2005 cadillas Sts - frame rotting out - car is garage kept. Upon inspection on my lift this weekend, I found substantial rust to both lower frame rails just behind the mounts for engine cradle. Manufacturer fills the frame rails of this area with foam which absorbs and holds water and rots the frame rail from the inside out. This is definitely a manufacturer defect. Now looking at thousands to repair a vehicle in otherwise very good condition.
