ELECTRICAL SYSTEM
Battery Management System light came on 1/22 , battery wouldn’t charge past 80% - took into Kia Burlington NJ for service- they diagnosed vehicle and put it on charger and was told issue was resolved. I am noticing that my battery pack is having issues- battery pack is 99kw when it goes down to 10 % in can charge it all the way to 100% but only 50kw is dispensed. Meaning that there is 40kw of battery that is unaccounted for. My max range is extremely limited to 120mi on a full charge. I understand winter can affect range but with the constant charging- i haven’t been able to dispense the full 90ish kw of charge. Concerned about my safety and a potentially defective battery pack.

SUSPENSION, STEERING
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.

SUSPENSION
The Kia EV9 has a defect in its suspension that causes the rear end to "bump-steer" over imperfections in the road, giving the driver a scary sensation of losing control. For example, driving on the highway in a corner, if you hit an expansion joint or pothole, the vehicle will require a quick steering correction while the vehicle's rear-end enters what feels like an oversteer condition. This reduces confidence in the vehicle's ability to hold the road. In poor weather like snow, it's impossible to discern whether the vehicle's rear end is sliding, or if it's the bump-steer condition occurring. My wife refuses to drive the car in inclement weather, despite the vehicle being fitted with snow tires. It is a very scary feeling. Kia has yet to issue a TSB for this on 2024 and 2025 model year vehicles, and it seems that all trim levels are affected after discussing with the community on forums. Even after dialing in the alignment perfectly to manufacturer specifications, the issue does not resolve.

SUSPENSION
We've had the vehicle for about six months as my wife's primary car. within the first week of driving the vehicle, she noticed it "hops around" when encountering irregularities in the road surface at highway speeds. After driving it myself, I agree—the vehicle gets unsettled while driving over seams, bumps, or uneven surfaces, even minor ones like raised seams or potholes. This happens and is most noticebale at highway speeds, both while driving straight and through corners, with the rear end feeling like it's skipping, hopping, or "porpoising." Even with small irregulairities in the road the vehicle lightly sways. Tire pressure is set to manufacturer specifications, and there's no noticeable irregular or excessive wear on the tires. When I have spoken to the dealership about this, they cliam that it's perfectly normal becuase it's a heavy vehicle (referencing a 3/4 ton pickup). This does not inspire confidence in dirving the vehicle and is likely to cause an accident.

SUSPENSION
At highway speeds, the SUV experiences significant body sway when hitting a bump, causing it to rock side to side in an unsettling manner. This issue makes the vehicle feel unstable and nervous, requiring the driver to slow down to regain control. The excessive body roll presents a potential safety hazard, as it could lead to a loss of control in certain conditions. Based on my research, this problem appears to affect the GT-Line model more than others. A solution is urgently needed to address this serious handling issue, but so far, Kia Corporation has done nothing to resolve it.

WHEELS
While driving on the freeway I suddenly lost control of the vehicle, with the vehicle swerving left and back across several lanes. Thankfully, I avoided a catastrophic accident and managed to pull over safely. There were no warning lamps or messages of any kind prior to the failure. Upon inspection of the driver’s side rear wheel, I discovered that multiple lug nuts had snapped off, with the studs still attached to the lug nuts. The remaining lug nuts were extremely loose. I have never heard of such a dangerous defect in a brand-new vehicle, and it appears as if the wheel may not have been tightened properly before I took possession or they loosened since then (possibly due to having had just driven through freezing temperatures). I had only had the brand new car for 5 weeks and added 400 miles to the odometer (total mileage 544). Inspection report was provided by the nearest Kia dealership “Found 2 lugs snapped off taking the stud with it, and the rest of the lugs were loose. Damaged rotor screws, lug studs, and the wheel. Recommend replacing the hub assembly, lug nuts, wheel, and recheck vehicle operation.” Kiais claiming this is not covered by Warranty and is so far refusing to make repairs.

VISIBILITY/WIPER
We had a snow the last couple of days and when it mostly cleared up we went out to the grocery store. We had done on best to clear of the car of snow. While driving the windshield wipers were working fine until a small chuck of snow came down from the roof of the car. The wipers immediate started to glitch and not move which caused a big visibility problem. I was able to pull over and clear it but was concerned that small amounts of snow would cause the wipers to completely stop.

STEERING, SUSPENSION
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.

SERVICE BRAKES
Vehicle was stored in a closed garage prior to operation. I started the vehicle and began to back out of the garage into the driveway. After approximately 3-5 feet of movement backward, several yellow warning icons illuminated on the dashboard and the vehicle's brakes stopped functioning. The vehicle free-rolled several feet down the driveway. After about 1 second, the vehicle brakes engaged, all warning lights went out, and the vehicle began operating normally. I attempted to replicate the fault but was not able to. I feel this is a safety concern because uncontrolled rolling of a 2-ton vehicle could cause a crash or I could have rolled over a small child or a dog on my sidewalk! Ambient temperature 56F with no precipitation and low relative humidity. Garage was at roughly 65F. Vehicle has 3,960 miles on the odometer and was at approximately 40% charge on the main battery. I am currently on hold with Kia to report the issue (20 minutes and counting).

ELECTRICAL SYSTEM, SERVICE BRAKES, STRUCTURE:BODY
The 12-volt battery for the vehicle was depleted, so the vehicle had to be jump-started to run. I work for a repair facility (it was here for collision repairs, as far as I know unrelated to this issue) and since I was unfamiliar with the vehicle, I inadvertently turned it off before shifting into park. When I took my foot off the brake, the vehicle began to roll forward. I am not sure if the vehicle was in park, neutral, or even reverse (the gear I was in when I turned the vehicle off), but whatever gear it was, the vehicle kept rolling after it was turned off. I tried turning the vehicle back on to shift to park, but was unable to do so due to the depleted 12-volt battery. I tried hitting the park button anyway, and this did nothing. I then tried to engage the electronic parking brake, but this was also inoperative due to the lack of power. With each attempt, I tried briefly taking my foot off the brake, but each time it continued to roll forward. I then called my manager and asked him to jump start the vehicle so I could put it in park and engage the parking brake. No damage was done in this incident, nor was anyone hurt, but this lack of fail-safes to prevent the vehicle from moving after a loss of power is a significant design flaw and safety hazard. If I had not noticed the issue in time and gotten out, the vehicle could have rolled away and caused property damage or bodily injury to me or a bystander. To my knowledge, this is the only such incident with this vehicle, and I do not know whether it is specific to this particular vehicle or replicable in others of the same year make and model. There were no warning lights.

POWER TRAIN, SERVICE BRAKES
There is an "i-pedal" feature that sets regen braking to bring the vehicle to a complete stop when letting off the accelerator pedal. In this mode, the vehicle only moves when pressing down on the pedal, and it stops when the pedal is released. When shifting the vehicle into reverse, "i-pedal" is automatically and silently turned off, causing the vehicle to suddenly start moving when releasing the brake pedal and no longer stop when releasing the accelerator pedal. This is dangerous because the pedals suddenly and unexpectedly behave differently with no input from the driver. If "i-pedal" is enabled by the driver, it should not switch out of "i-pedal" without the driver choosing to do so.

STEERING, SERVICE BRAKES, UNKNOWN OR OTHER
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.
