Ioniq scary braking problems

[Sunsh1neD4ydre4m]

I've been having some really scary issues with my 2016 Ioniq. Out of the blue, the ABS and warning lights come on, and suddenly the regen braking completely stops working. Not only that, but the brakes feel incredibly stiff and unresponsive, and the car accelerates way faster than normal. This usually lasts for about 10 miles, then everything goes back to normal.

It's really unsettling, and I'm worried about driving it. Has anyone else experienced anything like this with their Ioniq? I'm at a loss as to what might be causing it.

That sounds really unsettling. I haven't experienced this with my Ioniq, but I found a discussion where someone mentioned that if the wheel speed sensors are failing, regenerative braking won't work, and several warning lights, including ABS and traction control, might illuminate. They suggested that this could be due to issues with the wheel speed sensors.
