The one REAL issue, and it's not performance impacting, just an annoying noise would be the transmission whine with the V6. Solved with a TSB but still a nuisance. Other than that, most (ALL) of the issues I have had with the Rav4 have been with the dealer service department. I've had the car for 10,000 miles/8 months and it's been great overall. Once I got through all my headaches with the transmission TSB and my awful dealer, it's been just oil changes and daily, reliable, no non-sense operation.
