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.

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.

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.

2/24/2025 Safety Recall work performed at Honda Marin; change Fuel Pump per recall. 4/28/2025 I reported vehicle stalling/misfiring, decelerating on its own and all lights keep coming on as a result of Fuel Pump change. Marin Honda performed cleaning of battery cables; technician claims nothing is wrong with the car. [XXX] car stalled at intersection, I went back to Honda Marin and reported vehicle is still having the same previous issues and complained that this is dangerous to have the car automatically decelerated on its own. This time I requested only for a diagnostic from Honda Marin. They spoke to my mom, who was not authorized to approve any work on my car, stated no blown head gaskets but mis-firing on cylinder 3, fixed the issue, passed pressure test(s), no leaks; and car was up to factory specks costs $2812.77 charged to my mom. 6/03/2025 brought car back to Honda Marin, same issues; service dept. road tested for 4 miles and stated the car was working as normal. 6/11/2025 told Honda Marin that the car is stalling and misfiring again; car shut down while on freeway; Honda Marin claimed problem was a punctured hose, charged $10.34 car up to factory specks. 6/12/2025 Brought car back to Honda Marin; still misfiring, stalling and dash lights coming on. Car will not accelerate past 3000rpm.; car shut down while in far left land on the [XXX] going to Marin County. Honda Marin performed leaked down test failed cylinder #4; blown head gasket; verbal quote approximately $5500 to fix. In addition to engine failures I had battery issues as well. Per reddit threads others too are having very similar issues, once the fuel pump is replaced, unexpected additional costs and safety failures often occur. This is a Honda Manufacturing Defect, the original fuel pumps are defective, causing a direct impact on the performance of the engine, unexpected damages which is leading to major financial and safety costs to the consumer.

Well to start I had to replace my head gasket already last winter at 59K miles and for awhile now I had warning lights on my dash for CMBS system failure and cruise control/steering wheel controls don-??t work besides the ones for music. No lane assist, none of those safety features work at all and haven-??t for awhile

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.

There are 10 warning lights currently on the dash. This is and has been an ongoing issue for over a year. Turning off the car then turning it back on the lights would go away. The car would periodically start to slow on its own while foot was still on the gas pedal which was dangerous in the middle of traffic or going 65 to 70 miles per hour on a highway. December 31, 2024 my car got towed to the Honda Dealership because the car stalled and wouldn't go past 15 miles per hour. Again the dash lit up. It was my understanding that it was because of the latest recall of the fuel pump issue that took over a year to be completed. The recall of the fuel pump was done January 6, 2025which took a week to complete and a week of work I missed with no available loaner car available to me. Once I got the car back the lights were not on the dash anymore but within 5 minutes of driving the car the lights came back on but the car did not stall and was able to go past the 15 miles per hour that was the original problem. Since January 2025 I have been dealing with these warning indicator lights and being the lights were on when Honda received the car to perform the recall I would assume a diagnosis would have been done but once I got the receipt there was no other issues recorded that was wrong with the car. There are absolutely too many Honda Accords with this problem. I've read everything from moisture in the tail lights triggering the lights, faulty battery, head gaskets, injectors to spark plugs. My car is no longer under a warranty and I have no means of paying for a guessing game when it comes to diagnosing the real problem with these cars. People are paying $5000 sometimes more and still having the same problem once they drive away. I honestly think a recall on this issue need to happen before something tragic happens. Maybe because it took over a year for Honda to get parts in to fix the recall fuel pump issue this is an exact result of going so long with the faulty fuel pump.

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

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.

Dashboard lit up with a lot of lights and stuff

- Mangham, LA, USA

All of the lights in the dash came on. We took it to Honda, at first they said it was the coils and spark plugs. I had them replaced, the same thing happened again the computer read that it was misfiring on one of the cylinders. They kept it and ran several tests. They then tried to say that it the result of a bad oil change but we knew better. After about a month they said that it had over heated and blown the head gasket. I ended up having to use my warranty and pay a deductible.

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 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.
