Silencing the Annoying TRIM RATTLE in my 2017 Hyundai Ioniq Electric using minimal tools

I find and fix the incredibly annoying trim rattles in my 2017 Hyundai Ioniq electric.

My boot spoiler was rattling and when I removed the wide centre plastic piece, I found that all three nuts were unattached, so I have now screwed all three back in! Thanks for the video, otherwise I would never have attempted it myself!

I've got the very same problem. Thanks for the video and suggestions

I bought a new 2021 Subaru Legacy (saloon version of the Outback in the US). It started having loud rattles and buzzing in multiple places just five months after I bought it. By the end of first year it had more interior rattles and buzzing plastic trim than the ten year old Mitsubishi Lancer I traded it in for. Biggest rattle trap I've ever owned. I took it in to the dealer trying to fix them five times. They only managed to quiet two of the half dozen. After 2 1/2 years I got rid of it for a Hyundai Tucson and so far it seems to be a much better assembled car.

I’m just like you and rattles drive me crazy! I have the hybrid version but I’m positive it has the exact same issue. Thanks for making this video and doing what work you can yourself goes a long way.

[@Endfloat]

Best of luck getting yours sorted.

Hey Ross, what I do to hunt rattles is use a tone generator app playing through the cars sound system. With a sine wave, slowly increase the tone from about 80hz until you find the resonant frequency of the rattling part. It'll go mental when you do. 😉

[@Endfloat]

That's so clever! And I actually have a tone generator!

[@df-uv8gy]

@@Endfloat Has served me well. Had an A4 with a really annoying cockpit rattle that I was sure was coming from inside the dash pod, so lived with it for too long. 10 seconds with the tone generator and found it was the switch for the visor mirror light.

Rattles drive me crazy but I always remember a saying from my Grandad to just turn up the Wireless 😂😂, great little tinkering video as always Ross.

[@amindyourbiz]

Thanks for the video. To future viewers, there’s no need to remove ANY of the plastic trim if you’re just trying to fix the spoiler only. You only need to remove the 4 rubber grommets on the right and left sides on the outside frame of the hatch. They can be accessed by simply opening the hatch. All four of nuts holding mine were almost completely backed off the bolt. I was definitely going to lose that whole spoiler very soon.

[@Endfloat]

Thanks! There are other bolts for that spoiler under the trim though. It's not just the 4 on either side of the hatch.

I think you saved me a world of frustration. I think I'll use blue loctite when I do mine.

Mine rattles and drives me mad. It’s my back seats. There is play the bit here the retractable seats locks against the latch. The dealer said give the metal hook a bang with a rubber mallet to bend it ever so slightly and that will make the latch lock in place tight with no play. Also, there is rubber screw able bumpers on each end of the boot where it would close against the bumper. Two rubber buffer stumps. They retract and screw out too. Adjust them

[@GamerGrit86]

Thanks for that. Fixed mine.

[@Endfloat]

Glad to hear it! 😎

[@nobilitylord]

Thank you you save my mental health 😅

[@glockieme]

I had a similar rattle from the back of my ioniq. Discovered it was from an umbrella under the boot liner! Good video man 👍

[@geo6307]

Thanks fot this vidéo. Also in my case all three nuts in the midle unscrewed.

[@Endfloat]

It's obviously a design flaw.

[@geo6307]

​@@Endfloat I also had a noise from the rear seat anchors. Maybe I cleaned too much. I put some grease and now it's completely silent.

[@jakemybigblackdog]

Would you not have used thread lock with the 10MM?

[@Endfloat]

No I like to live dangerously! Honestly, they shouldn't need it. They're well nipped up so we'll see. If I've to do it again I'll put thread lock on then.

[@pyronitro]

noises like that drive you mad because you constantly try to listen to the car. silence means a well maintained car. noise means a not so well maintained car and a problem that needs to be fixed. i have a prius that i thought the suspension bushings were going out. i was seeing expenses. but after many many inspections at the wrong places. it finally boiled down to loose brake pads in the calipers. a bend of the spring clips and it was fixed! but! after that there are now other noises because you just fixed the noisiest one that was masking it. it never ends.

[@Endfloat]

It being a modern car, I don't consider trim rattles to be acceptable. I don't accept it in my classic cars!

[@nero19]

Did it fix the problem. I’m at my wits end with my Ioniq. Serious noise from the back

[@Endfloat]

No actually. It got rid of one of the rattles but not the other. I'm thinking it's the wheel arch liner actually.

[@nero19]

I was thinking the same as the liner is loose to the touch on front side.

[@nero19]

Just figured mine out. The rear seats where they latch was rattling. I put insulation tape on the metal connector. Rattle gone TG

[@ArickEng]

I think I've narrowed mine down to the plastic tube over the rear shock absorbers. I tore my rear trim apart and couldn't find the source. Mine sounds like a glass pane rattling between two plastic bits, a vibration of sorts when going over uneven road.

[@brianmac8260]

Not something they could find on the computer, yep you'd get it back the same.

[@smashyrashy]

Absolutely riddled with plastic! More plastic than metal in cars now but no wonder it's noisy😂
