I had the same malfunction and the dealer fixed it this past Tuesday. It was the left side and both angel eyes were out however they told me only one needed to be replaced. They possible could be stringed together like christmas tree lights when one goes out they all go out. They did not charge me but let me know CPO does not cover it, to my surprise.
