2017-2023 Land Rover Discovery Spoiler: Damage, Leaks, and Replacement Costs
This guide covers common failure points, what to look for in a used part, and how to manage replacement for the 2017-2023 Land Rover Discovery rear spoiler.
- The most critical inspection when buying a used spoiler is to check that all mounting points are intact and free of cracks.
- New OEM spoilers come primed and require professional painting, adding significant cost to the replacement.
- Physical damage from automatic car washes is a known issue; one owner reported a car wash ripped the spoiler off entirely.
- Replacement is a moderately difficult DIY job that requires removing interior tailgate trim to access the mounting bolts.
Symptoms of Failure
A failing spoiler on a Land Rover Discovery typically shows physical signs of damage rather than causing performance issues. Since it's an exterior body part, problems are usually easy to spot.
- Visible Damage: The most common issue is physical damage from impacts, automatic car washes, or environmental factors. Look for cracks, deep scratches, or broken pieces. The spoiler is often made from ABS plastic or a composite material, which can become brittle over time.
- Loose Fitment or Rattling: The spoiler is secured with bolts and clips. If these fasteners become loose or break, the spoiler may vibrate or rattle, especially when driving at speed or closing the tailgate. In severe cases, the entire spoiler could feel loose to the touch.
- Paint and Clear Coat Failure: Like any painted body part, the spoiler is susceptible to peeling, fading, or bubbling of the clear coat and paint, especially with prolonged sun exposure.
- Water Leaks into the Tailgate: While not a widespread issue for this specific component on the 2017-2023 Discovery, poorly sealed or damaged spoilers on Land Rover vehicles have historically been a source of water ingress. A compromised seal around the spoiler's mounting points or the integrated third brake light could potentially allow water to enter the tailgate assembly, leading to issues with electronics or creating a damp, musty smell.
- Third Brake Light Malfunction: The spoiler houses the Center High-Mounted Stop Lamp (CHMSL). If this light stops working, it could be due to a failed LED unit, a loose connection, or water damage within the spoiler assembly.
Pro Tip: One owner reported an automatic car wash ripped the spoiler off their Discovery, leading to a costly repair that also involved replacing the tailgate due to distorted mounting points. It's wise to use touchless car washes or wash by hand to avoid stressing the spoiler and its mountings.
Buying a Used Spoiler
A used OEM spoiler is an excellent alternative to a costly new part, but careful inspection is key to getting a good one. Aftermarket options are available, but they may not match the OEM quality, fit, or material durability.
Inspection Checklist:
- All Mounting Points Intact: This is the most critical check. The spoiler attaches with several bolts and clips. Carefully inspect every mounting tab and screw hole. Ensure none are cracked, broken off, or stressed. A spoiler with even one broken mounting point will not fit securely and will likely rattle or detach.
- Check for Cracks and Structural Damage: Flex the spoiler gently and inspect it under good light. Look for hairline cracks, especially around the mounting points and corners. Minor surface scratches can be repaired, but structural cracks are a major red flag.
- Condition of Integrated Components: If the used spoiler includes the third brake light or washer nozzle, check their condition. Look for clear, un-faded lenses on the brake light and ensure the nozzle is not clogged or broken. Ask the seller if the light was tested and is functional.
- Verify Part Numbers: Ensure the part number matches what's required for your vehicle. The primary OEM part number is LR173164, which supersedes older numbers like LR083201 and LR135600. Providing your vehicle's VIN to the seller is the best way to guarantee fitment.
Known Issues, TSBs, and Recalls
While searches for the 2017-2023 Discovery did not reveal specific recalls for the spoiler, older Land Rover models have had recalls for similar issues. For example, 2010-2011 Range Rover Sport models were recalled (NHTSA Recall 20V-623) because the adhesive bond could fail, causing the spoiler to detach from the vehicle. This highlights the importance of secure mounting, whether with adhesive or mechanical fasteners.
A Technical Service Bulletin (TSB), LTB01250NAS1, was issued for the 2018 Discovery Sport (a different model) for an incorrect gap between the rear spoiler and the D-pillar, which could cause a clash. This indicates that proper alignment and fitment are critical factory specifications.
Cost Comparison
Prices can vary based on condition, supplier, and whether the part is new or used. New spoilers from Land Rover typically come primed and require painting, which adds to the total cost.
| Part Type | Estimated Cost | Notes |
|---|---|---|
| New OEM | $790 - $940 | This is for the part only, typically primed and unpainted. |
| New Aftermarket | $250 - $500 | Quality and fit can vary. Often made from different materials like ABS plastic or fiberglass. |
| Used OEM | $350 - $800 | Price depends heavily on condition, color, and whether it includes the brake light. |
| Shop Labor (Installation) | $150 - $300 | Estimated 1-2 hours of labor. May be higher if interior tailgate panels need to be removed. |
| Painting | $200 - $400 | Required for new primed spoilers to match your vehicle's color. |
Replacement Overview
Replacing the rear spoiler is a moderately difficult task. While it doesn't require highly specialized tools, it does demand care to avoid damaging the tailgate paint or the spoiler itself. The process involves removing interior trim panels from the tailgate to access the mounting nuts and bolts, as well as disconnecting the wiring for the third brake light and the hose for the washer jet.
- Difficulty: 3 out of 5
- Estimated Time: 1.5 - 2.5 hours
- Tools Needed: Socket set, trim removal tools, possibly a heat gun if adhesive is present.
Warning: On some Land Rover models, the spoiler or its integrated brake light is bonded to the tailgate with strong adhesive in addition to bolts. Removing it can be very difficult and may require cutting the adhesive with specialized tools or heat. Attempting to force it off can damage the tailgate.
Frequently Asked Questions (FAQ)
Can I drive with a damaged or missing spoiler?
You can drive without a spoiler, but it's not recommended if it's loose. A loose spoiler could detach at speed, creating a serious hazard for other drivers. A missing spoiler will leave mounting holes exposed, allowing water to enter the tailgate, and will also mean your vehicle is missing its third brake light, which is a safety issue and may be illegal in some areas.
Does a new OEM spoiler come painted?
No, new OEM spoilers from Land Rover are typically sold in a primed state, ready for painting. You will need to have a body shop paint the spoiler to match your vehicle's color, which is an additional cost.
Is it difficult to replace the spoiler myself?
It is a moderately difficult DIY job. You need to be comfortable removing interior trim panels without breaking clips and carefully handling electrical connectors and washer fluid lines. The main challenge can be accessing the fasteners and, if applicable, dealing with any factory adhesive. Reviewing a video of the process for a similar Land Rover model is highly recommended before starting.
Why is a used OEM spoiler often a better choice than a new aftermarket one?
A used OEM spoiler guarantees a perfect fit, proper mounting locations, and material quality that matches the original factory part. Aftermarket spoilers can have issues with fitment, hole alignment, and may be made from lower-grade materials that don't hold up as well over time. If you can find a used OEM spoiler in the correct color and good condition, it is often the most cost-effective and reliable solution.
