I have a 2014 and the bumpy ride has always kind of bothered me. Any bad road and the car just feels like it has no cushioning. My friend keeps bugging me about it and says there's something wrong with it, a Cadillac should not drive this rough. I've taken it to the dealer a couple times, they changed the front struts awhile ago but it's not much different. I keep getting told it's the low profile tires and low to the ground, is that the case? I have it on touring mode all the time and even lowered the tire pressure.
