Repairing Plastic Under Your Car: How Much Does It Cost?

The cost of repairing or replacing the plastic panel or shield under a car can vary widely depending on the make and model of the car, the extent of the damage, and whether the owner chooses to purchase OEM parts or aftermarket alternatives. Some car owners have reported spending between $18 and $400 to replace the plastic under their cars, with one BMW owner reporting a $300 quote to fix underbody plastic. In some cases, car owners may be able to repair minor damage with simple tools, but more extensive damage may require a full panel replacement.

Cost of fixing plastic under car

The cost of fixing plastic under a car can vary depending on several factors, including the extent of the damage, the make and model of the car, and whether you choose to repair or replace the plastic yourself or with the help of a professional.

If the damage is minimal, you may be able to fix it yourself with basic tools and some effort. This can help you save on labour costs that a mechanic or dealership would otherwise charge. However, if the plastic panel, also known as a splash shield or belly pan, is severely damaged or missing, you will likely need to replace it with a new one.

The price of a replacement plastic panel can vary depending on the car's make and model. For example, some Hyundai owners have reported being quoted over $400 to replace the plastic shield under their cars. In contrast, others have found aftermarket parts for a fraction of the price, with one person purchasing a replacement shield for their 2011 Elantra for only $18.

It's important to note that the plastic panel under your car plays a crucial role in protecting the undercarriage from debris, dirt, and moisture. A damaged or loose panel can lead to noise, reduced aerodynamics, and potential damage to other car parts. Therefore, it is recommended to address any issues with the plastic under your car promptly to avoid more costly repairs down the road.

When deciding whether to fix or replace the plastic yourself or seek professional help, consider your level of comfort and expertise in car repairs. If you're unsure about anything, it's always best to consult a trusted mechanic or dealership to ensure the job is done correctly and safely.

DIY fixes

The plastic panel under your car, also known as a splash shield or belly pan, is designed to protect the undercarriage of your car from dirt, debris, and water. However, it can easily get damaged by curbs, speed bumps, or rough terrain. Depending on the severity of the problem, you may need to replace the panel entirely or simply reattach it.

If the damage is minimal, you may be able to fix it with simple tools and some elbow grease. Here are the steps you can follow:

• Inspect the plastic panel under your car and determine the extent of the damage.
• Gather the necessary tools and materials, including a socket wrench set, screwdrivers (flathead and Phillips), safety goggles, and zip ties or bungee cords.
• Locate the fasteners that are holding the plastic panel in place. These are usually plastic screws or bolts.
• Remove the fasteners with a socket wrench or screwdriver.
• Gently pull the panel away from the underside of your car.
• If you are reattaching the panel, make sure to get the right size and model for your car.
• Secure the panel in place with zip ties or bungee cords to prevent it from vibrating or coming loose.
• Test drive your car and listen for any rattling or scraping noises.
• If everything seems fine, do a final inspection of the plastic panel once you arrive at your destination. Check for any signs of damage or movement, and adjust the fasteners or ties/cords as needed.

If the panel is severely damaged or missing entirely, you will need to replace it with a new one. You can find replacement plastic panels online or at your local auto parts store. Make sure to get the right size and model for your car. Additionally, you can find aftermarket parts that are compatible with your car's make and model, which can be much cheaper than OEM parts.

When to replace plastic under car

The plastic under your car, also known as a splash shield, splash guard, or belly pan, is designed to protect the undercarriage of your car from dirt, debris, and water. It also helps to reduce the vehicle's drag for a smoother ride and prevents mud, water, ice, and snow from entering the wire slots and rusting metal parts.

Over time, this plastic panel can become damaged or loose, dragging on the road and potentially causing noise, reducing aerodynamics, and leading to costly repairs if other parts of your car are affected. So, when should you replace the plastic under your car? Here are some key indicators:

• Damage: If the plastic panel is severely damaged, cracked, or missing entirely, it's definitely time to replace it. Minor damage may be fixed with simple tools and some extra effort, but extensive damage will require a new panel.
• Loose fasteners or dragging: Loose or missing fasteners can cause the plastic panel to drag on the road. Regularly check the panel's fasteners and adjust or tighten them as needed. If the panel is dragging, it needs to be reattached or replaced to avoid further issues.
• Noise: A scraping or rattling noise while driving could indicate a loose or damaged plastic panel. Inspect the panel and make the necessary repairs or replacements.
• Age and appearance: If the plastic panel is too old or scratched, it may be wise to replace it. This will help maintain the aesthetics of your vehicle and ensure the panel is functioning optimally.
• Extreme weather or road conditions: Driving through bumpy roads, hitting hard objects, or navigating in extremely cold weather can cause damage to the plastic panel over time. If you frequently encounter such conditions, consider regular inspections and replacements as needed.

When replacing the plastic panel, it's important to use the right tools, take your time, and be cautious when working under your vehicle. Ensure you purchase the correct size and model for your car, and consider seeking professional help if you're unsure about anything.

Damage prevention

The plastic panel underneath your car, also known as a splash shield or belly pan, is designed to protect the undercarriage of your car from dirt, debris, and water. This plastic cover is crucial for safeguarding sensitive parts from damage and corrosion.

Regular Inspection

Regularly inspect the plastic panel for any signs of damage, movement, cracks, holes, broken clips, or loose parts. Check for any trapped debris that could cause corrosion or further damage. It is recommended to inspect the panel at every oil change or service interval.

Clear Drainage Holes

Ensure that the drainage holes are clear to prevent water buildup. Long-term exposure to moisture can lead to rust or mildew, which can affect the structural integrity of the car.

Secure Fasteners

Check that the fasteners holding the plastic panel in place are secure and tight. If any fasteners are missing or loose, replace or tighten them accordingly. Additionally, you can reinforce the panel with zip ties or bungee cords to help hold it in place and prevent it from vibrating or coming loose.

Avoid Rough Terrain

The plastic panel can easily get damaged by curbs, speed bumps, or rough terrain. Whenever possible, avoid driving on rough surfaces or roads with a lot of potholes.

Test Drive

After any repairs or adjustments to the plastic panel, test drive your car and listen for any unusual noises. Pay attention to how the car handles and check for any signs of movement or damage to the panel after driving.
