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.

The fuel pump had to be recalled and caused the fuel injectors to start failing.

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.

Malfunctioning fuel injectors causing misfires stem from a known issue with faulty fuel injectors; a problem widely reported across multiple Honda models equipped with the 1. 5-liter turbocharged direct injection engine. Notably, the Honda cr-v (2019–2023), civic (2019–2022), and Accord (2018–2022) have all been consistently linked to fuel injector failures. The most serious safety concern associated with this defect is the potential for sudden throttle changes, which can trigger the check engine light, cause the engine to lose drive power, hesitate, or even stall—all of which significantly increase the risk of a crash or injury.

The vehicle displayed engine warning message “emission system problem” at 70,000 miles and this appears to be present in many vehicles of this edition.

When the fuel tank was at 1/4 full/empty, the car started stalling on the highway. We were able to go to a gas station and filled the gas tank. The problem was gone. We went to our mechanic but he could not find the problem. A few day's later the gas tank was 1/2 full/empty and the same problem happened. We filled it up and the problem was gone. We went back to our shop and the mechanic did a diag but didn't find any fault codes. He advised to go to the Honda dealer to take a look at it.

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.

On three different occasions earlier this year 2025, my car electric system would completely shut down. My safety was put at risk because this would often happen while I was driving. After three different diagnoses at two different dealerships, the san francisco dealership found that there was a fuse shortage and it was an electrical problem. They were able to fix it and I paid out of pocket. Now, in July 2025, I was again on the road driving when I get an error message on the dash: emission system, problem, and cooling system problem. I was not able to accelerate my car. Again my safety was at risk. I had to stop on the street, turned off my car, and when I tried turning it back on, the engine would not start, but the electric system was fine. My car is a 2017 hybrid Honda Accord – it is way too new to be having all of these issues. I always take my car for maintenance regularly and my car is in good condition.

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.

My vehicle dashboard was lit up like a christmas tree with over $3. 1k in repairs only for it to be the fuel pump!.

Fuel pump failed, car stalled and was unresponsive.

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.

While driving my 2017 Honda Accord, I suddenly lost the ability to accelerate when pressing the gas pedal entering the freeway. At the same time, the check engine light flashed along with multiple other warning lights, which caused the car to go into limp mode. This put my safety at risk, as I was unable to speed up in traffic, creating a dangerous situation. Same situation occurred the next day - narrowly avoiding the accident. The car is not safe to drive. Honda dealership determined issue was due to a fuel injector failure, on a very well-maintained vehicle it seems strange for this issue to come up. I believe this issue is directly related to the faulty fuel pump which is being recalled for many 2017-2018 Accords as the defective fuel pump caused excessive strain on the fuel injectors over time, it could explain why so many owners, including myself, are experiencing premature failures. Given the safety risks involved and the growing number of similar reports, I urge NHTSA to investigate this issue and hold Honda accountable for addressing the problem and cover the cost of the injection repairs.

On several occasions, as I’ve traveled down the interstate, getting off of an exit the car engine completely shuts off and dies before coming to a complete stop.

Frequently, my vehicle experiences a misfire, particularly at highway speeds. The check engine light has turned on and flashed, indicating an engine misfire. The vehicle does not immediately respond when the throttle is engaged, presenting a safety hazard while the vehicle is moving. All spark plugs and coils have been replaced and the problem persists. Other trims and similar models exhibit a fuel pump failure and have been recalled due to a manufacturer defect. I am asking for my model (2017 Honda Accord ex-l, fwd) to be included in the recall and for my fuel pump and affected systems to be replaced.

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.

Car is giving a p0301 error. Replaced coils and spark plugs still giving error. The problem is fuel inejectors. Gives car a rough idle at start up.

Vehicle shakes roughly and vibrations on this 2024 Honda Accord hybrid when transitioning from electric to gas motor at idle. This occurs sporadically but generally when idling in traffic or a drive thru etc. The electric motor is working in this idle stage, but when the heater or ac is on and you are idling for a period of time, it will kick on the gas motor causing shaking of the vehicle. This occurs mainly when the gas motor is kicking on from idle and sometimes when it shuts itself back off again. This problem was reported to selling dealer smail Honda at a service appointment on 6/9/25. Tech did not find the problem and left these notes: "scanned computer for faults and none present. Vehicle operating as designed. " in my opinion, the vehicle is not operating as designed and this could be a possible safety issue so I'm filing this incident with NHTSA.

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.
