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.

- Rancho Cordova, CA, USA

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: https://www.driveaccord.net/threads/transmission-issues-2018-honda-accord-2-0t-ex-l.558457/ 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: https://www.motorverso.com/honda-accord-transmission-problems/ 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 groves 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 damages. 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. A youtube explaining the problem: https://www.youtube.com/watch?app=desktop&v=age8_Mi5sEU

- Huntington, CA, USA

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.

- Lakewood, CO, USA

My car ran good up until July 29, 2023. There was a slight tornado and lots of rain when I parked the car it was fine hour later it began to stall and became undriveable. I called my insurance company Progressive and called Honda of Manchester and Progressive had the car towed to Honda. They came back with the diagnosis of my HeadGaskit needs to be replaced my fuel injectors are miss firing and the piston rings needs to be replaced. I have 84,998 miles on the car and all of the maintenance records are up to date. Honda gave me a price of $4,800+ to have it fixed. Where I-??m concerned at is how can these many problems happen at one time and I had know warning signs it just stopped running all of a sudden.

- Manchester , CT, USA

I have been dealing with the check engine light codes p0172c & p219c. Honda inspected my vehicle and said the problem is that my car is running too rich and the fuel injectors are bad but they say i cant really do anything because the fuel injectors are on backorder but really they are discontinued and they are unsure when theyll comeback. Im concerned for my safety and for others on the road because the p219c code is commonly associated with a leaky head gasket, and after speaking to several third party mechanics theyve all said they have been getting others with the same problem and the fuel injector isnt the actual problem, its the head gasket. which means unfortunately my head gasket could blow any moment im driving my car which i NEED to do because i NEED to work. I travel at least 40 miles a day in houston traffic and im very worried about the potential damages i can cause should my head gasket blow while im driving in rush hour on the highway. I had no other kind of warning for this besides the check engine light and its been on for the past 4 weeks.

- Iowa Colony, TX, USA

Engine loss power on and off and start going slow

- Whitestone , NY, USA

Car has approximately 51k miles, beginning to shake, not accelerating as it jerks while attempting to accelerate. Check engine displays but no warnings are available. Comes on and off.

- Coachella, CA, USA

There has been a series of constant issues with this model and each issue has been brought to a certified Honda dealership and was supposedly "fixed" engine code P0300 (random/multiple cylinder misfire),P2651 B rocker arm Actuator system, P0087 Fuel Rail/system pressure, P0304, P0303 cylinder 3 and 4 misfire, engine temperature always above normal. These issues on multiple situations has put my safety and the safety of others at the highest risk. The motor vehicle due to these issues randomly would lose power to the point where stepping on the gas doesn't not accelerate the car, forcing me to stop in the middle of the highway having other vehicles stop suddenly and swerve around me with children in the vehicle. Another occasion going up a hill the car beings to stutter losing power resulting to the car shutting off, forcing me engage These reoccurring issues have also randomly caused the vehicle to not start. Multiple warning signs are lit across the dashboard. These occurrence are random with no warning sign The vehicle has been brought to the same dealership numerous times claiming each issue was fixed but within a few weeks more issues came. The last visit i was told as a "solution" i need to buy a new engine out of pocket, unacceptable for a Honda engine with 64000 miles on it. This oil dilution issue need a proper answer before someone is serious injured.
