From Hawaii: I have a 2017 SE Hybrid. While detailing the car, I noticed that while the left read has a liner in the well, the right rear has what appears to be a foam/fiberglass application that does not quite cover the entire well. I have been told that all RAV4s are built the same way. Is this so? And why the different treatment? Toyota's answer was that each area might order their cars with slight different build requests.
