I have 2015 SXT Plus and for the last yr the passenger signal indicator pops up with or without my turn signal on and says it's not working but in fact it is. The indicator will blink at normal speed then rapidly. I can see through a reflection of a vehicle in front of me that its working fine. I've parked and tried my headlights, parking and so on everything is working. The rear lights work fine too. I'm at a loss and very annoyed with this.
