I wanted to pass along something to everyone about a repair I just had completed under warranty. In talking with the dealer the Hyundai techline told them that this was the first that they have heard of thus particular issue. This is on my 2017 Ioniq SEL (U.S.).
Currently I have 34,000 miles on mine. But somewhere around the 12,000 mile mark I started noticing a rather obnoxious squeaking noise related to the brakes. When this first started it happened so intermittently that I did not bother bringing it in to the dealer. I could not duplicate it on the regular so it would have gotten the dreaded "unable to duplicate customer complaint at this time, vehicle performing as designed". I've typed that enough times during my dealership career, definitely didn't want to see it come back my way.
After say 10,000 more miles I was able to make it happen more often then not when pushing the brake pedal to take the car out of park. It would never make that noise if it was not in Park. Braking always seemed to function properly. As I am apparently a glutton for punishment the noise had not gotten nearly annoying enough for me to have it looked at yet.
So 10,000 miles more and the squeaking would now happen everytime when shifting out of Park. And it would also happen when pushing the pedal to start the car, and also with the car off and just pumping the brake pedal.
I brought it to the dealer last week. It ended up being a phone call to the tech line. Initially they were told to go through a 15 page long procedure which ended in a brake system bleed. Noise was still unchanged. After that techline advised them to order up and install the Integrated Brake Actuation Unit. I'm told by the dealer that this ended up being a $2000 part. Flat rate time was right about 2.5 hours, though since no one at the dealer had ever done this repair yet it took them the better part of the day.
Just wanted to post this in case anyone else run into it and the dealer either can't duplicate it, or has no idea how to get it fixed.
My Ioniq is my office and I usually drive around 30-35,000 miles per year. I would assume I put it through much more driving than alot of people do in 3 years.
For the noise itself it can be heard both inside and outside of the car. It comes from the area of where the master cylinder would be in a standard brake system. It is definitely not something you would confuse the brake pedal squeaking with, and not like a brake pad squeaking. More like the insanely annoying squeakers in dog toys that I refuse to let my dogs play with.
If anyone is needing it I do have the techline case #.

Yup it did fix the problem. I never got any exact reason why it was happening or how. But replacing the Brake Actuation Unit stopped it from happening. And there isn't any different feel to the brakes or any other noticable difference other than that insanely annoying noise is gone.

I've the exact same problem. I haven't notice it till recently around 30,000 miles. I can hear it half of the time when I press the brake pedal to start the car of to shift the gear out of Park, exactly the same symptom. I would be appreciated if you can PM me the case number. Thanks.

Just got the paperwork, my dealer said the noise come from Shifter Lock Solenoid. I'm not so sure if it the same thing as integrated Brake Actuator. Any idea?

the shift lock solenoid is what stops you moving the gear leaver out of park without your foot on the brake

the integrated Brake Actuator if the unit behind the brake peddle that give the resistance you feel when the car is regen braking and also when you push further down on the brake works the mechanical brakes the same as normal cars

mines currently in for its 50.000 mile service.
I mentioned the noise and iv just had a call to from them to state my INTEGRATED BRAKE ACTUATION UNIT requires replacement.
As it's around £2000 there waiting on authorisation.
As well as the noise iv noticed the brake peddle has become far to soft for my liking which they day is the same issue.

And the specialised parts for the Ioniq seem megae expensive. Best to only keep the car for the length of the warranty.

my car is 60000 and it is a ioniq 2017 blue. I have the same problem, dealership said it cost me 2200 dollars for replace the IBAU and I paid 170 for just diagnostic. Big scam.

Let's hope this is not just a defective oil seal because of using the wrong type or assembly fault. Maybe get hold of the old unit and investigate the underlying cause of the problem.

What would be the normal lifetime of the unit under normal conditions? Wouldn't this be an argument to put in at least a partial warranty claim?

And if the customer does need to pay. Why not repair the unit instead of getting a blinking new one to reduce the cost.

I just got the similar repair done on my 2018 Ioniq SEL 28 000 miles. I have been complaining about the popping noise from my brakes for over a year. When slowing down (not a harsh braking) there would be a single pop or multiple pops .... you never know. One ignorant mechanic told me that this is normal operation of the system. I told him, I don't think so, why would hyundai built some annoying popping brake system. Besides I drove other Ioniqs and there was no issue.
So they replaced IBAU - finally

I have one more issue still not resolved. Time to time I have very bad grinding noise when turning the steering wheel. It comes and goes. I have never been able to show that to mechanic in the dealership. But other mechanics experienced it and also the Service adviser by the dealership. I told them, next time , the sound is there, I will drag the mechanic inside my car.
When the grinding is really bad, it sounds like a sand between two metal plates. Sometimes it is more like squeaky noise.
For now they replaced the clock spring, but they admitted this may not resolve the issue. I live 2 miles from the dealership so next time I drive there and drag the mechanic inside the car.

$3400 was the bill under the warranty for IBAU replacement (brakes) and clock spring (steering wheel)
