Is there a fix? Manufacturer service bulletins
The manufacturer has issued service bulletins covering engine on this vehicle — documented repair instructions, service campaigns, or warranty extensions sent to dealers. A TSB isn't a recall (it's not a free safety remedy), but it's the manufacturer acknowledging the issue and how to fix it.
This TSB references the Op codes to use for claim submission and the Parts required based on the vehicle’s inspection results from TSB 22-01-023H (DTC P1326 – Engine Bearing Inspection/Engine Replacement) or the latest version.

full bulletin at NHTSA ↗Hyundai is conducting a campaign to enhance the knock sensor software to detect abnormal engine bearing noise before potentially severe engine damage occurs. If abnormal engine bearing noise is detected, the Malfunction Indicator Lamp (MIL) will blink continuously, and the vehicle will be placed in Engine Protection Mode allowing the customer to drive to the nearest Hyundai dealer for diagnosis and repair. In addition, DTC P132600 will be recorded in the ECM. The vehicle can continue to be operated for a limited time in Engine Protection Mode, but it will accelerate slower and have a reduced maximum speed. Engine RPMs will be limited to approximately 1800-2000 RPM.

Accelerating the vehicle to get to highway speeds, vehicle pulls hard and bogs down into limp mode, resulting in a p0234 MIL. Vehicle is at the dealership but haven't heard from them about it.
