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.

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.

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.

Hi I just drive my car for about an 1hr and start losing power and a white smoke coming out the muffle I think the head gasket bad.

- Lawrence, MA, USA

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

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.

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.

All lights on head dash are on, all components are not working properly or effected because of this. (Engine light brake light abs light tire light traction control light, sensors out all) while driving vechile reduces power does not operate randomly, have to pull over shut the car off and turn it back on. Has high vibrations lot of shaking, stauling. I have had it looked at with multiple shops and dealer. Everybody is playing a guessing game and can not pin point what exactly it is. Was told it was spark plugs and coils, alternator, fuel injectors. ALL have been repaired, and still have all lights on dash and still facing every problem listed after repairs. Been inspected by manufacturer. Say not been resolved was told if it wasn-??t what was already fixed they don-??t know and that this is very common right now. It first started about a month ago.

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.
