2017-2020 Genesis G80 & 2015-2016 Hyundai Genesis Fender: The Interchange Secret
This guide reveals the critical compatibility between the Genesis G80 and its predecessor, the Hyundai Genesis, which is key to finding the right fender.
- The fender is interchangeable between the 2017-2020 Genesis G80 and the 2015-2016 Hyundai Genesis Sedan, greatly expanding used part availability.
- This part fits the 4-door sedan ONLY and will not fit the Genesis Coupe.
- When buying used, check carefully for hidden body filler with a magnet and inspect all mounting points for cracks.
- Be aware of major vehicle safety recalls for fire risk related to the ABS module and starter solenoid, which are unrelated to the fender itself but important for any owner.
Key Compatibility Information: The Hyundai Genesis Connection

The most important fact to know when shopping for a 2017-2020 Genesis G80 fender is that the part is identical to the fender used on the 2015-2016 Hyundai Genesis Sedan. The Genesis G80 was a direct continuation and rebranding of the Hyundai Genesis sedan. This shared design means that used or new parts listed for the 2015-2016 Hyundai Genesis Sedan will fit your 2017-2020 G80 perfectly, significantly widening your search options.
Warning: This interchange applies only to the 4-door sedan models. These fenders will NOT fit the Genesis Coupe, which is a completely different vehicle.
Signs You Need to Replace Your Fender

Unlike mechanical parts, fenders don't 'fail' electronically or wear out over time. Replacement is almost always due to physical damage. Here’s what to look for:
- Collision Damage: This is the most common reason. Heavy impacts can leave the fender crumpled, creased, or torn, making repair impossible or more expensive than replacement.
- Significant Dents or Creases: While small dings can sometimes be fixed with paintless dent repair (PDR), larger dents or sharp creases weaken the metal and are difficult to fix without using large amounts of body filler, which can crack over time.
- Rust Corrosion: Look for bubbling paint or visible rust, especially along the wheel arch, the bottom edge near the rocker panel, and around mounting points. Surface rust can sometimes be treated, but if the metal is perforated (rusted through), the fender's structural integrity is compromised and it must be replaced.
- Cracks or Tears: Stress from a minor impact or vibration can sometimes cause cracks to form in the metal, especially near mounting points. A cracked fender is unsafe and should be replaced.
Buying a Used Fender: What to Inspect

A high-quality, recycled OEM fender is often a better choice than a cheap aftermarket part due to superior fit, material quality, and finish. Here’s how to inspect a used fender before buying:
- Check for Hidden Repairs: Look at the backside of the fender for signs of previous work. Run a small magnet over the entire surface; if it fails to stick in certain areas, it indicates the presence of Bondo or other body fillers, signaling a prior repair. Avoid these parts.
- Inspect All Mounting Points: Carefully check every bolt hole and mounting tab. Ensure they are intact, not cracked, bent, or elongated. Damaged mounting points will make proper alignment impossible.
- Examine the Edges for Rust: Pay close attention to the inner lip of the wheel arch and the bottom edge. This is where moisture collects. Peel back any rubber trim if possible to check for hidden corrosion.
- Sight Down the Body Lines: Hold the fender up and look down its length. Check for subtle waves, ripples, or distortions that might indicate a poorly repaired dent. It should be perfectly straight and smooth.
- Verify the Part Number: If possible, check for a sticker or stamp with the OEM part number. The correct numbers for this generation are 66310-B1000 for the left (driver) side and 66320-B1000 for the right (passenger) side.
Vehicle-Specific Recalls and Issues (Not Fender-Related)

While there are no known recalls or technical service bulletins (TSBs) specifically for the fenders on the 2017-2020 Genesis G80, prospective buyers and owners should be aware of several important safety recalls for the vehicle itself. These issues do not involve the fender, but are critical for overall vehicle safety.
- Fire Risk from ABS Module: A recall was issued because the Anti-Lock Brake System (ABS) module could malfunction and cause an electrical short, increasing the risk of an engine compartment fire, even when the vehicle is parked. The remedy involves replacing a fuse. Owners were advised to park outdoors and away from structures until the repair was completed.
- Fire Risk from Starter Solenoid: Another recall addresses water entering the starter solenoid, which can cause an electrical short and lead to a fire while parked or driving.
- Turbocharger Oil Pipe Leak (3.3T Engine): Models with the 3.3L turbocharged engine were recalled because a loose seal on the turbocharger oil supply pipe could leak oil onto the hot exhaust manifold, creating a fire risk.
Before purchasing a vehicle, it is highly recommended to check its VIN on the NHTSA website to see if any open recalls apply.
Cost Comparison: Fender Replacement
The cost of the fender itself is only part of the total expense. Painting and labor are significant factors.
| Part/Service | Estimated Cost | Notes |
|---|---|---|
| New OEM Fender | $370 - $570 | Genuine Hyundai/Genesis part. Comes unpainted. |
| New Aftermarket Fender | $150 - $320 | Primed, may require more prep work for a perfect fit. CAPA-certified parts offer better quality. |
| Used OEM Fender | $150 - $400 | Best value. Price depends on condition. Will require repainting unless you find a perfect color match. |
| Shop Labor (Installation) | $100 - $250 | Typically 1-2 hours of labor for a straightforward swap. |
| Shop Labor (Painting) | $300 - $900+ | Highly variable. Includes prep, paint, clear coat, and blending into adjacent panels (door/hood) for a perfect match. |
| Total Professional Replacement | $800 - $1,800+ | Includes a new part, paint, and installation at a professional body shop. |
Frequently Asked Questions (FAQ)
Is the fender on the driver's side the same as the passenger's side?
No, they are not interchangeable. They are mirror images of each other. You must order the correct side for your vehicle: Left (Driver Side) or Right (Passenger Side).
Do I need to paint a new fender?
Yes. Both new OEM and new aftermarket fenders are typically sold with only a black primer coat. This primer is not designed to protect against the elements and must be properly sanded, painted with your vehicle's color code, and clear-coated by a professional body shop for a lasting, matching finish.
Can I replace the fender myself?
Yes, if you have mechanical experience and basic tools. The process involves removing the front wheel, the plastic fender liner, and unbolting the fender from the bumper, A-pillar, and chassis. The most difficult part is achieving perfect panel gaps with the hood, door, and bumper during installation. For this reason, it has a moderate difficulty rating (3 out of 5).
Will a fender from a 2015 Hyundai Genesis really fit my 2019 Genesis G80?
Yes, provided it is from the 4-door sedan model. The body shell for the 2015-2016 Hyundai Genesis Sedan and the 2017-2020 Genesis G80 sedan is the same. This interchangeability is confirmed by OEM part catalogs and aftermarket parts suppliers.
