GLS Hard ride

My X166 that I have had for 2 months (2016 model) seems to ride quite hard even in comfort mode. I feel every bump and crack on the road. Could it be suspension issue or is this normal? I also feel a very light but noticeable buzz/vibration through the wheel almost like I can feel the road beneath me!

any advice on what to look for?

@carrollf How long has the vehicle behaved this way? How many miles are on it and how many have you put on the vehicle? Does it make any other noises or have vibrations?

I have put less than 500 miles on it - has 60k miles now. Only other noise is an occasional noise when reversing out of the driveway or pulling away slowly from a standstill - hard to describe but comes from the rear and almost sounds like water moving from one side to another - not a sloshing noise but more a very muted knock. Sometimes just hear one of these knocks and sometime 2 or 3 but then goes away

What are the condition of the tires, and pressures you are running? When I got mine in July, it had worn out Contis on it. I replaced them with Michellins and the car drives/rides as it should.

it has 4 brand new Continental 275/50/20 on it. They were over inflated by the dealer initially but I have drought them down to the recommended level. Improved things a bit but expected softer ride
