Since I bought the car, the wheels made terrible noise in corners or at T-sections. Passengers are scared the hell out of them and hold themselves at the dashboard.

I have 21 inch wheels but the tires are not following the road but scrape over the tarmac or stones. After 17.000km the first set of tires is gone. Had an old model Maserati QP before this one and tires easily lasted 50.000km. Maserati call it car properties. Wasn't mentioned when the car was sold. Haven't heard anyone else about it.
