I am reporting a severe vehicle safety hazard involving a sudden loss of motive power and extreme thermal failure on my 2012 Hyundai Equus Signature 5.0L. In July 2022, at 88,845 miles, an authorized Hyundai dealership replaced the transmission under a factory warranty event.

The steering rack malfunctions or fails. When driving at high speeds, the steering wheel gets stuck after being turned. It does not return to center and has to be yanked or forced back to center.

The issue has been confirmed by numerous reports and…

Passenger side seat's active headrest auto deployed/broke when I was driving the car alone. This might be safety issue if driver seat headrest also breaks while driving.

For the last year or so when driving my Equus the signal lights left or right side has been working intermittently. I can go months without any issues but lately it seems to be worsening. I transport my Mom that has dementia around and its scary because it seems never know when the lights may not work at all.
