Soft limp mode after triggering traction control?
Have a 2019. On occasion, I'll get a soft limp mode if I trigger traction control. Only way to reset it is to turn the car off and back on again. Anyone else had any experience with this?

With traction control shut off, in sport mode, or default fully on? If it is the latter two scenarios, please test with it T/C shut off (hold the button down for approximately 5 seconds) to see if the problem persists.

Sounds like you are hitting overboost protection on the JB4. i would send a log to BMS and see what they say. the log will give a number at the top if the car was in a soft limp mode by the JB4 (Overboost = 1, AFR lean = 2 ect)
