Our turn signal worked incorrectly, as it sometimes did not work and sometimes it would signal the incorrect direction. This was "fixed" by the dealer replacing the turn signal arm and updating the software. However, within months it started having new problems. Rarely, it would not work. However, more common was that when the turn signal was on, the headlights would shut off. Once the turn signal was off, the headlights would come back on. This has continued to happen more and more often. We have not brought it in for the problem yet, as it seems like a continuous string of issues with this car and just have not gotten to it yet.
