[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.

While driving, the vehicle suddenly lost power and could not accelerate normally. The speed dropped and got stuck around 12–25 mph even when pressing the accelerator. This happened multiple times, usually during hot daytime conditions. It created a serious safety risk, and one time another car almost hit me from behind because my vehicle slowed down so suddenly. The dealer has inspected the car several times but said they could not reproduce the problem. Warning messages such as “Power Limited” appeared on the dashboard when the failure occurred. I also recorded multiple videos of the problem when it happened.

I was driving around 60-65 mph on the highway when suddenly a warning alarm went off and the warning light read “stop vehicle and check brake system”. I took my foot off the accelerator and car continued to maintain speed. The power brakes did not work. I put the car into neutral hoping that would slow it down, but it continued to maintain speed. I went into the right lane and put on my hazards. When I had the opportunity to pull into the breakdown lane, I did so and was able to push the brake pedal manually and get the car to stop, and turn it off. When I turned the car back on again, I got the same warnings and alarms. After 5-10 minutes, when I turned the car on, everything seemed to have cleared. I still had the car towed to KIA to investigate the issue.

What happened? While driving at highway speeds (approximately 60-75 mph), the vehicle exhibits a pronounced up-and-down motion at the rear, commonly referred to as “porpoising.” This motion is especially noticeable when traversing uneven road surfaces or expansion joints. This issue compromises vehicle stability and passenger comfort, posing a potential safety risk during high-speed travel. The problem has been consistently reproducible under similar driving conditions. The vehicle has not yet been inspected by a dealer or independent service center for this specific issue. No warning lights or error messages have appeared on the dashboard in relation to this problem. Component suspected: Rear suspension system (exact cause UNKNOWN). I am willing to have the vehicle inspected upon request.

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.

My EV9 lunged forward very abruptly when I was parking. I had to slam on the brakes before my vehicle crashed into the building in front of me. My vehicle also lost the signal (blank screen while driving ) the same day my car lunged forward. I could not tell how fast or slow I was going. I pulled over and restarted the vehicle or and my screen came back on. I began driving for maybe 4 minutes and the screen went completely black except for the “lost signal” alert in red. My vehicle has also lost the ability to use adaptive cruise control while driving my vehicle. I pulled over and when I restarted the vehicle i was able to use it again.

On November 5th, 2024 I exited a store and my vehicle instrument panel was black when I turned my vehicle on. I turned my vehicle off and on several times trying to get the panel to work. I could also not control the headlights or turn signal with the manual controls either. It was still daylight hours and I was 2 miles from home so I decided to try and see if the vehicle could be driven home. I was able to get the vehicle home but could not get the instrument panel to turn on despite many more times of trying by turning the vehicle off and on. The following morning I contacted the Royal Kia dealership and told them of my issue and they informed me this was a known recall issue that had recently been discovered; they had the vehicle towed to them the same day. They have now had my vehicle for 2 weeks and when I called them before filing this complaint they said they had no idea when they would be able to fix the recall. They also told me they required a special tool to fix the recall and they do not have that tool and have no idea when they will be able to get it. I then called another local Kia dealer and they told me they would also not be able to fix my vehicle in a timely manner and it would be 2 months before they would even be able to diagnose my car. My complaint is that the recall letter claims this is just a software update that could be done without visiting a dealership but both dealerships are telling me that it has to be fixed in person by them.

I was driving down the highway at approximately 60 mph with approximately 40% charge to the high voltage battery. While moving the car suddenly stopped accelerating and switched to neutral automatically. The instrument panel provided no audible alerts of a problem and in relatively small text stated "check electrical system" The brakes and the rest of the car's electronics worked such as turn signals and warning lights. We were able to coast and pull over to shoulder of highway and stop safely, but losing acceleration in middle of highway suddenly was very scary. Car is currently at dealer awaiting to be diagnosed.

I recently had recall 24V693000 completed on my vehicle. After the recall while using the remote vehicle movement feature it no longer stops at all. While demonstrating the feature for a friend interested in purchasing a similar vehicle it did not stop and I had to move and release the remote to stop the vehicle. I have tested it again twice and the same problem occurs, the vehicle does not detect a pedestrian behind it and does not attempt to stop or stop.

When the vehicle is in adaptive cruise mode and tracking a lane with Lane Keeping Assistance, if the lines on the road widen beyond a certain point (perhaps 3-5ft wider than a normal lane), the vehicle will suddenly stop maintaining the lane with no audio warning or significant visual indicator. As the driver should always be paying attention, it is the lack of an audio warning that is the major concern. On a straight road, the vehicle will slowly begin to drift out of the lane. However, when this happens on a curve, the vehicle will suddenly stop steering around the corner, and throw the vehicle out of the lane in a dangerous way. This happens all the time when the lane widens, which I often experience on newer freeways with wider lanes. If a fix can't be provided for the system shutting down, it at least needs an audio warning indicator so the driver is alerted to what is happening and can safely take control.

I am reporting a critical safety issue with my KIA EV9. The vehicle's information screen, which displays essential driving data such as vehicle speed, cruise control status, advanced driving system indicators, lights, and signals, has malfunctioned. On two separate occasions, the screen went completely black while driving, leaving all critical driving information inaccessible. This malfunction poses a significant risk to my safety and the safety of others, as I was unable to monitor the vehicle’s speed or system status while driving. Availability for Inspection: The malfunctioning component (information screen/system) is available for inspection upon request. Safety Risk: This issue compromised my ability to safely operate the vehicle. Without visibility of the speedometer, driving system indicators, or signal lights, I was unable to monitor crucial driving functions. This increased the risk of speeding unknowingly and reduced my ability to respond to surrounding traffic, creating a dangerous situation on the road. Reproduction of the Problem: The issue has occurred twice. While I have not yet had it reproduced or confirmed by a dealer or service center, I am aware that other KIA EV9 owners have reported the same issue, indicating it is not an isolated case. Inspection by Others: To date, the vehicle has not been inspected by KIA, law enforcement, insurance representatives, or other authorities regard Please find below links to forums and websites where other KIA EV9 shared about this issue. 1- [XXX] - [XXX] - [XXX] - [XXX] Here is the video of the incident.
