2018 HONDA ACCORD Complaints

On 11/3/25 honda conducted the fuel injection recall fix. Prior to this, no warning lights were displayed on dash. 11/11/25 nine different warnings displayed on dashboard board. 11/13/25 at approximately 35mph the vehicle would not accelerate and the 9 warning notifications continued to flash. Cars had to go around me as I tried to find a safe place to pull to side of the road. I turned off the ignition. I took the vehivle back to the honda dealership maintenance. My vehicle will be there till tomorrow. I was informed code P0304 was present. Prior to recall fix drivability was not a concern and and had no warning lights.

defective turbocharged engine that is prone to overheating, head gasket failure and other problems. Design defect that causes engine coolant to leak into the cylinders

Emission system, low acceleration to the point it becomes a safety hazard in the freeway, I almost got rear ended twice, the car jolts, it stops out of no where, head gasket issues at only 65k. Maintenance was kept up but there’s a Facebook group called Honda sport 2018 to 22 on these models of the same issue “Christmas tree lights”

My car lost power while driving on multiple occasions. My car was originally on the fuel pump recall list but the dealership did not have the part for 6+ months. When the part did come in I found out my car was no longer on the recall list. I had to have my fuel pump injectors replaced due to a faulty fuel pump.

*The engine head gasket- The engine sucked the water from the radiator. *The car overheat in Highway and I had to wait for help to open the radiator to fill it with water *By an independent service center *Not yet- I will take it to a dealer Wednesday the 12th *All the dash lights came up and the next day the temp indicator was going up and down

The head gasket leaked and a piston warped. The symptom was feeling a piston misfire and then the car wouldn't go over 10 miles per hour. Our safety was compromised because we were on a busy (45mph) road and couldn't turn off quickly nor go fast to keep up with traffic. The problem has been reproduced at an independent service center. The vehicle has only been inspected by the mechanic. The previous week all the electrical systems reported a failure. That was repaired by replacing some hose that collapsed on itself. During the misfire, the check engine light flashed, but it didn't before or after (when we were driving very slowly).

Door locks alternate not locking/unlocking with either the door buttons or key fob buttons (battery is good). Available for inspection. Vehicle has not been inspected. No warnings prior. This has happened on and off for about 2 years and now seems like it’s 24/7 a thing with multiple doors at a time now.

I am writing regarding my recently purchased used 2018 Honda Accord. The car has low mileage and initially ran well, but it has developed a recurring cylinder misfire problem. When this happens, the car slows down and cannot exceed 20 mph. This issue has occurred several times—once while my daughter was driving on the highway, creating a dangerous situation as she tried to pull over safely. I took the car to both a Honda dealership and an independent mechanic. The dealership diagnosed a head gasket issue and quoted over $6,000 for repairs. However, the independent shop could not identify the issue—no error codes appeared during their diagnostic scan. After I shared the dealer’s diagnosis, the independent mechanic mentioned that this may be a known design flaw in certain Honda Accords from this model range. From what I’ve learned, the problem involves the engine’s cooling system design. The coolant travels inside the engine around the outside of the cylinders, and Honda used a small channel between cylinders to allow coolant flow. This channel appears to be the failure point, leading to head gasket problems in multiple vehicles. I believe this may be a systemic issue affecting many Honda Accords with this design, and I urge someone from this office to investigate and make Honda take responsibility for these repairs. I am in a position where I am able to transition away from this vehicle, so this will not help me. So I hope you are able to help other, because the repair bill could cripple people and hinder them for using a vehicle that they rely on to provide for themselves and their family.

So about 3 months ago all the sudden all the lights on dash board came on, everyday in the morning when I turn on vehicle on and start driving it does not go over 10 MPH even after pressing gas padel all the way, then I have to shut off vehicle for some time and starts back on it start running but lights still comes on. Honda repair shop told me to change Fuel Injectors which estimate $1,600. But at two different certified mechanic told me Honda Accord has problem with their engine getting coolant in the engine.

I was driving on a highway when a warning popped up about engine temperature being high, advising I avoid heavy acceleration. No other codes came. I parked the car and it sat for about 8 hours. I had a short drive and no warnings came on. I drove on a highway about 30 minutes the next morning and again, no warnings. I was about 2 hours from home. About half way, we stopped for food, still no issues, but when we got on the highway, within about 5 miles warning lights came on about engine temp and the car went into limp mode. I had to have it towed to our loacl honda dealer. They confirmed COOLANT INTRUSION CYLINDER 3 AND 4 CONFIRMING HEAD GASKET FAILURE . Cost setimate was $6063. My car is on;y 6 12 year old, 140,000 miles and has always been maintained.
