I have a 2011 chevy silverado 1500 I got 3 months ago. Has 32,000 miles on it. 3 or 4 time while driving everything freaked out in it, like locks go up and down, lights flickering, radio freaking out, it down shifting and not being able to steer it. The a few seconds ( 10 or so) later its fine. Then after you turn it off, it wont start back up, no lights come on no noises while trying to start it, nothing. If i take the battery cables off the battery and put them right back on, it starts fine. Took it in all times they say nothings wrong. Just got it back from the dealer 2 days ago and 5 to 6 times while driving ill notice the lights go dim then normal. When I shut it off after that he wont start. Anyone else have these problems?
