2003-2008 Subaru Forester Rear Spoiler: Installation, Color Codes & Fading Paint Guide
This complete guide covers common clear coat failure, installation steps for non-factory cars, and how to find the right used spoiler for your 2003-2008 Subaru Forester.
- The most common problem is peeling clear coat and paint due to sun exposure; finding a used spoiler with good paint is a major cost saver.
- Installation on a Forester without a factory spoiler requires drilling holes in the liftgate, a high-difficulty task.
- The spoiler fits all 2003-2008 (SG generation) Foresters, but finding a color-matched used one is key to avoiding repaint costs.
- The integrated third brake light uses a simple, replaceable bulb, making that repair easy and inexpensive.
Symptoms of a Failing or Damaged Rear Spoiler
Failure of a rear spoiler is typically cosmetic or related to the integrated brake light rather than a structural problem. Here are the most common symptoms owners experience:
1. Peeling or Fading Clear Coat
By far the most common issue with the spoiler on the SG Forester is cosmetic failure of the paint and clear coat. Because the spoiler is a plastic component that sits horizontally, it bears the full brunt of sun exposure. Over time, UV radiation breaks down the clear coat, leading to a hazy appearance, flaking, peeling, or a complete loss of the protective layer. This exposes the base color coat, which can then begin to fade and degrade.
2. Third Brake Light (CHMSL) Not Working
A non-functional third brake light is a safety hazard and will cause a vehicle to fail a safety inspection. On the 2003-2008 Forester, this is usually due to a simple burnt-out bulb. In some cases, the wiring that runs through the liftgate and into the spoiler can become chafed or broken, or the bulb socket itself may corrode. Unlike newer vehicles that may use an integrated LED strip, the SG Forester uses a replaceable bulb, making for a much simpler repair.
3. Physical Damage and Loose Fitment
Impacts from backing into objects, low-hanging garage doors, or aggressive automatic car washes can cause the spoiler to crack, chip, or break. The mounting points are the most vulnerable areas. If the spoiler becomes loose, you may hear rattling or vibrating noises from the rear of the vehicle, especially when closing the liftgate or driving over bumps. This indicates that the mounting nuts have loosened or the mounting studs on the spoiler itself have been damaged.
Pro Tip: Before assuming a rattle is the spoiler, check the rear seat latches. A well-known rattle on SG Foresters comes from a slight gap in the rear seat mounting locks, which can be fixed with a simple wrap of tape.
Buying a Used 2003-2008 Forester Rear Spoiler
A used OEM spoiler is an excellent, cost-effective option, especially if you can find one in the correct color. Here’s what to inspect before you buy:
- Inspect for Cracks: Carefully check the entire surface, paying close attention to the areas around the mounting studs. Flex the spoiler slightly to reveal any hidden stress cracks. A cracked mounting point will prevent the spoiler from sitting securely.
- Evaluate Paint and Clear Coat: Look for any signs of peeling, flaking, or severe fading. A spoiler with failed clear coat will need to be stripped and repainted, which can be costly. If the paint is in good shape, you can save hundreds of dollars.
- Check All Mounting Studs: Ensure all threaded mounting studs are present, straight, and have clean threads. If the spoiler was removed carelessly, these can be bent or broken off, making installation impossible. Ask if the seller includes the original mounting nuts and gaskets.
- Test the Third Brake Light: If possible, bring a 12-volt power source to test the third brake light. If the light doesn't work, it's likely just a bulb, but it gives you a point for negotiation. Check the wiring pigtail for any cuts or damage.
- Verify the Color Code: The easiest way to get a perfect match is to buy a spoiler from a vehicle with the same factory paint code. The original OEM part numbers included a two-letter suffix indicating the color (e.g., E721SSA000LR for Urban Gray Metallic). If you can't find a color-matched one, the next best option is a used spoiler in excellent physical condition that you can have repainted.
