For the past week, but car will go into a minimal limp mode it seems when doing agressive driving. Quick accelerations, hard turns, etc. Seems like it's related to the wheel slip differential or something.

Basically what it does is this:
Accelerate hard, hit about 40ish and then it shows on the dash "Continue driving possible: Chassis" and then it takes it out of traction and won't let you go back into traction mode (pressing the DSC button once). The fix is to turn the car off, open door and close, then start the car again and the error is gone.

Connected the car to a scanner and it doesn't find any codes because it's not a CEL error, it's a system error of some sort. I have an appointment for Tuesday morning so we'll see what they say. It's easily replicated every time, although a few times it would just come up when driving down the highway for 30 minutes.
