P0705 on Genesis by model: symptoms, diagnosis and fix
Blanking pins were incorrectly installed in the transmission control harness connectors at the supplier, allowing water to enter the connectors and cause an electrical short. The short can make the transmission controls erroneously and unexpectedly shift from Park to Neutral, allowing the vehicle to roll away if the parking brake is not set. Genesis recall 020G (NHTSA 24V-205) covers roughly 15,645 GV70 built May 10, 2023 to Feb 25, 2024.
Common Symptoms
- Vehicle unexpectedly shifts from Park to Neutral
- Vehicle rolls when parked without the parking brake set
- Transmission warning messages
- Intermittent shift-by-wire faults after rain or car washes
How to Fix
Check the VIN against NHTSA recall 24V-205 (Genesis 020G). Dealers inspect the transmission control harness and repair the connector or replace the harness and internal wiring as necessary, free of charge. Until repaired, always set the emergency/parking brake and turn the ignition off when parked.

On Genesis it is documented across 1 model: GV70.
