Kia EV9

When I started the car up, I noticed a little bit of chattering on the brake pedal, which seemed very unusual. I drove the car forward a little bit and then all of a sudden, all these lights displays and stop vehicle and check brake system now message showed up. The car was very sluggish to drive and had almost no brake pressure. I was able to drive it out of the parking lot (slowly and carefully). When I called a tow truck, I left the vehicle off for about 20 or 30 minutes, and then when I…

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.

The OEM Hankook iON tires (285/45R21) on my 2026 Kia EV9 GT Line experienced acoustic foam delamination — the sound-dampening foam bonded to the interior liner of the tire separated and is moving freely inside the tire at highway speeds. At speeds above 55mph the steering wheel and car start to vibrate. At 70mph the vehicle becomes undrivable and feels as though the wheels may detach. This creates a serious and immediate safety risk to myself. I have largely avoided highway driving since the…

Beginning at approximately 104 miles (shortly after delivery at 75 miles), this vehicle exhibits a persistent vibration felt through the steering wheel, seat, and floorboard at highway speeds — specifically beginning around 55 mph, again at 61–63 mph, and most noticeably between 68–74 mph. A second defect involves rear-end instability where the rear of the vehicle feels loose and sways side to side over bumps and at higher speeds. Five repair attempts across two authorized Kia dealerships have…

Since taking delivery on June 20, 2025, this vehicle has exhibited a vibration at highway speeds, most severe at approximately 72 mph. The steering wheel visibly shakes and the vibration is felt through the steering column. It is fatiguing over long drives and I have become unwilling to use the vehicle for family highway travel. I reported it to the selling dealer within days of delivery. Authorized Kia dealers have attempted repair four times over thirteen months, including tire replacement,…

I was driving down the freeway driving at the speed of traffic. My vehicle started beeping aggressively, a red indicator started flashing over the frunk area of the vehicle representation in the dash and my vehicle entered red turtle mode. This red turtle mode severely reduced the vehicle's speed and ability to maneuver on the freeway. I was almost struck by numerous vehicles while attempting to get to the side of the road. I had been driving in the number 3 lane of a 5 lane freeway where lane…

The vehicle's front windshield glass failed catastrophically from minimal, routine roadway debris on two separate occasions within a single week.While driving at normal highway speeds, a microscopic stone or pebble impacted the windshield. Instead of causing a minor, isolated cosmetic chip, the acoustic laminated glass immediately developed an expansive linear stress fracture that rapidly spread across the driver's direct line of sight within minutes. This identical failure occurred twice in…

For several weeks the car has felt out of balance and I had it in the shop once to be balanced. The balance felt it lasted a very short time. I took the car in today to be checked out and the passenger rear tire couldn’t hold a balance. Mechanic removed tire and the interior sound deadening foam had detached on greater than 50% of the diameter of the tire. This has been widely commented on as a common failure mode for these Hankook tires on EV9 vehicles. I wanted the remaining tires inspected…

When making left turn or going over bumps, driver seat pops and feel shifted.

What component or system failed or malfunctioned, and is it available for inspection upon request? Two components failed simultaneously: (1) the rear passenger side tire experienced a catastrophic blowout while traveling at 65 MPH on the highway, and (2) the Tire Pressure Monitoring System (TPMS) failed to detect or warn of any tire pressure abnormality before or after the blowout. Following the blowout, the vehicle’s diagnostics screen displayed “All Systems OK” while the instrument cluster…
