2021 GENESIS G90 Forward Collision Avoidance Automatic Emergency Braking Problems

Driving on interstate at 70mph while it was raining. Signaled and changed lanes. Steering wheel started jerking left and right and the power steering light flickered on and off.

Power steering light was off but the power steering still did not work. I slowly and carefully drove home, which was nearby. About 2 miles into the drive, power steering returned. It felt like it partially returned at first and then fully returned after several minutes.
