2005 Cadillac DeVille DHS 4dr Sedan (4.6L 8cyl 4A)
After purchasing our third Cad I am just as disappointed in the area of engine reliability that it makes me sick. The engine is now burning oil to the tune of a quart every 100 miles or so. I have found other owners who have the same complaint and it looks like I will have to take it in for an overhaul. It only has 45,000 miles on it and yet it uses this much oil. There is no leakage nor smoking that I can see. I don't think we will ever buy another Cadillac.
