Prior to blown head gasket vehicle was brought to Honda in April 2025 for overheating, rough start and leaking coolant and was told fuel pump had a recall so it was changed, Honda did the recall repairs, performed oil change and checked everything else and released the car in working order but a week later after adding 175 miles more to the car it started overheating and had a rough start, the car was immediately brought back to Honda and they said it was a blown head gasket, the car was driven home that same day and left in the driveway undriven until September 3rd 2025 when it was towed to a different Honda dealership where it was confirmed to be blown head gasket and the cost is estimated at $6800 to repair. The car has had all recall issues addressed as well as all service and oil changes done to the vehicle, the car is driven for leisure and never in an unsafe or harmful way that could damage a head gasket.

Engine overheating due to coolant leaking and car needing head gasket replacement Fuel injectors also failed

On the morning of July 26, 2025, while returning home from a grocery shopping trip, my vehicle experienced a sudden and severe loss of power while traveling on an interstate highway with a posted speed limit of 65 mph. Without warning, the car ceased to accelerate and began to decelerate rapidly. I immediately activated my hazard lights and attempted to locate a safe area to stop. Vehicles traveling behind and alongside me were forced to brake abruptly to avoid a collision. Fortunately, no accident occurred, though the situation clearly presented a significant risk of one. After pulling onto the shoulder, I turned the vehicle off and restarted it. It initially appeared to operate normally, allowing me to resume driving. However, within a few minutes, the loss-of-power incident occurred again. I managed to pull over a second time, restart the vehicle, and continue the approximately 10-minute drive home without further incident. Upon taking the car to my mechanic, I was informed that coolant was present in one of the cylinders, indicating a failed head gasket. The mechanic advised that I bring the vehicle to an authorized Honda dealership for repair. The Honda service department performed diagnostics and confirmed the head gasket failure. The repair cost was $3,758, which I paid in full. Subsequent research revealed that this appears to be a widespread issue affecting certain Honda models manufactured between 2018 and 2022. I discovered numerous consumer complaints online and learned that a class action lawsuit has been filed regarding this exact defect. Based on my understanding, head gasket failures are uncommon—particularly in vehicles with relatively low mileage. My vehicle has approximately 83,000 miles on it. While I am dissatisfied with the substantial financial burden of this repair, my greater concern lies with the serious safety risk posed by the sudden loss of power at highway speeds. I respectfully request that this matter be reviewed.

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.

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

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.

Head gasket between cylinders 2 and 3 blown, despite regular maintenance being completed by Honda dealerships. This issue has caused vehicle to go into "limp mode" while on the highway leading to safety concerns. This problem has been confirmed by not only a Honda dealer repair shop but also an independent repair shop and owners. There were not warning prior to the failure. Per the dealership, this is not something that could be caught during regular maintenance and inspections.

Car had a rough start one morning. The engine light came on. All safety features were disabled. I took it to the car dealership that same day (sunset Honda San Luis Obispo California) they got back to me and said the car had head gasket failure. The dealership was the only person to do any meaningful mechanical work ( I did the oil changes) including transmission fluid and coolant changes spark plugs, belt sand valve adjustments etc. car is driven lightly as a daily commuter for work

The contact owns a 2018 Honda Accord. The contact stated that while driving at an undisclosed speed, several unknown warning lights illuminated, prompting the contact to pull over to the shoulder of the roadway where the failure persisted. The vehicle was taken to the dealer, who diagnosed a failure with the head gasket, resulting in a misfire in cylinder #3. The contact was informed that the head gasket needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure, a case was opened for a goodwill assistance claim, and the contact was referred to the NHTSA Hotline for assistance. The contact was later informed that the goodwill assistance request was denied due to a lack of service records with a Honda dealer. The failure mileage was 74,000. The VIN was not available.

Engine malfunction. Goes into “limp mode” going over 1800 RPM. Dealer has replaced engine coils and plugs multiple times. Sold as Honda True Used with warranty. Dealer states it’s out of warranty.

The head gasket on my car blew before 150,000 miles. I had my car repeatedly serviced to include the recall for the fuel tank. I had to replace fuel injectors in a head gasket on this vehicle.

I was driving the car and it stopped working the car was just rolling, it lost speed in the road! All the warning lights were displaying, including the engine light. I took this car in to have a dynastic test at the Honda dealership. They reported it was the head gaskets. I’m very disappointed and don’t have the extra money for experience repairs.