Known Issues, Recalls, and Technical Service Bulletins (TSBs)
There are no NHTSA recalls or widespread Technical Service Bulletins (TSBs) specifically for the rear spoiler on the 2003-2005 Subaru Forester. The most significant known issue is the aforementioned tendency for the clear coat and paint to fail due to sun exposure. While there were several recalls for the SG Forester platform, such as for front lower control arm corrosion in certain states, none pertain to the spoiler.
Installation Guide & Difficulty
Installation difficulty varies greatly depending on whether your Forester came with a spoiler from the factory.
- Replacing an Existing Spoiler: This is a straightforward job. The process involves removing the inner liftgate trim panel, disconnecting the third brake light wiring harness, unbolting the old spoiler (typically 4-5 nuts), cleaning the surface, and installing the new spoiler in reverse order.
- Installing a Spoiler on a Non-Equipped Vehicle: This is a much more involved process that requires precision and confidence. It involves using a paper template to mark the locations for drilling holes into your vehicle's liftgate. You must be extremely careful to drill in the correct spots. After drilling, the bare metal of the holes must be treated with touch-up paint to prevent rust before mounting the spoiler and running the wiring.
| Installation Type | Difficulty Rating | Estimated Time | DIY Feasible? |
|---|---|---|---|
| Direct Replacement | 2 / 5 | 0.5 - 1.0 Hours | Yes |
| New Install (Requires Drilling) | 4 / 5 | 1.5 - 2.5 Hours | Yes, for experienced DIYers |
Warning: When drilling into the liftgate, measure multiple times before making any holes. An incorrectly drilled hole is difficult to fix and can lead to rust or water leaks. Using an OEM or accurately scaled drilling template is highly recommended.
Cost Comparison for a 2003-2008 Forester Spoiler
Prices can vary based on condition and source. A professional repaint of a spoiler can cost an additional $200-$400.
| Part Type | Estimated Cost | Notes |
|---|---|---|
| New OEM (Primed) | $280 - $330 | Part number E721SSA010NN. Comes unpainted and requires professional painting. |
| New Aftermarket (Primed) | $80 - $150 | Made from ABS plastic, quality can vary. Requires painting. |
| New Aftermarket (Pre-Painted) | $250 - $300 | Offered by specialty spoiler shops. Verify their paint matching process. |
| Used OEM | $75 - $200 | Best value if you can find one in good condition with matching paint. Price depends heavily on paint condition. |
| Shop Labor (Installation) | $100 - $300 | Cost is lower for a direct replacement and higher if drilling and wiring are required. |
OEM Part Number Reference
The original spoilers were sold pre-painted, but these have largely been superseded by a single part number that comes primed.
| Part Number | Description | Fits Years |
|---|---|---|
| E721SSA010NN | Spoiler, Rear (Primed) | 2003-2008 |
| E721SSA000xx | Spoiler, Rear (Painted) | 2003-2008 |
Note: The 'xx' in the painted part number denotes a two-letter factory color code. Part number E721SSA010NN replaces most of the pre-painted versions.
Frequently Asked Questions (FAQ)
Can I install a spoiler if my Forester didn't have one?
Yes, but it requires drilling several holes in your liftgate. You will need a drilling template, a drill, and rust-proofing paint for the new holes. It's a job best left to those with some DIY experience to ensure proper alignment and prevent future rust issues.
How do I replace the third brake light bulb?
On the underside of the spoiler, there is a small access cover. Remove the screws holding this cover in place. This will expose the bulb socket. Twist the socket to remove it from the housing, pull out the old bulb, and insert the new one. Be careful not to touch the new bulb with your bare hands, as oils from your skin can cause it to burn out prematurely.
My spoiler's paint is peeling. What are my options?
You have three main options: 1) Replace it with a used, color-matched spoiler in better condition. 2) Remove the existing spoiler, have it professionally stripped, prepped, and repainted. 3) Attempt a DIY repair by sanding down the failed clear coat, re-spraying with color-matched paint and a 2K clear coat. The last option is the most affordable but requires significant prep work for a good result.
Is the spoiler just for looks?
No. While it certainly enhances the vehicle's appearance, it is also a functional aerodynamic part that helps with high-speed stability. More importantly, it houses the third brake light, which is a mandatory piece of safety equipment.
