2024 Kia EV9 driver assistance problems

Filed Oct 22, 2026 · Body, Driver assistance · TX

In July 2024, approximately two months after purchasing the vehicle new in May 2024, a significant spiderweb-shaped crack developed in the front illuminated grille and fascia assembly. The vehicle had approximately 300 miles on the odometer and the damage was discovered during a routine hand wash. The vehicle had only been driven under normal roadway conditions in the Corpus Christi, Texas area with no collisions, accidents, or known abnormal impacts. This exposed acrylic-style front fascia houses the GT-Line's digital lighting elements and protects critical front-mounted safety sensors and sophisticated electrical systems. The structural failure of this panel compromises the weather sealing, exposing sensitive high-voltage components and advanced driver assistance system (ADAS) sensors to moisture and road debris. This poses a potential safety risk regarding electrical system integrity and sensor reliability. The vehicle was immediately presented to the original purchasing Kia dealership. The dealer ultimately replaced the entire front grille assembly at no charge under warranty. However, the replacement component utilized the identical structural design and materials, failing to correct the underlying vulnerability of the fascia to ordinary highway exposure.

On my 2024 Kia EV9 GT-Line, the front illuminated digital pattern acrylic/plastic grill panel suffered a catastrophic structural failure, resulting in a complete blowout and puncture hole under normal driving conditions. The panel fractured and shattered completely while driving on standard paved roads, with zero history of front-end collisions, low-speed impacts, or road debris strikes. This indicates a severe material strength, thermal stress, or structural design defect where the acrylic housing cannot withstand normal operational driving forces. Given its placement over critical forward-facing ADAS sensors, cameras, and electrical lighting elements, this open hole and structural failure presents a severe safety, sensor compromise, and moisture/debris intrusion hazard. I am submitting this report to document the defect and wish to cross-reference existing complaint number 11589157, as multiple owners are experiencing identical structural failures of the illuminated grill panel under normal driving conditions. Requesting a federal investigation into material durability and a manufacturer-backed recall.

On September 10, 2026, while driving my Kia EV9 on a public roadway, I experienced a suspected unintended and excessive activation of the vehicle's collision-avoidance/automatic emergency braking system. I was traveling straight in my lane when another vehicle approached from the right side and crossed/moved into the roadway ahead. The other vehicle continued moving away from my immediate path; however, my EV9 suddenly applied substantial braking without me commanding that degree of braking. The incident was captured on my front dash camera. The recording shows my vehicle traveling approximately 31 MPH shortly before the event. The recorded speed decreases from approximately 30 MPH to 28 MPH, then rapidly to approximately 15 MPH and approximately 7 MPH within only a few seconds. The unexpected braking created a serious safety concern because a vehicle traveling closely behind me could have struck the rear of my vehicle. There was no collision, and fortunately no vehicle was immediately behind me. I retained the original dash-cam recording and can provide it for inspection upon request. The vehicle is also available for inspection. I have since disabled the collision-avoidance feature because I am concerned that another unintended braking event could occur at highway or roadway speeds. I am reporting this incident because the driver-assistance system appeared to intervene more aggressively than the traffic situation required and temporarily took braking control away from the driver. I am requesting that the federal safety agency document and evaluate this incident for possible similar complaints involving Kia EV9 collision-avoidance or automatic emergency braking systems.

[XXX] Message says warning "check ev system". they then sent a letter saying it had to go to the dealer, or the car would need A tow potentially. I can't get an appointment as they are way too busy to do anything other than tell me they will get back to me, repeatedly stating they will do so in one business day. it has been a week. My wife is scared to drive the car. I think it is bogus as no recall has been issued. I have had the car for 19 months with no such warning. Two days after it shows up on the screen in the car i receive the letter. This is fishy. it is either a recall, or it isn't. if it is why is it not in your data base? The vagueness of the message is inappropriate, and it implies danger. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The dashboard and control panel of my vehicle have repeatedly blacked out since shortly after purchase. These blackouts cause the entire instrument cluster and control systems, including critical safety features, to become non-functional or obstructed intermittently while driving. This creates a dangerous situation where I lose access to important information such as speed, warning indicators, and climate controls, severely compromising my ability to operate the vehicle safely. The issue has occurred multiple times, including once while driving on a highway, which put me and other drivers at significant risk. The problem has been reported to authorized dealerships, where the vehicle was inspected and software updates were attempted, but the issue persists. Despite multiple repair attempts, the blackouts continue to happen unpredictably. There have been no specific warning lamps or messages prior to the blackouts; the system simply fails without notice. The malfunction affects the vehicle’s safety system by obstructing the driver’s view of critical controls and information, increasing the risk of accidents. Customer service from the dealerships has been unsatisfactory, with long wait times for repairs, lack of loaner vehicles, and repeated failure to resolve the problem. This ongoing safety concern remains unresolved despite numerous visits and repair attempts.

Certain ADAS features have disengaged at least six times in the last year. While traveling at greater than 55 mph vehicle disengages cruise control and reports numerous warning indicators on dashboard including ADAS forward features such as collision warning and automatic braking indicators. I also noted lane management/steering also seemed to disengage when this has occurred during highway curve management. It is difficult to evaluate the full range of loss as the dashboard warnings are numerous and change over the next few minutes. It is also unsafe to secure good photographic evidence when traveling alone, though with assistance some imagery was recently captured. The sudden loss of speed and directional control assistance in multi-lane urban traffic was alarming but managed OK by alert driving. The manufacturer's dealer reported they could do nothing after one of the first occurrences. They said there were not 'codes' registered and not reports on file. The loss of systems usually cleared up within a few miles for the first instances. The most recent case persisted for several hours and several vehicle off/restart cycles. During this time the dashboard indicators suggested some failures resolved but some remained. This last case cleared over-night upon morning restart. A failure/warning was noted in the Kia Connect online app while the car still reported a problem. There were no prior indications before the sudden systems failure. All of these cases initially occurred on a section of road within about 1/2 mile of the same place. It involves a significant curve on an urban interstate interchanged. Sometimes the failures occur just before, or during, and at the end of the curve.
