I typically turn off the traction control system when I get in the car, unless it's raining outside. Saturday night I did as normal and turned it off a few seconds after starting the car. As I was doing other things driving down a side road (not playing on my phone, basically just not paying much atttention) I felt a jerky feeling and as a reaction let off the gas, didn't see any dummy lights on anything, it was dark so I figured I ran something over. As I then turned onto a highway and accelerated off, at about 50mph the traction light started flashing and the traction system began pulsating the brakes causing the car to jerk all over the road. Again, instinctively I let off and when I saw the trac light flashing I reached over and turned it back on and as soon as it was on, everything went back to normal. There were no further lights and no further unwanted braking pulsations. I haven't driven it with traction off since as I don't want to have that crap go on again doing highway speeds. Anyone else ever had this happen? There was no tirespin, no wet pavement, no conditions that would create a traction related issue. And again, this was with traction off.
