   The digital rearview mirror system intermittently fails while in use. The image in the rearview mirror will start flickering and eventually go completely black while driving. The system has been inspected and serviced multiple times by the dealership under warranty but the problem keeps recurring.

   So I called KIA about this, but I wanted my report to appear here too. Back in February, my right foot was run over by my car. It was an accident. I had gotten out of the driver's passenger side to check on something that was making noises. The person who ran my foot over didn't realize I was out of the car, and there was no warning; there was no noise indicating my door was open. Then the back driver-side tire ran over my foot. My foot was broken in a few places, and I was in a shoe boot for quite a while. It is very dangerous to think there was no alert; I can't imagine if this happened to a child. I was pretty thorough in telling them what happened, and nobody ever tried to compensate me or do anything about my situation. It is a major hazard to have your foot run over because the car is super heavy because of the battery. I'm lucky my foot healed, and I didn't need any further treatment.

   I was sold a vehicle with a manufacturer defect. At purchase there was a loud wind noise coming from sunroof. I was promised a swift service department visit to realign the sunroof. At service visit ten days later the dealership replaced sunroof and threw electrical error codes B271100. After a specialist over rode the error the dealership claimed fixed and had me pick up the vehicle. The loud wind noise was still present. When I attempted to return the vehicle the dealership said I would no longer be serviced by their dealership. Kia Customer Care sent me to a second dealership. Second dealership brought in techline specialist that ordered Kia Warranty repair would replace the entire roof. The vehicle is at a third party auto body repair shop.

   The contact owns a 2026 Kia EV9. The contact stated that while driving 25 MPH and accelerating through a four-way intersection after a complete stop, the vehicle was T-boned on the front passenger’s side by another vehicle that had ran the stop sign. The passenger’s side air bags deployed as expected, and the driver’s side air bag also deployed, causing a fractured right humerus. The contact required emergency surgery. The contact was pregnant at the time and remained hospitalized for two days. The doctors established a post-surgical recovery plan. The contact’s minor child, who was seated in a car seat on the rear passenger’s side, was not hurt. A Police report was filed. The vehicle was towed to an independent mechanic. The insurance company had not yet determined if the vehicle was a total loss. The dealer was notified of the failure and directed the contact to an online crash test video suggesting that the front driver’s side air bag should not have deployed in the crash. The manufacturer was not notified of the failure. The failure mileage was 1,200.

   I am reporting a total of 6 failed lug bolts on the rear tires of a 2026 Kia EV9 GT-Line within 1 year of ownership. This vehicle was purchased in Aug 2025 as a new vehicle from a Kia dealership. In March 2026, vehicle was brought for it's 8000 miles service at a Kia dealership. At the time the vehicle had 9336 miles. During tire rotation, service technicians found passenger rear wheel to have a broken lug stud. From the service records, "No evidence of outside influence." This was replaced with new. Prior to this, the passenger rear tire was never serviced. On 8/7/2026, a bystander informed myself of an abnormal sound coming from my driver rear tire. The wheel center cap was removed and 3 broken lug bolts were found. The broken lug bolts were sheared off at the base of the lug nut. This tire was being held on by 2 of 5 lug bolts, representing a significant safety concern. With 2 of 5 bolts, the remaining 2 bolts are under significant stress and can break at any time potentially causing the tire to fall off of the vehicle causing loss of control, potential accident and injury or loss of life. With the discovery of the broken 3 bolts, the car was taken to a kia dealership for repair. During this service it was also noted that on the same wheel (driver rear) one of the 2 screws that hold on the rotor was broken off as well. For completeness, this tire had been serviced once before at Les Schwab tire, on 9/17/25 (1733 miles on odometer) due to a piece of metal in the tire. All lug nuts torqued to factory recommendations. On 8/27/26, the car was taken to Les Schwab for a tire rotation and balancing (18,627 miles). When the technician began removing the lug nuts from the passenger rear tire, two of the bolts broke. The car is driven only on paved roads at street and highway speeds. No accidents or damage to the car that could explain shearing of lug bolts.

   The car was being parked in a shopping lot. As the drive was pulling into the parking spot, the car lurched forward on its own and hit the wall. The gas pedal was not pressed. No collision sensors were triggered either. Unclear if related but the car was taken in for maintenance and recall updates the week prior to this accident.

