I bought the 2005 Yukon XL in the summer of 2012 to replace my 2003 Yukon XL that was totaled in an accident. Since purchase I have replaced: Front diff, Transfer Case, Power steering pump, Alternator, Steering gear box, Hydro Brake Booster (all under warranty). I have also repaired the inoperable 6 disc changer, replaced my steering wheel control light bulbs, and installed new front shocks.
