I was on the highway with moderate traffic. My car would no longer accelerate due to a blown head gasket out of nowhere, I was on the far left lane and had to traverse over 5 lanes in moderate traffic while other drivers on the highway were going 60+ mph. This is a common issue among Honda Accords with the 1.5 engines.

Hi, I would like to address two issues separately for my 2018 Honda Accord 1.5T 6MT; one dealing with the open recall and one dealing with how the vehicle operates dangerously due to poor programming under specific operating conditions. To add, I speak as an engineer working in the automotive space specifically on the design of ADAS and AV systems with ISO26262 and SOTIF in mind. 1) There is an open recall for my vehicle for a fuel pump issue. I am experiencing some of the symptoms of this issue, specifically, my car will hesitate at around 4000 RPMs during acceleration. I immediately back off the accelerator and then the check engine light flashes and I lose all engine power. I then restart my vehicle and it operates more or less normally with the occasional illumination of all the dash lights. I have taken my car to the dealership expressing my concerns (Braman Honda of Palm Beach in particular) and they said they cannot do anything about it unless since there are no parts. I have paid for them to diagnose the issue but since they cannot recreate the issue (as it is intermittent) they cannot do anything. Question: what is the point of a recall if a vehicle experiencing the symptoms that lead to the recall cannot be repaired due to "part shortages"? 2) I want to talk specifically of the vehicle programming to cut engine power off. I think I have a separate electrical issue that causes all the lights on the dashboard to go off and again cut engine power. I understand that engineers may want to design their vehicles to cut power off when there is a potential mechanical failure, but in this case the issue is purely electrical. The fact that I can restart my car and accelerate normally shows that the issue is not mechanical. I believe this programming needs to be addressed. To be frank, losing engine power while driving on the highway may lead to catastrophic consequences. I feel that my vehicle is unsafe to drive since it has happened to me multiple times already.

While taking off from a full stop, the vehicle's transmission shifted violently to the point where it felt as if the car was rear-ended. This is an issue for which I've filed numerous complaints before with NHTSA knowing about the problem by now, and having done nothing to initiate a recall. I have also taken the car to the dealer who failed to properly diagnose the issue. Finally, another mechanic did provide me with an entry from Honda where they sort of admit to the issue. The fix, of course, is to replace the valve body or the whole transmission. Hence, due to NHTSA sitting on their thumbs, thousands (maybe, hundreds of thousands) are now stuck with a vehicle which will need a multi-thousand dollar repair outside the warranty and NHTSA did not properly investigate the issue and push the manufacture to issue a recall.

Numerous Honda Accord 1.5T have blown head gaskets, numerous complaints of this happening during freeway travel. The car will suddenly go into a "limp mode" and won't let you travel over 20mph. This could cause an accident. Numerous examples of this can be found on YouTube, Facebook, Reddit, and other social media outlets. Honda Service Techs explained this happens because of weak head bolts that stretch overtime due to pre detonation. most commonly accruing between 20,000-75,000 miles. No recall, extended warranty, or TSB has been issued by Honda, often leaving the owner with a bill between $5000-$10,000.

I was attempting to accelerate on the acceleration ramp to merge into traffic on the interstate, when my vehicle began violently jerking, and suddenly lost all power. My check engine light came on and it went into limp mode. This has happened twice now. Both times I was able to make it safely into the shoulder of the road with my hazard lights on. I turned the vehicle off, reset it, and have had to drive it since. The warning lights are on and off, depending. They-??ve had since December of 2023 to release a recall and they haven-??t yet. I need a remedy.

These Accords are an extreme safety hazzard. Experienced an instant loss of power and without any prior warning signs. Once the issue accured the vehicle was impossible to drive putting the vehicle occupants and everyone on the road at risk. Now Honda does not want to fix the problem because they feel that would be an admission of guilt. This is not the first I've heard of this issue with these vehicles and I'm sure it will not be the last please help push these vehicles for a safety recall before more people get hurt.

My 2018 Honda Accord 1.5 turbo (original owner) 77,000 miles. Started having numerous warning lights on dash and vehicle was violently shaken. On several occasions, vehicle had no acceleration over 10mph which caused me to have several close calls on the highway. Took it to Honda dealer and they stated that I had a blown head gasket and the repairs would cost five thousand eight hundred dollars! Unfortunately i have read numerous posts on Honda forums and hundreds of customers with the same vehicle year and model are also reporting the same problems. Honda will not pay for any repairs since it is past warranty. This needs to be upgraded to a recall by Honda, very upset customer!

I got a blown head gasket to cynlinder #3 at under 100k miles. I maintain it regularly as needed by use of the maintenance minder. Never got any indication of engine troubles before. On doing some research this seems to be a common problem for this make and model and seems to be a possible defect. The repair was $4300 to repair the head gasket.

All warning systems triggered, repeatedly, over the past year. Honda dealership misdiagnosed as a fuel injector. Had fuel injector replaced, but same issue occurred and this time all warnings came on and vehicle lost power on highway with my baby daughter inside. So, after spending thousands attempting to resolve the issue, I towed again to Honda and it was correctly diagnosed as a failed head gasket requiring $5.5K to repair. Service advisor said he's seen "many of these" recently. Called around Tampa and all mechanics advise (consistent with numerous complaints online car communities) failed head gasket is a known and common safety issue (to the extent that parts are on backorder as a result of repairs). Called American Honda Corporation and they led me to believe they would repair, but after an hour of wasting my time, and repeated requests to hold so agent could speak with supervisor, agent then said repeatedly "there is nothing we can do for you." This abject safety failure and demonstrated bad faith should not be allowed by regulators who have a duty to mandate that auto manufacturers do the right thing and issue safety recalls for known issues such as the head gasket failure I have experienced.

