Hi guys, would just like to seek some input from the members. Got my 2012 f10 528 msports in july, found out that the passenger seat rattles over uneven roads, it is very obvious and the rattling sound can be reproduced when the car is stationary by tapping on the seat rest, like it is loosely fitted (and no its not the sound of the seat belt hitting against the pillars). I've so far sent the car in for like 6 times to no avail. I have been kind and patient in getting this fixed but now that i have lost my patience i demanded and official response. Today the dealer emailed me saying the seat rattling is confirmed and expected for 528 msport because and i quote "vibration is typically transferred via(NVH)Noise Vibration Harshness from the road and wheel. Its more prominent with the low profile tyres and with active damping control suspension", to which i shoot back then explain the rattling when the car is STATIONARY. They have acknowledge the issue and fail to make known of this anomaly to its buyers prior to purchase. So for anyone that are considering the msport, please clarify with your dealers on this. Just wondering if they are acting upon instructions from bmw as i wanted to claim warranty for the entire seat. On top of that my driver side window also rattles which they have not fixed until today and asked me to come in again for the umpteenth time. Wasting more of my time and leave, especially when i am already busy with a newborn, uuurghSo far regretting every moment of my first bmw, my old merc gave me no problems whatsoever. Sigh
