My 2016 Silverado 1500 lately is flicking (best way to describe it) on and off while driving. I’ll be driving and the engine power will cut off/on, the power steering will cut off/on, the locks will change unlock/lock. All this happens at the same time and it’s so quick that the radio isn’t effected and sometimes it just feels like the wheel is jerking from hitting a curve. So sometimes it all happens in half a second and other times it might be a full second. No warning or caution lights pop up during or after. It was doing it really bad and then I pulled into an O’Reilly to test the battery and they found it to be normal but then that like, reset the problem or something because it went from doing it all the time to not doing it for several days. Now it’s back to doing about 2-3 times when I take it out.
