The way I understand it the heat shield isn't attached real well on purpose so that in the event that it would catch of scrape it would tear away without causing major damage. Nonetheless I had some issues with my 2012 Versa Sedan with rattling and the shield was the problem. It happened again and I just had them remove the shield totally and leave it off. It's not really necessary as long as you aren't parking on piles of dry leaves. The dealer had no problem leaving it off for me. It won't be an issue going forward.
