Software Bugs Affecting Core Vehicle Functions
As a first-model-year vehicle with extensive software-defined features, the 2024 EV9 is affected by numerous software bugs. Owners report the digital instrument cluster displaying incorrect speed or range data, ADAS features activating inappropriately, the Highway Driving Pilot (Level 3 autonomy in some markets) producing false alerts, and scheduled charging failing to initiate at the programmed time.
Kia has released multiple OTA software updates to address these issues. Ensure the vehicle is connected to Wi-Fi and updated to the latest firmware version. For critical ADAS-related software bugs, the dealer may need to perform the update using the diagnostic tool. Kia has committed to monthly software improvement releases for the first year.
Est. Cost: $0 for software updates under warrantyAir Suspension Leveling Issues (GT-Line)
The optional electronically controlled air suspension on GT-Line trim can exhibit uneven ride height, with the vehicle sitting lower on one corner after parking. Some owners report the suspension failing to adjust between comfort and sport settings, and the auto-leveling function may not compensate correctly for heavy cargo loads. Warning messages about suspension malfunction appear on the instrument cluster.
Have the dealer perform a suspension calibration reset using the diagnostic tool. If a specific air strut is not holding pressure, it will need replacement. The air compressor and ride height sensors should also be inspected for proper operation. The air suspension is covered under the basic warranty.
Est. Cost: $0 under warranty; $1,500 - $3,000 per air strut; $800 - $1,500 for compressor out of warrantyInfotainment Triple-Screen Display Issues
The EV9's signature triple-screen display panel (two 12.3-inch screens and one 5-inch screen) can experience synchronization issues where the screens display conflicting information, one screen goes black while others remain active, or touch input registers on the wrong screen. The panoramic curved display design also makes glare management difficult in bright sunlight.
Kia has released infotainment software updates to improve screen synchronization and touch input accuracy. Have the dealer update the head unit and instrument cluster firmware. If a physical display panel has failed, the entire triple-screen assembly may need replacement as an integrated unit.
Est. Cost: $0 for software update; $2,000 - $4,000 for display assembly replacement under warrantyThird-Row Seat Access and Power Fold Malfunction
The power-folding second-row seats, designed to provide access to the third row, can malfunction and fail to fold or return to position when commanded. The seat track motor may make grinding noises, and the one-touch fold mechanism may stop mid-travel. This is particularly problematic given the EV9's role as a three-row family SUV.
Have the dealer inspect the second-row seat track motors and fold mechanism for obstructions or motor failure. The seat ECU software may need updating to resolve the one-touch fold sequencing issue. If the seat track motor has failed, it will need replacement under warranty.
Est. Cost: $0 under warranty; $400 - $900 for seat motor replacement out of warrantyDC Fast Charging Speed Below Expectations
Despite Kia's advertised 10-80% charging time of approximately 24 minutes under ideal conditions, many EV9 owners report real-world DC fast charging speeds significantly below this figure. The charging curve drops off sharply above 60% SOC, and cold weather performance is particularly disappointing, with some owners reporting charge times exceeding 50 minutes for 10-80%.
Use the built-in navigation to route to the charger for automatic battery preconditioning. Kia has released OTA updates to optimize the charging curve and improve cold-weather preconditioning. Charging at an 800V-capable station (such as Electrify America 350kW units) is required to achieve peak charging speeds. Ensure the vehicle software is fully updated.
