The license plate back up light assembly to my Cadillac Cts 2003 mysteriously came up missing. This is a costly piece to replace. I have called multiple salvage yards to find out that a lot of them receives 2-3 calls per week for this part. I talked to a claim representative at state farm and he so happened to have had 3 open claims within one month. All conversations lead this to being a defect in the making of the vehicle. Not having this part, leaves my brake lights exposed.
