2025 Hyundai Ioniq 5

The car will not allow me to use the LKA feature while wearing sunglasses. It allows it, but it gives nonstop alarms and warnings, because it can’t see my eyes? It makes the feature nearly unusable, which takes the safety feature away from the user. Even with the warning turned OFF, it still beeps. There’s literally a setting to not activate the warning, it still does it. I’ll attach a photo of the setting turned OFF. And yet it still beeps constantly. I live in Los Angeles and the sun is bright here. There must be a fix for this?

FORWARD ATTENTION WARNING When driving, the vehicle randomly and repeatedly warns the driver to pay attention to the road even when the driver is facing forward and paying attention to the road. The system will also randomly and repeatedly alarm, disable cruise control and apply the brakes even when the driver has both hands on the wheel and is facing forward. This has nearly caused crashes. Hyundai states the system is working as designed and suggested: 1. Driver is too tall for the system see my eyes. 2. Do not wear prescription glasses. 3. Do not wear sunglasses. Research has revealed hundreds and hundreds of similar complaints. Hyundai has issued a technical service bulletin 25-GI-001H stating there is nothing wrong with the vehicle and states drivers who are tall, short, wear glasses will experience this.

I was driving the car on [XXX], and I got a battery management system warning light (DTC P0B6D00). When I got home, my car wouldn't charge. I took the car to the dealership for service for this light. Without the ability to charge and battery issues, it affects the drivability of the car and the car may stop if there isn't enough charge when driving. The problem has been reproduced by the dealer, and there was an attempt to replace a part, but it caused the light to go off 3 more times. The car has been at the dealership since June 23rd, 2025 without resolution. There were no other warnings or messages prior to this failure as the car ran without any issues.

I purchased my 2025 Ioniq 5 Limited less than a week ago and have found that adaptive cruise control and lane keeping assist systems are essentially non-functional because of repeated false warnings from the Driver Attention System. Purported to monitor the driver's attention by watching the eyes, this system clearly doesn't work well enough to serve it's purpose and, in fact, causes unnecessary distractions and unsafe conditions with repeated and frequent false positive warnings. The first warnings caution the driver to keep his/her eyes on the road (my eyes are on the road) and escalate to point where ACC and lane keeping assist are turned off. Since the drive attention warnings cannot be turned off when in ACC with lane keeping assist are active, the only recourse is to turn off lane keeping assist, making this system essentially non-functional and useless. Note: Hyundai is aware of this and has issued at least one TSB advising that some eyewear may prevent the system from functioning properly and that this is considered "normal" leaving the driver to find suitable eyewear. I do not usually drive with sun glasses and having the car manufacturer suggest that their system may be impacted by my prescription glasses (which I do wear while driving) and the fix to this potentially dangerous situation is to replace my glasses is ludicrous. I have also done limited testing without my glasses and find that it has no impact on the false warnings. Per Hyundai's TSB I have made sure that my driver's position is such that the monitor's camera has an unobstructed view of my eyes and is not blocked at any time by my hands or arms while I'm holding the wheel.

I notice a strange pulsing/hesitation when accelerating at partial throttle (maybe 10-25%) between 60-65MPH. It's quite alarming, because it feels like the electric motor is cutting out momentarily. I notice the same pulsing/hesitation during regenerative braking at the same speeds (as with the acceleration, it is only noticeable at partial regen). The dealer confirmed that they've noticed the same behavior on other new Ioniq 5 vehicles, but they don't have a fix. I don't know the safety implications, but I worry about the electric motor cutting out and affecting my ability to control the car during acceleration or regenerative braking.

I leased a 2025 Hyundai Ioniq 5 with the exact same issue. The VIN is [XXX] My new Hyundai Ioniq 5 is having the same problem again! Vehicle will hesitate/shudder and pulsate at highway speeds. Between 57mph and 78mph seems to be where I can feel it the most. This happens on all drive modes and with or without brake regeneration turned on or off. Nothing seems to make it worse or better. Here is an example. If you are driving 65mph on the highway and holding your speed steady, the car motor feels like it's cutting in and out. Juddering forward and back. If you accelerate a tiny bit, it gets ever worse. It feels almost like the input signal from the peddle is choppy, causing the car motor to judder. It is a forward to back motion. Not a vibrate or side to side motion. Dealership said basically they'll keep the car and possibly we can hope Hyundai will lemon law me out of the car.

I took the car to the dealership where they confirmed they could feel it too. They ended up rotating my tires... Said that's all they can really do because Hyundai doesn't have anymore information. They basically said sorry but they can't help.
