The second row seat(s) may also exhibit a rattle noise while driving from one of the seat latches without a warning message. This may be due to one of the power seat latches losing its learned home position. To relearn the home position, start with the seat down and latched. Press and hold the power return button on the seat back for at least 5 seconds. Release the return button. Wait 20 seconds, then confirm proper power pitch and stow operation of the affected seat. Road test the vehicle above 5 MPH (8 km/h) to confirm the warning light and/or rattle concern is resolved. For claiming, use causal part 7863161 and labor operations 12651D and 12651D45. If the concern persists, refer to Workshop Manual (WSM), Section 501-10B for normal diagnostics and repair the vehicle outside of this article.
