Just took delivery last week and right away noticed a shudder from drivetrain every 3-4 seconds when driving at highway speeds. Happens over 100 kmh, most noticeable from 115-120 kmh. Dealer replaced front rotors but no difference. Any suggestions would be welcome.

Your car is in warranty. Keep returning to the dealer until a resolution is agreed upon.

Maybe you need to take a technician for a quick ride so you can point out your concerns, sometimes that's the only way everyone can be on the same page.

Took it back to dealer and left it there as it was early and too much traffic to hit proper speeds. Tech advises he drove it up to 130 km/h and could not feel anything. They called me later to go out with Tech which I did but we could not set cruise speed to check properly. As a precaution, he updated CVT software and advised to monitor and return if problem still exists. I have since had the chance to drive it again at set cruise speeds of 107, 113, 115, 120 km/h and problem still exists. Therefore, I will be returning to the dealer. Seems some rotating part is loose or defective as the shudder comes and goes every 3-4 seconds. My Wife has an identical car and hers runs fine so I know I am not going crazy.
