What the 87611-AA000 Set Covers

The Left & Right Mirror Glass (Non-Heated) for Hyundai Elantra 2021-2024 (Koeep P/N 87611-AA000) is a precision-engineered, second-surface silvered lens set for the Elantra CN7 platform, model years 2021-2024, Korea-built. The left lens runs under part number 87611-AA000, the right under 87621-AA000.

This variant complies with SAE J964 reflectance thresholds (50% minimum at 45° incidence), the ISO 3536:2026 safety-glazing protocols, and FMVSS 111 rear-visibility mandates that still govern the North American market through the 2026 regulatory cycle.

NHTSA is still evaluating camera monitoring systems (CMS) for future adoption. Reflective mirror glass therefore remains the federally mandated primary side-vision solution on every MY2026 Elantra trim, including the new SEL Sport Premium, which carries forward the identical CN7 mirror housing geometry.

Build Quality: Coating, Backing Plate, and Why Non-Heated

Second-surface mirroring on float glass

Automotive exterior mirrors use a second-surface design: the silvered coating sits on the rear face of the float glass, behind the full substrate thickness. Debris, moisture, and oxidation have to get through the glass before they reach the reflective layer, which is why this layout dominates the industry.

First-surface mirrors, common in precision optics, face the coating toward the light to kill ghost images and trade service life for clarity. A daily-driven Elantra needs the opposite priority, and the 2026 update to ISO 3536:2026 mandates enhanced accelerated-weathering resistance for all safety glazing, mirror glass included. The Koeep coating is vacuum-deposited Cr/Ag on 2.0 mm float glass from ISO 16293-certified production lines.

ABS backing plate and snap-fit retention

The injection-molded ABS backing plate replicates the OEM contour to a tolerance of ±0.15 mm across all three anchor points. That precision keeps the snap-fit lugs fully engaged with the factory actuator assembly and holds the correct adjustment range.

It also prevents the high-speed vibration CN7 owners report at 60-75 mph. Hyundai's TSB for mirror vibration on 2021-2024 Elantra models specifically calls out aftermarket glass with non-conforming backing plate geometry as a root cause. The ABS itself meets Hyundai material specification MS-210-05.

Why pick the non-heated lens

Heated versions of this lens carry the OEM suffixes -AA140 and -AA160. Removing the heating element and its connector eliminates the two most common failure modes in this assembly: terminal corrosion at the heating grid connector, and delamination from thermal cycling stress at the glass-to-backing-plate adhesive interface.

For moderate climates, or cars where the heated circuit is deactivated, this is the highest-reliability service replacement path. If your trim has heated mirrors, order the heated pair for the Elantra 2021-2024 (87621-AA040) instead.

Which Cars This Fits

The set fits Korea-built CN7 Elantra sedans from model years 2021, 2022, 2023, and 2024 in the non-heated, non-BSD configuration. BSD-equipped trims are out of scope; those need a BSD-compatible glass variant.

Koeep also lists the related 87611-2V110 non-heated mirror glass pair for the Hyundai Elantra, Veloster, Accent, and i30, useful if the household runs more than one Hyundai.

How the Replacement Goes In

This is a snap-in job with no housing removal, no actuator work, and no door panel. The backing plate carries three precision alignment lugs that engage the factory actuator carriage.

• Align the glass centrally over the actuator carriage.
• Press firmly and evenly until all three retention clips click.
• Run the power-adjust switch through its full range before the road test.

No scan-tool recalibration is required for non-heated, non-BSD variants. If a DTC appears after installation, inspect the actuator connector and wiring rather than the glass.

If vibration persists after the swap

Check the housing side first: loose mounting fasteners at the door-sail interface (torque spec 8-10 Nm) or worn actuator dampers. If the hardware is tight, the glass side is next, since a plate that fails to engage all three clips sets up a resonance at 60-75 mph. The ±0.15 mm tolerance on the Koeep plate targets exactly that failure.

2026 Compatibility and Market Outlook

The 2026 Elantra keeps the CN7 architecture with no structural change to the mirror housing, actuator, or glass retention system.

What the refresh actually changes

Trim realignment (SEL Sport Premium replaces SEL Convenience), interior material upgrades, and enhanced voice-recognition infotainment. None of it touches the mirror assembly, so the glass stays cross-compatible with MY2026 Korea-built cars in non-heated, non-BSD form. On SEL Sport Premium trims, check the heating and BSD setup before ordering.

Demand for reflective glass through 2030

The 87611-AA000 SKU carries a projected 2026-2030 service window, aligned with the CN7 generation's anticipated phase-out and the NHTSA's ongoing CMS review. FMVSS 111 still mandates physical reflective mirrors on all U.S.-market vehicles through at least the 2030 compliance horizon, even as Hyundai explores camera-based systems for premium markets.

The automotive glass aftermarket is projected to grow from USD 26.44 billion in 2025 to USD 34.91 billion by 2031, a 4.74% CAGR, driven by rising vehicle age at repair and the continued dominance of reflective glass in North American regulation.
