2020 Ioniq Hybrid brake sounds

[Arnel Pen]

My 2020 hybrid has started making a whistling noise when I brake or accelerate, and I've noticed it happens when the car goes into electric mode. Has anyone else experienced this problem?

It could be the regenerative braking or something with the electric motor. Might be a good idea to have a mechanic check it out, I've heard other hybrid owners mention the same issue.

Maybe your brakes are worn out already? Considering yours is a 2019 model, I think it's time to replace them.
