general problems of the 2018 Honda Accord - part 2

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.

2018 Honda Accord 1. 5t ex trim and I had a head gasket completely blown at around 82,600 miles. I, alongside with many many other 1. 5t Accord owners, am experiencing this head gasket issue for such a low milage vehicle and it is simply inacceptable and Honda seems to be entirely ignoring this widespread, recurring problem on this engine. Reaching out and file a report in hopes of getting this to Honda's attention so they can address this ASAP. It has been 7 years since this problem and nothing has changed, which is not okay.

While accelerating uphill approximately 65 mph the car suddenly started to shutter and slow down to 35 mph. I forced me to move rapidly over to the right lane on a busy highway almost getting hit by a semi truck. Luckily I was able move to the shoulder and park the vehicle. I shut the vehicle off and tried to start it back up which it did but struggled to turn over. Using my obdii scanner I found that multiple codes had appeared which included p0087 fuel rail/system pressure to low and p0299 turbocharger underboost. Vehicle was towed to my residence where it currently sits until I am able to repair it. Prior to this happening there were no warning lamps or messages or symptoms. The failures first appeared while driving up hill. It was not inspected by manufacturer, police, or insurance. The problem was not taken to dealer or independent service center to confirm since the car is out of warranty and cost to diagnose is ridiculously high. I myself diagnosed the failures and found that the mechanical fuel pump part# 16790-5pc-h02 seized up and was not providing enough fuel to engine. And diagnosed that the waste gate actuator arm was to loose due to worn out bushings. (poor engineering in my opinion since there is no way to replace just the bushings on the actuator causing customers to replace the entire turbo. ) after replacing the mechanical fuel pump the vehicle was able to start up without issue and drives perfectly fine. I currently still have the fuel pump and the turbo is still in the vehicle if needed for inspection.

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.

Bad fuel injectors reported by diagnostic testing done by Honda dealership after recall was completed on fuel pump. All warning lights on dashboard lite up and multiple warnings from car. This is a known issue with these specific Honda engines. Very costly repairs that if not completed can cause other engine issues.

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.

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.

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.

If car is idling for over 1 minute, all lights on dash come on. When all lights on, car wont wont go over mph, car will randomly sputter in highway when going over 1rpm and will stall randomly. Reported on reddit by multiple people and when I went in to get it diagnosed it was the fuel injector issue.

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.

My vehicle is experiencing engine hesitation and it's getting worse every day I drive my car. This is a known side effect of the Honda safety recall notice I originally received in February of 2024. I received initial notification of a safety recall for my Honda vehicle in February of 2024 and it stated the safety issues of a possible faulty fuel pump modular. The letter expressed that they have no available parts but were working on getting them. I then received a 2nd letter regarding the fuel pump in may of 2024 and that parts were limited so they were focusing on customers who were experiencing side effect/safety issues with their car. I then received a 3rd letter in November of 2024 stating parts were ready and I just needed to contact my local Honda dealership to have my fuel pump modular replaced free of charge. I have called my dealership on at least two different occasions and have also taken my car in to Honda since then for general maintenance (oil change) and I keep being told they do not have the parts. The last time I spoke with them, I keep getting told that they do not have the parts. I am also always told they will probably call me in a couple weeks when they have the part but I never received that phone call from them. I can never seem to get a straight answer from them and am always told another excuse as to why my car and my family's safety is not important enough for them. I've even been told some of those replacement fuel pumps are needed for their newer cars.

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.
