I've experienced some of the issues described on this forum such as, axle wrap, the forward "lunge" while stopped, and gear hunting. At just over 5k km's (3k miles) and it seems to be slightly better. The issues are definitely still there, I'm just not sure if they are as noticeable as when new. No leaky differential, so far. Mine is an October '17, Texas build. The fit and finish seem to be a notch above my '15 Highlander AWD LE Plus. I like my truck but I'm still waiting to see if I'll ever love it.
