I've owned three Suburbans over the years; they were about the only thing out there that would hold my entire family when the kids were younger and all at home. The first one, I bought used and was a good truck until about 110,000 miles, when electrical problems started and the a/c compressor went. The next two I bought brand new from a large reputable dealer. Both had numerous problems (electrical, exhaust system, valve lifters, ball joints), most of which were cheerfully fixed under warranty but left me feeling that the trucks were undependable when the warranty expired at 36,000 miles. I finally gave up and traded the last one on a Toyota, since I'd had excellent luck with one of their little pickups bought used. 150,000 miles on the Land Cruiser so far, and not a thing done to it beyond regular maintenance and two batteries. It still runs like new. BTW It's full-time 4WD too.
Not trying to start a brand war, but that was my experience with GM and Toyota.
