For the last few days, I have noticed the steering wheel on my Model 3 shaking. It has happened when getting off the freeway speed was 40mph, and when switching lanes on the freeway at 65mph.
It is intermittent, and feels almost like a wheel balance issue.
The car is less than an month old, with about 900 miles, and I have not hit any serious bumps or curbs.
Did notice the tire pressure is 41psi in two tires and 42 in two tires.

Any ideas as to what that mini shaking?
 
when switching lanes on the freeway at 65mph.

Are you signaling when you are switching lanes?

From the manual:

Lane Assist also warns you of undesired lane
departures by vibrating the steering wheel
slightly if a front wheel passes over a lane
marking and the associated turn signal is off.
This warning is active only when driving
between approximately 36 and 90 mph (59
and 150 km/h). To turn this warning on or off,
touch Controls > Autopilot > Settings > Lane
Departure Warning. Your chosen setting is
retained until you manually change it.
 
As others have suggested, it could be lane departure warning. If you're using your blinker and it's still happening, then it's a problem and you should take it in for service. If you're not using your blinker, then, well use ya blinkah!

I was feeling a slight vibration in the steering wheel. There was a 2psi tire pressure difference between the left and right side tires (left higher than right). The right side tires were inflated to match the left. The vibration went away.

I didn’t expect this to make a difference. I have a P3D+.
 
I have had similar issues with a slight discrepancy in tire pressure. I noticed that it was worse when the tires were cold, and would then go away. This is common on AWD cars, though I'm surprised to see it in the Tesla, since the front and rear wheels are not directly connected.
