I am thinking of trying the box in the parking lot stunt to find out in a controlled environment what different factors affect the operation of this system. Will post the results when I have done this.

Regarding the HDA cruise activation you know you can set the following distance which in turns controls how soon the system will brake?
My Palisade performs flawlessly in cruise control and it is set to the farthest setting.

The palisade if my first vehicle with a FCA and I too wanted to know if was working correctly. Before seeing this thread I put a piece of rolled up carpet out in my cul-de-sac at night which never has any traffic. I placed the roll of carpet vertically and it was about 5 feet tall, I thought this would somewhat replicate a pedestrian.

This did not work at all. Either the FCA is more intelligent than I thought and really does pick up on the silhouette of a person or my system was not working. I also never did hit the carpet, but swerved at the last second to avoid it. So maybe it noted the evasive steering at the last second and did not activate, but I still thought it should have started a warning as I was only several feet from the carpet and it would have had to really slam the breaks very quickly. I was doing this at about 15 to 20 mph

So I did see one of the above videos where they essentially made what looked like a person leaned it against a box and that obviously worked, so anybody trying recreate these situations may need to get more creative than just stacking some items.

So going back to the situation above, I was losing some confidence that my system was working. I just got back from a trip to the Smoky Mountains and did have the FCA activate in a needed situation. I was driving with my wife up to Clingmans Dome in the Smoky Mountain National Park and anyone who has been on this scenic drive can probably see where this is going.

A vehicle, that was in front of the vehicle in front of me, came to an extremely abrupt stop, which obviously caused the vehicle in front of me to slam it's brakes. All of us were probably watching the scenery at this particular area more than we should have been, and I caught out of the corner of my eye that the car directly in front of me was at, or almost at a complete stop.

My foot instinctively was going to the brake when the FCA kicked in with an audible alert and i'm pretty sure it was starting to automatically brake. But as soon as I slammed my foot on the brake it felt like it gave the braking control back to me. Needless to say all ended well, and I felt the system did what it needed.

My observations so far is that Hyundai may have really tried to eliminate the system false triggering and the system seems to really hold out as long as possible before activating. It see that if the system gets even a slight inclination that you are slowing, absolutely BARLEY touching the brake, it really holds out as far as activating.

As far as the dealership not being very astute on this technology... that is no surprise to me and not unique to Hyundai dealerships. I have owned many makes of cars both foreign and domestic and have always been disappointed with the lack of knowledge of the technical aspects of these newer vehicles.

I anxious to see if anyone can do some successful tests of this system.

Well I did the card board box atop a styrofoam cooler crash test at 25 mph. I discovered a few things: First the experience of deliberating crashing into something was strangely exhilarating and quite panicky at the same time. The styrofoam cooler met its demise and the card board box ended up on the hood. The FCA did not stop the car or give any indication that there was an obstacle in the road ahead. That being said I know from two real world experiences that the system works and the wife and I were spared possible collisions. That is good enough for me until such a time that a real world event convinces me otherwise.

Thank you for running the test, as disquieting as your results are to me. Your faith in the real-world behavior of your vehicle is touching, but I'd really like to know 1) how the system is supposed to work 2) why it appears to sometimes and not others and 3) what I can actually expect in the real world.
I bought my Palisade largely on the basis of its safety features and it seems to me that Hyundai owes us more than marketing hype and random operation of the FCA.

That's why I posted this thread.
My expectations were not really to see FCA "Assist" with braking when I intentionally speed close to an object, I only expected a "Warning" at least, as the manual suggests.

Thanks for sharing your test observations Sterling.

So I was just browsing the manual and it clearly states that there is a built-in pedestrian recognition system. So you can't just use a square box to test this. It has to be something that looks like a human with a normal "body structure" (those words are in the manual, they're not my words). This explains why the video posted earlier in this thread had a cardboard cut-out of a human being instead of just a box.

Now that doesn't explain why it doesn't try to avoid the box as if it were another car, but I think (again, by reading the manual) that the object has to be moving to be recognized as a potential vehicle to avoid. So a box is not seen as such (because it doesn't move) and it's not seen as a pedestrian (because it doesn't look like one). Instead, it is seen as being part of the landscape.

In other words, there's some AI built-in that tries to recognize obstacles to avoid false positives that would make the car slam on the brakes for no reason. From that stand-point, it makes sense: it would be just a dangerous to slam on the brakes for no reason for the people behind you. But it also means it's not going to stop you deliberately driving into something (like a box).

Just my guess as to how this works, based on the wording in the manual.

Now that makes reasonable sense to me.

My only concern is if the "AI" starts to talk to me using my name I just might have to put a bullet in the dash. Smiling here.

What's crazy is it works perfectly when you got it in hda cruise mode. It will come to a complete stop if you let it. Scary as hell though because it stops later than you'd expect.

What about REAR collision avoidance? Everything I read seems detailed when it comes to front collision avoidance but what about the rear? All I can find is that it will apply the brakes if a pedestrian happens to be walking behind the vehicle or if you are backing out of a parking spot and a cross-traffic vehicle is sensed. Aside from seeing it in the camera will the car sense a stationary object and activate braking to prevent you from backing into a post, guardrail or something other than a vehicle or person?

