I was driving for about 45 minutes down the interstate in my 2014 Silverado. I went to pass a car and the cruise shut off when i turned the blinker on. The dash lights would also dim for a second when i pressed the brake or turned on the blinker. It continued to do this until i pulled into a parking lot and shut the truck off for about 30 minutes while i was in a store. I should also note that when i pulled in the parking spot it was like the power steering quit for half a second like it has done a few times before. On the 1 hour trip home it drove normally with no issues. I have had other electrical issues like diming headlights when pressing the brake and also headlights dimming in time with the blinker. Usually these problems happen when i have been driving for 45 minutes or more. My battery is about a year old so i dont think that is the issue. Has anyone else had these issues and found a fix? Thanks
