Yes, it is the same platform, but it's obviously not eve close to being a "re-badged Avensis".
Re-Badging is taking the exact same car and applying a different name to it, like the Atenza to the Mazda6.
Platform sharing is taking the same frame and applying different bodies, drivetrains, trims, etc.
While you can compare reliability levels amongst rebadged cars, as they are the same cars, you cannot compare reliability ratings with (most) platform-sharing cars as they can be totally different aside from the basic frame. It'd be like comparing the Contour to the Escape.
