Could there be a problem with my new car since the ride is not as smooth as before?

[cloudthoughts]

I have an RX350 and it use to be very smooth.. the only thing is that recently I felt that its not as smooth anymore, for instance right now I can feel the shocks and the car rocks more when I run on bumps now while before it was barely noticeable... New driver so I am clueless what I should do or have checked? maybe need oil change or is it the tires?
oh yeah... 2 months and ran 1500 miles already

Nothing should be wrong at 1500 miles - take it back to the dealer for them ot fix it under warranty.

Tires are due to be rotated every 6-8K.

You could do a break in oil change now (I would), but oil changes are actually due every 3-7.5K depending on if you do city, highway or both. Think of 3 as 100% city and 7.5 as 100% rural highway never stuck in traffic and think of it as a line graph - find where you fall and use that.

First, check your tire pressure. If one of the tires lost pressure it could cause the rougher ride. Only one or two pounds of pressure can make a difference. If the pressure is good take a look under the car. Do you see anything leaking near the tires or wheels?
