I just bought my 2018 Chevy Traverse and when I tried to turn the knob for the Traction Select the silver ring popped off so i put a tiny little bit of super glue on it and put it back on. Now what I need to figure out is if the whole knob turns or just that silver ring because if its just that silver ring then I need to pop it back off or go to the dealership and have them fix it or if the whole knob is supposed to turn then something isn't right. If anyone knows of any problems with this knob please let me know. If you've experienced any problems with your Traction Select knob and you know what was wrong it would be greatly appreciated but I looked all over the internet about this and can't find anything. Thank you and please let me know.
