Noticed something since getting the car, sometimes when I'm at a lower speed like 30mph or something random and have my foot off the accelerator I'll have some vibrations that come from the rear and make noise. It feels like it vibrates the whole car and then disappears. I have no idea what it could be or if its something normal with AWD in these cars. Has anyone had a similar issue? Apologies if I'm not explaining it the best. I did some research and on other lexus models it was suggested perhaps it could be transmission software that fixes some things or even the fluid changed. Its only happend a few times but is very strange to me. I'm on stock awd suspension stock wheels.
