ELECTRICAL SYSTEM, ENGINE
Head Gasket caused multiple issues with coolant burning quickly. Multiple ignition coils also got damaged and had to be replaced. Though the underlying issue with the gasket was not addressed by the dealership. The head gasket is currently broken and does not function at all and the car has only driven 84000 miles.

ELECTRICAL SYSTEM, ENGINE, UNKNOWN OR OTHER
A 2018 Honda Accord suddenly displayed multiple dashboard warning messages at the same time after previously operating normally. The warnings include: Emission System Problem (avoid heavy acceleration), Tire Pressure Monitoring System (TPMS) problem, Brake System problem, Brake Hold System problem, Electric Power Steering system problem, Vehicle Stability Assist problem, Hill Start Assist problem, Adaptive Cruise Control system problem, Collision Mitigation Braking System problem, and Road Departure Mitigation System problem. These alerts appeared simultaneously when the vehicle was started, even though the car had been driven the night before without any issues. The vehicle still starts and runs, but the number of system warnings suggests a possible electrical, sensor, or control module issue affecting multiple vehicle systems.

There are many warming lamps on in the car. My car won't pick up speed it in limp mode once I crank up. I have to turn it off and restart any order for it to go and pick up speed. My number 3 plug keep showing something wrong it has been replaced multiple times but still having the same issue. I had it checked out it's saying the same problem fuel. I have had my fuel pump change and still having problems. 2018 are bad models for honda and there should be multiple recalls because everyone having the same problems.

ENGINE
Wastegate actuator is no longer working and turbo on vehicle is no longer working as needed. My car currently has every warning light on the dashboard and fails to provide all advanced driver assistance systems that come with my vehicle making it unsafe. The problem has been addressed by Honda dealership service themselves as my code came back that it is a turbocharger wastegate sensor issue. Car has not been inspected by a manufacturer, police, insurance. All warning lights went off on car over two years ago from 2026.

POWER TRAIN
My Honda is shifting harsh going into 5th gear and sometimes reverse is not available. I have taken the vehicle to the dealership and they are telling me I need a new transmission to the tune of $9,600. It only has 64,000 miles and the warranty recently expired. I took the car to another mechanic and he told me the same thing. There is no way that the transmission should go out at such low miles. Honda needs to step up and take care of this problem. There are many complaints about this issue but nothing is being done. I have the 7 year/100,00 mile warrany but the car is a 2018. This was the first year of the 10-speed transmission and many people are having problems. This needs to be addressed.

POWER TRAIN, ENGINE
On February 26, 2025 I was driving my 2018 Honda Accord Sport (118,000 miles) with a 1.5t engine on a 55mph 2 lane roadway at approximately 55mph with 4-5 cars behind me when the engine suddenly went into "limp" mode and quickly decelerated to approximately 25 mph. I could see the cars behind me suddenly brake to avoid hitting me. I pull off on the shoulder, turned my car off and restarted. The car then drove normally to home. I took the car to the Honda dealer who diagnosed a blown head gasket. The sudden deceleration was caused by a misfire due to coolant entering the combustion chamber during the combustion cycle. The sudden deceleration almost caused an accident. When this happens the Accord does not warn the drivers behind with brake lights or flashers. I had the head gasket replaced at a cost of $4000+ The dealer's mechanic believes the cause is improper head bolt torque specs at the factory. Honda is aware of the a head gasket problem with the 2018-2020 Accord 1.5t engine, see Honda's NHTSA filings attached offering visa cards to mechanics who report head gasket failures, yet refuses to recall the engine or pay for replacing the head gasket unless under warranty. This is my 4th Accord (1985, 1986, 2007, 2018). I have never had any engine problems with my other three Accords. Honda needs to recall this engine and correct the head gasket problem so as to avoid unannounced, uncontrolled, and unintended deceleration at highway speeds due to going into limp mode (70-75 mph on interstates down to 25 mph) that can cause following cars to crash into the Accord. I purchased the car with 22,000 miles on the odometer and performed regular maintenance since I purchased it.

ENGINE, FUEL/PROPULSION SYSTEM, ELECTRICAL SYSTEM
It appears to be either the fuel pump or fuel injectors, at certain times of acceleration the car stops accelerating, the engine light blinks, I have to shut the car off and restart it. It seems like if I slow my car down then try to accelerate, like going through a roundabout or sitting in stop and go traffic really seems to set the problem off. I took it to a Honda dealership a couple years ago and they informed me it was fuel injectors but they were not in stock, they assured me the car was fine to drive, I called a couple times to ask if they had gotten the part, they sternly told me they would call me, anyways they never called me and it still happens, there is a recall out for other 2018 Honda Accords that seem to have a similar problem. All my lights are constantly on due to this problem, none of the features on my car work. Sometimes if I reset my battery the lights are fine for a while but the problem still persists. If I "Rev" my car up and gas it pretty hard when I immediately start driving it seems to help.

ENGINE, ELECTRICAL SYSTEM, FUEL/PROPULSION SYSTEM
The high-pressure fuel pump on my 2018 Honda Accord failed even though the vehicle had previously been repaired under a recall for the same issue. While driving, multiple warning lights illuminated on the dashboard, including the check engine light and other system warnings. The vehicle began running rough and lost power, creating a dangerous driving condition, especially in traffic. This is the second occurrence of fuel system failure despite the recall repair being completed. The recurrence of this issue raises serious safety concerns, as sudden power loss or engine malfunction while driving increases the risk of an accident. The vehicle is currently not safe to drive due to the risk of stalling or loss of power. The problem appears to be related to the high-pressure fuel pump system that was previously addressed under recall.

I was driving on the interstate and suddenly I could no longer accelerate, my engine light started blinking and I had to pull over to a gas station as my car would not go above 25-30mph. I turned it off and back on and it work so I took it home. I took it to Honda’s the next day and after diagnosis they said that my head gasket was damaged causing coolant leaking into my engine cylinder and warping of the engine. They recommended an engine replacement. I never had any warning indications on my dashboard until then. I filed a case with American Honda to assist with repairs and it has been over two weeks without resolution. I no longer felt safe continuing to drive my car and I traded my car in for safety.

UNKNOWN OR OTHER
I wanted to report that this vehicle, according to Carfax, had 169,236 miles on August 15, 2025, and 9/4/25, and 85,326 miles on January 24, 2026. That's only 4 months! The odometer was tampered with, and this seller knew it was altered because it went through 5 different sellers in those 4 months. I don't know if their reports are true or false, which is why I'm writing to see if you can help me.

The contact owns a 2018 Honda Accord. The contact stated that one of the tires was punctured by a nail, and after the tire was replaced, the check engine warning light and other unknown warning lights illuminated. The vehicle was taken to an Auto Zone, where it was diagnosed, and determined that there was a misfire in cylinder #2. The vehicle was then taken to a certified mechanic who replaced the cylinder, engine, ignition coil, and spark plug. After the vehicle was repaired, it was returned to Auto Zone to be diagnosed again. The contact was informed that there was a misfire in cylinder #2. The vehicle was returned to the mechanic, and it was confirmed that the spark plug in cylinder #2 was new. The contact continued driving the vehicle; however, a month later, several warning lights illuminated. The vehicle was taken to the dealer and was diagnosed with a misfire in cylinder #2. The dealer recommended replacing the fuel injectors and that an alignment of the radar was needed, and there was a failure with the transmission fluid, the CVT, and a software failure. The vehicle was not repaired. The vehicle was previously included in a recall for the failure; however, the recall repair was already performed. The manufacturer was not made aware of the failure. The failure mileage was unknown.
