Back of the cars rattles because of bass?

Its 2017 honda civic touring only bought it an year ago. I went to them before and they couldn t fix it. Can i threaten to sue them for this?

Added (1). some said turn down the volume: it still does it even with very low volume

Turn down the volume.

No, you can't sue over something frivolous like that.

You need to empty the fish from the back of your car.

"can i threaten to sue them for this?"

Sure, you can threaten to sue over anything…

Sure have fun
