  3. Just as likely to be an issue with eddy currents damaging a bearing via arcing.

    Well mine didn't have it at new, and now at 7,000Km or so I can hear the hiss as long as I've got the windows down, the VESS off and I'm in a car park next to a wall. I'll bring it to the dealer's attention at the 15K service, if only so that I have a written record of reporting the problem. We'll see what happens. No other odd sounds.... yet.
     
  5. I re-posted this in the repair issues and fixes thread for future quick reference;)

    I’ve recently passed the 5,000 mile mark on my Kona, and the sound that began around 2,000 miles has become much louder and nearly constant. At low speeds it sounds like something rubbing rotationally. At high speeds it sounds more like a whine, or a jet engine when I floor the accelerator. This sound happens on both acceleration and deceleration, regardless of the level of regenerative braking. I can even cause it to appear and disappear with variable acceleration or deceleration.

    Colin, is this the same sound that you experienced? I haven’t taken it in to Hyundai yet, but I’m going to soon because it’s starting to drive me up the wall.

    Thank you!

  8. I have been closely monitoring this situation in other owners cars, but to add perspective to the discussion I crossed 20,000 km this weekend and have not had any issues like this (yet!) Our car was an early build unit from Dec 2018
     
  9. Hmmm, interesting, my car is also a Dec 2018 build, and just over 15,500 kms (since May 1). And no issues or noises with mine either.

    15400 miles/24600 km and no noises from my transmission..
     
  11. 3000 miles and an occasional rumbling ("baseball card in the bicycle spokes") type noise when accelerating at very low speeds. Car manufactured in March, 2019. Haven't brought it to the dealer yet because I can't replicate it on demand.

    Reading through some of the comments, I do have a light sandpaper type noise at low speeds when using regeneration since the car was new. That noise has not changed or gotten louder.. I always assumed that it's the noise that the regeneration system makes as it has been there since new. It's not very loud and can only be heard with the windows down. If VESS would be on, you could not even hear it. It's not loud enough to bother me and it was there since new. Well, I turned off VESS after about 1 to 2 weeks of ownership and that's when I noticed that sound which I assumed as being normal..

    By any chance, is the dealer you used Tustin Hyunda (close to Hyundai Motors America)? I've been having a problem with a clicking noise on acceleration/deceleration similar to those in another thread: https://www.insideevsforum.com/community/index.php?threads/disappointed.6584/

    I'm worried the dealership will blow me off even with all the information I've gathered.
     
  18. Call Hyundai Consumer Affairs. We had a problem with the heating unit (no heat) and car was in the shop for more than 30 days while they sourced the part from Korea. Consumer affairs said they can reimburse us for lease payments and some other incidentals while the car was in the shop. You have to wait to bill them until you get the car back but it’s worth opening a case while you wait.

    No, I used Temecula Hyundai. Sorry to hear about that. My clicking noise is now back, although intermittent. Keep you all posted!

    No, I experienced it only on coasting to a stop, thought it was the regenerative breaking. Very much sounded like a bad bearing. Almost like a roulette table slowing to a stop.

    WHAT?
    They replaced your gearbox and motor and now the sound has come back????
     
  22. I worry that this could be a design flaw with no easy fix rather than a defective part. Either way, I hope Hyundai does right by its customers and handles this issue appropriately. So far, there’s no indication that they’ve actually concluded or acknowledged a systemic issue.

    Wow ... as a new 2020 KONA EV owner this makes me very nervous.
