Very little in 21,000 miles.
BUT...The car has an intermittent miss that the dealer cannot find, the front drivers strut pops indicating the strut bearing is bad, but it isn't a serious problem yet.
Overall and considering this vehicle is an ex-police detectives car I am very pleased. The county I purchased it from maintained the vehicles with synthetic oil and kept them very clean.
I know exactly what you mean. I test drove one today, but my dad would not buy it for me because it had a miss. But overall it's a great car. Really big, though.
