2024 Kia Sportage driver assistance problems

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 concern regarding the Forward Collision Warning and Automatic Emergency Braking systems on my 2024 Kia Sportage SX Prestige. I have been attempting to understand the operating behavior of the vehicle’s FCA system using cardboard boxes as targets. I conducted observations at very low speeds (approximately 5 mph) as well as at approximately 30 mph. During these observations, the vehicle did not provide a forward collision warning or automatic braking at distances at which I expected the system to recognize a potential collision. I have not intentionally caused a collision or placed a person or another vehicle in danger. I am uncertain whether this behavior represents normal FCA operating limitations, the use of an inappropriate target, or a malfunction or calibration issue. I am therefore reporting the concern rather than asserting that a defect has been established. I am also uncertain what diagnostic or functional validation procedure Kia provides for this system. I have been able to find information regarding radar alignment, camera calibration, and diagnostic fault checking, but I have not been able to determine whether Kia provides dealers with a standardized functional test that verifies that FCW/AEB actually recognizes an appropriate vehicle target and intervenes at the expected point. The concern has not yet been reproduced or confirmed by a dealer or independent service center. The vehicle has not yet been subjected to a standardized ADAS functional test using a recognized vehicle target. No warning lamps or diagnostic messages have appeared that I am aware of. The potentially affected components are Forward Collision Warning and Automatic Emergency Braking within the vehicle’s Advanced Driver Assistance System. The vehicle is available for inspection upon request.

Blank Instrument Panel Screen. abnormal CAN message which can cause certain instrument clusters with a 4.2” screen to reboot while driving. During this rebooting, the cluster will not show information such as the speedometer or telltales for approximately five (5) seconds. As a result, the subject vehicles do not comply with the visibility and illumination requirements of FMVSS 101, §§ S5.1.2 and 5.3.1

Two issues that I've taken to dealership 3 times since purchasing vehicle January 2024. 1. Adaptive cruise control -- I was in right lane of 4 lane highway with cruise control on. A car in left lane took a turn to cut through median and my car thought it was a collision and hard braked and took my vehicle from 60mph to 35mph in a few seconds. If a car had been behind me, I would have been rear ended. They cannot "replicate" so I no longer use cruise control unless there are no cars around. 2. Timing has been off (loud clicking every time I crank) since a few months after I bought the car. I sent approximately 9 videos to the service advisor. Took it in 2 times "cannot replicate." Left it overnight at dealership "cannot replicate." It's every time I first crank for the day. It's now louder and gotten worse. I have videos and can take more. I just want this fixed. Afraid I'll be stranded and it feels like they are pushing it farther and farther out so it will exceed warranty and they won't have to eat the cost to repair. It's been 1.5 years I've been dealing with this. Any help you can provide is greatly appreciated!!

Description of Crash: On [XXX], I was involved in a front-end collision while driving my 2024 Kia Sportage. Despite the impact, the airbags did not deploy. Additionally, the Forward Collision Assistance system did not engage or warn me prior to the crash, even though conditions were normal and the system was active. Safety Concern: •The airbags and collision assistance are federally regulated safety systems. Their failure put me and any potential passengers at serious risk. •I am very concerned this indicates a defect in the airbag and/or collision avoidance system. Damage/Injuries: My front end of my vehicle is completely destroyed, and so is my engine. As for myself I am experiencing some soreness and discomfort Requested Action: •I request that Kia and the federal safety agency investigate this failure as a potential safety defect. •I want confirmation that my case has been documented and reviewed for possible recall or repair action.
