2023-2025 Genesis GV60 Radiator Core Support: A Collision Repair and ADAS Guide

Symptoms of a Damaged Radiator Core Support

Because the radiator core support is a structural component, failure is almost always the result of a front-end collision. Damage is typically visible and affects the alignment of surrounding parts. There are no specific OBD codes for the support itself, but damage can trigger fault codes for sensors mounted to it.

• Poor Panel Alignment: The most common symptom is a visible misalignment of the front bumper, fenders, or hood. The gaps between these panels may be uneven, or they may sit higher or lower than they should.
• Hood Latch Problems: If the core support is bent or shifted, the hood may be difficult to open or close, or it may not latch securely.
• Headlight Aim Issues: Headlights that point too high, too low, or to the side after a minor impact can indicate that their mounting points on the core support have been compromised.
• Battery Cooling System Overheating: Since the support holds the battery's cooling heat exchanger, significant damage can push it into other components, restrict airflow, or cause the cooling fans to bind. This can lead to reduced charging speed or warnings about the high-voltage battery temperature.
• ADAS and Parking Sensor Faults: The GV60 has forward-facing radar and ultrasonic parking sensors mounted in the front fascia area. Damage to the core support can knock these sensors out of alignment, causing warning lights on the dash and disabling features like Smart Cruise Control, Forward Collision-Avoidance Assist, and parking distance warnings.
• Unusual Noises: A rattling or clunking sound from the front of the vehicle, especially over bumps, can be caused by a cracked or loosened core support allowing the cooling module or other parts to vibrate.

Known Issues, TSBs, and Recalls for the 2023-2025 Genesis GV60

As of this writing, there are no recalls or widespread Technical Service Bulletins (TSBs) directly related to a manufacturing defect of the radiator core support itself. However, several recalls and TSBs exist for the 2023-2025 GV60 that are relevant to the front of the vehicle and its systems.

• Recall 25V624000: Affects 2023-2025 GV60 models for a stainless-steel upper windshield molding that may detach while driving. While not part of the core support, it is a notable structural/body issue.
• Recall 25V474000: A software error can cause the instrument panel display to fail, preventing the display of critical information like speed and warning lights.
• ICCU Recall: Certain 2023-2025 models are part of a recall for the Integrated Charging Control Unit (ICCU), which can fail and stop charging the 12-volt battery, potentially leading to a loss of drive power.
• TSB 25-EV-003G: Addresses missing DC insulation caps on the charge port that could lead to damage.
• TSB for Seat Track Play: A TSB was issued to fix minor play in the front seats during acceleration or braking on 2023 models.

Buying a Used Radiator Core Support

Purchasing a used OEM radiator core support is an excellent way to save money on a collision repair, as the part itself is primarily structural. An undamaged, recycled OEM part will fit perfectly and maintain the vehicle's original structural integrity, unlike some new aftermarket parts which can have poor fitment.

Inspection Checklist:

• Verify the Part Number: Ensure the part is OEM number 64101-CU000. This part is specific to the all-electric GV60 platform.
• Check for Cracks and Fractures: Carefully inspect the entire part, paying close attention to corners, mounting tabs for headlights, and the areas where the main frame rails attach. Modern core supports are often made of a composite plastic or stamped steel; look for any stress marks or hairline cracks.
• Confirm Straightness: Lay the support on a flat, level surface. It should sit flush with no wobbling or twisting. Any warping indicates it was removed from a vehicle with significant structural damage and should not be used.
• Inspect All Mounting Points: Check every tab, hole, and clip receiver. Ensure none are broken, stripped, or elongated. Damaged mounting points will prevent headlights, the bumper, and the cooling module from being installed correctly and securely.
• Look for Signs of Previous Repair: Avoid any core support that shows signs of plastic welding, body filler, or non-factory paint. These are indicators of a previously damaged part that may have hidden weaknesses.

Replacement Overview and Difficulty

Replacing the radiator core support is a complex job that should only be performed by a professional body shop or an experienced technician. It involves dismantling the entire front of the vehicle.

• Difficulty: 5 out of 5 (Professional Level)
• Procedure Involves: Removing the front bumper cover, headlights, front radar sensor, ultrasonic parking sensors, hood latch, and the complete cooling module (heat exchanger, A/C condenser, fans). The system must be properly evacuated and recharged by a certified technician.
• ADAS Calibration Required: After reinstallation, any forward-facing sensors, particularly the front radar for the Smart Cruise Control and Forward Collision-Avoidance systems, MUST be professionally recalibrated. Failure to do so will result in malfunctioning safety features and potential warning lights.

Cost Breakdown

Prices can vary based on location and supplier. Labor costs are high due to the complexity of the job and the need for specialized procedures like A/C service and ADAS calibration.
