The 6th generation Hyundai Elantra (produced from 2017 to 2020) is celebrated for its rigid "SuperStructure" high-strength steel chassis and its fluid, aerodynamic roofline. A critical element of this sweeping design is the rear quarter glass, seamlessly integrated into the C-pillar to complete the vehicle's aesthetic while contributing to structural integrity and cabin noise reduction. When this specific window shatters—whether from a break-in, vandalism, or an unexpected road hazard—it instantly compromises your vehicle's security, exposes your interior to harsh weather, and leaves dangerous glass shards scattered throughout your cabin. Because this encapsulated glass panel sits flush against the complex body lines of the AD-chassis Elantra, replacing it is not a job for an amateur. It requires exact precision, specialized tools, and a masterful understanding of automotive glazing.
Why Immediate Quarter Glass Replacement is Crucial for Your 2017-2020 Hyundai Elantra
Unlike laminated windshields that crack or spiderweb upon impact, the quarter glass on your Hyundai Elantra is manufactured from tempered safety glass. By design, when tempered glass sustains critical damage, it instantly shatters into thousands of small, blunt fragments. While this engineering marvel prevents deep lacerations during accidents, it creates an immediate emergency for the vehicle owner. A missing quarter glass panel provides an open invitation to thieves and leaves your sophisticated interior electronics exposed to rain, snow, and humidity.
Furthermore, driving with a missing quarter window disrupts the aerodynamic flow of the Elantra, creating deafening wind noise and destabilizing cabin pressure. To restore your vehicle to its factory-original condition, a professional replacement using OEM-equivalent glass, premium adhesives, and precise alignment is strictly necessary.

Master Technician’s Step-by-Step Quarter Glass Replacement Process
Replacing the quarter glass on a 2017-2020 Hyundai Elantra is a highly technical procedure. Because this glass is encapsulated with a rubber molding and bonded directly to the vehicle's pinch weld using structural adhesive, the removal and installation must be executed flawlessly. Here is our rigorous, A-to-Z replacement process at AlexWindshield:
Step 1: Vehicle Assessment and Interior Protection
Before any physical work begins, our master technicians conduct a thorough inspection of the vehicle's body lines, paint condition around the C-pillar, and the extent of the glass damage. We then apply heavy-duty protective drop cloths over your Elantra’s rear seats, floor mats, and trunk area. We also apply low-tack protective masking tape around the exterior paint of the C-pillar to ensure absolutely no scratches occur during the cut-out process.
Step 2: Intensive Vacuuming and Shard Removal
Because the quarter glass is tempered, thousands of glass shards will be embedded in your vehicle's interior. We use high-powered HEPA-filter shop vacuums to meticulously extract every piece of broken glass. We carefully pull back the rear seat bolsters, vacuum inside the seat belt receptacles, and clear out the rear parcel shelf. Ensuring your family's safety from hidden glass splinters is our top priority.
Step 3: Removing Interior Trims and the Damaged Glass Assembly
To access the bonding area of the quarter glass, we must carefully remove the interior C-pillar trim panels. Using specialized non-marring nylon pry tools, we detach the interior plastics without breaking the delicate retaining clips, being extremely careful to avoid interfering with the Elantra’s side curtain airbag system. Once the interior is accessible, we use an advanced wire-cutting system or a specialized cold knife to slice through the original factory urethane holding the remaining glass and rubber encapsulation to the body frame.
Step 4: Pinch Weld Preparation and Cleaning
The structural integrity of the new quarter glass depends entirely on the preparation of the metal frame, known as the pinch weld. Our technicians carefully use a razor scraper to trim the old urethane adhesive bead down to a uniform 1 to 2 millimeters. We never scrape down to bare metal unnecessarily, as the existing factory urethane provides an excellent base. We then use a specialized, alcohol-based pre-cleaner to thoroughly degrease the pinch weld, removing all dirt, road grime, and moisture.
Step 5: Applying Advanced Primer for Rust Prevention and Adhesion
If any minor scratches occurred on the pinch weld during the removal process, we apply a high-quality bare metal primer to seal the scratch and prevent future rust formation—a vital step for vehicles enduring harsh GTA winters. Next, we apply a specialized glass primer to the ceramic frit band of your new Hyundai Elantra quarter glass. This primer acts as a chemical bonding agent, ensuring the adhesive creates an unbreakable molecular bond with the glass.
Step 6: Precision Application of High-Quality Urethane Adhesive
We strictly use premium, automotive-grade, high-modulus urethane adhesive. Using an electric caulking gun, our technicians apply a perfect, continuous triangular bead of urethane around the pinch weld. The triangular shape is an industry standard that guarantees the adhesive will compress evenly when the glass is set, eliminating the risk of air gaps, wind whistling, or water leaks.
Step 7: Setting the New Hyundai Elantra Quarter Glass
With the adhesive precisely applied, we carefully align the new, OEM-quality quarter glass into the vehicle's opening. The 2017-2020 Elantra quarter glass features an integrated rubber molding (encapsulation) that must sit perfectly flush against the sheet metal. We gently press the glass into the urethane, ensuring exact depth and alignment with the vehicle's aerodynamic curves. Retention tape is temporarily applied to hold the glass firmly in place while the urethane begins its rapid chemical curing process.
Step 8: Final Inspection, Reassembly, and Post-Installation Cleanup
Once the glass is set, we reinstall the interior C-pillar trim panels, ensuring every clip snaps back securely into its original factory position. We then conduct a secondary, exhaustive vacuuming of the entire rear cabin to catch any microscopic glass dust that may have shifted during the repair. Finally, we clean the new quarter glass with streak-free automotive glass cleaner and conduct a rigorous water leak test to guarantee a watertight seal.
Commitment to OEM-Quality Materials
A vehicle as refined as the 2017-2020 Hyundai Elantra deserves parts that match its original engineering. At AlexWindshield, we only source auto glass that meets or exceeds Original Equipment Manufacturer (OEM) specifications. This means the encapsulation rubber will perfectly match the weathering resistance of your original glass, the tint hue will be identical to your rear door windows, and the ceramic frit band will perfectly shield the urethane from UV degradation. We never cut corners with cheap, aftermarket knock-offs that fade, warp, or leak over time.
