constantly correcting the steering, all speeds

I noticed when driving my New Nissan Roque that I could never get comfortable steering it, I am always making micro adjustments to keep it on the road, Not that it pulls to one side and if you let go of the steering it will stay straight, The Nissan technician took it for a road test with me and did recognize the issue but told me nothing could be done about it. I have older vehicles and none of them drive like this. My wife has the same complaints when driving. Is there anyone out there experiencing the same issue and was there a solution. Rogue man
