Hyundai Kona road Noise

Post by davidEV »

Hi All,
Took delivery of my Hyundai Kona in July 2019 in Brisbane and immediately returned home to Toowoomba up the mountain. Very enjoyable journey. I did note that excessive road noise was coming up from the back seat area. Within a week I sourced 2 rolls of Jaycar AX-3687 sound deadening and put it all around on the metal in the boot area and over the metal area just behind the back seat. I was careful to leave the plastic shield over the sticky mastic near any wiring, so the sound deadening did not stick to it, if the wiring has to be accessed at any time.
I was absolutely thrilled with the difference that this made to the inside quietness and would recommend this if you are chasing road noise inside. The Kona has travelled nearly eleven thousand Kilometres so far of very enjoyable driving.
Regards David

I used that exact stuff on the converted Prelude to dampen the racket of the A/C compressor. Makes a big difference.
Glad you're enjoying the Kona :) I grew up in Warwick, so the only time we took the Toowoomba range road was when the Gap was closed.

Photos please!
I'd like to do this, but I'm unsure exactly where/how you applied the stuff.

The sound deadener has a sticky back when the covering is peeled off. That is why I left the covering on over any wiring. I have attached a photo showing the boot well with slots left for the insert to fit in without the deadener interfering with the insert fit. This is the first time I have tried to post a photo. If it does not work I need some advice

Used the same stuff on the Prelude engine bay:

I had a lot more junk to work around, but it worked.

Thanks David.
My Kona is due late March. If they haven't improved the acoustics, this will be a great way to fix it.

Cheers,
Phil

Is that as good or better than this stuff and what about price? http://www.dynamat.com/automotive-and-t ... at-xtreme/ This is the stuff they swear by for sound deadening a VW Kombi, you know all about road noise when you own an early model one of these :lol:

It's just off brand dynamat, like black and gold cornflakes vs kellogs. There's a difference but lots of people are happy with the cheaper stuff

Is the Jaycar stuff cheaper? I'm guessing from reading a few of the posts that they were the supplier

Thanks for the tip David.

I just did this too. Two rolls of the Jaycar AX3687 product ($32.95/roll) was just right to do the luggage area. The foam bits all still fitted back in. I am reasonably sure it has made a worthwhile noise reduction but my wife says she can't notice a difference.
