after pulling out of my drive way in reverse then putting it im drive and start going i hear a knock it sounds like the brake pads are loose. idk what it could be any one with the same problem??

 

I have having the same problem. About to take my car in Friday. A mechanic looked at mine and he thinks it the motor engine mounts because of all the play from the engine when moving gears. You have to open your hood and have some step on the gas and brake same time to see the movement.
