2025 Kia EV9 Problems

Vehicle Information: 2025 Kia EV9 GT-Line AWD VIN: [XXX] Mileage: ~16,000 miles Component/Part Affected: Wheel studs / Wheel attachment system Summary: Multiple wheel studs (3 on one wheel, 2 on another) were found stripped/damaged on my [XXX] Kia EV9, making the vehicle unsafe to drive. This is a critical safety issue, as wheels cannot be properly secured and could detach while driving. Details: •The vehicle has been serviced exclusively at Kia dealerships (Winn Kia Fremont and Putnam Kia Burlingame, CA). •Putnam Kia Burlingame visits (7/31/25 and 8/29/25) involved seat motor repairs, multi-point inspections, and tire-pressure checks only. No wheel removal or rotation occurred there as per their confirmation. •Kia Fremont has performed all wheel/tire-related services and recently discovered the damage. •Photos show damage across two wheels (3 studs stripped on one, 2 on another). This suggests a consistent pattern of improper service (over-torquing or cross-threading), not isolated wear. Safety Concern: The vehicle is currently undriveable. Multiple compromised studs across two wheels increase the likelihood of wheel detachment while driving — posing a severe hazard to me, my family, and other motorists. Manufacturer Response So Far: •Kia Fremont has ordered replacement studs but says parts will take ~7 days. •I am seeking Kia’s confirmation that all repairs and a rental vehicle will be covered under warranty.

Took my 4-month old Kia EV9 to a tire shop b/c I heard a rattling on the right side at low speed. Turns out both of the locking lug nuts had popped out of the front and rear hubs on the right side. Seems like someone at the port install facility in West Point Georgia didn't use the correct tools or torque settings. Turns out this is a known issue among a few customers per this Reddit thread: [XXX] I notified Kia CS. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The infotainment screen, including backup camera views, randomly glitches and then goes completely dark with no ability to view anything on the screen. The screen has been reset and software reloaded, but the glitch continues. Next, the screen was replaced but the glitch continues. This has been occurring since the beginning of June 2026.

I am submitting a safety complaint regarding a serious incident involving my 2025 Kia EV9. The vehicle was serviced on March 1 at World Kia in Joliet, Illinois. On April 4, only four days after that service, the vehicle experienced a sudden and unexpected ICCU failure while I was driving. During my normal travel, in active traffic and at speed, the vehicle abruptly entered limp mode and displayed multiple system warnings. This caused an immediate and significant reduction in power, creating a hazardous situation for myself and surrounding drivers. I was forced to maneuver the vehicle out of traffic while it was rapidly losing propulsion capability. The vehicle is currently at Berwyn Kia in Berwyn, Illinois for diagnosis and repair. I am reporting this incident due to the clear safety implications of a sudden loss of power during highway driving operation. A failure of this nature poses a risk of collision, especially in high‑speed or congested traffic conditions. I am requesting that NHTSA review this issue as part of its ongoing monitoring of Kia/Hyundai/Genesis Integrated Charging Control Unit (ICCU) failures and related safety concerns. Thank you for your attention to this matter.

This car is unusual because the wipers are located in a crevice far below the top of the hood where it meets the windshield. The first time we had an issue, it had snowed and snow collected in the crevice area. The wipers were turned on, but the drivers side one didn't move in sync with the passenger side one. They eventually "tangled" and we stopped them. The car was taken for service and supposedly repaired by replacing one of the wiper arms that had bent. It has snowed again. Before the snow fell, the crevice was mostly covered with a shield to keep snow from falling into it. The wipers were put into the "snow position" but when used again today, the wipers have again failed to operate in sync. The drivers side wiper doesn't move fully and the passenger side wiper does. Car wipers should work when it snows, but especially when precautions have been taken. This is extremely unexpected and atypical.

We just left the dealership in our new 2026 Kia EV 9 with 14 miles on it and as we were driving home the passenger windshield wiper started to make a loud banging sound when it would return to it ‘a starting position. We turned the wipers off and then turned them back on just to have the passenger one go half way a few times and then stopped working altogether. We live in Vero Beach Florida and this took place at [XXX]. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Seats allow drivers to save seating positions for different drivers. Seats automatically return to the last used saved position when the vehicle is turned on. This seat movement cannot be stopped or overridden without finding and activating the seat position controls on the left side of the seat base. If the driver does not find these controls in time, they can become crushed against the steering wheel or other surfaces. Seats do not respond to resistance and motors continue increasing torque until the controls are activated or the final saved position is reached. Problem is easily reproduced and may be related to recent fatality in Hyundai Palisade which likely shares components from Hyundai Motor Group.

Vehicle was delivered with an active safety recall on it. The safety recall is second and third row seat mounting bolts may be missing. Recall was announced December 2024 and car was purchased/delivered on March 20th 2025

The Kia EV9 Wind I bought several days ago worked fine for a couple of days with a slight vibration, but yesterday I experienced 3 incidents. 1. As I was coming to a full stop at a stop sign, there was a mild grinding noise from the rear of the vehicle. 2. I continued for 100 yards and came to a stop light and the car made a louder grinding sound of gears grinding as I was coming to a full braking stop. 3. I continued for about 1/2 mile. As I was coming to a stop at a stop light, there was a very loud grinding sound from the back of the car, like gears were being stripped, and the vehicle came to a full stop. At that point I was in the middle lane of a busy 3 lane road. I jumped out to inspect and saw nothing. I continued through the intersection and immediately pulled into a parking lot. I got out to inspect and there was a very strong burning smell coming from the driver side rear wheel well. I did not smell it on the passenger side rear wheel well. I had it towed to the nearby Kia dealership, and left it. This morning the dealership reported the initial diagnosis showed that the emergency brakes were activated while I was driving and they would report back later today on further diagnosis. They said the brake pads and rotors may need to be replaced and they would need to determine why the emergency brakes activated while I was driving. When I told them I was equally concerned about the grinding sound and the possibility of stripped gears, they replied that Kia Corporate does not pay them to explore potential problems that are not visible or obvious. My main concern is that there may be stripped gears to be replaced in addition to a software or other fix to prevent the emergency brakes from activating while driving. They also reported to me that there were 2 notifications with updates that had not been performed. One was for a software update for the rear powertrain and the other was for a sunroof issue and they would perform both.

Vehicle consistently vibrates at highway speeds, feels like a driveline vibration, wheel, tire or suspension issue. Almost feels like a tire is wobbling.

Within six months of purchase, the power steering on my 2025 Kia EV9 failed while I was driving, creating a sudden and dangerous loss of steering control. I brought the vehicle to the Kia dealership for repair, but it was returned to me without the problem being resolved. On the very first drive after service, the power steering failed again. This is a recurring safety defect that poses a serious risk to me, my family, and other drivers. The vehicle is unsafe to operate until the root cause is identified and repaired properly.

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.

My display with my backup camera started flickering. It then turned black and I couldn't see anything anymore and it was very dangerous to back up.

These Hankook iON Evo tires started vibrating wildly at the first service that I took the car to for a rotation. We took it back to the dealership (Ourisman Kia in Fairfax VA) three times where they kept the car for several days to diagnose. After opening the tires up, they state that the inner sound insulating foam on all four tires has separated. The tires were at 7/32 and now 5/32 and the car only has 18,200 miles on it. The tires have a 50k treadwear warranty, but this isn't covered as part of the warranty. The inner foam separation on a Kia EV9 is a known issue and widely discussed on the internet. For an $80k vehicle with OEM tires that cost over $1500 to replace, it's ridiculous that they aren't covered by the dealership or by Hankook.
