2024 Kia EV9

When driving at speeds 60+ mph, EV9 steering wheel and center console vibrate consistently even on newly paved smooth road(s). I have taken it into two different dealerships for resolve twice within the first week of ownership. Both dealerships checked tires, mount and balanced the ones that were off and sent us on our way. The steering wheel and console vibrations persist. I have taken it back in and reported that the issue hasn’t been resolved. They noted it on the service order but did nothing further in an effort to resolve the issue. This is a well known and documented safety issue on NHTSA complaints and several Facebook owner groups for the EV9 across the world.

Vehicle experiences steering vibration when at highway speeds (above 65mph). I have brought the vehicle in for service four times and the issue still returned after multiple alignments, rotations, and road force balances. The local service techs are working with Kia, but it has currently been in the shop for 24 days with no resolution. According to the service advisor, tires have been inspected and even swapped with new ones but the problem is still present. I am concerned with the safety of the vehicle because it creates issues with control at high speeds which could result in an accident. Even at low speeds, the rear end fishtails over small bumps creating a temporary loss of control. I am unsure if the two are related. I can provide Kia service order numbers and Kia customer care case number upon request. Multiple other owners have experienced the same concerns and have posted a growing number of instances where the vehicle was purchased back by Kia as a result.

I have persistent vibration issues with Kia ev9. It is very much a risk as it causes concentration issues while driving. My tires are worn out at less than 10k. Looking at the forum and reports a lot of folks who have EV9 are facing the same issue. Is there a investigation which can be looked into as this can be a safety issue due to vibration as well tired being worn as well.

When you're at speeds greater than 15mph and hit a bump or encounter a surface irregularity (pothole, expansion joint, etc.), the Kia EV9 GT Line goes into a porpoising sway, causing the entire chassis to become unsettled. The swaying is much more pronounced when only one side of the encounters the irregularity, or if the car is not perfectly perpendicular to the irregularity and the left and right wheels pass over the irregularity at different times. The effect is especially noticeable in the rear. This unsettling 'swaying' increases with speed and happens both while driving straight and through corners. The rear end feels as though it's hopping or skipping from side to side. Out of all the vehicles I’ve driven—and I’ve driven quite a few—I’ve never experienced anything like this. During wet and slippery conditions, driving over small bumps or manhole covers has even caused the vehicle to lose traction and begin spinning - even while traveling at 25mph in a straight line. I purchased the EV9 in early 2024 and it has had the issue since delivery. I have heard many other EV9 GT Line owners complain of similar suspension issues and I am frankly surprised that there has not been a string of crashes and fatalities linked to the issue. I have spoken to the Kia dealership several times but because the vehicle is new they claim that they have not heard any other reports and they do not have the experience to diagnose or fix the issue.

When driving over uneven surfaces, like typical urban and suburban roads and highways, the rear end seems so wobble and slide. It feels like the heavy EV is about to break traction and slide sideways. It porpoises as well. It makes every passengers heart skip a beat. These are on dry roads, obeying speed limits, with the stock tires. An expansion joint, seam of two types of road material, utility cover or other irregularities can cause this. Easily reproduced but dealers or Kia America don’t seem to believe or care.

The manufacturer failed to align the vehicle at all prior to leaving the factory. The failed parts all have to do with the alignment. My safety was put at risk because of the persistent pull while driving, shaking while driving, instability at high speeds, and the fact that the tires are now damaged due to the alignment issues. The dealer kept the vehicle for over 60 days, and was able to rectify part of the alignment issues, but there are still areas that they are unable or unwilling to fix, as shown to them by the alignment machine. The vehicle has been inspect by a certified Kia dealership, as it was there for over 60 days. The issues were the shaking of the vehicle, the pull, the instability at high speeds, and the damage caused to the tires. It appear upon first taking the car home after purchase. I was forced to pick up my vehicle because Kia was unwilling to fix the vehicle, and they threatened me with storage fees.

I brought the vehicle in to have recalls addressed on 12/30/24. Starting the next day we noticed the car was weaving without any steering, but thought it might have been icy road conditions and waited to see if it reoccured. The car has since weaved intermittently, but has righted itself after releasing the accelerator. However, on 1/15/25 while traveling about 50mph, the car started weaving on its own and when the accelerator was released the car started to wildly fishtail. Called dealer and they agreed this was a serious issue and agreed to see car the next morning. Service tech said when they drove the car it did the same thing and that the troubleshooting recommended I change the regenerative braking setting to "smooth" and sent me on my way. I did not get even a mile before the car began weaving rapidly again on its own. Went straight back to dealership where manager wanted me to drive the vehicle again with the tech in car which I refused as it is not safe to drive. So he said if I was ok with it tech would take car out again but if it was just acting how regenerative brakes work, there wasn't much else they could do. When manager returned to talk to me, he said he ended up going with the tech and it did replicate the weaving action two times during that drive. The car is steering on its own weaving wildly left and right and imposes a great danger and no longer feels like a safe vehicle to drive.

Active lane keeping function feature disengages without audible warning leading to multiple near collisions. Happens without warning or any particular trigger. Was brought to the kia specialist attention and he did not seem surprised or concerned. Happens almost every time this feature is utilized at some random point in the drive.

Brand New EV9 Land AWD has wheel shake and vibration at 65MPH+. Center console vibrates and shakes substantially. Performed multiple wheel balances without and real change. Multiple other people reporting same issues. Not sure if this is tire, wheel, or driveshaft related. Kia America seems to not be interested in investigating this. This car drives rougher than a heavy class diesel truck.
