Hello,
 
	New to this forum, so I apologize if I am posting in the wrong spot.  My 2019 Edge all of a sudden is loud upon start up and vibrating while moving slowly (forward and reverse).  When brake is completely pressed or in drive it doesn't vibrate.  When I take my foot off the gas or brake, it starts up again. 
 
	Mechanic could not figure it out.  Anyone seen this before?
 
	Thank you!
