Engine
The vehicle experiences an intermittent, severe safety malfunction tied to the Idle Stop & Go (ISG) auto-stop system. When brought to a complete stop at intersections or red lights, the engine shuts off normally to conserve fuel. However, when releasing the brake pedal, the engine completely fails to auto-restart and stalls out in live traffic. The vehicle locks up, flashes an error message on the instrument cluster instructing the driver to shift to Park or Neutral to restart, and requires a hard manual key cycle to get the vehicle moving again. This intermittent defect has occurred over the past year, creating an extreme hazard for rear-end collisions in high-traffic intersections. The…

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 systemsâincluding Forward Collision-Avoidance, Blind-Spot Monitors, and Electronic Stability Controlâinstantly 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…

On XXX, while driving my 2024 Kia Sportage X-Pro Prestige on [XXX] after exiting XXX, traveling west toward [XXX], the panoramic moonroof glass suddenly shattered without warning. It sounded like a gunshot going off very loudly inside the vehicle and badly startled both me and my service dog. The glass had no known prior damage, nothing had been placed on it, and I did not see or hear anything strike it. I pulled over and found the panoramic glass extensively shattered, with thousands of small fragments and areas of glass missing. I saw no evidence of an external impact. I received a superficial cut to my finger from a glass fragment; no medical attention was required. The interior sunshade…

My 2024 Kia Sportage X-Pro Prestige has experienced at least 3 intermittent, unexpected engine shutdowns while driving or in traffic. The cause remains unidentified. The first occurred before [XXX] (exact date unknown). While stopped at a red light in Drive, I realized the vehicle had completely shut off. The engine was not running and all screens/displays were black. There was no warning. On [XXX], the same failure occurred without warning at approximately 60 mph during a longer highway drive. The engine shut off and all screens went black. I nearly collided with an 18-wheeler. No collision occurred. I was directed to call 911, and the vehicle was towed from the highway to a Kia…

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…

The SRS/airbag warning light illuminates and flashes, accompanied by a seat belt warning chime while the driver seat belt is fastened. I scanned the SRS module and retrieved DTC B1511-00 (Driver Seat Belt Buckle Switch Open Or Short To Battery) and B1515-00 (Driver Seat Belt Buckle Switch Defect), logged across two events. I purchased this vehicle used from a franchised dealer. I took it to that same dealer for diagnosis. Their technician found that the wiring harness under the driver seat had been cut and twisted back together. That splice was present before I purchased the vehicle. The dealership inspected and resold the vehicle to me in that condition and did not disclose any prior…
Sep 1, 2026Forward collision avoidance › Automatic emergency braking
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 vehicleâs 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…
