I have a 2012 that is having tail light issues. If I turn the turn signal to go left and engage the brakes at the same time. The turn signal dims and both back up lights blink. Then the left tail light will randomly go out. If it's parked with the head lights on and I turn the turn signal on both tail lights and reverse lights blink uncontrollably. I have changed bulbs, bulb sockets and went to aftermarket LED tail lights and cleaned the turn signal switch connections. I replaced the brake switch, checked all visible grounds. I took it to a dealer and they said that they would be doing same thing I am doing to figure out the problem. If anyone has had this issue or similar I sure would appreciate your input.
