I have a 2013 accord, drove about 480miles and now I notice that it's vibrating when its on idle mode (at the red light for example).
is this something normal?

 

welcome to the forum. If you did not have it vibrate when you received it, document what is happening and when, then take it to honda for warranty. they should make it smooth again, like it suppose to.

 

No way would I live with something abnormal in a brand new car,time for a dealership visit.

 

I took it to the dealer this morning and they said everything is fine. car is still new. I dont know if this is serious or its just in my head.

 

Does the vibration go away when in park?

 

Yes it goes away when on park mode or neutral

It vibrate at 750 rpm

 

Then its transmission related.

 

take it to the dealership and continue to complain, go on a test drive with the mechanic and allow him to feel the vibration, also make sure this is documented in their paper work. If they continue to refuse to work or fix the car, take it to another dealer and have them check out the vibration. If all else fails, call American Honda and advise them of what is happening and how many times you have taken the car in for checks, and their response. Don't guess what the dealer said, make sure you write down what is said and done.

 

I will do that. thanks acmech52

 

Hope you get the problem solved,its rough starting out with a problem on a new car.
