We’ve spent a lot of time here and on the radio show reminding people not to leave kids and pets in hot cars, so Hyundai’s recent announcement about its door-logic Rear Occupant Alert system got our attention. The automaker says the feature will be standard on most of its vehicles by 2022. (Hyundai also has a sensor-based Rear Occupant system that it says will be available on more models in the future.)

The announcement came on National Heatstroke Prevention Day when Hyundai also praised the National Highway Traffic Safety Administration, Congress and Consumer Reports for raising awareness of rear seat reminder systems. Hyundai says making these systems standard equipment will help prevent child deaths from heatstroke in vehicles.

Two Hyundai models are available today with door-logic ROA as standard equipment: the 2020 Santa Fe and Palisade. Both of these SUVs have the Ultrasonic ROA available as an option. Coming later this year to dealerships, the 2020 Sonata will feature standard door-logic ROA. The 2019 Santa Fe has the Ultrasonic ROA feature available as an option.

"Heatstroke in vehicles is preventable and we are doing our part to prevent this," said Mike O'Brien, vice president, Product, Corporate and Digital Planning, Hyundai Motor America. "We have great systems that use both door logic memory and motion sensors to help prevent children and pets from being forgotten in the car, but it also helps in case children accidentally lock themselves in."

Hyundai currently offers two types of ROA systems to help prevent these tragedies from occurring. The ROA door-logic system detects if a rear door was opened or closed before the car was started, then reminds the driver to check the rear seat with a message on the center cluster when exiting the vehicle.

The Ultrasonic ROA has the door-logic technology and an ultrasonic sensor that helps to detect the movements of children and pets in the second-row seats. If the system detects movement in the second-row seats after the driver leaves the vehicle and locks the doors, it will honk the horn and send an alert to the driver's smartphone via Hyundai's Blue Link connected car system (if equipped with Blue Link and the Blue Link service is active).
