I remember the disasterous recall they had last year of the V8 Tundras which had camshaft problems. I've also been reading about this new problem with the V6 Camry transmission. Apparently, the 2nd and 6th gear have trouble and can jolt or even stop functioning due to poor fastening. Since the summer of 2007, they've addressed this issue on their assembly line, improving the transmission's fasteners. According to Toyota, its affected 90 out of 5800 V6 Camrys. Since most Camrys are sold with the I4 engine, its not as big an issue. Luckily, this problem didn't infect the ES350 (which only comes in the V6) since that car's production began later and Toyota was able to catch it early.
I would agree that a lot of these problems seem to stem from Toyota's ambition to become the largest automanufacturer, but I wouldn't say they haven't had problems in the past. Many cars have problems right after a redesign. I think that now Toyota is producing so many cars, the problem is being projected that much greater. The V6 Camrys make a rather small fraction of the total Camry sales and only about 1.5% of those V6 Camrys are affected, but when they sell them by the thousands everyday, it gets reported that much greater.
My advise to anyone buying a new car is the same with buying a new Windows OS or a gaming platform when it just comes out; wait about a year after it comes out until all the bugs and errors are fixed.
