Can You File a Lemon Law Claim if You Modified Your Vehicle in California?

Modifying your car can be a great way to enhance performance, personalization, or simply make driving more enjoyable. But what happens when that customized vehicle turns out to be a lemon? If you’re dealing with repeated repairs, mechanical defects, or serious safety issues, you might wonder whether your modifications have voided your rights under California’s Lemon Law. Whether you’re a car enthusiast or just trying to fix a frustrating problem, here’s what you need to know about filing a Lemon Law claim with a modified vehicle in California.

California’s Lemon Law and Vehicle Modifications

California’s Lemon Law, also known as the Song-Beverly Consumer Warranty Act, protects people who buy or lease a vehicle that turns out to be a lemon. If a manufacturer or dealership can’t fix a major problem with the vehicle after a reasonable number of attempts, you may be eligible for a refund or a replacement vehicle.

However, things can change if your vehicle has been modified—whether for more power, a better look or more functionality. Modifications can complicate things when you’re trying to make a Lemon Law claim. You need to understand how these changes affect your rights and what you can do to protect yourself.

How Modifications Affect Your Lemon Law Claim

1. Warranty Coverage

Modifying your vehicle doesn’t automatically void your warranty. Under the federal Magnuson-Moss Warranty Act, a manufacturer must prove the modification caused the defect to deny warranty coverage. But if the modification is related to the defective part, the manufacturer can deny the claim.

2. Types of Modifications That May Raise Concerns

• Performance Enhancements: Installing aftermarket turbochargers, superchargers or engine tuning chips can make manufacturers claim these modifications caused engine or transmission problems.
• Suspension Alterations: Lift kits or lowered suspensions can be blamed for steering or alignment issues.
• Electrical System Changes: Adding custom audio systems or lighting can complicate electrical problems.

3. Documentation is Key

Keep records of all modifications, including receipts, installation details and any communications with installers. This documentation can prove the modifications were done professionally and not related to the defect.

What to Do After Modifying Your Vehicle

1. Consult the Manufacturer or Dealer Before Modifying

Before making any modifications, consult your vehicle’s manufacturer or authorized dealer. They can tell you how certain changes will affect your warranty.

2. Use Certified Professionals for Modifications

Having modifications done by certified professionals can help your claim that the changes were done properly and not the cause of the defect.

3. Keep Detailed Records

Document everything about your vehicle’s maintenance and modifications. This includes:

• Dates and descriptions of modifications
• Installation receipts
• Correspondence with installers or manufacturers
• Service and repair records

4. Seek Legal Advice Early

If you think your vehicle is a lemon, contact a Lemon Law attorney right away. An experienced attorney can determine if your modifications affect your claim and walk you through the process.
