The wiring for the air bag system under the driver's seat is exposed and unprotected which has led to disconnection and or damage to the wiring harness which then results in a disabled air bag system. This is a manufacturer design flaw and a serious safety issue. Other owners who have experienced damage to their wiring harness here have had disabled air bag systems for prolonged periods and costly repairs that Hyundai had refused to cover under warranty despite the fact that it is an obvious design flaw and a serious safety issue. See attached photos for evidence of how exposed this wiring harness is and suscebtible to damage as well as an example of damage which can occur which other owners have reported. Damage to this unit due to poor design results in compromised driver and passenger safety and extremely costly repairs ($10,000) which it appears Hyundai is refusing to cover under warranty. We request that this be recalled in order replace the design so this wiring harness is protected properly.

My BRAND NEW car is suffering an ICCU issue. I first noticed the screens going completely black while driving. I then noticed that I can’t charge at all on Lvl 1 and Lvl2 chargers (AC), but I went to the dealership and the helped me charge on lvl 3 DC fast charging. This is an incredibly dangerous problem, if this results in my 12V battery dying, I could be stranded while driving.
