Vehicle Specs & Maintenance Data
The 2016 Kia K900 maintenance specs on this page cover the key fluids, torque values, and wear items you need for routine service. Use these numbers as a quick reference when performing oil changes, tire rotations, brake jobs, and other scheduled maintenance on your Kia K900.
For oil changes, the 2016 Kia K900 takes 5W-20 Full Synthetic motor oil with a capacity of 8 quarts. Brake fluid type is DOT 3, the recommended coolant is Phosphate-based Green/Blue, and transmission fluid is SP-IV-M (ATF). Always use the manufacturer-recommended fluids to maintain warranty coverage and engine longevity.
When mounting wheels on the Kia K900, torque the lug nuts to 80 ft-lbs using a calibrated torque wrench. Over- or under-torquing can lead to warped brake rotors or loose wheels. Re-torque after 50 to 100 miles on newly installed wheels.

Common problems reported by 2016 Kia K900 owners, with recommended fixes and estimated repair costs.
Air Suspension Failure and Compressor Wear
The 2016 K900's electronically controlled air suspension is the most problematic system on the vehicle. The air struts can develop leaks causing the vehicle to sag on one or more corners after parking, and the air compressor runs excessively to compensate, eventually burning out. Ride height sensors can also fail, causing the system to set the vehicle at an incorrect height.
Diagnose which air strut is leaking by checking for hissing sounds and monitoring which corner sags. Replace the leaking air strut and inspect the compressor for overheating damage. If the compressor relay or motor has failed, replace the entire compressor assembly. Some owners convert to conventional coil springs for long-term reliability.
Est. Cost: $1,500 - $3,000 per air strut; $800 - $1,500 for compressor; $200 - $400 per ride height sensorInfotainment System Lag and Crashes
The 2016 K900's infotainment system suffers from significant performance issues including slow touchscreen response, extended boot-up times (sometimes over 30 seconds), and complete system crashes that require a reboot. The navigation system may also display outdated map data and fail to calculate routes correctly.
Have the dealer update the infotainment firmware to the latest available version. Map updates can be downloaded from Kia's navigation update portal. If the system remains sluggish after software updates, the head unit's internal storage may be failing and the entire unit will need replacement.
Est. Cost: $0 for software update; $100 - $200 for map update; $800 - $2,000 for head unit replacementElectrical System — Battery Drain and Module Faults
The K900's luxury-level electrical system with numerous control modules is prone to parasitic battery drain and intermittent module communication faults. Owners report dead batteries after a few days of sitting, random warning messages on the dashboard, and various convenience features (power seats, memory mirrors, smart trunk) failing intermittently.
Have the dealer perform a parasitic draw test and scan all modules for fault codes. Common culprits include the telematics module, the smart trunk controller, and the rear entertainment system failing to enter sleep mode. Software updates for the affected modules can reduce draw. Replace the battery with a high-capacity AGM unit if it has been deeply discharged.
Est. Cost: $150 - $400 for diagnosis; $200 - $600 for module repair or replacement; $200 - $400 for batteryRear Seat Entertainment System Failure
The rear seat entertainment system with dual LCD screens is prone to failure, with screens going black, displaying distorted images, or losing HDMI input functionality. The wireless headphones may also lose audio sync or fail to pair. Given the K900's positioning as a luxury vehicle, this is a significant feature loss.
Have the dealer check the wiring harness connections to the rear screens and the entertainment control module. Software updates may resolve input detection issues. If a screen has failed, the individual display unit can be replaced. Replacement wireless headphones can be ordered through the Kia parts department.
Est. Cost: $300 - $800 per rear screen replacement; $100 - $200 for headphone replacementHeated and Ventilated Seat Malfunction
The heated and ventilated seats on the 2016 K900 can malfunction, with common issues including the seat heaters failing to reach adequate temperature, the seat ventilation fans running at reduced speed or not at all, and the rear heated seats cutting out intermittently. The seat control module or the heating/cooling elements themselves may be at fault.
Have the dealer diagnose the seat control module for fault codes. If the heating element has failed, the seat cover may need to be removed to replace the heating pad. For ventilation fans, the blower motor assembly under the seat cushion can be replaced. Check the seat wiring harness connectors for corrosion.
Est. Cost: $200 - $500 for heating element; $300 - $600 for ventilation motor; $100 - $200 for control module reprogram
