On my 2004 Cadillac Cts the area where the backup lights are leaks from rain, or a car wash. This causes the constant replacement of bulbs because of rain and moisture getting into the area causing the short circuit of the bulbs, and corrosion of electrical sockets, let alone the risk involved of backing up and someone hitting our car from the rear because of failure of the back up lights, (we've had to replace the bulbs four times in 2 months). We took our car today to the Cadillac dealership, only to be told that they do not fix this problem, that Cadillac found the error, and that the entire section of the car has to be replaced. Yet we have to pay between 500. 00 to 700. 00 for parts and labor to have the correction made. For this to be a 3 year old vehicle, and for this to be a problem, that Cadillac knows about, this sounds more like a recall item that should be covered by Cadillac and gm.
