Nissan’s Rear Door Alert makes sure drivers leave no child or pet behind

‘Tis the season … for sweltering, hot days. During the summertime, it’s easy to want to get on with whatever you’re doing, just so you can limit your exposure to the hot, sweaty temperatures in the Northern Hemisphere. At the same time, it’s just as easy to forget about things you might’ve left in your car when you’re craving a nice and comfortable air-conditioned space. And that’s why Nissan will standardize Rear Door Alert (RDA) on all of its four-door models, a warning system that reminds drivers to check the backseat after the vehicle is parked. We saw the system debut initially on the latest Nissan Pathfinder just last year.

Beginning with the 2019 model year, Nissan will equip all of its four-door models with Rear Door Alert, starting with the company’s best-selling models: the Rogue and the Altima. By 2022, Nissan plans to have RDA standard on all of its four-door trucks, sedans, and SUVs.

Summertime isn’t just a peak time for the beach and barbecues. It’s also a peak time for fatalities from people unintentionally leaving children, infants, and pets in the car. To try and curtail this issue, Nissan’s solution is Rear Door Alert.

It simply alerts the driver via a message on the gauge cluster’s center instrument display and a quick honk of the horn to double-check the rear seats. It’s the first system of its kind that utilizes an array of sensors for the doors, detecting whether or not the rear doors were accessed on a recent trip, but not re-opened after said trip. Then, once the car is put into park and the ignition switched off, it sounds the car’s horn to tell the driver that they might have left something important in the back seat.

“I’m proud to see Nissan lead the way by making Rear Door Alert standard on more models,” said Marlene Mendoza, an engineer who worked with Nissan on the new feature. “What started as a chat with my colleague, Elsa Foley, is now innovative technology being adopted in more Nissan models. It is a testament to Nissan’s culture.”

“The idea was inspired when I accidentally left a pan of lasagna in the back seat of my car overnight,” Mendoza added. “The worst thing was the car smelled for days, but it made me ask myself, ‘What if I left something far more important back there?'”

During the summer, a vehicle’s interior in 80-degree Fahrenheit ambient weather can heat up rapidly to more than 123 degrees Fahrenheit in a matter of minutes. Such a climb essentially makes the insides of your car into a low-intensity baking oven. And that’s no good if the objects accidentally left inside are living beings.

More than 36 children die every year from being left in a hot car, and the number is comparable for pets left in vehicles.

With Rear Door Alert, Nissan hopes to that no child or pet gets left behind in a hot car.

Bose wants to dominate car audio, and I heard its next-gen 3D automotive speakers

Bose’s automotive audio business is huge, and it’s set to get even bigger. The company has been making big plays in car audio for some time now. The audio company works with premium brands like Porsche, building high-end speakers that allow drivers to experience high-quality audio on the road, whether they’re carting the family around in an Escalade or weaving around the highway (don’t do that) in a Porsche Macan.

But while it has a solid selection of audio brands under its belt, the world of personal audio is also evolving. Mercedes-Benz showed off its Dolby Atmos system at CES last year, and now, a year later, plenty of other brands are joining the trend. At CES 2025, Bose walked me through its current lineup of automotive audio products, as well as a sneak peek of what’s to come.
Immersive audio
The big trend in all areas of personal audio right now essentially boils down to supporting 3D audio formats like Dolby Atmos. Consumer home theater products are increasingly offering up-firing and side-firing speakers that can bounce audio around the room to simulate height and surround effects, while headphone brands are increasingly developing spatialized audio tech that can convert stereo audio into simulated spatial audio.

You Asked: What’s the most impressive thing you saw at CES?
You Asked CES Editors Cut

On today’s special edition of You Asked, we tracked down each of our editors and put them on the spot to find out what they thought was the most impressive thing they saw at CES 2025 in Early January. Let’s find out what they had to say.
Panasonic Z95B

There’s been some really cool TV tech at CES, but the thing I’m most excited about is the new Panasonic Z95B. Instead of the regular OLED display structure we’ve seen in recent years with MLA technology, this uses a four-layer panel structure. It features individual red, green, and blue layers (two of the latter) for the emissive light.

Volvo CTO Anders Bell chats its new do-it-all tech platform and future EVs
2025 Volvo EX90 front quarter view.

Volvo is at an inflection point. The company has finally launched the new Volvo EX90 -- it's long-awaited flagship electric SUV, designed to take on other premium large SUVs like the Rivian R1S. The new vehicle offers Volvo's signature Scandinavian style, but with modern features and Google's Android Automotive software.

Beyond being its first major electric SUV release, perhaps more important is the fact that the EX90 also represents the launch of Volvo's so-called Superset platform. Essentially, Superset is the Volvo-designed tech stack that is supposed to be used on all of its upcoming electric vehicles, containing all the modules and software necessary to power a built-out next-generation lineup of EVs.
