i leave it OFF in the rain- believe me its dangerous in the rain, i was making a left turn at an intersection, and the tires spinned, it started shutting cylinders down, so i got off the throttle, got back on it, and is started bogging down, i got off and got on it again, - again it bogged down, this happend a few times, like a game. I nearly got in an accident.
Also, one time i took a corner too hard, and i went a little sideways- no biggie, but then the traction control kind of kicked me the other way to straighten me out, so naturally i counter steered, and it nearly kicked me into a wall. I turn that POS off- someone outta sue ford for putting that death device on in the first place.traction control in a mustang is not like traction control in a Lexus
