Recently, Nissan reported that their Rear Door Alert Technology will be offered as a standard feature on more models, which should help cut down on potential heatstroke episodes. Developed by two Nissan engineers who also happened to be mothers, this technology reminds drivers to check their rear seats for objects or passengers when they get out of their Nissan vehicle. While other automakers may have similar technologies, Nissan is the first to implement a series of distinctive honks as the alert for this kind of feature.


Rear Door Alert (RDA) is currently a standard offering on the 2018 Pathfinder. Nissan is expanding the technology to all four-door models in the following steps:

  • For the 2019 model year, eight Nissan models, including the Rogue SUV and Altima sedan, will feature Rear Door Alert as a standard feature
  • By the 2022 model year, Nissan plans to offer RDA as a standard feature on every four-door sedan, SUV and pickup they offer

When one of the rear doors is opened and closed before a vehicle is driven, the system monitors the rear doors to ensure that they're opened at the end of a trip. If the rear doors aren't opened after the vehicle is parked and the ignition is turned off, the system emits a series of notifications. The first is a reminder on the instrument panel, and the alerts progress to a series of horn chirps. The system is easy to configure, and can easily be turned off if you wish.
