5 Blind Spot Detection problem

Failure Date: 08/17/2021

On August 17, my new Elantra lost power steering, and most safety related features. Most all instrument warning lights came on. Was able to get car to dealer service where they kept car overnight, and reset the error lights. They told me, they recorded the computer codes, but could not find the cause of the problem. On August 26, again the instrument warning lights suddenly came on again. Took car to dealer service, where they kept car almost 2 weeks, but could not find the cause. They recorded computer codes. I contacted Hyundai, and a case number was established, but no fix has been found. Case worker has been difficult to reach. My wife refuses to drive this car. New electrical problems: 1. Driver's door handle light not working at night when approaching door. 2. Receiving false emails that car doors are not locked, but they are locked. 3. Using myhundai, shows door are not locked, but they are. When using application to lock doors, false message back that a door is open. 4. Navigation cuts off intermittently. 6. Gasoline consumption computer resets sometimes, other times it does not. 7. Remote start application does not work, says my door is open. 8. Items missing from center display menus. (door light, reset gas mileage etc) car has to go back to dealer service for needed repairs.
