Lets be realistic - NO manufacturer is going to replace your car for rattles & I doubt any court of law anywhere in the world will rule in favour of replacement for rattles. Best option is to try and work with your dealer to get the issue resolved, in case, Prerna is not able to solve this problem, approach another dealer for the same. It's better not to focus too much on PDI. Dealer's across manufacturer's merely stamp the booklet which stands as proof that PDI was done. In reality, they probably do nothing. I hope your issues are resolved to your satisfaction and do update the forum with the same.
