On the 2017-2022 Kia Sportage, sportage SUVs equipped with the genuine Kia tow hitch harness can suffer an electrical short in the harness module's printed circuit board. Chloride contamination and foreign material/moisture introduced during manufacturing corrode the PCB, which can short and ignite even with the vehicle parked and off. Kia documented 3 confirmed fires and roughly 30 'localized melting' incidents across the recall population (~70,887 Sportage and Sorento units). This is distinct from the 2012-2016 HECU/ABS module fire — the failure is in the trailer-wiring control module, not the brake hydraulic unit.
Have the vehicle checked against recall SC249 (NHTSA 22V-703) by VIN. The interim remedy was to remove the tow hitch harness fuse; the final remedy replaces the harness/module. Owners were advised to park outside and away from structures until repaired. Repair is free under recall.
On the 2020-2025 Kia Sportage, the infotainment head unit in 2020+ Sportages enters a continuous reboot loop or freezes on the splash screen, leaving the driver without navigation, backup camera, and climate controls (on models with touchscreen-only HVAC). The issue is caused by software bugs and insufficient system memory for the connected services. Firmware updates from Kia have improved but not fully resolved the issue. The problem often occurs after USB device connection or Bluetooth pairing.
Bluetooth disconnecting and reconnecting repeatedly
Climate controls unresponsive on touchscreen
Apple CarPlay/Android Auto crashing
How to Fix
Perform a hard reset by pressing and holding the power/volume knob for 10 seconds. If the reboot loop persists, disconnect the vehicle battery for 30 minutes to fully reset the head unit. Visit a Kia dealer for the latest infotainment software update (free under warranty). If the issue continues after the latest firmware, the head unit may need hardware replacement. Avoid connecting USB drives with large music libraries (1000+ songs) which overwhelm the system.
On the 2017-2023 Kia Sportage, aWD-equipped Sportages develop a humming, growling, or grinding noise from the rear differential coupling unit. The electronically-controlled clutch pack coupling wears internally, and the coupling fluid degrades from heat. The noise increases during turns and low-speed maneuvering. If ignored, the coupling can fail completely, leaving the vehicle in front-wheel-drive only mode.
Clunking from rear when shifting from reverse to drive
How to Fix
Drain and refill the rear differential coupling fluid with Kia-specified coupling fluid (not standard gear oil). If noise persists after fluid change, the coupling unit requires replacement. The coupling unit is separate from the rear differential and can be replaced independently. Perform a coupling relearn procedure with the Kia Diagnostic System after replacement. Change coupling fluid every 30,000 miles as preventive maintenance.
On the 2017-2022 Kia Sportage, aWD Sportage models (4th generation 2017-2022) develop worn rear differential mount bushings that cause a clunking noise from the rear when accelerating from a stop or transitioning between acceleration and deceleration. The rubber bushings deteriorate and allow excessive differential movement. This is particularly noticeable in cold weather and with higher mileage (60,000+ miles).
Common Symptoms
Clunk from rear when accelerating from stop
Thud noise during acceleration/deceleration transitions
Vibration felt through floor at highway speeds
Noise worse in cold weather
How to Fix
Replace rear differential mount bushings (Kia part #55277-D9000). Some owners upgrade to polyurethane bushings for longer life. Labor involves lowering the rear subframe and is approximately 2-3 hours at a shop. DIY-friendly with a lift and basic tools.

On the 2017-2025 Kia Sportage 1.6T, the 1.6L turbocharged engine in the Sportage develops oil leaks from the turbocharger oil feed line and its banjo bolt connection. The high heat environment around the turbo causes the oil line seals and crush washers to harden and leak. Oil drips onto the hot exhaust manifold and turbo housing, creating smoke and a burning oil smell. If the oil feed line is significantly restricted by carbon buildup, the turbo bearings can be starved of oil and fail.
Replace the turbo oil feed line, banjo bolts, and copper crush washers. Clean any carbon buildup from the banjo bolt oil passages. Inspect the turbo for bearing play — if there is any shaft play or the compressor wheel contacts the housing, the turbo must be replaced. Use OEM Kia crush washers (they are copper and must be new each time). Check oil drain line for restrictions as well.
On the 2017-2025 Kia Sportage, the panoramic sunroof glass on 2017+ Sportages can crack or shatter spontaneously without any impact. The tempered glass panel develops stress fractures from thermal expansion/contraction, especially during rapid temperature changes (hot sun then cold rain, or cold night then morning defrost). When the glass fails, it shatters into small pieces that fall into the cabin. Multiple NHTSA complaints have been filed for this issue.
Replace the panoramic sunroof glass panel. This must be done at a dealer or specialty glass shop due to the large panel size and sealing requirements. After replacement, ensure all four drain tubes are clear and properly connected. Some owners choose to apply a clear security film to the interior surface of the replacement glass to contain fragments if it shatters again. Check if Kia has a warranty extension or goodwill program for this issue.
On the 2017-2022 Kia Sportage, the A6MF-family 6-speed automatic can develop harsh or erratic shifting, hard 6-to-4 kickdown 'bang,' shift flares, brief neutral feel during up/downshifts, and torque-converter clutch (TCC) shudder. The root cause is wear of the reducing-valve bores in the valve body, which lets line pressure drift out of spec; neglected fluid (SP4-spec) accelerates the wear. A documented secondary fault is a valve-body bolt that can abrade the internal wiring harness, producing intermittent solenoid faults. This is a distinct transmission failure mode from the AWD rear-differential coupling noise already documented.
Start with a proper SP4-spec fluid service and a TCM software update if available. Persistent harsh shifting, gear-ratio or solenoid-performance codes are usually resolved by rebuilding or replacing the valve body (with the reducing valves/solenoids), and inspecting the internal harness for abrasion. In severe slip/shudder cases the torque converter is replaced.
