Sad to learn this, especially so since we’re looking for a 2025 Ioniq5 Limited currently and without results. I would think you‘re doing the right things to escalate this issue. Some of my thoughts:
1- Sales staff will never be helpful in this situation…nothing to do with them or their expertise the latter of which is solely about closing a deal.
2- Service can only do what they did: replace parts/assemblies/components. Once they’ve done that they’re at the same mercy as you are with design limitations and software issues all of which are manufacturer-based.
3- I suggest keep plugging away at Hyundai, frequently and to higher levels. There are other threads in this and other forums with suggested emails and phone numbers…Search is your friend here.
4- NHTSA is also very appropriate but they will act only if there is a sufficient (whatever number that is) number of complaints about a give item. They do not typically respond or even get too excited over one-offs. This means that others experiencing the same problem have to file an NHTSA complaint too, and that’s where a forum posting can help.

Good luck with this…has to be very annoying.

 

Also look into the Lemon law if you have one in your state, if you cannot get this issue resolved.

 

I'm in the same boat. 2025 Ioniq 5 and cannot use cruise control because the FAW does not work.

Hyundai has a Technical Service Bulletin 25-GI-001H that explains the problem in more detail, but offers no solutions. I've spoken to HCCC and HCCM on multiple occasions and they are not willing to do anything. The most they offered was $150 gift card which has to be a joke.

Apparently if your are short, or tall, or wear prescription glasses, or the sun is in front, or the sun is in back, the system does not work. Hyundai does not care.

You can call Hyundai, but HCCC will give you the wrong information and HCCM will lie and say it "works as designed."

I'm seriously considering suing in Small Claims Court for $3000 for loss of Cruise Control. Don't know if I would be successful.

 

I saw another post with a possible hack from John_5534. After reaching a certain speed turn off Lane Assist and it will allow Cruise Control to work. I haven't tried it but maybe you have?

 

Would Lemon Laws in your state apply? Buyback from Hyundai? Small claims court as you suggest? Bad social media reviews (assuming you’re an “influencer” as all others don’t count)?

 

The Lemon Law should apply. But at the moment I'm in a stalemate with Hyundai for this issue. They say the vehicle has to be at the dealership to start the Lemon Law process. Massachusetts State law does not require the car to be at the dealership. I think this is just a tactic to make the process more painful. I told them if they loaned me a car, I could put my car at the dealership. They said it was up to the dealership. It is a mess.

I may try small claims court. Even if I win, I don't know if that will move Hyundai to try to address the issue, but maybe.


Media reviews would only matter if you are someone like the Ioniq Guy, but I might try putting some up anyway to see what happens. Thinking of snarky like "Hyundai Programmers are Idiots" and give several examples. Snarky content seems to get more views.

 

Lemon Laws are state relief administered by the state following state statutes. Dealerships can assist but really have no say in the process. Sometimes the threat of Lemon Law will entice a dealer to acquiesce to some level of consumer request such as your thinking about a loaner. From what you’ve outlined, I see no downside to initiating a Lemon Law buyback, and until adjudicated does not affect any of the other areas of redress open to you. Surely a PITA though, but hey, the car should work properly too.

 

Well Said.
I was hoping that once I told Hyundai wanted to do a Lemon Law Buy Back, Hyundai would give me better technical support. That did not happen. They continue to say that 1) the system cannot be fixed, 2) the system cannot be turned off, 3) I cannot be compensated for the loss of cruise control (although they recently offered me $150 like I'm some kid with a paper route that thinks $150 is a lot of money).


I did buy a device to measure the IR transmittance of my prescription glasses. My glasses seems to be at about 80% IR transmittance (950nm) which is much better than the 42% reported in the TSB that Hyundai provided. Also, if I hunch over and put my face in the camera, the system works, suggesting my glasses are not that bad and there might be other issues, such a height or camera angle.

I do think FAW systems are important and I'm glad Hyundai is working on them. But this one seems to be poorly implimented.

 

I've been reading through this blog and several things come to mind.
First, a car used to be a instrument to get you somewhere, with the driver's full attention doing the driving. The flood of convenience built into today's cars leads me to the final question.

Second, if we are to be so much guided and prevented in our vehicle's, why not go straight to autonomous riding, and then the car manufacturer can install Late Maschine in cars and I'll be thrilled.

