2022-2025 Eclipse Cross Rear Spoiler: Third Brake Light Failure, Fitment, and Paint Codes
Your complete guide to diagnosing, replacing, and buying a used OEM rear spoiler for the facelifted Mitsubishi Eclipse Cross.
- This spoiler fits ONLY the 2022-2025 'facelift' Mitsubishi Eclipse Cross models.
- The most common failure is the non-replaceable integrated LED third brake light, which requires replacing the entire spoiler assembly.
- OEM part number suffixes (e.g., RA, BA, XA) denote factory paint codes; match them to avoid the cost of repainting.
- When buying a used spoiler, the most important check is to verify that the LED brake light is functional before purchase.
Key Compatibility Warning: 2022+ Facelift Models Only
Warning: This rear spoiler is specifically designed for the 2022, 2023, 2024, and 2025 Mitsubishi Eclipse Cross models. These are often called 'facelift' models because they received a significant styling update. This part will NOT fit the earlier 2018-2020 Eclipse Cross due to major differences in the liftgate design.
Symptoms of a Failing Rear Spoiler
Since the spoiler is a solid-state body part, 'failure' almost always refers to the integrated third brake light or physical damage.
- Third Brake Light (CHMSL) Not Working: The most common issue is the failure of the integrated LED third brake light. It may not light up at all, flicker, or appear dim. This is a safety concern and can result in a traffic ticket.
- Physical Damage: Cracks, deep scratches, or scuffs from impacts are common. Pay close attention to the mounting points, as stress cracks can form there, leading to a loose fit.
- Water Leaks into the Liftgate: If the spoiler's seals or mounting gaskets fail, water can seep into the internal structure of the liftgate. You might notice moisture inside the upper liftgate trim panel or water running out when you open the hatch after it rains.
- Loose Fitment: The spoiler may feel loose or rattle when you open or close the liftgate. This is usually caused by loose mounting nuts or broken mounting points on the spoiler itself.
Known Issues, TSBs, and Recalls
As of this writing, there are no specific recalls or Technical Service Bulletins (TSBs) from Mitsubishi or the National Highway Traffic Safety Administration (NHTSA) that directly address the rear spoiler or its integrated third brake light for the 2022-2025 Eclipse Cross. General troubleshooting for brake light failures points towards checking bulbs, fuses, and the brake pedal switch. However, since this spoiler uses an integrated LED assembly, the 'bulb' is not separately replaceable; the entire spoiler assembly must be replaced if the light fails.
Buying a Used 2022-2025 Eclipse Cross Spoiler
A used OEM spoiler is an excellent, cost-effective alternative to a new part, especially if you can find one in the correct color. Here’s what to check before you buy:
Inspection Checklist:
- Verify the Third Brake Light Works: This is the most critical check. Ask the seller to connect it to a 12V power source to confirm the LED strip illuminates fully and brightly. If testing isn't possible, buy from a reputable seller with a good return policy.
- Check for Cracks: Carefully inspect the entire spoiler, especially around the mounting bolt holes. Stress cracks here are a major red flag and can prevent the spoiler from seating securely.
- Inspect the Lens: Look for cracks, heavy clouding, or water intrusion in the red lens of the third brake light.
- Match the Paint Code: The last two letters of the OEM part number signify the factory color. Matching this saves you the significant cost of repainting. If you find a spoiler in a different color for a good price, factor in the cost of a professional repaint.
- Confirm All Mounting Points are Intact: Ensure none of the threaded studs or plastic clips are broken off. A spoiler with damaged mounting points will not install correctly and may leak or rattle.
Pro Tip: The wiring pigtail and connector should be intact. A cut or damaged connector will complicate the installation, requiring you to splice wires.

Replacement Overview
Replacing the rear spoiler is a straightforward job for a DIYer with basic tools. It involves removing interior trim panels to access the mounting hardware and electrical connector.
- Difficulty: 2 out of 5
- Estimated Time: 1 hour
- Tools Needed: Socket set, trim removal tools, screwdriver.
General Steps:
- Open the liftgate.
- Carefully pry off the upper interior trim panel from the liftgate to expose the spoiler's mounting nuts and wiring.
- Disconnect the electrical connector for the third brake light.
- Unbolt the several nuts holding the spoiler to the liftgate.
- Gently lift the old spoiler off. Clean the mounting surface on the liftgate thoroughly.
- Position the new spoiler, ensuring its gaskets are properly seated.
- Hand-tighten the mounting nuts, then torque them evenly to specification. Do not overtighten, as this can crack the spoiler.
- Reconnect the electrical connector and test the brake light before reinstalling the trim panel.
- Snap the interior trim panel back into place.

Frequently Asked Questions (FAQ)
Can I just replace the LED light instead of the whole spoiler?
No. The LED third brake light is integrated directly into the spoiler assembly and is not sold as a separate, replaceable part by Mitsubishi. If the light fails, the entire spoiler unit must be replaced.
Will this spoiler fit my 2020 Mitsubishi Eclipse Cross?
No, it will not. The 2022 model year marked a significant exterior redesign (facelift) for the Eclipse Cross, especially at the rear. This spoiler is only compatible with 2022 and newer models.
My spoiler is leaking water into the trunk. What should I do?
A water leak is typically caused by dried-out or compressed mounting gaskets. The best solution is to remove the spoiler, clean the mounting surfaces on both the spoiler and the liftgate, and apply a new bead of automotive-grade silicone sealant or replace the gaskets if they are available separately. Then, reinstall the spoiler and ensure the nuts are tightened evenly.
What do the letters at the end of the part number (like BA, RA, XA) mean?
These two-letter suffixes are Mitsubishi's codes for the factory paint color. For example, 6515A615RA is for a red vehicle, and 6515A615XA is for a black one. Matching these codes is the easiest way to get a part that doesn't need to be repainted.
