High-Pitched Motor Noise

Oh wow,
That’s a larger hit than I assumed, especially considering how scarce these things are. I even had thought that one might even be able to sell for a profit if Hyundai doesn’t pump them out fast enough!

That’s great to know though, I appreciate the information! I haven’t seen Bjorn’s videos yet, but I plan on it! I saw a few Soul videos from other sources and it does look fantastic.

I wish you both nothing but the best, and hopefully a better experience this time around!

It is quite a hit, but it is a 2019 with 2020's coming and now BC has the $10,000 worth of rebates compared to the $5,000 when we bought. So I guess the dealers have to factor in those things now.

 

About 3400.

 

I'm sure you have tried this, but I noticed some clunking after about one week back in January, I assumed it was rust or grit on the pads, so I found a stretch of highway with no traffic and sped up to highway speeds then slammed the brake. This is an old technique we used to use way back when to break in the brakes. It took care of the noise. Since then, I have selected regen level of only one, and use the brakes to stop. Since the brakes use regen most of the time, they don't get worn, but do come on for the last couple of kph and that seems to keep them clean. Haven't had a problem since and I am sure I am not wearing out the brakes. Just a thought, don't want you to leave.

 

Believe or not 10K loss is not a worst case scenario. The crappy part is that CJC as an early pre order customer in BC took a immediate hit in value as soon as the additional $5000 federal rebate came into effect in May. The dealer has to sell that vehicle as used and as such its minimum value depreciation is at least 10K(both federal and provincial rebates) below MSRP +/- any buyer premiums or discounts that may be negotiated on either side. I am actually surprised the dealer did not ask for more wiggle room (assuming we are talking a about a 10K loss after the provincial rebate). If I was looking at a used Kona I am not sure why I would want to pay over MSRP - grants and rebates vs hunkering down to wait and ordering a Kona below MSRP and likely getting the benefits of all the new car rebates, warranty etc. The only way I could see getting that 5K in lost value back is possibly selling privately or to a dealer in province such Alberta that has no provincial rebate.

 

The hiss/squeal on my car started right after I got new tires (abt 500 miles). It was hard to diagnose, because it did not change with braking, speed, etc. Last week I had to do a HARD stop (train). Since then the squeal has been reduced. Not eliminated, but reduced. Of course, I may be wrong in associating these events with the noise.....
Does any explanation fit these observations? Thanks.

 

Yes, I saw that thread, it is very unfortunate. I am not sure how any one could have foreseen how or what the federal government would do or how one can effectively plan their vehicle purchase and predict the political whims of the government.
In the end the "hit" is only relevant if you need to sell early otherwise if you keep the vehicle long enough it does not really matter as the ravages of general depreciation will equalize all.

 

Can you please post the picture of the plug.Did you access it under the bumper,or from under the hood? Saw a picture posted by someone else,and couldn't figure out where that module was.New here,can you DM people? I don't like the VESS,and wished we had the Euro.button to turn it off/on when legally required.

 

I thought I had already mentioned the info was posted by a US owner on FB some months ago. North American cars are missing the switch but the wires are present. It's a matter of pulling out the switchblock and tapping into two wires with a pushbutton and resistor. I can't even get the damn thing out of the dash but want to eventually build an add-on circuit to automatically disable VESS and LKA 5 seconds after startup.

 

I thought i read, there is a plug at front of bumper.

 

What about Engineering Mode? Is there not a parameter there that you can set?

I am OK with the reverse one, but wish the forward one would stop around 10 km/hr, or be totally silent.

 

In a few years, as EVs grow rapidly in numbers, we're going to have a new urban cacophony. The Kona at least has a mild reverse alarm but the other day I heard a Leaf with an imperious and grating beep. My worst nightmare is coming true as parking lots are now filling with beepers as well as VESS, along with those cars that really don't need to honk when locked.

Eventually the pendulum will swing back, one hopes, and we will reject unnecessary noise.

 

I’ve checked engineering mode and can’t find any settings for VESS

 

Alright so I joined this forum to specifically follow this thread as we've had our Kona EV for less than a week / 500 kms and this started at day 4 or so. I'm in QC (Canada). Exact hissing sound pointed out in a Google Drive video in an earlier post and described in first page or 2.
Will be sending it to dealership this week to see if they can figure out what's wrong but to be clear ; has anyone determined the actual cause for this and is Hyundai doing aware/anything about it?
