My Electronic Stability Control System........
Is taking over!
I was driving on the freeway today and the ESP light briefly illuminated and cut power from the engine. I continued to drive and this happened a few times before I turned the ESP off and was rid of this issue.
Anyone ever had this problem? My low brake pad light just illuminated on the same trip.

Only the inner front pads have wear sensors.
That outer pad is fine, but it's not inconceivable that an inner pad is worn to the limit.
BTW: With no wear sensors at all, you also need to keep an eye on the rear pads.

Don't you just listen for metal on metal sounds then rush to change your pads as quick as you can like everyone else?

If I forget to turn it off, that's happens to me on track.
When cornering at the limit, ESP usually brakes an inside rear tire to insure safe but boring understeer. [It brakes an outside front tire if it detects an imminent spin.] On track, going thru 15 corners at the limit every 2 minutes, ESP would quickly overheat the brakes if kept active. To save you and the brakes, ESP eventually cuts the throttle.
If I'm not mistaken, ESP uses only lateral g sensors, speed, and steering wheel angle to determine if the car's going the way it's pointed. Perhaps one of these is sending an incorrect signal to the ESP computer. And if ESP was being activated excessively, you might want to check your rear brake pads for wear.

Re: "Don't you just listen for metal on metal sounds to change your pads?"
Not sure if you're joking or not. On my S8, I can easily just look thru the wheel spokes to see how much outer pad is left. I check the inner pads at 3000 mile intervals when I rotate tires.

depending on the brand of brake pad the sensor is sometimes in ...
the center of the pads wear area, so although it may seem like half the pads life is left, the sensor is getting tripped.
