This is my observation from driver’s seat : Whenever I go over the bumps the front is so smooth, but the back I think it bumps longer and makes whole car body in the back makes a falling sound and because of that there are very slight creak noise coming from the back .I applied today gummy pfledge everywhere just to maintain the weather strips, I still hear the slight squeaks but as I said earlier they are very slight.

The front is smooth during the bumps, but the back noise feels like the car is like a bus. Is this normal? When I sat in the back the ride in the back is smooth enough too, it's just the noise when you are in the driver's seat that you hear from the back.

It's a 2018 model and got 68k miles on it. I just got it last week from the Lexus dealer, it is certified, and it has four more years bumper to bumper warranty with Lexus. In case if the struts are not good, would the dealer replace it or are they gonna say it's a wear and tear issue?
