2018 HONDA ACCORD Fuelpropulsion System Problems

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!

My dashboard lite up like a Christmas tree. I took my car to Honda dealership. They put it on the diagnostic machine. A blown head gasket, Honda quoted me a repair price of $4400.

I purchased this 2018 Honda Accord Sport brand new from the dealership, relying on Honda’s longstanding reputation for reliability and longevity. At approximately 120,000 miles, the vehicle suffered a blown head gasket during normal driving conditions. The vehicle has been properly maintained according to Honda’s recommended schedule. I have already opened a claim with Honda corporate regarding this issue and am currently awaiting their response. Despite proper maintenance, this catastrophic engine failure occurred, suggesting a design or manufacturing defect rather than misuse. This issue presents both a safety concern and a substantial financial burden, as I am a single mother of four who depends on this vehicle for daily transportation. Based on reports from other owners, this appears to be a widespread defect affecting 10th-generation Honda Accords with the 1.5L turbo engine, which I respectfully request NHTSA investigate.

Sacramento ca , Car stopped in the middle of the highway couldn’t accelerate, won’t let me advance past 20 mph gas fuel was changed earlier in 2025 but I’m sure it’s the fuel injectors

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...

Emissions and engine light turned on which caused enginue to lose power and stall. Took car to dealership for diagnosis, and two codes related to failed fuel injectors and failed turbocharger. Tech said it is a known failure with this vehicle model, especially with the Honda turbo engine, so much so the warranty was increased from 100,000 miles to 150,000. Unfortunately my car was 15,000 miles over warranty and will be a costly bill. Online research yielded that tech was right, it is a known failure issue with this model but I missed the warranty extension. If this is a known issue by the manufacturer, should this not he a recall issue?

I have a 2018 Honda Accord Sport 1.5 The issue started after getting my fuel pump replaced as part of the recall. While driving, all of the dashboard lights came on. Warning messages kept flashing on the dash. This car was driving perfectly fine before the fuel pump was replaced. When the codes are cleared, the car drives perfectly fine. The dashboard lights will periodically turn off but ultimately come back on and as a result, the car goes into limp mode. Coils, sparkplugs, breakers have been switched out and oil levels have been checked. When the car is scanned, the codes are reading a misfire with the coils but, the coils that are allegedly misfiring were JUST replaced. The car jerks while attempting to accelerate, and after a few miles, it goes into limp mode. I have tried every type of repair that has been suggested to me by...

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...

In 2023, the car had a rough start during cold weather. Honda confirmed there was a service bulletin and told me my fuel injectors were likely failing. It’s a known issue. For 2 winters, I used Sea Foam to manage the problem. This winter, the dash completely lit up. I returned to Honda for an update to new version of the same service bulletin. They did the fix but it did not solve the problem. Tonight my car went into limp home mode and had to be towed to the mechanic for the fuel injector repair. We were on NC Interstate 540 when the car rapidly lost acceleration and luckily made it to a gas station for safe pick up. Me, my passenger and other drivers were all endangered the 3 times I had to pull over to stop and restart the car.

Fuel pump is bad causing the car not to start.

The vehicle is misfiring due to faulty fuel injectors. Causing every light on the dash to come on.

After vehicle got serviced an open recall for fuel pump, my car has been having issues. I know is related to the head gasket/fuel injections. My car has been great, monthly maintenance service up until I got that recall fixed. I now regret it getting repaired, but I had to, to be able to receive my DMV tags. I was driving about 45 MPH and vehicle stopped accelerating will not speed over 20 MPH and the check engine light turned on. Just got full transmission flush and oil change and this happened. I read many article online that this happens after this recall repair to the ACCORD 1.5T EX2018

At just under 60,000 miles, the check engine light came on with 10 warnings all at once when the car was started. When I took it to Honda they said that 2 of the cylinders are misfiring and the fuel injectors need to be replaced. These are failing far too early on this model of vehicle and it is likely due to the recalled fuel injector that they took years to replace due to inventory. There should be a recall for the fuel injectors.

Several system warnings. Dealership diagnostic "bad fuel injectors" Vehicle has 62,735 miles.

The problem I am having with my vehicle Honda accord 2018 is with the head gasket. I was on the highway and as I was driving suddenly all the signs came on the display and gave a warning that my vehicle is overheating and it came down to 20mph while I was on the highway. This was very risky to me and the other vehicle around me.