   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 onset of this issue due to safety concerns. The problem was confirmed by the Kia dealership service advisor who performed a road force balance on June 15, 2026 — the technician confirmed the front two tires were off balance and needed replacement (but didn't save the report, their mistake). The road force balance did not resolve the issue. The service advisor also verbally confirmed that multiple other EV9 customers at the same dealership are experiencing the identical issue with no resolution, and that one customer has been waiting over three months while driving a loaner vehicle. The vehicle was inspected by the Kia dealership on June 12 and June 15, 2026. Kia Consumer Affairs was contacted and a case was opened on June 22, 2026 (Case #26202152). The assigned case manager never contacted me despite three follow up calls over three weeks. Kia Consumer Affairs ultimately directed me to contact Hankook — however Hankook's own published warranty process requires claims to be filed through authorized dealers, not consumers. There were no warning lamps or messages prior to onset. The vibration appeared suddenly at approximately 7,400 miles. The vehicle drove normally for several months prior to this onset with no vibration at any speed. The sudden onset after months of normal operation confirms this is a defect, not a vehicle characteristic. The issue has persisted since first appearing. *Video documentation of the vibration at highway speed is available upon request*

   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 failed to resolve either concern. A Kia Field Technical Specialist attributed the vibration in writing to the vehicle’s design (center console and floor-mounted captain seats). An independent inspector arranged by BBB Auto Line confirmed both defects on July 2, 2026. This appears to be a platform-level issue affecting multiple 2026 EV9 vehicles based on owner reports.

    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, multiple road force balances, and alignments. The dealer has now tested the vehicle with the original factory wheels and tires, an aftermarket set, and a known-good set of wheels and tires from another EV9, and confirmed in writing that the vibration is still present in all three configurations. The dealer has additionally found excessive road force on the original factory tires on two separate occasions. The dealer has advised me that Kia may consider this a normal characteristic of the model and that no further repair is expected. No crash or injury has occurred.

    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 1 was an exit only offramp. Once I got to the side of the road, I power cycled the vehicle. when that didn't revolve the red turtle issue. I pressed the frunk open button. I heard the opening mechanism actuate. I then reseated the frunk latch and closed the frunk. Once the vehicle was turned back on, all issues were resolved and the vehicle behaved as normal.

    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 the span of 20 days, indicating a severe structural vulnerability, manufacturing defect, or excessive frame tension that makes the glass highly fragile under normal driving conditions.Component Availability: The vehicle and the cracked windshield component are currently intact and available for inspection upon request.Safety Risk: The rapid propagation of the cracks across the driver's field of view creates an immediate visibility hazard while navigating at highway speeds. Furthermore, the brittle nature of the glass compromises the structural integrity of the windshield, which is a critical safety component for roof crush protection and proper passenger airbag deployment in the event of a collision.Dealer/Independent Confirmation: The vehicle is being scheduled for an inspection and full windshield replacement at an authorized automotive glass repair facility to address the structural failure.Inspections: The damage is currently being documented and inspected by my comprehensive auto insurance provider as part of the replacement claim process.Warning Symptoms: There were absolutely no warning lamps, messages, or prior symptoms. The failure occurs instantly upon the smallest impact due to what appears to be extreme built-in structural tension.

    While making a left turn at a four-way intersection, the passenger side front door opened the latch failed. This vehicle is equipped with motorized door handles that retract/flush when the vehicle is in drive indicating that the doors are locked. The door handles were retracted while driving the vehicle and making the slight left turn. During the turn, the passenger side front door opened and was a jar that could be indicated on the dashboard as well. This would put anybody at risk sitting in the passenger seat or causing an accident from the malfunction and alarm of the door. The vehicle was examined by a service department of a Kia dealership and parts of the door latch and or handle were replaced according to the repair order.

    On March 19, 2026, at approximately 1003 hours, I was traveling north on the [XXX] located in [XXX] . I was traveling in the number two lane and my speed was approximately 78 MPH when all of a sudden I had a loss acceleration power and my Kia EV9 began to decelerate rapidly and my dashboard began to flash a loss of power warning. I had no control over my accelerator and could not speed up. Due to the rapid deceleration I had to take evasive action as northbound highway traffic was flowing smoothly. My clearest path was to move to the lefthand shoulder, which required me to cross the number one lane and the carpool lane. During this time, my Kia EV9 continued to decelerate. Once I got my vehicle onto the shoulder I placed my vehicle in park at which time my dashboard highlighted the front storage compartment of my vehicle in red. I assumed that meant my frunk was open. I exited my vehicle and checked my frunk and indeed found that my frunk was open and the first stage of the two-stage latch system was disengaged. Had the second stage of the latch system been disengaged it could have resulted in catastrophic consequences due to me traveling at highway speeds on a multilane highway. To be clear, I did not touch the interior compartment frunk release button and my keys were sitting in my left cargo short pocket located on the side of my left leg. I had also been traveling for approximately five to seven minutes and had entered the highway via the northbound [XXX] . I came to a stop at approximately the [XXX] area, which is approximately two miles north of [XXX] . I am aware that electric model Kia vehicles have a safety measure in which if the frunk or trunk is open the vehicle computer system does not allow the vehicle to engage in drive or reverse mode. Since I do have an electric vehicle, a diagnostic of my vehicle computer could reveal the cause. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

    The first time I drove on a highway in this brand new car the windshield chipped. There are facebook group posts of other drivers experiencing numerous chips and cracks in the windshield. I'm not sure how this compares with other cars, but I've been driving for about 20 years and have had little rocks/pebbles hit the car windshield and never have had an issue with a chip in the windshield. I'm not sure how unsafe this is-- if the entire thing could break-- the dealership I go to is patching it for me-- but this may be a consumer issue and possibly a safety issue too.
