i have a used 2019 edge, 46,000 miles. the traction control is very strong and if you dont have both hands on the wheel its breaking action, when changing lanes, can pull you into oncoming traffic, the off/on button does not seem to work as it continues when the indicator says it is off. there was a brief period of about 4 weeks when it did not work at all. very comfortable driving during that period. i did not do anything to create that situation. then for some reason it starts working again. not sure what to make of it. i did have head gasket replaced 2 months ago, not sure if that had any connection but do not remember having an issue before that, could have and just dont remember as i only had car for 3 weeks at that point. any thoughts. saw where traction control module, if it is a plug in unit can be replaced fairly easily
