On my wife's 23 Santa Fe the dash flashed a notice that AEB engaged. The car didn't actually slow down but apparently this is a thing that happens with some late model Hyundai models.
From what I've been reading some folks have had the car slam on the brakes on the interstate.
Anyone have this happen with their car, Hyundai or not?
Someone on here once mentioned that their car went into a full panic-stop over a chip bag that blew in front of the car on the highway, which is pretty much the same way chaff dropped from a fighter jet distracts missiles...
Both my 3rd gen F-150 Raptors have done that. Ford "fixed" them with a software update that has made my cruise control and Pro Power OnBoard malfunction at highway speeds now.

My '21 F-150 applies the brakes, fully, at about 5 mph after you start from a full stop. Does it about once every 6 weeks. I'm nervous one of these times I'm going to get rear ended. It's not the emergency stopping, or at least it doesn't do those warnings. I have the "auto-hold" turned on, where it keeps brakes on when you're at a full stop, even if you take your foot off the brake, until you hit the accelerator; it's like it's mistakenly putting that auto-hold back on shortly after you take off.
Not at all relevant to your Hyundai question, but sounds like more than my f150 has also had some weird "auto braking" behaviors.
I haven't had it happen in my wife's 2018 Accent (at least not yet), though we have had a few scary instances where I confirmed that the system does, in fact, work.
It's helpful to think of the electronic nannies on modern automobiles as beta test versions.
I've had several unexpected hard braking events in our Tesla Model 3 due to false positives when the cruise control or FSD is active. Keeps you on your toes.
I had a false event on my Maverick hybrid once. I was driving to work early one morning and had just pulled out into the main road. I was the only vehicle on the road at that time. It was really humid and condensation was collecting on the windshield. All of a sudden the "BRAKE!" warning and chime went off. There was nothing around me.
I figured that the condensation obscured the camera and a shadow or something caused the AEB to trigger. It never happened again.
I turned mine to "warning only" mode. I haven't had it actually try to stop the car. It does screech at me when I'm in a turn lane and oncoming cars get to close if I'm still moving.

That is the plan for our car as well.
Mazda had a recall for phantom braking events IIRC. Not on the Miatas, but on the bread and butter cars. I remember it being for the Mazda3 a few years back, but it looks like they just issued one a couple of days ago for the CX-90.
Teslas have also been known to do it although the reason is usually different, I believe it's because they get confused and think they're on a frontage road instead of an interstate. Only when cruise (or a level or two up from cruise) is activated, I don't think I've heard of it happening when the driver was in full control.

Are you riding the brake after/going down hill?
Mine only does that(21 F150) if I'm back on the brake shortly after auto hold. Something like a steep downhill stop sign where you need to creep. I'll turn the auto hold off for those situations.
My parents driveway is quite long and steep as well, I just have to make sure be going ~10ish mph before dragging the brake or turn auto hold off.

Nope. Live in the land of 0% grade. What you're describing happens when I'm backing up to a trailer, fairly frequently.
Actually did it this morning leaving a stoplight on my way into work and made the car behind me think I brake checked them (I guess I did...just not on purpose). Today it was at 7mph, I just happened to look down at dash as it happened, and didn't bring me to a complete stop, but interrupts the throttle and hits the brakes, HARD. Subaru behind me gave me a few of their thoughts and opinions through the windshield. But didn't hit me.
