Do aftermarket parts void Subaru warranty?
Not automatically. Under the Magnuson-Moss Warranty Act and Subaru’s policy, installing aftermarket parts does not automatically void your entire Subaru warranty; however, coverage for any problem can be denied if the aftermarket part caused or contributed to the failure or if installation was improper. In practice, the rest of the vehicle’s warranty remains in effect if the issue is unrelated to the modification.
Understanding Subaru warranties
Subaru’s warranty structure in the United States typically includes a New Vehicle Limited Warranty, a Powertrain Limited Warranty, and a corrosion/through-perforation warranty. The basic warranty generally covers defects in materials and workmanship for a set period or mileage, while the powertrain warranty protects major drive-system components for a longer span. The corrosion warranty covers rust-related perforation issues. Terms can vary by model year and region, so it’s important to review your specific agreement and any dealer disclosures.
How aftermarket parts interact with warranty
The central principle is causation. Under the Magnuson-Moss Warranty Act, manufacturers cannot automatically void the entire warranty simply because aftermarket parts were installed. If an aftermarket component fails and causes a problem, Subaru can deny coverage for that particular issue. If the problem is unrelated to the modification, coverage typically remains intact, provided the vehicle has been properly maintained.
The following key ideas summarize how aftermarket parts relate to coverage:
- Warranty coverage stays in place for non-modified components unless the modification caused the failure.
- Dealers may deny coverage for problems specifically caused by aftermarket parts or improper installation.
- Keep documentation: receipts, installation details, and any warranties on aftermarket parts can support a claim.
- OEM replacement parts are not universally required to maintain warranty coverage, but service decisions can vary by case and dealership policy.
Conclusion: In practice, aftermarket parts do not automatically void Subaru’s warranty, but how a claim is handled depends on whether the modification contributed to the fault and on the quality of installation and maintenance.
Common scenarios
Engine tuning and ECU remapping
Performance tunes, ECU remaps, or horsepower-enhancing modules can affect engine behavior. If a fault arises and the tuner or remap is implicated, a dealer may limit or deny coverage for that issue while still honoring other, unrelated warranty items.
Suspension, exhaust, and intake modifications
Suspension kits, exhaust systems, and air intake changes are frequent aftermarket modifications. Coverage for issues related to these components depends on whether the problem stems from the modification or from unrelated wear and tear or defects in other parts.
Electronic accessories
Aftermarket radios, lighting, or telematics devices may carry their own warranties. If a vehicle electrical fault is tied to an aftermarket installation, the dealer may attribute the fault to the aftermarket work, potentially limiting coverage for that specific problem.
Protecting your warranty when adding aftermarket parts
To minimize the risk of coverage disputes, consider these best practices before and after installing aftermarket parts:
- Keep all original parts and obtain detailed receipts and installation records from qualified technicians.
- Choose reputable brands and have aftermarket parts installed by trained professionals who can provide verification of proper installation.
- Check whether the parts are Subaru-approved accessories or from a recognized aftermarket provider, and verify any warranty implications with your dealer beforehand.
- Document all maintenance and repairs, including service at authorized Subaru service centers.
- If possible, inform the service advisor about any aftermarket changes before diagnosing a problem so they can isolate potential causes.
Conclusion: Thoughtful planning and thorough documentation can help protect warranty coverage while allowing you to customize your vehicle responsibly.
What to do if a warranty claim is denied because of aftermarket parts
If a claim is denied on the basis of aftermarket parts, you can take several steps to pursue a resolution:
- Request a written explanation detailing how the aftermarket part caused the issue and how the denial aligns with warranty terms.
- Submit evidence showing that the defect is unrelated to the modification, or that installation was performed correctly and within spec.
- Consult the Subaru customer care center or regional office for guidance and potential escalation.
- Consider a second diagnostic opinion from an independent, qualified technician if you disagree with the dealership’s assessment.
- Be aware of state consumer-protection rights and, if necessary, seek guidance from a consumer protection agency or legal counsel.
Conclusion: Denied claims can often be reviewed or resolved through documentation, official channels, and, if needed, independent second opinions.
Summary
Overall, aftermarket parts do not automatically void Subaru’s warranty. The key concept is causal linkage: a problem that stems from the aftermarket modification may not be covered, while unrelated defects typically remain eligible for warranty service. Always document installations and maintenance, work with qualified installers, and consult your dealer or Subaru customer service if you have questions about how a specific modification may affect warranty coverage. Staying informed and prepared helps balance the desire for customization with the protections of your vehicle’s warranty.
What voids the warranty on a Subaru?
Subaru has the right to deny warranty coverage if your vehicle has not been properly maintained, or if repairs are needed because parts other than Genuine Subaru Parts were used. Warranty coverage will be based on component failure, and not just maintenance records alone.
Does installing aftermarket parts void the warranty?
No, installing aftermarket parts does not automatically void your warranty, but it can void the warranty for specific repairs if the part caused the failure. The Magnuson-Moss Warranty Act protects consumers by requiring manufacturers to prove that an aftermarket part directly caused the issue before they can deny a warranty claim for that part. For example, if you install aftermarket speakers, the warranty on your engine is likely to remain valid, but if a performance part like a turbocharger fails, the manufacturer can deny the warranty claim for the engine if they can prove the turbo caused the failure.
How to manage potential warranty issues with aftermarket parts
- Understand the law: The Magnuson-Moss Warranty Act prevents manufacturers from voiding your entire warranty simply for using aftermarket parts.
- Identify the link: If a part fails, the manufacturer must prove that your aftermarket part was the cause of the problem. They cannot deny a warranty claim for an unrelated issue.
- Know the risks: Be aware that performance-enhancing or non-standard modifications can put extra stress on other components. This makes it more likely for a manufacturer to deny a claim if a related part fails.
- Keep records: When you install parts, keep all receipts and records to document the installation. This can be helpful if you need to prove you used quality parts.
- Seek professional advice: If a dealer denies a warranty claim, ask for a written explanation. If you believe the denial is wrongful, you can contact the manufacturer or file a complaint with a consumer protection agency like the FTC.
What is the difference between OEM and aftermarket Subaru parts?
OEM parts are made by the same manufacturer who made the vehicle - in our case, Subaru of America. OEM parts are specifically designed for Subaru models, which means they're a perfect fit for your Subaru SUV. Contrarily, aftermarket parts are designed by an entity other than the automaker.
What modifications void the Subaru warranty?
If you want to make customizations or add accessories, you must be sure to use genuine Subaru parts. If you install aftermarket components that interfere with original parts or cause damage, your warranty can be voided. The same is true if you modify the engine or suspension system.
