2026 KIA EV9 Saratoga, CA Crash

FORWARD COLLISION AVOIDANCE: WARNINGS

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.

FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING

[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)

2024 KIA EV9 Huntsville, AL

FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL

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.

2024 KIA EV9 Chattanooga, TN

FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL

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.

2024 KIA EV9 Algonquin, IL

FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING

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.
