I have an 07 Ram 1500 Hemi. Laramie Edition. If I'm at a stand still on a hill, transmission in park and I let off the brake, a clattering type noise vibrates through the brake pedal. I don't know where the noise is coming from, that's just where I feel it. It has the ESP stability control system. Would that have anything to do with it. I hate to call the dealer and say I have a problem if this is normal. It reminds me of when the ABS systems is engaging. It's that type of noise. I know I'm not giving your guys much to go on, so if there is any questions you have, that might help me, let me know. Thanks.
