My 2014 SR5, built around December, has a bumpy power drivers seat. About two thirds of the travel backwards, you feel a distinct "bump-bump." Same going forwards. My dealer orginally thought it was some interferance with a seat belt anchor and they made appropriate adjustments. It has returned, and is now a bit more noticeable. I'll have them work on it again when I get a chance to take it in, but I'm curious if anyone else had this issue? Others may wish to check their seat by moving it all the way to one extreme, and then the other. Thanks.
