Where is the charcoal vapor canister located on a 2006.5 Kia Optima EX model. on 2007 Kia Optima

I was told it was behind the driver side rear wheel, it isn't. That is true with older Kia's. This car has dual exhaust which makes it impossible. I searched all over under the car and under the hood by the firewall. The car was diagnosed be a dealer and again, asked where it was located and told in the rear of this car. How could I have missed it. On my daughters older model Kia, it is the size of a small cooler. Thank you for any help
