| Description of the problem | In my opinion there is a defect in 2009 hyundai genesis sedan v6 model the suspension behavior changes abruptly when going from driving nicely smooth freeways to more stand surfaced urban streets. The ride on the former is normally smooth, firm but acceptable however on the later the wheels bounce so badly that at times they break contact with the street surface. It literally tosses the rear occupants around and makes it difficult for the driver to control the vehicle. I have tried everything i can do including change the wheels back from the optional 18inch rims to 17inch rims and increasing the tire series from the sporty 55 series to the must compliant series 60 tire recommended by the factory. |
