Low frequency hum when accelerating? Is this normal?

The point of an EV qualified dealership certifying the problem is to create a paper trail. This is your only route to warranty coverage if a failure takes you off the road.

My experience leads me to believe Hyundai/KIA is denying initial claims and hoping the second owner sells off the vehicle.

 

Have you made enquiries with your dealer yet?

 

Hi, I'm new to this forum but I signed up because I'm having gear-whine type noise in my 2019 Kona EV, recently purchased used with 47,000 miles. Bought as a "certified" from a Hyundai dealer. Everything else is fine and I love the car but that noise seems excessive, especially since I just drove a rented ICE Kona which was much quieter. Perhaps surprisingly, it seems to be louder at the rear of the car but I know all the hardware is in the front.....I'm planning to take it to the dealer to inquire as soon as possible. Threads I've been reading about motor and drivetrain replacement sound scary, I expect the dealer will resist that mightily!

 

Mine didn't resist at all. It's a well known and documented issue and the resolution is also well known and provided for. If your dealer is resistant try to find one with experience swapping drive trains.

 

Through this

Through this forum I was able to track down another dealer with experience when my dealer was stymied. It worked for me.

 

Well, although planning in general is a good habit there's no point in getting worked up over speculation as I don't think anyone has been turned away. Once they read the TSB and make a few phone calls, they will realize that this is a way bigger issue than they had imagined. What is a more likely scenario is that it could takes weeks or even months to repair. They should provide you with a loaner car for duration.

 

That's a generous understatement.
