After 3 months of new car ownership and appx 2000 miles when you hit 52 mph there's a loud roaring noise that abruptly stops. Its louder in cold weather. Same noise also happens at lower speed of appx 35 -49 mph but is muted. Car has been into dealer 5 times for same issue ad Honda hasn't been able to fix. Noise happen on any road while in motion. 1st dealer check was in Nov 2018. I filled complaint number: 11303013 but have never heard back from anyone. Multiple Honda hybrid owners have this problem.
I bought a new Accord in September 2018, there was noise in the car, the engine also had abnormal sounds, terrible dealers, terrible service, terrible american Honda! they can't solve the problem, just shirk each other's responsibility! recently I found that the lane keep system is not working properly. I have already gone to the Honda service station 10 times for these questions! but they just told me that these are not problems. It¿'s just unacceptable.
