I have owned many cars and never had a continuos rattle. It is not a slight rattle. I have commonly owned Toyotas and have never had rattles when driving. I do not think you have the same noise in your car. I am sure Kia are happy that you do not mind if your car rattles when you drive. The idea that defects in cars such as persistent loud rattle from the truncK is acceptle is the real joke! I hope you never get the issue on your new car.
