Hello!

I have a 2006 Azera Limited and its having this weird issue. When I apply the breaks hard, or while turning.

The dash lights dim and the ABS lights come on. It was taken to the mechanic and he tightened down a lose ground strap, and that seemingly made the issue go away for a week or so.

Has anyone else had this issue? Or know what may be the cause? I don't want to have to look for a new car at the moment and any help would be very appreciated!
