I read the article at 30.Dec. 2019 which claims that Hyundai/Kia cars will be recalled because of their own flaws. 

The exact quantity of recalled cars is 642,272.

By the car models : Hyundai Grand Starex(TQ) -130,140 units, Porter2(HR) – 295,982 units, Hyundai Solati – 3,312 units, Mighty Narrow  – 3,922 units.
Hyundai say that they found the error on setting time of  position information delivery on air intake control valve. This error can cause instability of RPM so cars may be turned off during driving because of it. So they decided to recall those 6 models.
