 I have not had any major problems with 
my Expy.  It was involved in a 
transmission, tire and seatbelt recall 
(but I never experienced any problem)
and put in the shop once for sudden 
race of the engine while idling.  They 
replaced a filter and the problem was 
solved. I have the 5.4 liter and it has 
great power and the gas mileage is 
actually pretty good for an SUV.
