I think these cars are too new for anyone but a trained tech to know such a deep problem (who we have here luckily). The car should still be on warranty, no?

Sorry for the late reply...No not under warranty. Still driving it and the shocks still holding the pressure. I ordered the repair manual and hope it will lead me to a clue. My main concern is to find where is the Suspension module located. Bcse I get some diagrams and component locater views and it is not the same..thanks any way..
