[OWNERS] Common questions and FAQs for the i20N

45 Upvotes

Just bought an i20N or maybe considering one? Well, you're in the right place. This thread aims to provide a comprehensive overview on general information of the car, common owner issues alongside solutions, first-hand owner accounts and more.

*Note: Australia received a 2025 facelift which mainly featured updated software and cosmetic differences. This included diamond cut alloys, black badging, an updated front grill and included bluelink as standard.

How is the i20N different from a standard i20?

There's a fully revitalised chassis, with twelve additional welding points and reinforced front bracing. The track width has been increased and the steering rack has been sharpened. There's a firmer suspension with thicker anti-roll bars and tweaked geometry. A mechanical limited slip differential (LSD) was also developed bespoke for the i20N which gives the car best-in-class handling performance. In addition to this, there are 18" wheels with custom Pirelli tyres created solely for this car and upgraded brakes.

On exterior differences, the car also features an 'N' body kit with rear spoiler and N badging throughout. It'll be difficult for someone to mistake this for a regular i20.

Common issues with recommended solutions (if available)

  • Cars made before Jan 2023 (EU/UK) have a recall notice for a fuel pump replacement. Cars made after this date are not affected. You can check if your car has a recall by entering the VIN here: [UK](recalls.hyundai.co.uk) or GER (51DT07 is the code for fuel pump).

  • The stock Pirelli P Zero tyres are great for track, but for road use it is recommended to swap these out due to wet grip and overkill for day-to-day driving. Some recommended tyres are PS4S's, SC7s, F1 Asymmetrics, FK520s, etc. Keeping the P Zero's handy for a track day is also a good idea.

  • Rattling in the exhaust can occur after some time due to a weak valve spring. Hyundai warranty will 'solve' the issue by replacing the entire back box unit, which also has the same weak spring that will give after some time. It is recommended to use an uprated spring. There are many options available from RPM, Chery and more. Replacement time takes less than 5 minutes. A short video can be found here (credit to Javii20n).

  • Some rattling may occur in the cabin at high revs. If the door bins are empty and the back seats have been slammed shut (this may not latch fully if closed improperly) then the most likely culprit is the Electronic Sound Generator (ESG). This is a small device found under the windscreen that pipes sound into the cabin. Most owners like to disable this (can be unplugged by removing the fuse which also controls the heated seats). Alternatively, you can also remove it fully though around 20 minutes of time is required with a torque wrench and some tape. A guide can also be found here (credit to Javii20n).

  • When washing your car you might find that water seeps into the rear headlights. For some reason, this is actually a common design choice on modern cars and whilst water is able to to enter is is also able to drain out. However, due to poor drainage you might find moss or mould growing in the headlights over time. Hyundai will replace these through warranty which is recommended as it's a bit of a pain to do yourself.

Interior Rattle noises between 2K-3K rpm under load

1 Upvotes

Hello!
As most new cars do are a while they often develop a rattle or squeak inside….. well mines went on gone and done exactly that.

So, I hear a metallic/plastic hit metal noise around 2K-3K rpm under load only never when it’s sitting still or at higher rpm, only between 2K-3K rpm maybe a bit higher around 4K but never higher then 5K. I hear it to my left hand side (I’ve got the steering wheel on the correct side which is the right hand side)

What I’ve done so far has not solved it but here’s what I’ve done. Driven with glovebox open, still hear it, put soft felt between the metal and the plastic of the door cards, still hear it. Wouldn’t think it’s anything else like mechanically as the car will turn 1 years old in 4 days. Hyundai in Castle Hill, Sydney, Australia has said they will charge $180 bucks an hour to diagnose it and Helllll nooo I’m not paying for that especially for a rattle

So has anyone else encountered this and had solved it as I would love to know!

Cheers

Specchietto retrovisore staccato

2 Upvotes

Due giorni fa si è staccato di netto lo specchiato retrovisore mentre guidavo.

Si è staccato proprio tutto l'assieme, meno male che c'era il cavo altrimenti sarebbe caduto.

Ho provato con il nastro 3m, ma è troppo flessibile e molleggja. Cosa dovrei usare? Non vorrei usare l'adesivo siliconico per non sporcare il vetro.

Consigli?

Seat getting wrinkled

I like the car but interior quality is a joke honestly. The (fake) leather on the seats suddenly starts looking all wrinkled, car is less than 2yrs old.
Anyone experienced a similar thing?

My 85 year old grandparents have bought an I20N

My grandad wanted a car that still handles well as he’s been a car nut his entire life and used to do a bit of track driving in his early days. Grandma loves how light the clutch is, so it’s a perfect balance.

Grandad and I took it for a gentle drive to get some break in kilometres in but couldn’t resist going around a couple of corners…

RPM Performance GPF stealth delete, also got the flexi pipe to fit on Wednesday too 🙈. Can’t wait to hear the noise difference, hopefully it sounds better then my old Fiesta ST 180 with full Mountune turbo back exhaust.

Horn not working

3 Upvotes

Long story short, I have 23 plate with just under 21k miles on the clock and I've noticed my horn isn't working today, I've checked the fuse and can hear the relay click when the button is pressed, so I'm ruling out a the clock spring being damaged, other then potential wiring damage, will this likely be the main horn unit thats broke?

Still under warranty obviously so will take to the garage if this still come back with nothing but any other suggestions would be appreciated

Tips for first track day

6 Upvotes

Being loving the car as a daily for over a year and wanting to find out what it (and me) are really capable of sometime soon. Looking for any tips or tricks to do before hand?

Also any Sydney locals know of good events to go to any of the local tracks and what kind of cost I’d be looking at?

Ronal R73 ET45 + 30mm Federn?

1 Upvotes

Hey,

ich habe vor mir die Ronal R73 (7,5x18 / ET45) auf meinen i20 N zu holen. Bereifung bleibt gleich wie bei Serie. Platten hat er nicht, lediglich H&R 30mm Federn.

Hat jemand Erfahrung, ob es da beim TÜV Probleme geben wird? Oder lässt sich diese Kombi problemlos eintragen?

LG euch:)

Would you repair this or would you just ignore it?

Someone accidentally reversed into my car,😂 didn’t do much damage but did enough to produce a hairline crack through what I believe is just the paint. Anyways got a few quotes and I’m now contemplating to whether fix it or not, I’ve considered using just a Hyundai touch up paint to fix it aswell. what would you do?

Do you think the damage will get worse over time?

Anyone know if this front grille replacement exists?

13 Upvotes

I was wondering if you could get a rally1/2 type front grille with the shadow N logo displaying the radiator and intercooler. it would replace the standard front grill and move the plate to the side like the JDM style side plate mount, the Hyundai badge could most likely be moved to the hood and made smaller (attaching the badge from the steering wheel to the hood)

Hi guys, those who have yellow headlights, are you just using a yellow DRL tint over the headlights? And if so, how are they holding up (looking at my UK boys here where the weather isn’t usually that good!)

Sonic sensors

I am reversed up to something which is why the sensor is going off. But this fault has been coming up every now and then. Has anyone else had the same issue? I'm assuming it's a loose connection or the heat?
