This car started to show engine problems, when trying to drive the car begins to shake a lot and loud noises and a light showing an engine malfunction pops up. We have contacted hyundai/genesis about this. They said it was a software issue and needed an update.seems like problem go away. Next day , the exact same problems still exist. It feels unsafe to drive the this vehicle as I am worried what if the engine fully breaks down mid drive or somewhere parked leaving me stranded