I was driving on a highway when a warning popped up about engine temperature being high, advising I avoid heavy acceleration. No other codes came. I parked the car and it sat for about 8 hours. I had a short drive and no warnings came on. I drove on a highway about 30 minutes the next morning and again, no warnings. I was about 2 hours from home. About half way, we stopped for food, still no issues, but when we got on the highway, within about 5 miles warning lights came on about engine temp and the car went into limp mode. I had to have it towed to our loacl honda dealer. They confirmed COOLANT INTRUSION CYLINDER 3 AND 4 CONFIRMING HEAD GASKET FAILURE . Cost setimate was $6063. My car is on;y 6 12 year old, 140,000 miles and has always been maintained.

While driving the car, the oil light came on and the engine died. Losing vehicle power while driving poses a very serious safety risk. After taking it to a Honda dealership, the mechanic diagnosed the following issue: "head gasket has failed causing coolant to leak into Cylinder 3".

I went to enter the highway and the car would not accelerate and the check engine light was flashing and went into a limp mode. I got it looked at it it was giving me the misfire code for cylinder 2. I paid over $1k and had all the spark plugs replaced and coils. It was fine and then 6 days later it happened again. The mechanic looked at it pressurized with the bore scope and saw coolant. Then we knew it was the head gasket. This is crazy especially with Hondas being known for reliability. I’m at 87k miles and have been seeing that this happening to many others.

Faulty head gasket that resulted to more engine problems

I own a 2018 Honda Accord (1.5L Turbo Engine) and I have kept regular maintenance on the vehicle. I currently have 146,600 miles on the vehicle. I begin having problems last year as I was leaving work and my vehicle wouldn't start. I waited a few minutes for the vehicle to start and it started and several malfunction lights came on the dash including the engine light. I had a 30 minute drive home and as I was driving home the vehicle didn't want to pick up speed to the speed limit of 65. I drove slowly home. I had already made an appt with the Honda Dealership where I get my car serviced for an oil change a couple days before. The next day I had a family member to follow me 30 minutes away to the dealership to drop my car off. When I dropped the car off I told the service technician about the problem. Later that day the dealership's service department called to tell me that I my head gasket had blown and it would be around $4500.00 to repair. I began to ask questions as to how this could happen I had kept up with regular maintenance. The service technician begin to tell me different reasons, and I asked how when I had regular maintenance and some suggested maintenance required as well. I had my vehicle towed from the dealership to get a second opinion. The technician I took my vehicle to was authorized to work on Honda vehicles, and he asked me if I was aware of the complaints customers were having about their Honda 2018 (same model) was having about leaking coolant, cracked or blown head gaskets on cylinder 3. I told him I was not aware so I went and did research and found there were numerous complaints about the same problem I am having and Honda was not acknowledging the problem or people had the repair done which cost a couple thousand dollars only to have their cars still not working properly or getting the same malfunction lights. Now I have to look for another car. Honda's are supposed to last.

The Head Gasket is leaking at 135k miles after changing oil and filter every 5k miles and flushing coolant every 50k. Just a cursory internet search will show you how obvious the design defect is in the head bolts of the 1.5 liter turbo engine and they should be recalled.

The contact owns a 2018 Honda Accord. The contact received notification of an unknown recall. The contact stated that while driving at various speeds on several occasions, the check engine warning light blinked, and the vehicle lost power. The vehicle was restarted after each failure. The vehicle was not diagnosed or repaired. The manufacturer was not notified of the failure. The failure mileage was unknown.

Head gasket caused by 1/4 inch head bolts and torqued to 50 lbs multiple people have filed a class action lawsuit regarding this and it’s affecting most Hondas with a 1.5L engine. It caused misfiring and jerking it was inspected and confirmed by Honda service center that my head gasket was blown and I had purchased the car 12k miles ago.

While driving my 2018 Honda Accord, the engine began running roughly and the check engine lights and multiple warning lights came on. The vehicle was taken to a Honda dealership for diagnosis. The service department informed me that coolant was leaking into the engine, causing damage to the head gasket and cylinders 2 and 3. They confirmed this issue and recommended either an expensive head gasket/cylinder repair or a full engine replacement. Prior to this failure, I occasionally noticed mild engine hesitation, but no specific warning messages about low coolant or overheating appeared until the check engine light activated. The dealership stated this is not an uncommon issue with this engine. Upon further research, I discovered many other 2018 Accord owners with the same 1.5L turbocharged engine have reported coolant intrusion, cylinder damage, and head gasket failures — often affecting cylinders 2 and 3 specifically. This appears to be a design or manufacturing defect in the engine. This type of failure poses a safety risk due to potential engine misfires, power loss, or stalling while driving. The problem was confirmed by a licensed Honda service center, and I believe this issue should be investigated further for potential recall or manufacturer accountability.
