I've had two so far. A 08 Sportage with the V-6 engine then traded that in for a 11 Sorento with the bigger V-6. I had about 60,000 on the Sportage when it was traded . Never had any problems other than regular maintenance stuff. The Sorento has about 14,000 on it now.
Only reason for trading was to get a stronger engine for towing the trike, plus getting more room in the bigger SUV. It gets me 27-32 mpg except for towing then really takes a hit there. Last spring I replaced a 14 year old Dodge pickup with a Nissan Frontier so that gets all of the towing dutys now.
