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.

    Intermittent failure of drivers side front turn signal with fast signal indicator. Signal lamp is out when it happens, but rears are fine. No repeating indicators or causation, simply stops working at random intervals.

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

    we to have had to replace the lights within in 2 months of each side failing. the passenger side is VERY difficult to replace as you have to remove the front bumper and side panel. the local Cadillac dealership quoted me $550 to replace the bulb! my step dads brother who is a mechanic was ablt to replace it in a couple hours!

    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.
