@wtm0325: Thank you for consolidating the common problems from this car...

my rattling sounds came from the side of the front passenger seat's door pillar it's freaking annoying... I knw it's a hopeless battle if it is being rectified at our SC, but I will try...

by the way, our car is just less than a month...

Yes, it's a common problem I will try to find some accessory shops that can help us... it's kinda hard to find some decent shop if your a stranger

Thank you for the input Eithanius, I do hope that your problem with this car will be ok... I did read almost all of your posts...
