So I took my 2012 RAV4 in today (9/14/15) at Toyota Simi Valley for the recall, check EV MIL (gateway ECU) and motor/trans noise.
The service adviser named Garson assisted me and seems to know the issues that plagued this car. After writing me up, I waited about 15 minutes to go on a test...
I live in Chatsworth and I have the same dilemma as you. I wanted to get my RAV4 repaired at the most experienced place possible.
At first I was leaning towards Carson Toyota for the same reason as you but I'm asking myself if it is worth the drive.
My experience with service is hit or miss...
