On the 2023-2025 Hyundai Ioniq 6, like the Ioniq 5, the Ioniq 6 shares the E-GMP platform's 12V auxiliary battery drain issue. Always-on telematics, Bluelink, and various modules draw down the 12V battery when the vehicle sits for extended periods. The issue is worse in cold weather when battery capacity is reduced.
Install the latest software update (OTA or dealer). Keep the vehicle plugged in during extended parking. If the 12V battery has been deeply discharged, replace it with a quality AGM Group 47 battery ($200-300). Disable unnecessary Bluelink features. Hyundai's software update improves the DC-DC converter's 12V charging algorithm.

On the 2023-2025 Hyundai Ioniq 6, despite the Ioniq 6's aerodynamic design for low wind noise, many owners report excessive road and tire noise, especially on rough or coarse pavement. The heavy battery pack transmits road vibrations through the floor, and the wheel well insulation is insufficient. The EV's silent drivetrain makes road noise the dominant cabin sound.
Switching to a quieter tire such as the Michelin e.Primacy or Continental EcoContact 6 can reduce noise by 3-5 dB. Adding sound-deadening material (Dynamat or equivalent) to the wheel wells and floor costs $200-500 DIY. Factory floor mats with additional insulation help slightly. There is no factory fix from Hyundai.

On the 2023-2025 Hyundai Ioniq 6, the Ioniq 6's streamlined design creates noticeable wind noise intrusion, particularly around the frameless door windows and side mirrors at highway speeds. The door seal design does not fully prevent wind noise, and the low-drag side mirrors create turbulence at the A-pillar. The EV's silent drivetrain makes wind noise more noticeable.
Apply adhesive weatherstripping to the door frame to improve seal (3M Automotive Weatherstrip, $15-25). Adjusting door striker alignment can improve seal at the top of the window. Wind deflector strips on the side mirror base reduce turbulence ($30-50). Dealer door adjustment is typically covered under warranty.

On the 2023-2025 Hyundai Ioniq 6, the Ioniq 6's sloped rear design causes the rearview camera and parking sensors to be easily obstructed by water, snow, mud, and road spray. The camera sits in a recessed area that collects debris, and the aerodynamic shape channels road spray directly onto the sensors. This reduces safety system reliability in adverse weather.
Apply a hydrophobic coating (Rain-X or similar) to the rear camera lens to shed water. Clean the camera and sensors regularly in bad weather. Some owners have installed a small camera shield/visor to deflect spray. Hyundai has not issued a formal fix. Camera cleaning costs nothing; aftermarket camera shields are $20-40.
