My Accord made a loud thunk when I started the engine and it rocked forward and back just a slight bit.
This is a 2012 Accord 4 cyl. automatic trans. This has happened twice, first
time I looked and noticed that the front skirt was on the concretebump in
the parking lot, I thought maybe when I started it the car moved and the
skirt popped. The second time it was in the street, nothing under the car. I
turned the key and it made that loud thunk, the car moved about an inch
forward then rocked back. I do not notice anything wrong while driving.
What could it be?
