Kia Sportage lane assist problems

Filed Oct 21, 2026 · Driver assistance, Electrical · FL

1. COMPONENT & INSPECTION: Electrical System / CAN-Bus network architecture and gateway modules. The vehicle and parts are available for inspection upon request. 2. SAFETY RISK: The CAN-bus drops communication while driving at road speeds. Critical safety systems—including Forward Collision-Avoidance, Blind-Spot Monitors, and Electronic Stability Control—instantly shut down mid-trip. Losing active stability and driver assists while moving on public highways poses an immediate, severe crash hazard to myself and others. 3. DEALER CONFIRMATION: Yes. An authorized Kia dealer scanned the vehicle and confirmed multiple logged historical network communication error codes (U-codes), verifying a system-wide network failure. 4. OTHER INSPECTIONS: Inspected only by the Kia dealer technician. However, because the failure is intermittent, the dealer simply cleared the fault codes and released the vehicle without performing physical diagnostics or repairs. Kia America Corporate opened a consumer case but has since ghosted all communication. No police or insurance inspections have occurred yet as a crash has not yet happened. 5. WARNING LAMPS & FIRST APPEARANCE: No advance warnings occur. The failure happens instantly mid-drive. Symptoms include a sudden, simultaneous "Christmas tree" illumination of warning lights (Stability Control, Braking, and Lane Assist). These symptoms first appeared in September 2026 and recur intermittently.

I purchased a used 2024 Kia Sportage EX Gas that showed signs of trim peel at 5,000 miles. My extended warranty said they do not cover trim. I noticed multiple cars in our parking lot experiencing the same issues on 2024 or older models. In addition, the low gas indicator does not appear on the infotainment system after the Kia Connect expired despite gas being as low as 32 miles projected (avg. 24 mpg normal range). The Sportage lane assists yellow indicator comes on sporadically when changing lanes without or with the turn signal on. The steering assist will turn off when you go through a intersection and is not reliable enough to even turn on as it will give you a false sense of protection and intimately turn off.

I am reporting a potential safety issue involving the lane assist system on our Kia Sportage. On Monday morning, my wife was driving on a straight road and began turning left onto a side street. During the turn, the vehicle’s lane assist system suddenly applied a strong steering correction. The steering wheel jerked unexpectedly and momentarily resisted the driver’s attempt to correct the steering. This sudden steering intervention caused the vehicle to veer toward a guardrail, resulting in a collision. The driver did not intentionally steer toward the guardrail and attempted to correct the vehicle, but the steering wheel resisted input at the moment the lane assist system intervened. A dashcam in the vehicle recorded the incident, and the responding police officer reviewed the footage at the scene and concluded that the steering wheel jerked toward the guardrail. The police report notes that the accident appeared to involve a possible vehicle malfunction. After the incident, we discovered that this vehicle is included in the federal safety agency Campaign 26V046000, which states that a software error may cause the instrument panel display to fail to show critical safety information such as warning lights. If a malfunction warning occurred but was not displayed, the driver would not have been aware of a problem with the system. The lane assist feature in this vehicle also automatically reactivates each time the vehicle is started, meaning the driver cannot permanently disable it. Because the steering intervention occurred unexpectedly during a normal turn and resulted in a collision, we are reporting this incident so it can be reviewed as a potential safety defect involving the lane assist or related vehicle systems.

I turned on my vehicle and began driving in Philadelphia. I noticed the dashboard where the speedometer was supposed to be was dark. The Apple car play on the right side of the dashboard was on but no other components were visible. Such as turning signal, lane keep assist, speedometer, etc. I was on the highway and this was extremely scary. This vehicle has less then 200 miles. I’ve taken it to Kia and they are looking into it. But this is a big concern. I have videos of this but it won’t let me add them to this file.

Dear Sir or Madam, My car was hit by another car when I tried to switch to the next lane. I did give a turning signal and observed before switching. However, a car sped past and hit my car. If the detection system had sounded an alarm at that time, I wouldn't have changed lanes at that moment. Unfortunately the Lane Assist and Blind Spot Detection System was not functioning correctly and failed to provide a warning. This malfunction didn't occur only once, it happened again after this accident(no consequences though).I gave feedback to Kia and I believe my detection system is not working consistently. I requested an inspection on my car. Kia refused to repair the damaged areas for inspection purposes, instead, they pushed OTA updates into my car, and they pushed twice within two weeks without informing me. I asked Kia if the existing issue still could be detected as they pushed the OTA updates. They didn't answer despite me asked twice. Feeling quite helpless, I searched and noted another person's Kia had the same issue: detection system not working consistently. I realized that I will be unable to prove that this vehicle had pre-existing issues due to the OTA updates. I'm worried that Kia might use this as an excuse to refuse to repair the damaged areas. I understand I cannot totally rely on the detection system, but this feature can enhance safety if it works well, at least I would pause and not act if it provides warning properly. Thank you.

I was driving on the highway and encountered a slick spot. The lane keeping assist and braking caused the car to veer to left to try to stay in the lane, which in turn caused the car to spin around twice. The car need to turn in the direction of the spin which was not possible because the lane assist was controlling the steering wheel.

On November 25, 2024, the dash and infotainment screen went blank while at the traffic light. A few seconds later the car stalled shutting completely off while making a left turn onto Cox Rd in Evans, GA. We were able to coast out of traffic and came to a complete stop on the side of the road. We attempted to restart the vehicle and multiple warnings appeared on the dash such as check forward safety system, two cars colliding, check blind spot safety system, traction?, ABS, lane departure, seat belts, Auto Hold, and other symbols not understood. On the second attempt, the vehicle restarted and more warning symbols appeared as soon as it was put in drive. The vehicle was shut off and restarted again with no warnings. We proceeded and drove it to Kia of Evans for service. The service Rep reported that the vehicle was driven 5 miles and they were not able to duplicate this issues. The infotainment screen has blanked out several times since purchase and this is the second time the vehicle has stalled at a traffic light. On this incident, this could have been a traffic situation turning left and losing power into oncoming traffic.

My vehicle intermittently starts with the blind spot warning, lane departure warning, rear cross traffic warning (and rearview camera), defoggers, and AC/heat not functioning. When this happens, the temperature control knobs are hardly visible and the car will flash “Battery Discharge Warning” on the display screen for several seconds. An error code also appears in the Kia App when this issue happens. The error code immediately goes to history error codes so the dealership service center has not yet spent time to investigate the issue. The car has been to the dealership twice and the service advisor has witnessed the issue.