The contact owns a 2018 Honda Accord. The contact received notification of NHTSA Campaign Number: 23V858000 (Fuel System, Gasoline) however, the part to do the recall repair was not yet available. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The contact stated that while driving at an undisclosed speed, the accelerator pedal was depressed; however, the vehicle did not accelerate as intended. In addition, the vehicle lost motive power. The contact also stated that as the failure continued, several unknown warning lights illuminated. The vehicle was taken to the dealer; however, the failure could not be duplicated. The contact was advised to have the transmission flushed. The transmission fluid was flushed; however, the failure reoccurred. The dealer was made aware of the failure but confirmed that parts were not yet available. The vehicle was not repaired. The manufacturer was made aware of the failure. The failure mileage was approximately 57,000. Parts distribution disconnect.

To whom it may concern, I understand there is an investigation on leaking timing chain/pully cover. My vehicle has this issue. Is it covered by a recall? Please advise.

I have a 2018 Honda Accord 1.5t Sport. It has 113,000 miles on it. And I took it in for a diagnosis due to an inspection made by Walmart and I was told by the Honda dealership I have a blown head gasket. After much research and discovery, I found out this is a common and typical issue with this model car and that Honda corporation knows about it but refuses to issue a recall. I never experienced any warnings, car never ran hot or overheated. There was never any indication that the head gasket was an issue. Now that they have determined this, they are telling me because it is out of warranty it will not be covered and I am responsible for the $3000 charge to fix the head gasket. This is very upsetting being that Honda is very aware of the situation and seem to care less about the safety of their vehicle owners and the terrible situation that this puts their customers in.

The contact owns a 2018 Honda Accord. The contact stated while driving at an undisclosed speed, the vehicle started vibrating violently. The vehicle then lost motive power and was unable to accelerate above 10 MPH. The check engine warning light was illuminated. The vehicle was taken to an independent mechanic, who determined there was a misfire in cylinder #3. The vehicle was repaired, but the failure reoccurred. The manufacturer was notified of the failure, and a case was opened. The failure mileage was 77,000.

Fuel pump or injector has malfunctioned. It is has already been inspected by a Honda dealer. Safety at risk because there was a recall on the fuel system of Hondas in 2020. I purchased this vehicle in 2021 and was not made aware. The vehicle could stall and cause an accident. No other problem currently reported on the vehicle. I was just sitting in a parking space when the engine light came on.

Intermittently, the vehicle has a very violent shift at low speed (under 20 miles per hour). In the past, this had been mentioned to the dealer, numerous times, who claimed that the issue is not reproducible. However, during the visit on 12/06/2022, dealer mechanic(s) claimed that they did witness the issue and performed the following (per dealer's notes): "reset TCM and Batter cable reset." After which (the dealer notes state): "Let the customer know that the trans will adapt to driving habits within 200 miles. If the customer drives hard, the transmission will learn hard to shift hard etc..." The second statement is nonsensical, since, most of the time the transmission shifts relatively fine, regardless of the driving pattern (i.e. hard, mellow, etc.) and the issue happens intermittently (every so many hundreds miles driven), at very low speeds with very little accelerator input, which indicates more of a software issue (and, possibly a mechanical design defect, coupled with the SW issue). There are now other customers with, what sound like, a very similar problem: [XXX] Just as with my vehicle, other dealers are claiming "there is no issue" and Honda has ignored the issues. Honda has a history of transmission problems from the 2000s and it's really worrying that they might be repeating that pattern with 2018-on models: [XXX] While I am noting the issue at this mileage, there are numerous other instances of where the same problem occurred: at 46888, 47062, 47198, 47473, 47525, 47647, 52427, 52433 (so back to back), 52564, 53655, 53723 miles. At around 53494 mi had the car checked again by the dealer, who claimed no issue this time. The violent manner in which these shifts happen, makes one wonder how much mechanical damage is being done to the transmission and if a recall should be issued.

My car is barely at 78,000 miles and I use premium gas, and get oil changes regularly but my car all of a sudden started having a cylinder 4 misfire. Thought it was just my spark plugs having to be changed, but after changing my car was still running rough and still misfired. There is a manufacturing defect for this model where the turbo is too strong for the engine and factory head gasket. There are grooves on the engine block for cooling but the turbo causes too much pressure and then air is creating too much space with the head gasket that can lead to it blowing. A blown head gasket repair is $1,500-$5,000 a repair or having to replace the whole motor if it gets too damaged. There are many examples of this problem on tons of honda accord forums having the same problem around this same mileage. For the images the crease in the engine block is supposed to be for cooling but it part of the root of the problem and the head studs are not strong enough.

All warning lights came on and I took the car to get checked out. Head gasket is damaged. Honda dealership has performed all service on vehicle. Gasket shows signs of premature deterioration. Very expensive repair for a know problem. This should be a recall item as there are numerous complaints with this model.

The vehicle had a very violent shift (perhaps it was turbo lag related?) at low speed (under 20 miles per hour - typically, this happens in a parking lot or the like as you slowly drive away). In the past, this had been mentioned to the dealer, numerous times, who claimed that the issue is not reproducible. However, during the visit on 12/06/2022, dealer mechanic(s) claimed that they did witness the issue and the fix the performed the following (per dealer's notes): "reset TCM and Batter cable reset." after which (the dealer notes state): "Let the customer know that the trans will adapt to driving habits within 200 miles.
