2018-2023 Kia Rio Sedan Back Glass: Defroster, Solar Tints, and Replacement Facts
This guide covers the essential details for replacing the back glass on your 2018-2023 Kia Rio sedan, including how to identify the correct solar version and what to inspect on a used part.
- This back glass is for 2018-2023 Kia Rio SEDAN models only; it will not fit the hatchback.
- Before buying, verify your vehicle requires the SOLAR glass version, which has special UV and heat-blocking properties.
- When inspecting a used part, check the defroster grid lines and electrical connectors for any breaks or damage, as this is a common failure point.
- Replacement is not a DIY task. It requires professional installation to ensure a safe and leak-proof seal.
Key Compatibility Warning: Sedan Models Only
Warning: This back glass (OEM part number 87110H9220) is designed exclusively for the 2018-2023 Kia Rio SEDAN. It will not fit the 5-door hatchback model due to differences in size and curvature. Always confirm your vehicle is a 4-door sedan before purchasing.
Symptoms of Failure
Back glass failure is usually obvious, but issues with its integrated features can also signal a problem.
- Visible Cracks or Shattering: The most common failure is breakage from impacts, road debris, or accidents. Even a small chip can spread over time, weakening the glass.
- Defroster Not Working: If the rear defroster fails to clear frost or condensation, it often points to a break in the fine orange or brown lines of the heating grid on the glass. It can also be caused by a damaged electrical connector at the edge of the glass.
- Water Leaks or Wind Noise: A humming or whistling sound from the rear of the car, especially at high speeds, can indicate a failing adhesive seal around the glass. Water stains on the interior trim or condensation inside the car are also clear signs of a bad seal.
Known Issues, TSBs, and Recalls
As of early 2026, there are no specific recalls or widespread factory defects reported to the National Highway Traffic Safety Administration (NHTSA) for the back glass on 2018-2023 Kia Rio models. While some older Kia models have had recalls for windshield bonding, this issue does not apply to the Rio of this generation. Any failures are typically due to external factors like impacts or improper installation after a prior replacement.
Buying a Used Back Glass: What to Inspect
Purchasing a used OEM back glass is an excellent way to save money while ensuring a perfect fit. However, a thorough inspection is crucial before you buy.
1. Confirm Compatibility (Sedan & Solar)
- Sedan Fitment: Double-check that the glass is from a 4-door sedan, not a 5-door hatchback.
- Solar Glass Verification: This part is the 'solar' version, which helps block UV and infrared rays to keep the car cooler. To verify, look for a 'SOLAR' marking printed on the glass, often near the other manufacturer logos. If there are no markings, the slight tint of the glass should match the tint of your vehicle's other windows.
2. Inspect the Defroster Grid and Connectors
This is the most critical inspection point for a used back glass.
- Grid Lines: Carefully examine every horizontal line of the defroster grid. Hold the glass up to a light source. Look for any scratches or breaks in the thin orange/brown lines. Even a tiny break can cause the entire defroster system to fail.
- Electrical Tabs: Locate the metal electrical connector tabs, usually found on the sides of the glass. Ensure they are firmly attached and not broken, cracked, or pulled away from the glass. This is a common point of damage when glass is removed from a donor vehicle. 🎬 See how to fix a broken defroster connector tab
3. Check for Physical Damage
- Scratches and Pits: Minor surface scratches are acceptable, but deep scratches that you can catch with a fingernail can be distracting and may compromise the glass strength.
- Edge Chips: Pay close attention to the outer edges of the glass. Any chips or fractures, no matter how small, make the glass vulnerable to cracking during installation or from temperature changes.
Pro Tip: Using an original equipment (OEM) used part is often better than a cheap aftermarket one. OEM glass guarantees the correct curvature, thickness, and alignment for a leak-free fit and proper defroster connections, which can be problematic with some non-OEM parts.
Replacement Cost & Difficulty
Replacing a back glass is not a DIY-friendly job. It requires specialized tools, powerful urethane adhesives, and precise techniques to ensure a safe, weatherproof seal. An improper installation can lead to dangerous water leaks, wind noise, or even the glass detaching in an accident.

Frequently Asked Questions (FAQ)
Can I repair a broken defroster line on the back glass?
Yes, in many cases you can. Auto parts stores sell special repair kits that contain a conductive paint or epoxy. You carefully apply it over the break in the grid line to restore the electrical connection. 🎬 Watch: How to repair a broken defroster grid This is a cost-effective fix if the rest of the glass is in good condition.
What is the difference between solar glass and regular tinted glass?
Regular tint is a film or dye that primarily darkens the glass to reduce visible light. Solar glass has a special metallic or ceramic coating embedded within the glass that reflects or absorbs specific non-visible light waves, like ultraviolet (UV) and infrared (IR) rays. This helps keep the car's interior cooler and protects it from sun damage.
Will this back glass fit my 2019 Kia Rio5 hatchback?
No, it will not. The back glass for the 4-door sedan and the 5-door hatchback are different shapes and sizes. This part is only for the sedan.
Is it safe to drive with a shattered back window?
It is not recommended for more than a short, necessary trip. A missing back window exposes the cabin to weather and road debris, compromises vehicle security, and can allow dangerous exhaust fumes to be pulled inside the car while driving. It's best to get it covered with automotive plastic and tape immediately and schedule a replacement.
