on , acceleration was slower , car was jerking , and when taking it to Honda they stated 2 of my cylinders has a misfire and water or coolant leaked and blew my head gasket , the car never ran hot and the guy asked did any light come on and I told him for some old reason every light on the dash was on and the car is vibrating while even in park reverse and when it's moving . I've read up on this and there are numerous of people with this same issue and this should mean something , Honda stated it would cost 6000 to fix when they should have already been warning people of the matter ahead of time . For some odd reason the car would just drive 10mph when I am driving jumping out in traffic having to pull over and restart the car . Guy at Honda even stated fuel pump could have been the issue and they have witness this with other cars like mine.

All lights on dash are on at the same time.

While attempting to pass a slower vehicle in my 2018 Honda Accord with a 1. 5l engine, the suddenly lost power and stalled down to 20 mph while I was alongside the other vehicle. This unexpected power loss put my life and the lives of others at serious life threatening risk. I immediately brought the care to a Honda dealership, where the tech was able to reproduce the issue. The performed a borescope inspection and confirmed that coolant was present inside one of the cylinders, indicating a failed cylinder head gasket. This type of failure should not happen, especially on a vehicle like this. I was the repair would cost $6,500. After researching, I learned that this is a known defect affecting the 1. 5l engine and that multiple class action lawsuits have been filed. I also discovered that american Honda is aware of the problem and has instructed dealership service departments to report affected vehicles. In fact, they have even offered gift cards to service advisors who report these cases, but are charging customers for the repairs. That's nonsense. Just do a simple google search and you will discover what I did. During the failure, the check engine light and several other warning lights came on but only the check engine remained on. Since then the car has multiple indicator lights on. Despite multiple attempts to follow-up, the dealership has refused to return my calls. This is a serious life threatening safety concern that deserves immediate investigation. Thank you. Sincerely, [xxx] [xxx] [xxx] information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

Vehicle had a sudden loss of power. Pulled over on highway had to restart. Engine warning said emission system problem. Had diagnostic done several codes po300,po301,po302,po303,po304,po172. Problem seems to be similar to the service bulletin 22-002 dated Feb 18,22 for the Honda Accord 2015-2016. It seems to be a known issue with this engine. Honda should take care of this safety issue.

I own a 2018 Honda Accord sport. About 2–3 months ago, the car began having repeated engine misfires (p0301), hesitation, and stalling while driving. At the same time, multiple dashboard warnings appear, including steering assist reduced, brake system problem, collision mitigation braking system problem, adaptive cruise control system problem, emission system problem, and hill start assist problem, these failures occur suddenly while the vehicle is in motion, creating a serious risk of loss of engine power, reduced braking performance, loss of steering assist, and disabled crash-avoidance systems. I have already performed extensive maintenance: new ignition coils, a full tune-up, compression test, spark test, and battery/alternator check, yet the issues remain. Diagnostic scans also showed u0416-68 (invalid data from abs/vsa module) in addition to the misfire. This suggests not only a fuel/propulsion defect but also a possible computer/control module failure that links engine, brakes, steering, and adas systems. These conditions match known recalls for the Accord, including 23v858000 (fuel pump failure), 20v314000 (low-pressure fuel pump), and 20v771000 (bcm software issue), yet my VIN does not currently show as included. The fact that multiple critical safety systems fail simultaneously makes this a major safety hazard that could easily lead to an accident if the car stalls, loses braking, or loses steering assist in traffic. I opened a case with Honda customer service (case #15868389), but they refused to cover the repair since my VIN is not listed, despite the failures being identical to those described in the recalls. I strongly believe my vehicle should be included, and I request that NHTSA investigate whether the recall VIN range needs to be expanded.

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.
