Toyota says in its manual to not use LTA during rain or snow. I don’t recall what it says about gravel roads, but I would think LTA is not recommended for it either.A month ago I was on a gravel road with our AWD in the Badlands and found it to be a bit squirrelly at 50mph+ with the LTA enabled. The ride quality was significantly better upon disabling LTA and choosing to guide us down that rocky dusty path manually.
Same! I was a bit shocked by just how much dust and dirt penetrates around second row sliding doors at both top and bottom. All the little nooks and pickets holding the powered slide mechanism looked like I’d literally shoveled multiple scoops of soil directly into them. Not as bad in rear deck area around the trunk, but still more than expected.3. I got a lot of dirt in sliding door tracks from driving on dirt/gravel roads in Kansas. I don't know what all places it has made it that I can't see or reach
