2022-2025 Eclipse Cross Back Glass: Guide to the Facelift Model's Rear Window
This guide covers the single-pane back glass for the updated 2022-2025 Eclipse Cross, explaining how to distinguish it from the earlier split-window design and what to check before buying a used part.
- The back glass for the 2022-2025 Eclipse Cross is a single-pane design and is NOT compatible with the split-window design of 2018-2020 models.
- Replacement is not a DIY job; it requires professional tools and urethane adhesives to ensure a safe, leak-proof installation.
- When buying a used part, the most critical inspection points are the defroster grid lines and their electrical connectors, as damage here is common and not repairable.
- There are no active recalls or major known issues specifically for the back glass on this model range, making used OEM a reliable option if inspected properly.
Key Compatibility Warning: 2022 Facelift Model Change
Warning: The most important factor when purchasing a back glass for an Eclipse Cross is the model year. In 2022, Mitsubishi released a facelifted version of the Eclipse Cross which included a major redesign of the tailgate. Pre-facelift 2018-2020 models feature a distinctive split-glass or dual-window design. The 2022-2025 models use a conventional single-pane back glass. These two styles are not interchangeable. A back glass from a 2018-2020 model will NOT fit a 2022 or newer vehicle, and vice-versa.
Symptoms of a Failing Back Glass
Failure of a back glass is usually obvious, but can also include less dramatic symptoms related to its integrated features.
- Visible Cracks or Shattering: The most common failure is physical damage from an impact, which can range from a small chip to a completely shattered window.
- Malfunctioning Defroster: If the rear defroster fails to clear frost or fog, it's often due to broken electrical lines within the glass grid. This can happen from a scratch or impact, even if the glass itself isn't cracked.
- Water Leaks: Water entering the cargo area from the top or sides of the tailgate is a sign that the urethane adhesive seal has failed. This can lead to interior damage, mold, and corrosion.
- Wind Noise: A rattling, whistling, or humming sound from the rear of the vehicle at speed can indicate a bad seal around the glass.
Known Issues, TSBs, and Recalls
As of mid-2026, there are no specific recalls or widespread Technical Service Bulletins (TSBs) from Mitsubishi or the NHTSA concerning the back glass of the 2022-2025 Eclipse Cross. While some older Mitsubishi models have had recalls for issues like liftgate gas struts, these do not apply to the glass itself on the 2022+ Eclipse Cross. Forum discussions and owner complaints for this generation focus more on electrical systems or the pre-facelift model's styling, with no pattern of spontaneous glass failure reported.
Pro Tip: While there are no specific recalls for the glass, a related recall for 2022-2024 Outlander and 2023-2025 Outlander PHEV models involves a software error that can cause the rearview camera image to disappear. Since the camera is mounted near the tailgate, any work in this area should be followed by a check to ensure the camera functions correctly.
Buying a Used 2022-2025 Eclipse Cross Back Glass
A used OEM back glass can be a cost-effective alternative to a new part, offering the same fit and quality. However, a thorough inspection is crucial before purchasing.
Inspection Checklist:
- Confirm Compatibility: Double-check that the glass is from a 2022, 2023, 2024, or 2025 model year. Do not purchase if it's from an older, split-window model.
- Inspect for Scratches and Chips: Carefully examine the entire surface for any scratches, especially deep ones that could compromise integrity or damage a wiper blade. Pay close attention to the edges, as small chips here can lead to cracks later.
- Check the Defroster Grid: Look for any breaks, peeling, or scratches in the orange or brown horizontal lines of the defroster grid. A single broken line will cause the entire system to fail or work poorly.
- Examine Electrical Connectors: Inspect the electrical terminals where the defroster connects. Ensure they are not corroded, bent, or broken off the glass.
- Look for Intact Trim and Mounts: Some back glass assemblies may come with attached trim or mounting points for spoilers or wipers. Verify these are present and undamaged.

Installation Overview & Difficulty
Replacing a back glass is a complex and sensitive job that is not recommended for DIY mechanics without specific auto glass experience.
- Difficulty Rating: 5 out of 5
- Primary Challenge: The process requires specialized tools to cut the old urethane seal without damaging the vehicle's paint or body. Proper surface preparation of both the vehicle's pinch weld and the new glass is critical for a safe, leak-proof bond.
- Adhesive is Key: A specific type of automotive urethane adhesive must be used and allowed to cure for a specific amount of time (often several hours to a full day) before the vehicle can be safely driven. An improper bond can cause the glass to leak or, in a worst-case scenario, detach from the vehicle.
- Professional Installation: Due to the safety implications and specialized materials, professional installation is strongly recommended. A professional will ensure the defroster is correctly reconnected and that the seal is watertight.

Frequently Asked Questions (FAQ)
Can I repair a chip in the back glass like a windshield?
No. Back glass is made of tempered glass, which shatters into small pieces when damaged, unlike laminated windshield glass. Any significant chip or crack compromises the entire pane, requiring a full replacement.
Will my auto insurance cover a back glass replacement?
Typically, yes, if you have comprehensive coverage as part of your auto insurance policy. You will likely have to pay your deductible. It's best to contact your insurance provider to confirm your coverage details.
Why did my rear defroster stop working?
The most common cause is a break in one of the thin grid lines on the glass. It can also be caused by a bad electrical connection at the glass, a blown fuse, or a faulty switch. If the grid lines look intact, the other components should be checked before replacing the glass.
Is it safe to drive with a cracked back glass?
No. A cracked back glass can obstruct your rear view, making driving unsafe and potentially illegal. Because it is tempered glass, a small crack can cause the entire window to shatter unexpectedly, especially when hitting a bump or closing the tailgate. It should be replaced as soon as possible.
