2025 Hyundai Tucson Radiator Core Support: Collision Damage, Inspection, and Replacement

Symptoms of a Damaged Radiator Core Support

Unlike parts that wear out over time, a radiator core support typically only fails due to physical impact from a front-end collision. The symptoms are almost always visual and structural.

• Visible Damage: The most obvious sign is a bent, cracked, or broken support frame. This can often be seen by looking down into the engine bay from above the grille. The support may be made of steel, aluminum, or composite plastic, all of which will show clear signs of stress or fracture after an impact.
• Misaligned Body Panels: If the hood does not close properly, or if the gaps between the fenders, hood, and bumper are uneven, it's a strong indication the underlying support structure is bent. The radiator support is what dictates the alignment of these panels.
• Hood Latch Problems: A hood that is difficult to latch or release often points to a misaligned hood latch, which is typically mounted directly to the radiator support.
• Headlight Aim Issues: If the headlights seem to point in different directions or sit unevenly, it could be because their mounting points on the core support have been compromised.
• Cooling System Problems: While not a direct symptom of the support itself, if the support is damaged, it's highly likely the radiator or A/C condenser mounted to it is also damaged. This can lead to coolant leaks (puddles of green, pink, or orange fluid under the car), engine overheating, or a non-functional air conditioning system.
• Unusual Noises: A rattling or clunking sound from the front of the vehicle could indicate a loose or broken support, allowing the radiator and other components to vibrate excessively.

Buying a Used 2025 Hyundai Tucson Radiator Core Support

For a vehicle as new as the 2025 Tucson, any available used radiator support will have come from a very low-mileage vehicle that was in a collision. This makes careful inspection critical.

Inspection Checklist:

• Check for Cracks and Bends: Carefully inspect the entire part, especially around mounting holes and corners. For plastic or composite supports, look for hairline cracks. For steel or aluminum, check for kinks, bends, or stress marks. A bent support will not allow for proper panel alignment.
• Verify All Mounting Points are Intact: The support has numerous mounting points for the radiator, fans, headlights, and bumper. Compare the used part to photos of a new OEM part (part number 64101-CW500) to ensure every tab, bracket, and mounting hole is present and undamaged.
• Look for Signs of Previous Repair: Be wary of supports that show signs of repair. Look for non-factory welds, body filler, or fresh paint in isolated spots, which could be hiding previous damage. A repaired support may not have the same structural integrity as an original part.
• Inspect Associated Components: Used radiator supports for the 2025 Tucson are often sold as a complete front-end module, including the radiator, condenser, and fans. Inspect these components for damage like bent fins, corrosion, or leaks at the seams. Even if the support looks good, a damaged radiator adds significant cost.
• Confirm Build Location: Parts diagrams for the Tucson sometimes specify 'US built' or 'Korea built'. While the main support may be the same, attached brackets could differ. Whenever possible, match the part to your vehicle's specific build.

Known Issues, Recalls, and TSBs for the 2025 Hyundai Tucson

As of mid-2026, there are no recalls or technical service bulletins (TSBs) specifically for the radiator core support on the 2025 Hyundai Tucson. However, several important safety recalls and one TSB have been issued for this model year that owners and buyers should be aware of.

Safety Recalls (NHTSA)

• Recall No. 281 (NHTSA ID 25V-549): Engine Connecting Rods. Certain 2025-2026 Tucson vehicles may have improperly tightened engine connecting rod bolts. This can lead to abnormal engine noise, loss of power, engine damage, and a potential oil leak, which increases the risk of a fire. The remedy is a complete engine replacement, performed by a dealer at no charge.
• Recall No. 289: Side Curtain Airbags. On some 2025 Tucson vehicles, the side curtain airbags may not have been installed correctly, which could prevent them from deploying as intended in a crash, increasing injury risk. Dealers will reinstall the airbags free of charge.
• Recall No. 304: Instrument Panel Software. A software error can cause the instrument panel display to go blank intermittently, hiding critical information like the speedometer. This affects over 96,000 2025-2026 Tucson models. Dealers will perform a software update to correct the issue.
• Glove Box Air Bag Warning Label: Some 2025 Tucson vehicles may be missing the required airbag warning label in the glove box, a compliance issue.

Technical Service Bulletins (TSBs)

• TSB 25-01-023H: EGR Valve Assembly and Gasket Replacement. This service campaign addresses an issue where the EGR valve sensor may have been contaminated during manufacturing, potentially causing an electrical short. This applies to certain 2025 Tucson models.

Cost Comparison

Prices can vary based on location and supplier. The 2025 model is too new for a wide range of aftermarket or remanufactured options.
