Owner report 11432408 · 2021-09-10 (September 10, 2021)
This issue is easily repeatable, when braking if you hit a bump (pot hole, etc.) the braking power is greatly reduced & the brake pedal becomes almost impossible to push down to stop the car, making it very hard to stop even when not coming to an abrupt stop.

Owner report 11421743 · 2021-06-21 (June 21, 2021)
The traction battery on my Ioniq 2020 went bad after 3 months. The diagnostic panel warned me of an electric issue and the range dropped drastically. The dealer changed the battery no questions asked. My vin wasn't part of the recall. I wonder if the recall should have included a broader range of vehicles.

Refill Coolant warning light intermittently signals EV battery coolant problem. Hyundai dealer in Fort Wayne, IN, topped off coolant. Andrew service representative was informed of two YouTube videos explaining recall due to defective coolant ASC1 that crystalizes and/or becomes sludgy.
