Is there a fix? Manufacturer service bulletins
The manufacturer has issued service bulletins covering electrical on this vehicle — documented repair instructions, service campaigns, or warranty extensions sent to dealers. A TSB isn't a recall (it's not a free safety remedy), but it's the manufacturer acknowledging the issue and how to fix it.
TECHNICAL SERVICE BULLETIN: INFOTAINMENT SOFTWARE UPDATE PROCEDURE - This bulletin provides information on the process for downloading infotainment software updates and preparing USB for installation on applicable Kia vehicles. The software downloads and USB preparation process is similar across all supported platforms; however, in‑vehicle installation procedures vary by head unit type.

The failure pattern owners describe
The 2024 Sportage shows widespread electrical faults that have eluded dealer diagnosis despite multiple service visits. The most critical complaint is an instrument cluster that blacks out randomly during driving, erasing speedometer and gauge display for up to 5 seconds while the screen reboots—a federal visibility violation. This happens at any speed, even while parked, and one owner logged occurrences over two years without resolution. Dealers have replaced the cluster, infotainment screen, and performed software updates without fixing it; one tech discovered a re-welded coaxial cable that was never properly documented.
Owners also report sudden unintended acceleration that overpowers the brake pedal, engine stalling on highways and at traffic lights with all warning lights illuminating simultaneously, and intermittent door lock failure requiring the mobile app as a workaround. Several owners describe their vehicles becoming unresponsive to restart for minutes after stalling. All dashboard warning lights cycling on and off repeatedly during long drives is a common complaint. One owner couldn't shift out of park when all lights illuminated. Kia's corporate response has been inconsistent—some dealers were told the issue is a coaxial wiring problem, while one owner was simply told to get a new car. Most dealers state they cannot replicate the problem and therefore cannot properly diagnose it.

Failure modes owners describe
Instrument cluster/dashboard screen blackout or reboot
The instrument cluster screen goes blank or reboots while driving, eliminating visibility of speedometer, gauges, telltales, and headlights. The screen then lights back up showing a system check message. This can occur at any speed, in any driving condition, and even while parked with the engine running. One owner reports a CAN message error causing the 4.2-inch screen to reboot for approximately 5 seconds, creating a compliance violation under FMVSS 101.
When: Reported starting from purchase (June 2024 for one owner; February 2024 for another). Occurs randomly and repeatedly over months to nearly two years of ownership.
Symptoms owners cite: Instrument cluster screen goes blank during driving; Loss of speedometer and gauge visibility; Headlights shut off; System check message displays; Screen reboots unpredictably at all speeds; Cruise control disengages and reengages when screen reboots; Event occurs while parked with engine on; All dashboard warning lights illuminate during reboot
Codes mentioned: CAN message error (abnormal)
Repairs/costs cited: Dealers have replaced instrument cluster/dashboard screen, infotainment screen, phone charging pad, and performed multiple software updates without resolving the issue. One dealer identified and re-welded a faulty coaxial cable connection that they were initially unaware existed. Most dealers report inability to replicate the problem for proper diagnosis.
Recalls/TSBs owners mention: Kia corporate tech line suggested faulty electrical wiring or coaxial cable issue. One owner reported Kia corporate told them to get a new car rather than repair the defect. Dealers report they cannot recreate the problem and therefore cannot properly diagnose or fix it.
Sudden unintended acceleration
Vehicle accelerates forcefully on its own without driver input while stopped or at low speed. The brake pedal does not prevent or stop the acceleration. Vehicle continues accelerating even after striking objects.
When: April 18, 2026, while pulling into a parking space at low speed. Vehicle was at complete stop with foot on brake.
Symptoms owners cite: Sudden, forceful acceleration without accelerator pedal pressed; Brake pedal unresponsive; Vehicle jumps over parking bumper; Continued acceleration after impact with fixed post; Uncontrolled vehicle behavior
Repairs/costs cited: Vehicle towed to Kia dealership pending inspection. Front-end damage sustained from collision with post.
Engine power loss and stalling
Vehicle loses power during operation and requires engine restart. In one incident, vehicle stalled and stopped on interstate highway, creating a dangerous traffic situation. Another owner reports vehicle dying at a traffic light with all dashboard lights illuminating and refusal to restart for several minutes.
When: Starting approximately 2 months after purchase for one owner. Second interstate incident occurred after several months of power loss cycles. Another incident at traffic light—timing unclear.
Symptoms owners cite: Loss of engine power while driving; Engine shutdown requiring restart; All warning lights illuminate on dashboard; Engine dies at traffic light; Vehicle unresponsive to restart attempt for minutes; Multiple power loss events over months
Repairs/costs cited: Dealers attempted to resolve by replacing infotainment screen. Issue persisted after repair attempt.
Door lock malfunction
Door lock buttons on handles fail to function, preventing doors from locking remotely. Issue is intermittent and resolves spontaneously. Owners must use the mobile app to lock and unlock the vehicle.
When: Random occurrences; one owner reports 4 instances over 2 years of ownership.
Symptoms owners cite: Door lock button on handle does not work; Random, intermittent failure; Requires mobile app to lock/unlock vehicle; Spontaneous resolution after driving
Shift lock malfunction
Vehicle becomes unable to shift out of park despite engine running. Occurs in conjunction with all dashboard warning lights illuminating.
When: Occurred on fourth instance of all dash lights illuminating (specific timing not stated by owner).
Symptoms owners cite: Unable to shift vehicle out of park; All dashboard lights illuminate; Vehicle stuck in park
Dashboard warning lights cycling on and off
All warning lights on dashboard illuminate and extinguish repeatedly, often during long drives. This behavior is unpredictable and occurs from early ownership. In one case, simultaneous illumination of all lights also caused shift lock malfunction.
When: Starting from day one of purchase for one owner; occurs after approximately one hour of driving.
Symptoms owners cite: All warning lights turn on and off together; Lights cycle during long drives; Unpredictable on/off cycling; All lights illuminate simultaneously in some cases; Possible concurrent shift lock failure
Repairs/costs cited: Dealer attempted infotainment screen replacement as suspected cause.
Battery discharge warning problem
Battery discharge warning appears on dashboard after other electrical repairs. One owner reports this warning started after their dealer fixed the infotainment/coaxial cable issue.
When: Emerged after infotainment system repair; no prior history of warning before coaxial cable re-welding.
Symptoms owners cite: Battery discharge warning illuminates; Warning appears after other electrical work completed
Repairs/costs cited: Dealer unable to resolve after infotainment repair.

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…
A month after buying my vehicle in February of 2024, while driving my vehicle the screen behind my steering wheel will black out and come back on and do a system check as if I had just turned my car on. It happens at all times of day, at all speeds. I kept a log of some of the incidences and there are no two that are the same. I have even been in park with the car on and it will happen. When you…
Stopped at traffic light, light turned green and went to accelerate. Car died, all lights came on dash in oncoming traffic and car would not restart for minutes.
