I got a brand new seat,which I am finally completely happy with,as it does not have any wrinkles.

Honda kept my car for 3 days to investigate the annoying rattle.

I got my car back,and the next day ,heaerd the rattle again.
It had disappeared for 3 weeks.

I dont know what to do,as know that the dealer has no clue where it is coming from,or how to fix it...................................
