ENGINE
The car misfires very badly. I have changed the fuel injectors, fuel pump, spark plugs and the ignition coils to no avail. Also, car randomly showed to be overheating one day, got home and checked and my coolant level had dropped dramatically very quickly. The car has since been diagnosed with a bad head gasket.

I was driving and the engine light started flashing, the car started to hesitate and would not go over 20 mph. I took it to the Honda dealership in Frisco, TX and they diagnosed the issue using Boroscope and recommended Head Gasket replacement with spark plugs due to plugs being fouled from coolant leaking into combustion chamber.

FUEL/PROPULSION SYSTEM
On June 13, 2025, the fuel pump was replaced due to a recall. After the fuel pump was replaced and, in particular, after reading the Honda forums for this car, all the warning lights in the instrument cluster came on. After my mechanic checked my car and, with his knowledge of this type of vehicle, he recommended replacing the fuel injectors at 86,000 miles. Honda recommends replacing the fuel injectors at 1000 k. In the forums, this is what owners of the 2018 Honda Accord are doing.

This car has a faulty motor that Honda is well aware of. The head gaskets crack, and the antifreeze leaks into the cylinder. Specifically, Cylinder 3. My car is at the dealership, and the repairs are 6500. They refuse to acknowledge this problem and currently have a class action lawsuit because of this very issue. I need a car because I am a full-time student.

FUEL/PROPULSION SYSTEM
I am reporting a failed remedy for Recall 24-009 (23V-858). Following the fuel pump recall, my 2018 Accord stalled in traffic on March 21. On March 24 upon starting my vehicle all warning lights were illuminated on the dashboard, Millennium Honda admitted the O-ring was misinstalled. This error triggered codes P0172/P0176 less than twenty-four hours later. The dealer is forcing me to pay $425 for damage caused by their botched recall repair.

ENGINE AND ENGINE COOLING
The contact owns a 2018 Honda Accord. The contact stated that the engine overheated while parked, with the message "Engine Temperature too High - Do not Drive - Allow Engine to Cool Down" was displayed. The vehicle was taken to two independent mechanics, where the spark plugs and battery were replaced, however, the failure persisted. The vehicle was then taken to a local dealer, where it was diagnosed with head gasket failure. The manufacturer was notified of the failure. The approximate failure mileage was 96,500.

FUEL/PROPULSION SYSTEM, ENGINE, VEHICLE SPEED CONTROL
I started driving this vehicle and all of a sudden it started slowing down, and would not go up to speed. I had it fixed, the car started skipping, making a jerking movement while driving. I made an appointment with Tameron Honda of Birmingham on 3/26/26. As soon as I pulled up to Honda dealership the engine light was on. The company was trying to bill me 6100 dollars for fixing the car. I do not have that amount on hand and I need my car. I had to drive my car away from the dealership while it was in idle mode state into traffic the car moved so slowly that I could have wrecked. The dealership did not do their due diligence by going off of the vin number and making sure that the customer is safe with their brand. I was told that they did a full inspection at the dealership. I have been scared to drive this vehicle since the issue keeps happening.

As soon as I got to work and put it in park I got a message on the dashboard saying “Engine Temperature Too Hot. Do Not Drive. Allow Engine To Cool”. No other warning signs were shown before this. I looked up on google what maybe it meant and to my findings it mentioned gasket and all I noticed recent complaints and claims filed with 2018 Honda accords for a known issue with these Honda accord sport 2018 models for blows gaskets.

SERVICE BRAKES, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING
I own a 2018 Honda Accord equipped with Collision Mitigation Braking System (CMBS). The vehicle has experienced multiple instances of false collision warnings and phantom braking. The issue occasionally occurs when approaching overhead interstate signs. In most cases, the system flashes brake warnings briefly and then clears. However, on one occasion during rainy conditions a few years ago, the vehicle unexpectedly applied the brakes at highway speed with no obstacle present. The vehicle has undergone multiple camera calibrations (this may have also included the radar), but the problem persists. This creates a serious safety hazard, particularly at highway speeds where sudden braking could result in a rear-end collision. The issue appears to be related to false object detection by the ADAS system, potentially involving radar or sensor misinterpretation.

Almost all of the 1.5T engines (L15BE) are having head gasket issue where the gasket slowly fails over time resulting in slow coolant loss and at one point sudden overheating causing block and head warping die to design flaw ( groove in between the cylinders resulting in lack of effective and enough surface area for the head gasket to seal the combustion chambers). It has been confirmed by Honda techs and by average 100k to 140k, all engines are failing and the dealers are raking up $ 6k to 9k charge for each change or even having to need new engines half the time. This process of slow leak results in sudden loss of power at highway speeds or acceleration and causing extreme danger of getting hit and having accidents. Took vehicle to mechanic and confirmed coolant leak inside cylinder 4 and 3.

Major head gasket failure with no warning while pulling out onto a busy road. There is a major design flaw with the head gasket, no recalls or preventative notices from Honda whatsoever! My wife was put into a dangerous situation once the car went to limp mode with no warning while getting onto a busy road. Multiple lights on the dash lit up when the car entered limp mode. The car was immediately towed to a Honda dealership and was diagnosed with a blown head gasket. Service manager stated this is a VERY common occurrence and is indeed a design flaw. Car was fixed with no help from Honda for their faulty design $5100...

UNKNOWN OR OTHER
The AC system on my 2018 Honda Accord 2.0T stopped blowing cold air due to refrigerant leaks in both the AC condenser and AC evaporator. The condenser is covered under Honda's warranty extension (Service Bulletin 21-018) which acknowledges a manufacturing defect where R-1234yf refrigerant corrodes the condenser tube walls. The dealer confirmed the evaporator is also leaking from the same corrosion defect. The dealer states both must be repaired together because the system cannot hold refrigerant with a leaking evaporator. Honda corporate is refusing to cover the evaporator repair despite it being caused by the same known manufacturing defect. This is a systemic issue affecting 2018-2020 Accords and other Honda models using the same AC components and R-1234yf refrigerant.

Head gasket had to be changed out. I have seen multiple cars having the same issue with this model. The vehicle sputtered and would not let me drive above 40mph. It was a safety issue when I first had it and it occurred in the freeway.

While driving at highway speed, the engine suddenly stalled without warning, resulting in a complete loss of power. This created a dangerous situation as I was unable to maintain speed or safely maneuver with surrounding traffic. At the time of the incident, all electrical warning lights illuminated on the dashboard simultaneously. Prior to this event, there were no clear warnings indicating imminent failure. The vehicle was later diagnosed with a failed head gasket and turbocharger issues. The sudden engine stall while in motion presents a serious safety risk, particularly at highway speeds, as it increases the likelihood of a crash due to loss of propulsion and reduced driver control. This issue appears to have occurred unexpectedly and without adequate warning
