2015 gmc sierra electrical issue

[siego99344]

Good afternoon,

 

I have a 2015 gmc sierra 5.3 4x4. I looked tirelessly through the web with no answer through my issue. When am parked or going slow i get feedback from my speakers with them being off i have to press the brakes or turn the steering and the feedback will go away it returns after i either release the brake pedal or leave steering alone. I will be driving and my dash will turn off and stabiltrak will indicate and then go back to normal for a few minute's. also my park assist will disable. Last time i was going 10 mph turning left and the truck turned off. put it in park turned right back on...  CAN SOMEONE HELP ME PLEASE   thank you

Thanks for the quick response but i already added a new ground to the frame like i read and its still doing the same thing. I will look at that and see what i find thats new.
