Mine was built late Feb. 2009. I had no consumption issues until exactly after the warranty was up (160,000km). I never pushed it too far between changes or anything either - about 3 months or 8,000km (5,000 miles). Now it will consume approximately a quart in 3000 miles - depending on driving conditions. Since my wife drives it now - it gets changes twice a year, or about 3,000 miles apart - so I never really need to add.
My brother had an early build 2009 (March 2008), which was consuming a fair bit by that time. He wasn't always that diligent on following change intervals though - and with his being a manual, it revved higher all the time vs my auto. With the 2.4 FWD, the auto actually revs slightly lower in 4th than the manual in 5th. Strange gearing selection on Toyota's part in my opinion for the manual. Made it a bit "buzzy" to me on the highway, where I don't even notice the engine sound at all in mine at the same speeds (65MPH or so).
If I had known about this issue prior to buying it, I may have been tempted to get a 1.8 - but for the bit of towing I needed to do, the extra power and larger brakes made it the wiser choice at the time. I liked the more relaxed feel of the 2.4 on the highway too. Hopefully we still have it around for several more years.
