2015 Sierra throwing C0400 code

[HiggySTL]

Driving to work yesterday I got a message in the cluster gauge screen saying "Stabilitrak Needs Service" and then my ABS and Stabilitrak lights stayed illuminated in the dash. Took it to the dealership and they said that it was my right front hub assembly. It had a lot of play in it and caused it to throw that C0400 code. They replaced the hib assembly and sent me on my way. Just thought I would mention that to see if others have had this. I tried to do a search and didn't find anything, so I figured I would also mention it for other in the future to search and find info on.

 

Thanks for listening!
