2016 model year · 155+ owner reports · Updated April 2026
According to Au7o's analysis of 155+ owner reports, the 2016 Kia K900 has 5 documented known issues, with 1 rated critical. The most serious is Rear Electronic Air Suspension Leak and Compressor Failure ($1,000-$3,500 repair). Across all issues, repair costs range from $0 to $3,500. DIY maintenance guides at au7o.io.
On the 2015-2020 Kia K900, the K900 flagship sedan uses rear electronic air suspension for its luxury ride. The air springs develop leaks at the rubber bladder and crimped fitting areas after 4-6 years. The compressor overworks to compensate for leaks and eventually burns out. The K900's limited production volume means replacement parts are expensive and sometimes back-ordered. The vehicle sags at the rear when parked, with the compressor running audibly from the trunk area.
Replace both rear air springs together and the compressor if it has been running excessively. Arnott and Continental (OEM supplier) make replacement air springs. An air suspension conversion to coil springs is possible but no dedicated kit exists for the K900 due to low production volume — a custom setup using compatible strut dimensions is required.

On the 2015-2017 Kia K900, the first-generation K900 (2015-2017) infotainment system suffers from frequent freezing, slow response, and random reboots. The head unit's processing power is inadequate for the system's demands, and the software develops memory leaks over time. The screen may freeze on a particular screen, go black, or reboot mid-navigation. Climate controls that are integrated into the touchscreen become inaccessible during freezes. Kia released software updates but the underlying hardware limitations remain.
Visit the Kia dealer for the latest infotainment software update. A hard reset (hold power button for 10 seconds) temporarily resolves freezes. If software updates don't help, the head unit may need replacement. Some owners install aftermarket Android Auto/CarPlay head units, though this requires custom wiring for the K900-specific steering wheel controls and climate integration.

On the 2015-2020 Kia K900, individual LED elements in the DRL strip fail, creating a partially lit or flickering appearance. The LED modules are integrated into the headlight assembly, making individual LED repair impractical.
Replace headlight assembly containing the failed LED DRL module. Aftermarket LED driver boards are available for 2015-2018 models as a repair alternative. Check for water intrusion in headlight housing which accelerates failure.

On the 2015-2017 Kia K900 5.0L Tau GDI V8, the 5.0L Tau GDI V8 in the first-generation K900 can develop timing chain tensioner rattle on cold start and GDI fuel injector failures. The hydraulic tensioners bleed down overnight, causing chain slack and rattle for 1-5 seconds at startup. The GDI piezoelectric fuel injectors can develop carbon deposits on the tips that cause uneven spray patterns, misfires, and rough idle. The combination of timing chain noise and injector-related misfires can be alarming on a luxury flagship vehicle.
For timing chain rattle, change oil every 5,000 miles with 5W-30 full synthetic (Mobil 1, Pennzoil Platinum). If rattle persists beyond 5 seconds, replace timing chain tensioners. For injector issues, use a GDI-specific fuel system cleaner (Liqui Moly GDI Cleaner) every 10,000 miles. Severely coked injectors require removal and ultrasonic cleaning ($50/injector) or replacement ($150-250 each).

On the 2015-2020 Kia K900, the 8-speed automatic transmission produces a noticeably harsh 2-3 upshift during gentle acceleration. The torque converter lockup strategy and shift calibration contribute to the harsh engagement. TSB available for transmission software reflash.
Have dealer perform transmission control module software update (TSB). Drain and refill transmission with Kia SP-IV RR ATF. If harshness persists after reflash, valve body replacement may be necessary.
