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.

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.

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.

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 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.

If car is idling for over 1 minute, all lights on dash come on. When all lights on, car wont wont go over mph, car will randomly sputter in highway when going over 1rpm and will stall randomly. Reported on reddit by multiple people and when I went in to get it diagnosed it was the fuel injector issue

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. Putting stress on other components can break mounts, the transmission, axles, ect. could also launch the car into the car in front of you, in heavy (slow bumper to bumper) traffic. Wasted my own money and time draining and filling 5 quarts of honda 2.0 transmission fluid. (Also replaced the trans filter behind the warmer housing) Did not fix the issue. Contacted American Honda and they said It's out of warranty and I need to pay for diagnostic and repairs. (I just bought the car in 2023 at 45k miles. Previous owner must of felt it and should of did something while under warranty.) Honda know this issue from the beginning and hiding the issue to save money. Check the Accord forums online. It's most of us if not all the 18-20 10 speed models. Vehicle is 2018 Accord 2.0 10 speed 50k miles. Plus the normal Phantom braking and lane departure which will automatically steer you off the road, so you have to fight the steering wheel.

Vehicle had a sudden loss of power. Pulled over on highway had to restart. Engine warning said Emission system problem. Had diagnostic done several codes PO300, PO301, PO302, PO303, PO304, PO172. Problem seems to be similar to the service bulletin 22-002 dated Feb 18,22 for the Honda Accord 2015-2016. It seems to be a known issue with this engine. Honda should take care of this safety issue.

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.

Vibration in car took it to dealership but still can't figure out what's causing to vibrate so much when driving and idling.

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.

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.

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.

- Clarkston , MI, USA

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
