I have read about some people having trouble with their transmissions. I have only seen a couple TSBs (technical service bulletins) for transmission fixes and no recalls.
The best thing to do is to ask the dealer if the vehicle you're buying has had the latest updates and go from there. It doesn't seem to be affecting all the Camrys.
Toyota makes a good product, I've been driving one for 19 years now. I can't say that I have any complaints!
