Ouch.... Wish you good luck.... My 5th Gen 4 runner (same as yours, but 2010 and limited) has been a POS since I got it.... I will be trading it soon.
In short:
Poor gas mileage (17 in town)
poor engine performance (spend an extra 400$ and get an after market air box)
tranny is slow to react
electrical problem galore
turn radius is worse than some full size pickup
I think the worst for me is the lack of power....
