thanks for the responses guys. planning on taking her in this week. issue is getting worse - see video below
it's icy/snowy outside and my car is now doing this when i break, and sometimes when i accelerate also. you obviously cant tell in the video but the break pedal and entire care vibrate pretty aggressively. same thing happens when i accelerate sometimes.
my transmission also jolts a ton.. sometimes just when going into reverse, sometimes when going from 2WD to 4WD. again, brand new car, 600 miles..
