EV9 owners check this NOW!

Thanks for the video. Yes, we got an alignment of our EV9 GT-Line about 2 weeks ago. Ours was absolutely horrible over big joints on freeways and would sway like crazy. The alignment fixed it perfectly. Tire pressure didn't make a difference for me unfortunately so it cost $99 for an alignment.

I just finished my first road trip from Houston to San Antonio and back. I experienced this issue and thought it was cross wind as I noticed the trees moving. I will check my tires to verify over/under inflation. I will report back in August after the completion of a trip to Dallas, TX.

Hiii I had this issue on my GT-Line. The PSI was always set to 38. Many models have incorrect alignment calibration from the factory (allegedly) where the rear wheels aren’t perpendicular to the ground (they’re slightly angled inward). Fixing that helped a ton, but then they messed up the alignment in a different way and made my car pull to the right. I just had THAT fixed, and now the rear sway seems to be back…just not as bad as before 😂 Early adopter problems bb. You can get an alignment for free now / don’t need to wait for your first service. Keep us posted.

I noticed this issue with a Ev9 GT-line, especially noticeable when full drive assist is on.

[@molohov3875]

Wow. The tire pressure on my two week old EV9 are all between 49-51 PSI. And this was driven off the dealership lot. Sounds like they're not following spec

[@mattscinto]

Yeah I think mine were that high when I got it. I’m curious to see if any different now.

[@molohov3875]

Any updates after deflating?

[@uutube243]

2024 EV9 Land don’t have sway problem however had the very common problem of the foam coming lose in tires causing vibrations at speeds 62mph to 75mph

[@LeighHart]

I believe the reason why is they are shipping them at high PSI and dealers are supposed to be deflating them back to 38 before delivery. My land AWD was delivered with 38 all around.

Yes I have this issue and I have GT-Line - many have the problem. I had a Land loaner and it does not have this issue so could be the self leveling rear suspension. I have yet to pick up mine bc dealership got into an accident with my car while working on this very problem. So far their fix is alignment and adjustment of the suspension as it was out of whack to the designated settings.

[@560val]

Get an alignment and it should fix the issue. FIxed it on our GT-L.

[@monroe177]

I have this problem with my GT-Line, and I've already confirmed the tire pressure is correct. I brought it to the Kia dealer to check it out and they said there's nothing wrong. Since they couldn't claim it as warranty, they charged me for the diagnostics. Thanks Kia.

[@mattscinto]

Yikes I’m sorry man.

[@vankode]

That is normal on all long wheelbase vehicles - same in my EV9, Ioniq 5 and Mercedes Benz S class long base. And yes - the higher the tyre pressure - the more you can feel it.

[@tourer65]

I ve a 2023 ev 9 gt line and never felt such a problem using 41 psi tire pressure

[@vankode]

You should try at a higher speed on a bumpy road at a turn.

FWIW I have a Wind with rear springs and I have not noticed this issue.
