The Impact of Vehicle Modifications on Your Lemon Law Claim



Vehicle modifications, while popular among car enthusiasts for enhancing performance and aesthetics, can have significant implications for your lemon law claim. Understanding how these modifications might affect your legal standing is crucial if you find yourself dealing with a faulty vehicle. This blog will explore the potential impact of vehicle modifications on your lemon law claim and provide guidance on navigating these complexities.


Understanding Lemon Law

Lemon laws are designed to protect consumers who purchase or lease defective vehicles. In California, the Song-Beverly Consumer Warranty Act mandates that if a vehicle cannot be repaired after a reasonable number of attempts, the manufacturer must either replace the vehicle or refund the purchase price. Typically, these laws cover defects that impair the use, value, or safety of the vehicle and occur within a certain period or mileage.


Types of Vehicle Modifications

Vehicle modifications come in various forms, including:

  • Performance Enhancements: Engine tuning, turbochargers, and exhaust system modifications.

  • Aesthetic Modifications: Paint jobs, body kits, and custom interiors.

  • Functional Upgrades: Suspension lifts, aftermarket wheels, and advanced audio systems.

While these modifications can personalize and improve your vehicle, they can also complicate a lemon law claim.


How Modifications Can Impact Your Lemon Law Claim

According to the experienced lemon law attorneys at Young & Young APC, there are many reasons that car modifications can negatively impact your lemon law claim:


Warranty Voiding

One of the primary concerns with vehicle modifications is the potential to void the manufacturer's warranty. Most lemon law claims rely on the presence of a valid warranty.

  • Warranty Terms: Modifications that alter the vehicle significantly may void parts or all of the warranty if the manufacturer determines that they have contributed to the defect.

  • Manufacturer Stance: Some manufacturers have strict policies regarding modifications, enforcing warranty voids even for changes not directly related to the defect.


Causation Issues

Proving that the defect existed independently of any modifications is crucial.

  • Burden of Proof: You must demonstrate that the modification did not cause or exacerbate the defect. This can be challenging and often requires expert testimony.

  • Inspection Reports: Detailed pre-modification inspection reports can serve as evidence to support your claim that the defect was not linked to the modification.


Legal Interpretations

Courts may interpret the impact of modifications differently.

  • Case Precedents: Previous cases and jurisdiction-specific interpretations can influence the outcome of your claim.

  • Expert Opinions: Legal experts specializing in lemon law can provide insights into how modifications might be viewed in the context of your claim.


Steps to Take If Your Vehicle Is Modified

California Lemon Laws give you the right as the consumer to file a lemon law claim for your vehicle.  You should take the following steps if your vehicle appears to be a lemon and is modified:


Review Your Warranty

Before making any modifications, carefully review your vehicle’s warranty terms and conditions. Look for clauses related to alterations and modifications.


Document Everything

Keep detailed records of all modifications, including receipts, professional installation documentation, and before-and-after photographs.


Be Prepared for Possible Challenges

Understand that proving your case might be more difficult and be prepared to face additional scrutiny.

  • Expert Witnesses: Prepare to hire automotive experts who can testify that the modifications did not cause the defect.

  • Increased Legal Costs: Be aware that the complexity of your case may lead to higher legal expenses.


Consider Reversing Modifications

If applicable and feasible, reverting your vehicle to its original state can sometimes strengthen your claim.


While vehicle modifications can enhance your driving experience, they can also complicate your lemon law claim. By understanding the potential impacts and taking proactive steps, you can better navigate the legal landscape. Always consult with a knowledgeable lemon law attorney to ensure that your rights are protected and you are well-informed about the implications of your modifications.
