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 was merging onto the freeway and my car went into limp mode. I was lucky enough to pull over to the side because I was on the far right lane. I took the car to the dealer and was told that the car had blown it's head gasket. How can a 2018 honda accord have blown a head gasket so soon? I looked online and many other 2018 honda owners reported the same issues.

I have a 2018 Honda Accord EX with 104,000 miles. Head gasket blew and coolant is leaking. Upon further research this is a common problem that is now being discovered once the car drives past 60,000 miles. There is an internal memo asking dealers to let them know if they are seeing this too online. Honda has several class action law suits regarding this being a design flaw of the 2018 with the 1.5 liter engine. I spoke with Honda and they offered no assitance, stating out of warranty and no recall. This is their design issue and in my opinion responsible for repairing this. Otherwise out of pocket its a 5k plus repair.

Have had several misfires, nothing would fix it. Dealership looked at it and said the injectors needed to be replaced. Replaced injectors and still had misfire issues. Car is consuming coolant, and there is exhaust is the cooling system. Meaning blown head gasket.

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.

The engine head gasket failed due to design flows. I have to put coolants and oil on a daily basis to keep the car running to avoid overheating.

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 broken also after I did the recall for the fuel pump. Now all these lights pop up on my dash. Driving used to be fun. Now it-??s getting real scary. I am going to go back to the Honda dealer and see what they tell me but I did look up they have to keep fixing it until it-??s fixed. Fingers crossed. I can-??t get another car and I also can-??t keep driving like this. It-??s going to cause an accident.

After having the fuel pump recall completed on my Honda Accord, I began experiencing serious engine problems that I had not had before the recall repair. Shortly afterward, my vehicle developed a blown head gasket, coolant leaking into the engine, and turbo issues. These failures occurred outside of my extended warranty (which has also since expired), but they started only after the recall work was performed. I contacted my dealership and Honda corporate for assistance through a goodwill request, but they denied coverage, stating I am outside of warranty and they cannot determine fault. However, I have since learned that other Honda owners have reported experiencing the same or very similar engine issues after this recall repair. Currently, the vehicle is undriveable without risking complete engine failure. The cost of repair is extremely high, leaving me at a financial loss for a problem I believe is directly related to the manufacturer-??s recall repair.

Blown head gasket at 82,673 miles. Complete loss of power on the interstate traveling 70mph. This was after replacing all the injectors in April at 79065 miles. Same loss of power while attempting to merge into interstate. All maintenance was performed as scheduled.

My car is always having some electrical issue but when I type in my VIN number, no recalls are listed under my VIN number and then for the last couple of days I've been experiencing acceleration problems when I look up a 2018 Honda Accord it is saying that fuel pumps have been an issue, but my VIN number pulls up no information as far as me falling under that recall what are the proper steps to get my car looked at to see if my VIN number Even though it's not populating, any recall falls under the recall

While driving my 2018 Honda Accord Sport 2.0T, I experienced sudden coolant loss and engine overheating. Upon inspection by a mechanic, it was confirmed that the cylinder head is cracked, which is a known issue on the 2.0T engine. This creates a serious safety hazard because it can cause engine failure while driving, loss of power, or even fire risk if coolant mixes with oil. Honda has not issued a recall, but multiple owners have reported this same problem, and I believe it is a manufacturer defect. This should be investigated as it directly affects vehicle safety and reliability. symptoms: Overheating, coolant disappearing, white smoke, loss of power, warning lights, etc.

Blown head gasket
- Hopewell, VA, USA
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.

Car went into Limp mode, immediately brought to a Honda dealership. Planet Honda in NJ. Misfire in cylinder 3. Causation of misfire was a defect head gasket allowing coolant to flow into cylinder 3 causing a vehicle shut down and $3625 in repair costs. Warranty covered it but I have heard many other cases with this have not.

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.

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.