My final muesing, what will these goddy two shoes car be like, when they are 20 years old, like my present one. Will anybody be able and allowed to drive One of these, anybody be able to maintain by paying for upkeep, anybody willing like me to perform upkeep , not being a scientist .???

I'm slowly getting an incling, why there has been a building protest about the Nanny State.

If new cars encounter unsolvable problems with bells and alarms, what will live be like when these models hit 15 or 20 years old.

Maybe the future belongs to the electric scooter 🛴???

 

There is a strong tendency to frame issues into a certain window. Some times that works, some times that is misleading.

Cars have been adding automation for decades. Automatic transmissions, Automatic chokes, Automatic timing, Electronic fuel injection, closed loop fuel/air mixture ratio adjustment. Most of these have made cars more reliable, not less. People tend to forget how old carbureted cars used to be and that they wouldn't run well. Cold temperatures made them hard to start. Now automatic systems adjust the car to keep it running well.

Driver aids will likely be the same, although at the moment they are not bullet proof. Cars being able to maintain a constant speed while adjusting for traffic should be a lot safer and convenient. Cars that can keep themselves in their own lane, should be a lot safer and convenient. Cars that brake automatically for obstacles, should be a lot safer.

I don't think adaptive cruise control is any more indication of a Nanny State than is an automatic choke. It is, or will be, just a better technology that doesn't wear out any faster.

But for now, my frustration is the FAW does not work properly. That is not a Nanny State issue, it is a Technology issue which will be fixed at some point.

 

Thank you. Agree that I'm used to both Cruise and Lane Assist and both are helpful. So, on cloudy days with no sunglasses, both can be used I think? If they told me that before I bought the Tucson, I wouldn't have believed it.

 

So I've struggled with the Forward Attention Warning (FAW) system since I owned the vehicle, a couple of months now. This has made the driver's assistance system pretty useless for me, as I can't have smart cruise control on along with lane following assist. As many of you know, when this triggers it sounds an alarm, shows a yellow warning ring on the driver display, then eventually a red eye symbol, then it shuts down all driver assist (smart cruise control, lane following assist).

I have my hands at 4 o'clock and 8 o'clock, definitely not blocking the camera's view of my face.

I've tried adjusting my seat and steering wheel position, but that doesn't fix the problem.

FAW triggers more when I'm wearing sunglasses, less with my regular glasses and still triggers when I'm not wearing glasses at all.
It seems to me that the problem is more related to the lighting conditions than if I'm wearing glasses or not, as sometimes with my sunglasses on it doesn't trigger for quite a while (e.g. 30 minutes), and other times it'll trigger every few seconds with those same sunglasses.

I've spoken with my salesman, who didn't help at all.
I've taken it in for service, where I easily replicated the problem. They replaced the in-cabin camera, but this made absolutely no difference. They were at a loss as to what, if anything they could do to help...

I've reported the problem to the National Highway and Traffic Safety Administration, as well as to Hyundai... I've yet to receive a response from either.

This problem is not only distracting and frustrating, but removes a feature from the car that I valued quite a bit when I'm on long drives.

I have the same problem with my 2025 Tucson. Like you, I've tried to adjust the seat, wearing glasses or not makes no difference. I had a 2022 Tucson that was a dream to drive. The HDA worked perfectly, was great on the hiway or in traffic. This 2025 is undrivable!! No matter what I do, I've turned the FAW off in the settings, moved the seat, adjusted the steering column up or down, nothing corrects the issue. The dealer is there to sell a car, pretty much after that they really don't care. Hyundai needs to make some kind of fix, many people I've talked to and so many people in these forums have the same issue. It's Hyundai wide across all makes that have these eye following cameras. Lately, I've been seeing some articles questioning the safety of the IR camera that shines in our eyes while driving. I need to do more research on that subject. Regardless, the FAW is a real problem that need to be addressed by Hyundai.

I'm having the exact same issues with my Ioniq 2025 XRT that I leased a month ago! I've been thinking that I was doing something wrong and tried adjusting everything to no avail. It happens during the day, at night, with sunglasses and without. This is one feature I was really looking forward to as I have several road trips planned. In fact, I found this doing some research b/c I'm about to leave on a 1,400 mi trip

What a disappointment...