Car has lost power or gone into "limp mode" while driving on multiple occasions. Car was never listed under the fuel pump recall but had all associated symptoms & problems. Had to have fuel pumps replaced in December 2023 due to car not starting because of faulty fuel pumps. Car has been properly maintenced since purchased brand new in February 2018. currently around 121,000 miles. Car overheated this past summer, Coolant seems to be leaking somewhere as just filled with coolant month ago and needed to refill with about quarter to refill to correct amount. Oil also seems to be having slow leakage problem somewhere within the engine as there is excessive oil on drip pan. Had all 4 spark plugs changed in March of 2025. Car has been going into limp mode and looses power for few seconds to minutes sometimes, almost causing multiple accidents while driving on highways....

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.

Engine knock caused by oil dilution which is known manufacturing issues with my model of car.

My car lost power while driving on multiple occasions. My car was originally on the fuel pump recall list but the dealership did not have the part for 6+ months. When the part did come in I found out my car was no longer on the recall list. I had to have my fuel pump injectors replaced due to a faulty fuel pump.

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 own a 2018 Honda Accord that was subject to a fuel pump recall. The dealership replaced the fuel pump in July 2025 as part of the recall. Shortly after the replacement, all dashboard warning lights illuminated. I took the vehicle in for diagnostic inspection and was informed that the fuel injector and head gasket had failed. The estimated cost of repairs is $5369.69. I believe these failures may be related to the fuel system recall or indicate a broader defect in the vehicle’s engine or fuel components. I am deeply concerned about the safety and reliability of the vehicle, especially since these issues arose immediately after the recall repair. I am currently unable to afford the repair, and I fear the vehicle may pose a risk to myself and others on the road. This situation has caused me significant stress and anxiety. The unexpected financial burden has disrupted my...

While accelerating car jerks at times. At time car will go in limp mode I’ll have to safely try to get to side of road turn car off. Restart and continue driving. I’ve changed spark plugs, coil packs, turbo, fuel injectors, fuel pump and battery. I continue to put money into my car and nothing helps.

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

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.

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.

I own a 2018 Honda Accord EX-L equipped with the 1.5-liter turbo engine. Over time, the vehicle began showing symptoms of coolant loss without any visible leaks, a sweet odor under the hood, and intermittent white smoke from the exhaust after startup. The engine would sometimes idle roughly and hesitate under acceleration. No external leaks were found by my mechanic. I later learned that these symptoms are consistent with a possible head-gasket or coolant-intrusion issue affecting this engine type. The problem poses a potential safety risk because coolant can enter the combustion chambers, leading to engine misfire, loss of power, or complete engine failure while driving. The issue has not yet been formally recalled, but I have seen multiple complaints and reports of similar failures in 2018–2022 Accords, Civics, and CR-Vs with the same 1.5-liter turbo engine. A warning light (“check engine”) appeared intermittently, and the temperature gauge fluctuated during...

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...

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...

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.

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...

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...

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.

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...

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.

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.

- Year: 2018 - Make: Honda - Model: Accord Sport 1.5 Turbo - Vehicle Identification Number : [XXX] 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...

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 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...

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...

I got this car April 2024. By December I went to the Honda dealer for the recall even though nothing was wrong with the car. After December, when I got the recall fast forward to February. My engine is stalling. I could be pulling out my driveway and it’s stalling. I could be going 10 MPH and it’s stalling. I was coming off a ramp and almost got smacked by a 18 wheeler because it started stalling as I’m coming off the ramp. It break checked me on 5th ave. I was driving. No car in front of me. But a car in the back of me. And it just broke on me. Out of no where. Almost causing the Mercedes Benz to hit me. Luckily they were paying attention. I keep taking it to my mechanic. They are seeing nothing wrong. They don’t want to fix something that’s not...

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.

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...

Fuel pump recall. Put in an order with Honda dealer January 2024 for the pump. On February 2025 asked if they submitted the order back in January 2024? They said it was. Now it's August 2025 (20 months since) and waiting. NHTSA says if they failed to fix in a timely manner to make a report online. Is 20 months long enough? Driving with a safety recall. Second making a complaint with the 10 speed auto transmission 2nd to 3rd hard shift and 4th to 3rd hard shift.
