Very little...
Squeaky belt after it rains. Dealers perplexed. Replaced pulley, S-belt and even catalytic iconv (?!).
Noise from right front wheel. Possibly a bearing. Tires cupping some.
Superbly reliable and nifty in the city of SF even with two small children.
Cargo space is excellent. Rear passenger room isn't.
Slow mid-range accleration... but manageable on freeways if you plan ahead and can tolerate a buzzy engine. Really in its element in and around town or off road and for needed cargo space.
UPDATE: 38,000 miles. S-belt just replaced again for squeak issue. Other than that, no problems at all. 4th car. Wife prefers over Pathfinder and T&C.
UPDATE: 57,00 miles. Still no problems. Went to full synthetic @ 40,000. Belt squeak went away. 40K service as well. Bullet proof thus far... but well-maintained. Virtually, no resale value... so we keep her in the family.
