I have a 2016 ST Package 3 with HID Headlights. when I use my high beams the left headlight gets stuck on high. The right headlight goes back to low and the high beam indicator shuts off. After a while the left will eventually goes back to low beam. This could be anywhere from 1 hour to 4 days. I have been to the Dealer 2 times. They can not duplicate the issue. due to my work schedule I can not always get there when this problem exist. The Service manager says it is probable something that is in the computer. he doesn't have a clue. I know it is the high beam activator in the HID light. the computer does not operate the lights and indicator separately. Any on seen this before?
