Abstract
A door latch system for vehicle doors, deck lids, hatches, hoods, or the like includes a latch. The latch has a predicted life that may be based on a number of times the latch is used. A sensor that generates a signal that can be used to determine if the latch has reached the predicted life and/or if the latch is approaching the predicted life and/or if the latch has exceeded the predicted life. The system may include a controller that causes a display in a vehicle interior to display an end-of-life signal.
