 I have owned this vehicle for 14 month.  It has been on a flatbed truck FOUR times!!!! Thermostat failure caused car to shut down while I was driving on the parkway - stuck for 3 hours.Brakes seized and calipers would not free the front wheels - stuck for 2 hours.Coolant reservior EXPLODED - coolant everywhere - stuck for 3 hours.Oil Tank EXPLODED - oil EVERYWHERE - stuck for 3 hours.The only saving grace is that my local dealership has excellent service and has provided me with a loaner vehicle every time mine was in the shop (it has gotten to the point that I feel it needs repairs whenever it is dirty so I at least get a free wash out of it....).  The X5 is pretty.  It handles very well.  It has great pick-up and braking capacity.......but it has ZERO reliability.  NEVER AGAIN!
