Honda Jazz Sport 2007. I noticed today that when unlocking via remote fob, and I only open the tailgate, with the tailgate still open, all the locks including tailgate relock within a minute. This does not happen when the other 4 doors are open, the locking remains unlocked. I know this model has superlocking and auto relocking which activate if you do not open doors. Car battery is less than 2 years old from tayna, and I have replaced remote fob battery. Yet with tailgate open car relocks. Is this normal for this model?
