2018-2021 Kia Stinger Back Glass: Solar Options, Defroster Grids, and Replacement Guide
This guide covers the essential checks for buying a used Stinger back glass, from identifying solar tint to verifying the defroster grid is intact.
- The back glass is a structural part of the Stinger's liftback; professional installation with urethane adhesive is mandatory for safety and weather sealing.
- Before buying a used glass, verify if your vehicle requires standard or 'Solar Glass' to ensure a proper match for heat rejection and appearance.
- Critically inspect the defroster grid and its electrical connection tabs on any used glass; damaged tabs are generally not repairable.
- There are no major recalls or TSBs specifically for the back glass on the 2018-2021 Stinger, but spontaneous shattering is a known issue on some modern tempered glass.
Symptoms of Failure
Unlike mechanical parts, back glass failure is typically sudden and obvious. The primary symptom is breakage, but issues with integrated components can also occur.
- Visible Cracks or Shattering: The most common failure is physical damage from an impact. Tempered glass can also shatter from extreme, sudden temperature changes, though this is less common. Some owners of modern Kia vehicles have reported spontaneous shattering, which may be related to the rear defroster use or inherent stress in the glass.
- Defroster Not Working: If your rear defroster fails to clear frost or condensation, it's often due to a break in the orange or brown grid lines on the glass. This can happen from scratches or a manufacturing defect. The electrical tabs where the wiring connects to the grid can also become damaged or detached.
- Water Leaks: A failing urethane adhesive seal around the perimeter of the glass can allow water to leak into the cabin or trunk area. This can lead to mold, mildew, and damage to interior components.
Known Issues, Recalls, and Technical Service Bulletins (TSBs)
As of mid-2024, there are no specific recalls or Technical Service Bulletins (TSBs) issued by Kia or the NHTSA that directly address the back glass, defroster, or spontaneous shattering for the 2018-2021 Kia Stinger in the US market.
- Spontaneous Shattering Investigation: A law firm is investigating spontaneous rear window shattering on several 2021-2025 Hyundai and Kia models, though the Stinger is not explicitly listed in the primary group of affected vehicles. These incidents are often linked to tempered glass and may occur after using the rear defroster.
- Unrelated Recalls: The 2018-2021 Stinger has been subject to several other recalls, most notably for risks of engine compartment fires related to the Hydraulic Electronic Control Unit (HECU) (NHTSA Campaign SC196) and a deteriorating turbocharger oil feed pipe (NHTSA Campaign SC300). These issues are not related to the back glass itself.
Pro Tip: While the side windows on some Stingers have known issues with the motor or regulator failing, this problem does not apply to the fixed back glass.
Buying a Used 2018-2021 Stinger Back Glass
A used OEM back glass can be a cost-effective alternative to a new part, offering the same fit and quality. However, careful inspection is critical before purchase.
Physical Inspection Checklist
- Cracks and Chips: Meticulously inspect the entire surface, especially around the edges, for any cracks, chips, or "bullseyes." Even a small flaw can compromise the glass's integrity.
- Scratches: Check for deep scratches that could affect visibility or damage the defroster grid.
- Delamination: Look for any signs of separation or cloudiness around the edges, although this is more common on laminated windshields than tempered back glass.
- Defroster Grid and Connectors: This is one of the most important checks. Carefully examine the thin orange/brown lines of the defroster grid. Ensure there are no visible breaks or scratches across them. Crucially, inspect the metal electrical tabs (terminals) where the wiring harness connects. These are often soldered to the glass and are extremely fragile. If they are broken off or damaged, the defroster will not work and repair is nearly impossible.
Verifying Glass Options: Solar vs. Standard
Kia offers "Solar Glass" on many of its vehicles, which has a special coating or interlayer designed to reflect infrared (IR) rays, reducing heat buildup inside the car. This helps keep the cabin cooler and can improve A/C efficiency.
- How to Identify: Look for a small etching or label in one of the corners of the glass. It may say "SOLAR GLASS" or have a specific symbol. If you are unsure, comparing the tint and reflective properties to your vehicle's other windows can help. A purplish haze when viewed from the outside can sometimes indicate solar glass.
- Why It Matters: You should purchase a used glass that matches your vehicle's original type to maintain a consistent appearance and level of heat rejection. The primary OEM part number for the 2018-2021 Stinger back glass is 87111-J5010. It's important to confirm with the seller if this corresponds to the solar or standard version if your vehicle has this option.
Why a Used OEM Glass is Often a Good Choice
For a part like this, a used Original Equipment Manufacturer (OEM) glass is often superior to a new aftermarket one. OEM glass guarantees a perfect fit for the complex curves of the Stinger's liftback, ensures the tint color matches the rest of your vehicle's windows, and meets the original factory quality standards. Aftermarket glass can sometimes have slight variations in shape or tint that can lead to installation problems or an inconsistent look.
Replacement Cost & Difficulty
Replacing the back glass on a Kia Stinger is a job for professionals. The glass is large, heavy, and bonded to the vehicle's body with strong urethane adhesive. This process requires specialized tools and expertise to ensure a safe, leak-proof installation.
Warning: Do not attempt to replace bonded glass yourself without proper training and equipment. An improper installation can lead to dangerous water leaks, wind noise, and a compromised vehicle structure. The adhesive requires a specific curing time before the vehicle is safe to drive.
| Item | Estimated Cost |
|---|---|
| New OEM Back Glass (Part Only) | $700 - $900+ |
| New Aftermarket Back Glass (Part Only) | $250 - $450 |
| Used OEM Back Glass (Part Only) | $200 - $400 |
| Shop Labor & Materials (Adhesive, Primer) | $250 - $450 |
Note: Prices are estimates as of late 2024 and can vary significantly based on location, supplier, and whether the glass is standard or solar.
Frequently Asked Questions (FAQ)
Can I repair a broken defroster line on my Stinger's back glass?
Yes, minor breaks in a defroster grid line can often be repaired using a special conductive paint kit available at most auto parts stores. However, if the main electrical connector tab has broken off the glass, it is generally not repairable and the entire back glass will need to be replaced.
Is the back glass the same for all 2018-2021 Stinger trims (e.g., GT, GT-Line)?
The physical shape and size of the glass are the same across all trims for this year range. The main difference is the potential for solar vs. standard glass. Always verify which type your car has before purchasing a replacement.
Will my radio work with a replacement back glass?
In many modern vehicles, the radio antenna is integrated into the back glass. A proper OEM replacement will have the antenna built-in. When installing, the technician must ensure the antenna connection is properly re-established. Using an aftermarket glass without the correct antenna provision will result in poor or no radio reception.
What other parts might I need when replacing the back glass?
The glass itself is the main component, but you will always need a new tube of auto glass urethane adhesive and primer. Depending on how the old glass is removed, you may also need a new outer molding (Part # 87120-J5000). The liftback support struts (lift cylinders) are separate parts and are not typically replaced with the glass unless they are also failing.
