 This is without a doubt the worst vehicle that I have ever owned.  I am 55 and trade every 2 years.  I traded out of a Lexus LX470 into the Infiniti QX56.  In the first 20,000 miles the brakes failed 4 times.  The rotors replaced & resurfaced 3 times.  The ABS and skid control malfunction almost killing me.  It is a noisy, rough piece of junk.  Traded it today for an 07 Escalade.  WHAT A RELIEF!  The Cadillac is far superior in ride, quality, and technology.  Not to mention fuel economy.  The weird noises, parts falling off and brake failures on the QX are almost laughable.  A true GARBAGE TRUCK!
