‘04 350z anyone else had this issue

Car randomly throws “Slip” and lost of power but now suddenly “Slip,ABS, and TCS” all turned on and lost of power.. I swapped out the abs sensor a while back and recently I changed out all the steering& suspension parts in the front (left&right) as it was needed to be done but I just want to know what could fix this “SLIP” issue and to why the rest of the lights turned on
