The entire time I've owned my 2007 SEL-Plus Edge I've noticed that for the first couple of minutes after a cold start that when I brake I feel and hear a 'grinding' noise coming from what I assume are the front wheels when I brake. After a minute or two the problem goes away.
I took it to the dealership to have them look at and of course they said that they could not reproduce it. I looked in the manual and see on page 214 the following passage about the 'Advancetrack' stability control system and it states,
"During AdvanceTrac with RSC operation you may experience the following: A rumble, grunting, or grinding noise after startup and when driving off"
I assume that this is what I'm experiencing, but when situations I encounter it aren't during times that the stability control light illuminates - I've actually had the light come on once or twice on a slippery road so I know the difference. I also feel that while the sounds are similar, but brakes felt different and the car decelerated when the traction control system engaged. So now I'm not so sure this is the same thing.
What should I do? I can pretty easily reproduce it myself every morning when I leave for work, but like I said, it only lasts for a minute or two and there are no other symptoms (braking responds fine, etc) it only happens when the Edge has been sitting off for at least a few hours.
Thanks for your time,
Jeff
