2018 HONDA ACCORD Complaints

While driving the car it went in to limp mode, restricting the ability to maintain normal driving. It did this because the head gasket needs to replaced because coolant is leaking into # 3 cylinder. My wife and others were put at risk when she had to pull over in an area that was unsafe according to a Summerville police officer who came to her aid and helped her get the car to a safe area.

The contact owns a 2018 Honda Accord. The contact stated that while driving the vehicle she noticed a power issue with the vehicle, thinking it had to do with the battery, the vehicle was misfiring. The vehicle was towed three times to the dealer, where it was diagnosed with a engine failure. The second tow was to a independent mechanic, and the third time the vehicle was taken to a dealer where it was diagnosed to have a engine gasket failure. The contact was informed that there was a coolant intrusion in cylinder #2. The contact was informed that the head gasket needed to be replaced. The vehicle was repaired. The vehicle was not repaired. The manufacturer was not made aware of the failure. The failure mileage was 73,000.

The head gasket malfunctioned/ broke. It has been confirmed by the Honda dealer where I currently have my vehicle. There were no messages or symptoms prior to failure. My safety and others were put at risk because my vehicle began to turn off as I was driving up a hill with no warning. The vehicle began to decelerate.

Vehicle: 2018 Honda Accord On [XXX], at approximately [XXX] PM, I was driving on [XXX] [XXX] at approximately 35 mph. The weather was clear and the road was dry. A vehicle ahead of me began turning into [XXX] N. My vehicle’s Collision Mitigation Braking System / automatic emergency braking system activated suddenly. The system made an audible warning sound, displayed a warning icon, and applied braking even though I did not believe there was a crash-imminent situation. There were vehicles behind me at the time, so the unexpected braking created a potential rear-end collision risk. The braking event also caused back pain, and I later experienced some stomach discomfort. I am concerned this was a false activation of the automatic emergency braking / Collision Mitigation Braking System. I am also concerned because the system reactivates after the vehicle is restarted, meaning I cannot reliably prevent another unexpected braking event from occurring. I am requesting that this be documented as a vehicle safety concern involving possible false activation of the automatic emergency braking system.

While driving vehicle detected both road departure and engaged the emergency automated braking. The vehicle attempted to correct the "road departure" by steering the vehicle away from the perceived problem and engaged the brakes nearly causing a collision as it has done numerous times before. I have reported this to NHTSA and American Honda multiple times and await a repair of this dangerous issue. Honda has opened a case on this but have had 18 months and no response has been issued.

Car was failing in 2024 due to fuel recall. It was fixed by Webbs auto shop. Now 2026 recall shows with DMV and Honda is failing at providing a proof of correction after Inspecting the car and approving all the changes made to it. I am unable to get my car tags due to Honda failing to comply with what DMV is needing to complete this request for my tags.

The head gasket was blown on highway even though the car was functioning perfectly fine and was well maintained.

My car is 2018 accord 2.0t The car just started jerking then I brought it to honda they said head gasket replacement needed, my car was properly maintained and it still happened

- the car's automated systems randomly applies severe breaking at improper times - the cars head gasket has blown and in turn has blown the radiator and thermostat

I own a 2018 Honda Accord equipped with the 1.5L turbo engine. The vehicle is experiencing a head gasket failure consistent with numerous complaints reported by other Honda owners online and through NHTSA. My vehicle began showing symptoms including rough cold starts, engine misfires, loss of coolant without visible leaks, and reduced engine performance. Diagnostic testing indicated head gasket failure and coolant intrusion into the cylinders. The repair cost quoted to me is extremely expensive. This appears to be a widespread defect affecting 2018 Honda Accord 1.5T vehicles. Many owners are reporting similar failures at relatively low mileage, often involving cylinder misfires, overheating, coolant loss, and major engine damage. This issue creates a potential safety hazard because the vehicle can suddenly lose power, enter limp mode, or stall while driving. Honda should investigate this issue and provide assistance or recall coverage for affected vehicles. Consumers should not be responsible for major engine repairs caused by an apparent design or manufacturing defect. Vehicle: 2018 Honda Accord 1.5T
