2022 Hyundai Elantra electrical system problems

I drove my vehicle to the store, parked and went in to the store to get some things. When I came out and started the car several things were wrong with the car. The power steering was not working, the RPM gauge didn't work at all, the back up camera also was not operational. The check engine light was on, the forward collision light was illuminated. I was able to drive it home but that was a sketchy drive home.

The contact owns a 2022 Hyundai Elantra. The contact stated that when his son started the vehicle, the instrument panel failed to illuminate. Additionally, while driving approximately 10 MPH, the failure persisted. The vehicle was towed to the dealer where it was diagnosed and determined that the battery needed to be replaced. The battery was replaced, and the vehicle was repaired. The contact tested the battery with a voltage reader the voltage and the voltage had gone from 12.8V to 12.4V within five days.
