2023-2025 Toyota Prius & Prius Prime Rear Window Glass: A Replacement and Buyer's Guide
This guide covers the rear window glass for the 2023-2025 Toyota Prius and Toyota Prius Prime, including OEM part numbers, replacement costs, and what to inspect on a used part.
- The rear window glass is a structural component; replacement should only be done by a professional.
- There are no recalls for the rear window glass on these models; the major recall is for the rear door latches, which is a separate issue.
- When buying a used rear window, the most critical inspection point is the edges of the glass for any chips, which can lead to future failure.
- The OEM part number is 68103-47120, and a new part from a Toyota dealer costs between $160 and $240.
Symptoms of Rear Window Glass Failure
Unlike mechanical parts, the symptoms of rear window glass failure are usually immediate and obvious. The most common issue is breakage, but other problems can occur.
Complete Shattering
The most severe failure is the complete shattering of the glass. Because it is made of tempered safety glass, it is designed to break into thousands of small, relatively harmless pieces rather than large, dangerous shards. This can happen from an impact (like a rock or accident) or, more rarely, from thermal stress or a pre-existing flaw in the glass. If this occurs, the window will need immediate replacement.
Cracks or Chips
While less common on rear windows than on front windshields, impacts can still cause localized cracks or chips. A crack will compromise the structural integrity and weather seal of the vehicle and should be addressed promptly.
Defroster Grid Malfunction
You may notice that your rear defroster is no longer working or only clears certain sections of the glass. This is caused by breaks in the thin electrical lines that make up the defroster grid. These can be damaged by scratches (e.g., from loading cargo) or may fail over time.
Water Leaks
A failing urethane seal around the perimeter of the glass can allow water to leak into the cabin. This can lead to damp carpets, mold, and potential damage to interior electronics. This is more common after an improper replacement but can happen on original glass as well.
Important Note on Recalls: There is a widely known safety recall (NHTSA #24V274, expanded by #26V049) for the 2023-2024 Prius and Prius Prime concerning the rear door latches. This recall addresses an issue where water can enter the electronic door switches, potentially causing a door to open unexpectedly. This recall is NOT related to the rear window glass.
Buying a Used 2023-2025 Prius Rear Window Glass
Purchasing a used OEM rear window is an excellent way to save money compared to a new part from the dealer. Since this part doesn't wear out mechanically, a good used one is just as functional as a new one. However, careful inspection is key before you buy.
Inspection Checklist:
- Check for Scratches and Pits: Run your hand over the entire surface, inside and out. Deep scratches can impair visibility and weaken the glass. Minor surface scuffs are usually acceptable.
- Inspect the Edges for Chips: The perimeter of the glass is its most vulnerable area. Carefully inspect all edges for any chips or small cracks (sometimes called 'clamshells'). A small chip on the edge can propagate into a full shatter due to thermal stress or the vibrations of driving.
- Examine the Defroster Grid: Look closely at the horizontal lines of the defroster grid. Ensure there are no visible breaks or scratches through the lines. Pay special attention to the main electrical contact points (usually on the sides), making sure the connectors or tabs are intact and not damaged.
- Check for Delamination: Though rare on modern glass, look for any signs of the glass layers separating, which can appear as a milky or hazy area, usually starting from an edge.
- Verify Part Number and Features: Confirm the part is from a 2023-2025 Prius or Prius Prime. The OEM part number is 68103-47120. Ensure it has the features you need (defroster and antenna connections).
Pro Tip: When buying used glass, it's often sold still attached to a portion of the old urethane sealant. This is fine, as the installer will need to remove it anyway. The most important thing is the condition of the glass itself and its integrated components.
Replacement Difficulty and Procedure
Installation Difficulty: 5 out of 5 (Professional Recommended)
Replacing modern, bonded auto glass is not a DIY-friendly task. The rear window is bonded to the vehicle's frame with a strong urethane adhesive that contributes to the car's structural integrity. 🎬 Watch: Learn the 4 main principles of fixed glass replacement. A professional installation is highly recommended for safety and to prevent leaks.
The general process involves:
🎬 See this walkthrough of a Prius liftgate glass replacement.- Removing interior trim panels to access the glass perimeter.
- Using specialized tools, such as a cold knife or wire-out tool, to cut through the old urethane seal.
- Carefully removing the old glass without scratching the vehicle's paint.
- Cleaning the old urethane from the vehicle's pinch weld (the metal frame where the glass sits).
- Applying a new primer and a bead of automotive-grade urethane adhesive to the pinch weld or the new glass.
- Setting the new glass in place and allowing the urethane to cure for a specified time before the vehicle can be safely driven.

Frequently Asked Questions
Is the 2023-2024 Prius rear door recall related to the window glass?
No. The recall (NHTSA #24V274) is for the rear door latch mechanism, which can short circuit if water enters, potentially allowing the door to open while driving. It has nothing to do with the rear window glass itself.
Why did my Prius rear window shatter for no reason?
This is called spontaneous breakage. It's rare but can happen to any tempered glass. Causes include rapid temperature changes (thermal stress), an unnoticed chip or flaw from manufacturing, or damage to the edge of the glass that finally gives way due to driving vibrations.
Can I replace the rear window glass myself?
It is strongly advised not to. Replacing bonded glass requires special tools to remove the old window and precise techniques to apply the new urethane for a leak-proof, structurally sound installation. An improper installation can lead to dangerous water leaks, wind noise, and compromise the vehicle's safety. This is a job best left to professional auto glass technicians.
🎬 Watch: A professional demonstration of proper rear windshield installation.Is a shattered rear window covered by insurance?
Typically, yes, if you have comprehensive coverage on your auto insurance policy. This type of coverage usually handles non-collision events like glass breakage. You may have to pay a deductible.
