2009 BMW 3 Series Sedan 328i xDrive 4dr Sedan AWD (3.0L 6cyl 6M)
Rattling Noise, high pitch noise and etc.
 I bought my 328 i AWD sedan in May 2009. It has 1500 miles. I am extremely dissatisfied with it with the following reasons - Under the hood BMW uses many plastic protection covers that cause rattling noise on rough roads - Rattling noise inside both rear doors - Rattling noise coming from cheaply designed cup holders in the front and rear. - Rattling noise inside the armrest between two rear seats. - Major rattling noise coming from inside the dashboard. - Poor engine noise insulation. The hood surface facing the engine does not have any foaming, unlike many other cars. - Flat drive tires cause stiff road experience. - Poor speech detection. This is my second 3 series, but it will be the last.
