3 System Warnings

All of a sudden I got 3 warnings on my 2020 Palisade the other day. "Check forward-collision avoidance assist system", "Check lane departure warning (LDW) system", and "Check high beam assist (HBA) system" while driving on the highway.
It's little concerning I got them only 6,600 miles into my ownership. Windshield is clean, there are no obstructions.
I am almost due for a service so plan on taking it to the dealership anyway, but I was just curious if anyone else experienced these issues and what the fix entailed?

Was it raining? I get this when it rains on my G80.

also had it pop up once when a plastic bag got stuck to the front of the vehicle.

No, it was dry. And it's been coming on ever since, few minutes after I start driving and stays on until the car shuts off.

I did two weeks ago for an oil change and warnings and they told me all of Hyundai diagnostic systems were down (not sure if it was BS or not) so they did not even take a look at it. Since then I've needed the car so I haven't scheduled a new appointment.

Update: I finally managed to take my car to have it looked at. They ended up replacing the windshield camera module, then had to calibrate it. So far everything seems well.

All, FWIW, I had the similar happen to my 2020 Palisade Limited on 8/22/21, except the 3 warnings I got were High Beam Assist, Driver Attention and Forward Collision. Took it in to the dealer and here is from the tech's write up after they fixed it: "scanned vehicle for codes...found codes c180581 lkas can signal error and c160649 ecu software error...replaced front camera... variant coded and calibrated camera ... took car for test drive... front camera was working as designed..."
I was lucky they had a camera assembly in stock. Cheers. It was covered under warranty. ( 9800 mles)

Yeah, all of those things immediately point to the windshield camera (the front camera is the grille one, IMO). Wish those warnings were more complete, adding 'due to camera malfunction', or words to that effect. But now we know :).

I experienced the same issues this Friday, but I have a 2021 Hyundai Limited. The major difference is my steering wheel locked and the tires would only drive straight due to steering issues. I’m waiting for the dealership to call me and let me know what happened. Technology is great until things like this happen.

That's a different issue than above; that's power steering failure. By the way, I really doubt the steering really 'locked'; it only gets hard to move, but it should move with enough force, so you know. But yes, it's dangerous, since you just cannot steer quickly if needed, without power assist. I've read about power steering issues before, where the lady also said steering locked (but later corrected that wasn't the case), so you're not the first. Good luck.

How long did this take Hyundai to fix once you dropped your car off? I have the same problem (same three check lights on) for my brand new Santa Cruz. Only has 150 miles on it. I wasn’t able to get an appointment for 2 weeks. I assume it was safe to drive before you brought it in? Appreciate the insight.

On the original issue, I'm surprised dealers are not attempting to just calibrate the windshield camera first, before replacing anything... but maybe they did; who knows. Wonder if those affected folks ever had a windshield replaced, which would explain the issue. At any rate, it'd be nice to have the option to re-calibrate that camera from inside the car (like when replacing windshields), like with Teslas (service menu). And you can also adjust vertical headlight aim too, which is really cool as well.
