The front turn signal and and daytime running light bulbs are prone to premature failure. Our technicians tell us that these bulbs can be very difficult to replace.

    Dealer initially replaced the bulb. It either went bad or something else was wrong because it stopped working within a week. Have taken it back in and they are thinking the socket is bad, not sure of the outcome yet but it's interesting to know others have had this issue.

    Headlight went out and I realized it requires bumper cover removal, awesome. No easy solution yet...

    Passenger running light works sometimes but mostly not. When I use the turn signal to go Right it blinks rapidly. I can see it working in the rear but it's not actually blinking in the front. Is an intermittent problem right now. Thinking turn signal switch is going out.
