Thank you for your replies.
All the alignment tests I did were on newly paved roads with negligible slope, but your points are well taken.
I will certainly double check the tire pressure and see about those adjustments.
I will also copy the information on alignment you supplied and see what the service department can do. I have just under 500 miles on the car and want to put on another 500 to get an even better sense of how this car performs. Since I too do a lot of highway driving and it's important to feel secure on the road and not feel like I am in a tug of war with the car. I'm not as knowledgeable about what the adjustments mean but will do some research to understand more.
Thank you again and if you have any further tips or suggestions please feel free to pass them along.
