I bought my 2004 in 2005 and it went in the shop a few times for this or that but was always taken care of. always given a Cadillac replacement vehicle but my only complaint are that the turn light go out a lot because they are running lights also. I love my car my wife has a convertible mustang and we always take my car because of comfort it rides like a dream the a/c is so good it will make you cold on a day of temps over 100 degrees. Id buy another in a minute!
the a/c and heated seats
the running light should be the turn signals and, if they are, make the bulb easy to change. which it is not!
I had the same problem with my running lamp/turn signal failing on the drivers side. As it turned out, the wire on the plastic base of the bulb was getting so hot it would melt into the base and lose contact with the socket. GM came out with a replacement socket that is supposed to take care of the heat problems. I installed one and haven't had anymore problems.
