I have smiliar problem with my 2010 Camry LE. I did not know Toyota only covers first 12k on alignment. The car had alignment problem. I had Sears did alignment at 17k and 23k. The problem did still existed. At 32k, I had to replace all 4 tires and went to a Toyota dealer to have an alignment done (I had to pay). The car only drive straight for 500 miles. I went dealer again and another adjustment was done. It is driving straight now.
You need to have a Toyota dealer check your alignment and have them print out the alignment specs. Most dealers can check alignment for $15 to $20. If your car needs an alignment adjust, they will charge $70 or more for the service. If there is any alignment component needs to be replaced, dealer should replace under warranty.
