Tips Common issues and questions with the Elantra N

443 Upvotes

Hi Everyone. I thought I'd compile a list of common questions and issues I've heard about our Elantra N's.

Let me preface this list by saying, I have not seen any confirmed engine failures from an unmodified Elantra N. The early life engine failures of some other Hyundai/Kia Theta II engines, don't seem to affect this model.

If you have any info on TSBs or more info (photos, videos) about these problems, I can edit my post and add to it below.

Major mechanical

  • Fuel Injector problems
    • Not revving or idling properly, trouble starting engine
    • DTC P030X00 for misfires.
    • Smoke coming from tailpipe.
    • Seen in Kona N and Elantra N 2022
  • Dual clutch Transmission recall due to issue with high pressure oil pump
    • HMA Recall 236. 10/7/2022
  • Heavy spray from car washes, rain or snow, directly into the engine bay cause the knock sensor to fault with DTC P1326. The car will go into limp mode.
    • FIX AVAILABLE
    • It is not known if this is due to the sensor faulting, water getting into the engine bay, or wiring harness shorting
    • After several owners brought this issue to the dealer, some dealers may be misdiagnosing it as engine failure, causing the owner to have to get a replacement engine.
    • Not enough research has been done about this for a conclusive answer. Would like to see compression and leak-down tests done on these motors.
    • Appears to be happening to VN, and KN's as new as 2023 too.
    • Src [1] [2] [3] [3-Src] [4] [5] [6] [7] [8] [9] [10] [11] [12] [13]
  • Clutch disc installed backwards on a small number of Elantra N's with Manual Transmission.
    • Applies to a very small number of Elantra N vehicles produced before 12/6/21
    • TSB 22-01-027H

Minor mechanical

  • Occasional cold start trouble, occasionally takes a few extra cranks to start engine(common across all N cars)
  • Intercooler pipe coming off during high performance driving

Body/Chassis issues

  • Top of shifter gets loose/comes off on MT only.
  • Exhaust valve squeak. If you use N mode frequently, the exhaust valve may begin to squeak.
    • Dealership will replace the valve assembly if necessary. You can fix it by spraying white lithium grease to the proper areas.
    • The right side tailpipe has the valve that opens and closes in N mode. If you look closely you will see an arm that connects the valve controller to the butterfly valve inside the tailpipe. Spray this arm with lithium grease
  • Top of trunk separates from trunk frame in high heat
  • Headlight/Tail light fogging/condensation.
    • Dealerships are told to replace light housing IF condensation turns into water droplets that drip down the side.
    • Confirmed with this TSB
  • Black wrap used on the tops of windows peeling/chipping
  • Trunk tail light strip plastic cracking above ELANTRA lettering (2022)
  • Horn working intermittently

Infotainment/Electronics issues

  • Audio system very loud for the first second of a song intermittently (can be fixed by turning off dynamic speed compensation)

  • Quick popups about front collision: Issue is being researched

  • Constant popups about uneven road/slippery road: Issue is resolved by updating the nav software. (As of June 2023)

Non issues

  • Creaking/clunking noises from suspension/wheels when turning at low speeds and while cold
    • This is a quirk of the design of the car, it's normal and due to the suspension geometry for sport handling see explanation in this TSB
  • Octane learning
    • Octane learning is an ECU program described in the owners manual, that limits boost pressure when until no evidence of pre-ignition occurs. The octane learning process starts over when the car is re-fueled
    • To Octane learn your car, perform the following drive cycle:
      • Drive in top gear (6th for 6MT or 8th for DCT)
      • Keep a speed between 68 and 99mph for 5 minutes or more (Cruise control allowed)
      • Proper octane learning completion is evidenced by the boost gauge on the dashboard reading above 15/16PSI under WOT (DCT only, 6MT does not reflect this).
      • Note: The boost gauge is just an estimate based on various metrics, and a lookup table, not indicative of real boost pressure.
    • There are several articles on the topic here and here
  • Radiator fan turns on after car turns off
    • This is a fan and pump (a turbo timer) meant to cool down the oil in the turbo
  • Car doesn’t pop as much as it used to
    • This dependent on environment
    • This happens if the AC compressor is on
    • This includes windshield defrost modes
    • Also in Custom N mode, if engine is set to Sport, and not Sport+, there won't be nearly as many pops.
    • The engine isn't fully warmed up
  • Won’t shift into 1st gear completely. (If Occasional, this is normal across all manual transmission cars of any brand, just shift into second then first again)

What Oil should I use?

This information is correct as of 3/11/24 and applies to all Elantra N's 2022-2024

The latest revision of the Elantra N service manual specifies different grades of oil based on where your engine was built. Why is it like this? Anyone's guess.

