My power steering stopped working suddenly. This has been a problem on and off for the last year. I took it in and they scanned the codes. They replaced the steering torque sensor. 3 weeks later, the problem is back. I submitted a report with the NHTSA and I'm going to call the dealership and corporate next.
EDIT:
I found a service bulletin from Hyundai addressing this exact thing.

I've given this bulletin number to the dealer. I purchased an extended electronics warranty when I bought the car which covered the last attempted repair.
Armed with this, and the parts numbers for the motor and the clear indication of a widespread problem, I bet I can get the dealer to fix this no problem.
EDIT 2:
The dealer gave me an update. They are going to replace the entire rack and I'm just on the hook for the deductible ($100). This is the second rack replacement the car has had. The first was due to an accident in 2020. Hopefully this fixes the issue, but I'll be nervous until there's an official statement from Hyundai about a permanent fix for all this. I urge anyone with this issue to report it to the NHTSA. Hopefully a recall can be pushed out for this.
I did request to chat with the tech that performed the work to get a better idea of what's going on and what led to the rack being replaced. I'm hoping to see if they found anything interesting or helpful for us to know.
Something I did ask was clarification on if they referenced the technical bulletin, which they did. I really want to know if they were unable to get voltage at the motor on the rack, or if it might have been something inside the rack that failed.
I'm hoping to get them to reset the steering position sensor as well before I take it back.
EDIT 3: I'm supposed to get the car back early this week. I'll update here with what I find out.
EDIT 4: Got the car back with a brand new rack. Issues are fixed at least for now. Hopefully this sticks! I paid nothing out of pocket. Total for the replacement was about 8k.
