“I was on the highway with moderate traffic. My car would no longer accelerate due to a blown head gasket out of nowhere, I was on the far left lane and had to traverse over 5 lanes in moderate traffic while other drivers on the highway were going 60+ mph. This is a common issue among Honda Accords with the 1.5 engines.”

“Engine knocks and hesitates when accelerating especially uphill. Ocean Honda in north hollywood, california has checked, did drive tests and kept my car for 2 weeks and assured me the knocking and hesitation were gone. They even insisted they did not encounter any knocking nor hesitation when accelerating and driving uphill. It always does both and never went away.”

“2018 Accord touring 2.0 about 1800 miles on it. The car shifts very rough in the first 3-4 gears when the car is cold. Also happens at times when its warmer. One dealer claimed to have fixed it with a Honda approved break-in procedure. It did not solve the issue. It has happened each day I drive the car since I first got it about a month ago.”

“All of the lights in the dash came on . We took it to Honda , at first they said it was the coils and spark plugs. I had them replaced , the same thing happened again the computer read that it was misfiring on one of the cylinders . They kept it and ran several tests . They then tried to say that it the result of a bad oil change but we knew better. After about a month they said that it had over heated and blown the head gasket . I ended up having to use my warranty and pay a deductible.”

“My vehicle was purchased in 2021. It is a 2018 Honda Accord Touring model. The engine is a 1.5TRG. My current mileage is 88,405. About three weeks ago, my mom drove my car to the store and the dash lit up. By this I mean that the dash lights lit up for check engine light, lane mitigation, oil, etc. She was less than 5 minutes from the house and immediately drove back and parked the car. Mind you, I've driven a car with a blown head gasket. It smoked, temperature gage would show that the vehicle was hot, etc. …”