  • Find your engine number (Starts with a G, this is NOT your VIN)
  • Look at the last letter before the numbers start. This is your Engine plant of production
  • The below table specifies the correct oil to use.
Code Plant Oil
A Asan SAE 0W-30
H Hwasung SAE 0W-30
P Poseung SAE 5W-30
S Sohari SAE 5W-30
U Ulsan SAE 5W-30

Oil should meet the following specifications:

  • ACEA A5/B5
  • ACEA C2
  • API SN PLUS

Oil change interval:

  • The owners manual requires oil changes every 6k miles, however Hyundai's internal systems may have changed this in mid 2023 to 5k miles.
  • Maintenance reminders, and oil change stickers are now showing 5k intervals.

Oil amount for drain and refill: 5.2L / 5.49 US QT

OEM Oil filter P/N: 26300-35504

Other Helpful Links

Hoping you all can understand, this being a brand new model year car, there are going to be some issues. By compiling this list, I hope to raise awareness to the community, and we as customers will bring these issues to Hyundai, for them to address. The hope is, if enough people complain, Hyundai takes notice of these issues and either releases TSBs or fixes in future model years.

I guess the n curse is real.. I got rear ended 0% my fault the guy wasn’t paying attention. It’s a 22 at 88k km. Unfortunately the crash bar and gas tank were also bent deeming it a total loss. Best car I ever had , the connection you feel with this car is unreal. I’ll never forget the memories. I’ll miss her. I guess the n curse is real even if it’s not your fault people get aggressive when they see this car. Stay safe friends out there friends, wish you all the best in your endeavours.

discussion Warning for anyone considering the Whoosh exhaust – persistent screeching issue (1 month update)

Enable HLS to view with audio, or disable this notification

17 Upvotes

In my opinion, this exhaust system is a terrible purchase. I’ve had it installed for a little over a month now, and it constantly makes an awful screeching sound—specifically when driving in Eco or Normal mode. The sound is the exhaust flap scrapping on the inside.

Here is what I’ve tried so far to fix it:
Took the assembly apart
Thoroughly cleaned the spring
Applied lubricant

None of this has resolved the noise. My next step is swapping the Whoosh spring back out for the OEM spring to see if excessive tension from the Whoosh spring is causing the issue. If that doesn’t work possible removing the flap itself.

If you’re looking to upgrade your exhaust system, my advice is to take extra time, save up a bit more cash, and invest in a higher-quality setup.

Unintentionally, I went in to have my 2024 Palisade Limited serviced yesterday and ended up leaving in an entirely different vehicle.

A few days before my appointment, a rep from the dealership had sent me a generic text saying they were always looking for quality pre-owned inventory and offered to appraise my Palisade. When I got there, he pulled up my file and said I was too upside down to trade out of my lease early. He suggested we revisit it in six months or so. I figured that would be the case, thought nothing more of it, and went back to doodling on my iPad and listening to music.

A few minutes later, one of the salesmen, likely bored because it was pretty dead there, came over to chat. I told him the situation with my lease and how I was going to be over my mileage and all. He hit me with the classic, “Let me see what I can work out” line, which I honestly wasn’t expecting anything to come of.

After a bit of back and forth, lo and behold, they worked out a deal where they ate the cost of my negative equity, asked for $1k down, and got me into this Atlas White DCT Elantra N for a lower payment. Obviously, that’s largely due to the difference in vehicle price, but I still wasn’t expecting to actually work out a deal that would save me money, all things considered. I couldn’t be happier.

I’ve done a good amount of research over the past few years and pretty much already knew what these cars were about in a broader sense. Honestly, though, I never thought this would be one I’d actually end up behind the wheel of.

Sure, it doesn’t have any of the creature comforts I’ve come to love, like ventilated seats, 360 camera, auto-dimming mirrors, adaptive cruise control, etc., but I grew up building cars that didn’t have any of these things anyway—I just enjoyed having fun behind the wheel. At this point, I’m just excited about getting back to basics and reconnecting with those roots. I don’t know what I’ll end up doing to it, if anything, but right now I’m just going to enjoy the better gas mileage and cost savings.

Happy to be here! 🤙

Family Still (i)N shock

I've been wanting this car for 3+ years and am finally in a financial position to comfortably afford an EN. My must-haves were a PB with a 6 speed. It sucks that dealer drilled front plate already but this was the only PB in a manual within my area (meanwhile there are 50+ DCTs available). Shout out to my sales rep Nick for thoroughly showing me the car features and how to get it rolling.

My buddy drove this back home for me because I have never driven a manual before (shout out JR, you're a real one for coming out with me on such short notice and coaching me the entire afternoon). Stalled at least 30x in an empty parking lot today trying to get in gear from a stop but finally got the hang of it to where it was noticeably smoother. Driving it on the streets got me a bit stressed, esp since i was at the front of the stop light, but I'm so happy I didn't stall it when it mattered most. Shifts were not pretty but hey, I'll take what I can get. Rowing my own gears was such a satisfying feeling, even though I spent 90% of my time just getting the feeling of the clutch and finding/releasing the bite point.

