A vehicle system includes a closure panel, one or more panel actuators operable to move the closure panel during opening and closing and to move the closure panel at a closing speed during closing, a latch operable to lock the closure panel, and a controller electrically connected with the panel actuator. The controller is configured to selectively adjust the closing speed of the panel actuator(s) on the next closing, based on past opening and closing of the closure panel. Loss of speed and higher current draws are equated to mechanical interferences in the closing and opening of the closure panel. The speed, voltages, dynamic braking, target speed, and obstacle thresholds can be adjusted in way that facilitates closing the closure panel without the need for servicing.
