The screen display will freeze and give an error message. this is dangerous and distracting while operating the vehicle because after the freeze the screen will go black for a period of time, then the system will boot with the "welcome" screen, then it will ask you to agree with the terms which requires a manual driver operation. this has happened multiple times at random intervals.
There is a flaw in night driving where the illuminated instrument cluster reflects on the front windshield glass in the driver's line of vision creating a distracting hazard. the only way to alleviate this condition is to completely dim the instrument cluster to a setting of one which makes the cluster too dim to read. so you have a choice: stare at a reflection in your windshield or be unable to see your speedometer.
In december, 2015, my 6 month old 2015 kia k900 with no more than 8,000 miles refused to start. two and half hours later, with two tow trucks on the scene, aided by kia roadside assistance, the car finally re-started. less than a month later on sunday, january 3rd, 2016 i left the driveway heading west, and about 4 houses down at approx. 25 miles per hour the vehicle began to 'shut down.' there was loud screeching sound, the steering wheel shook, and all the electronics went dead. the vehicle was inoperable, as the steering, gauge cluster, electronics all shut down. the electronic brake engaged or the car went into park, i'm not even sure, but the car came to a sudden stop in the middle of the road throwing two of us forward with the safety restraints engaging. kia roadside came out again and after a while, they started the car again, but there were no electronics. i returned the car home. a tow truck driver arrived and tried to start the car and it 'hard' started, with no electronics. kia's had my car since january. kia has driven the car over 400 miles, found "no codes" but, did replicate the problem. i've lost all faith in the car and i believe it is a danger to the public.