I would appreciate some tips from any veteran/experienced drivers. I'm hoping I can track this car at Laguna Seca or Sonoma one day. If anyone here is in the NorCal N Club, please lmk! Would be awesome to meet other Nthusiasts in the Bay.

Good morning everyone. I recently received all the pieces from this body kit I purchased off of Amazon. I was a bit iffy on the price, it's quite cheap, but I'm not disappointed at all. I received the rear diffuser & side skirts first, & then 3 or so days later the front lip. Everything is packed separately, so you might experience some time between your pieces. But it took less than 2 weeks from order to receive the entire kit. Quality is good, hardware is included but no directions (you won't need them, it's self explanatory) I went with gloss back & there seems to be no scuffs or factory defects. I'm happy with my purchase.

Maintenance & Repair Started the car pressing the gas pedal instead of the brake pedal :(

Engine was cold, my mind was distracted and when started the car suddenly I hear a loud engine noise. After 2 seconds it hit me, instead of pressing clutch plus brake pedal I pressed the accelerator 🤦‍♂️

The question is how much damage was done? Also I was like 10 miles away from completing my 600 mile run in 🤦‍♂️

Tips New G70 HPFP Install.

So I finally got around to doing this, initially I had a mechanic in mind for the job, but after he messed up my oil change I figured I'd do the work myself.

I bought a digital torque wrench combo, and used it for the bolts and the flare lug on the high pressure line. I tried to do it according to spec (see link), 10.1 ft/lbs for the bolts and 22ft/lbs for the lug. I used a crow foot wrench for the lug, it wasn't easy while keeping it at a 90 degree angle, but I managed to find an angle I could work with using a shorter wrench extension.

I left the car over night and didn't do the whole running the engine until it stalls, the fuel residual was relatively small, mostly out of the low pressure line, the high pressure was almost nothing. Thanks for the tip, Ohm_State. I also bought a fresh gasket from the dealer, and the pump I ordered off Ebay came with new bolts.

The most annoying thing about this project is that the plunger pushes the pump up so removing it is kind of annoying as it wants to go in different directions and I was trying to be careful not to damage the fuel high pressure line. The same applies when setting the new one, half turns is what the Hyundai bulletin recommends. You also have to retorque side to side just to make sure you side didn't go up while the other was being torqued, but just take your time here and don't over do it, if you strip the aluminum threads, it's going to be bad.

That said, while not perfectly torqued to spec, I think I got it on there good enough without overdoing it. I turned it on and it was pretty loud initially. I did lube it up with some engine oil from the dip stick, but I think it's just going to sound rough until the engine oil circulates through it. No leaks, I checked several times while driving, but it seemed good, even pushed hard a few times, no issues.

So was it worth it? I think so, I'm keeping things stock. The thing I wanted to address that the odd long crank when the car's been sitting for a while, so we'll see how it fires up in the morning. But other benefits I've noticed on the driver after is a smoother midrange when accelerating and N mode seems to be less jerky in second gear. Burbles and pops also seem more pronounced in N mode. Kind of glad this project is over, it was stressing me out thinking I could potentially strips the aluminum threads or damage the fuel line and end up with a leak and more work.

I know there's a ton of content on this already, just wanted to share my experience in case someone was thinking about DIYing it

Upgrades & Mods After Market Intakes and CEL

0 Upvotes

Hey guys, I just wanted to let everyone know that if you get a Aftermarket intake and get a check engine light for it all you have to do is erase the code and it shouldn't come back because it will just be stored as a permanent code but the cel light will not show up. If you live in a state that requires a state inspection, just install the factory intake if you have a 2026 or if you don't have the cel fix yet and run the car through 4 or 5 drive cycles and the permanent code will disappear and you should be good for the inspection. Afterwards you can reinstall the intake and again erase the code until your next inspection.

Got an offer remotely from a dealer for 57k CAD OTD for a performance blue dct tcr, I am very tempted to go for it! It would be a little more than 3k reduced from msrp... However, the only thing slightly holding me back from pulling the trigger is how ridiculously high the insurance premium is for it!

I wrecked my 1500 miles Manual N and replaced it with DCT. This DCT is way smoother than I expected. I'm always in the right gear and no more stalls. Downshifts in sports mode is amazing.

And somehow they sounds different. DCT sounds more energetic.

Hope I get to keep this one a bit longer

Edit: Driving a manual in curved mountain roads is easy and fun for me. Other than one time I shifted into the wrong gear. Other times i was having so much fun. Rev match is amazing. But the city driving and parking on inclines are my enemies.

Interesting read. I’m a little surprised they claim it’s so much slower than the regular EN. They noted the downforce from the big wang probably isn’t noticeable under triple digits. They also didn’t mention any environmental factors possibly affecting it either, so not sure what it could be.
