I have a 2015 Silverado and sometimes I can not get in to the truck. I use the key to unlock the driver door. Something is locking the truck when I unlock it, last night I left the truck open and this morning it was locked with the mirrors folded in. This happens while driving so it is now a safety issue. I reach down for the folding button and they open, then they close again. Any advice, thank you, Ed
