The positive battery terminal has a design flaw where it will wholly lose conductivity with the battery post due to vibrations, stress and age. After numerous dealer visits where "nothing was wrong" I began to diagnose the issue myself. I tracked it down to faulty positive battery terminal, which due to the lack of manufacturer availability I had to correct myself. It seems to be such a widespread but "unknown" issue with the entire vehicle model that I made a repair guide on the subject with photos: https://genesisowners.com/genesis-forum/threads/improved-positive-battery-terminal-box.32768/#post-411757 The primary issue at stake is the sudden, unexpected loss of power steering when maneuvering at low speeds. The vehicle will lose additional safety systems when the battery power is interrupted, such as collision avoidance, parking sensors, airbags and even powertrain control in extreme cases. No manufacturer diagnostic codes will ever be set as the systems in the vehicle do not account for sudden unexpected power loss. Problem is aggravated by objects on trunk floor resting on terminal box. The secondary issue is that when a power interruption occurs while the vehicle is in operation, the vehicle will not properly shut down when the ignition is turned off. Rather than unlocking doors and assisting handicapped drivers via the easy exit seat feature, the car completely dies and does not wake back up. Vigorous door slamming or any other large impact to the body of the car will sometimes bring systems back online, by fractionally moving the positive battery terminal. If systems do not return, the driver is unable to lock the doors or open the trunk. Hyundai does not make the positive terminal a replaceable item, rather, it's only sold as a combined part with a $1400 battery cable (plus 8 hours labor). Dealers and owners alike are averse to replace this part for such a high price, when the battery terminal itself is worth less than $20.