That feature works flawlessly on my Palisade Limited. It will keep me from backing out if there is anything coming from either direction or if there is a pedestrian in the way.

Update on the FCA: it continues to operate for people turning out of my lane, either left or right, if they have not cleared the lane and I have not braked. It has activated twice now for cars in my lane. Whether it activates for cars directly in front of me or not is entirely serendipitous. I do NOT rely on it at all.

Update on cruise control. Pali does a fantastic job of maintaining distance between me and the car in front. The system is so good that you can use it in stop and go traffic on the highway. Not long ago, I was on Rt 128 (AKA I-95) around Boston. It would take the car from 60+ mph to a complete stop and then start up again from 0 mph to whatever the traffic speed (or my setting if lower) with no intervention whatsoever from me. Impressed.

I got my Palisade limited less than a week ago and quickly started realizing that FCA did not work at all. There's been plenty of times I would have rear ended the car in front of me had I not braked or swerved and never did the FCA come on. I've only had it come on when a car up ahead turns right but it seems like the forward sensitivity is not working as it should. Funny thing is like others have posted, when using SCC the camera/radar do a stellar job at slowing/stopping if needed so not sure why the FCA is not working in a similar way. I also tested using a large cardboard box and ran right through the thing. I will be buying a life-size cardboard human figure to see if it works with that but I'm extremely disappointed as this was one of the key safety features that were important to me and it's supposed to work a lot differently than it does according to the manual.

The cardboard box isn’t a good test. The camera looks for patterns: it looks for a human body shape for pedestrian detection, for example. I’m not saying you don’t have a problem with yours, but the algorithm is more complex than it seems.

Since my post above...
Something I have discovered that may be of use to other Palisade owners:
Since I first drove my AWD Limited in July, I have not thought that the FCA (forward collision avoidance) was operating properly: it worked when a car stopped abruptly to turn left or right but not at all when a car in my lane stopped short. Early on I had it checked at three different service departments, heard a lot of BS from service managers about my expectations being too high, and stuff that flat contradicted the owner's manual. Letters to corporate yielded nothing more constructive than "try another service department."
Recently it occurred to me that maybe somehow the license plate was blocking the sensor below it, even though it was in the "factory" license plate holder. The hypothesis grew out of the fact that if the system reacted when the "collision object" was to left or right but not in the center that could be either obstructed view or faulty sensor. At one of the service departments the head mechanic who clearly cared said he had tested the sensors six ways to Sunday and they were OK.
So, yesterday I removed the "factory" license plate holder and installed an adjustable one, which I mounted roughly 1.5" higher, nothing sticking down below or even to the bottom of the bumper. Today in traffic, the system activated three times as cars stopped short. I can't PROVE that was it, but it sure seems that way.

I should point out, despite my experience, someone who posted in the Facebook Palisade Owners' Group whose vehicle has neither front plate nor holder is also seeing his FCA failing to warn him. There was in addition a woman who was in an accident when another car turning in an intersection hit the front of her Palisade. It is not clear whether she was moving faster than 5 mph however when she was hit.

That’s probably me in the Facebook group. I have no plate or holder and have been very close to rear ending cars ahead of me and the system did not activate. It only has done so when a car is in my lane turning right or left and not cleared the lane yet.

It doesn’t work worth a damn in my experience. Minor rear collision where it absolutely should have worked and didn’t resulted in $5k worth of damage and parts on back order for weeks. No audible warning and no attempted braking. Going back to Volvo when this lease is up.

I have a 2012 MDX and considering Palisade Limited. The MDX has a forward collision warning, but does not stop the car totally. The biggest issue is the sensor is in the grill and it fills up with snow and slush often, and disables the system. I believe the Palisade is a 2 way system, a camera in the windshield and also a radar sensor in the lower grill. Has anyone had experience with this being blocked with snow etc and disabling the sensor system?

It’s a 2 sensor system but it’s not working for me and it seems like others have same issue but haven’t really realized it’s not working as one would expect. My sensor is not covered in any way nor do I have a front license plate and I’ve had a couple close calls where the FCA it should have alerted but nothing

can you share some detail as to the 3 times it has worked with cars in front stopping short? Like how far ahead from you and did they suddenly slam their brakes or did they just come to a quick stop and you didn’t slow down?

Of those of you saying fca didn't engage when a car stopped in front of you, were you applying the brakes, the gas, or coasting with your foot off the pedal when you felt it should activate but did not?

So, in the last month or so, I've had the FCA warning twice!
First time was when a car in n front of me was taking a left and I went too close before it completed it's turn
Second when i was in bumper to bumper traffic on a highway, the vehicles started moving so I accelerated to a decent speed but in a few seconds the vehicle in front of me stopped all of a sudden and I got a warning.
Overall, looked like it worked in both The instances that I expected it to work.
Haven't tried with a pedestrian so far ;-)
