Like I said at 70-80 mph my car would shake on the highway. At first, I thought about the possibility of the road. However, my previous car same make and model just different years didn't shake on the highway back to home. Also I bought my car from the dealership and it's been a year only.

my car would:
-Move left to right.
-Steering wheel doesn't move left, right or shake.
-It doesn't drift to another lane (meaning it stays in its lane but constantly move left and right like shaking).

what I've done so far:
-I checked the tire pressure making sure all four wheels have the 32 psi. (with a digital air pump and the tire shop mechanic adjust it)
-Did a tire balance on all four wheels.

Did you check for a bent rim or shifted belt in one of the tires? Also, are the tires worn evenly?

Let me know.

I would jack the front of the car up and grab each wheel and move them back and forth to look for looseness. These guides will help us:

I will upload a video tommrrow when i get a chance. Also I will jack up the front tommrrow too and let you know about it.

(1)Did you check for a bent rim or shifted belt in one of the tires? Also, are the tires worn evenly?
-No my rims are not bent. I'm not too sure about the belt in the tires. The tires looks new and also when i took my car in even the mechanic question why i need a tire balance when my tires are new. So i doubt its worn out.
