Lemon Law Attorneys Discuss: The Role of State Regulations

When your car spends more time in the shop than in your driveway, it’s natural to ask what your rights are and who sets the rules. Lemon law protections come from state statutes, and in California those rules are both detailed and consumer-friendly. Below, ZapLemon’s lemon law attorneys discuss how state regulations—and California’s Song-Beverly Consumer Warranty Act in particular—shape defective vehicle claims.

Why State Rules Matter in California Lemon Cases

Every state writes its own lemon law, so a “lemon” in one state can be treated differently in another. California’s lemon law standards define when a manufacturer must buy back or replace a vehicle, what counts as a “reasonable number” of repair attempts, and what types of warranties trigger coverage. Federal warranty law (the Magnuson-Moss Warranty Act) also exists, but California’s state-specific protections often go further and are usually the main driver of relief for in-state consumers.

State rules determine the nuts and bolts: how many repair visits may be enough, whether days out of service count toward a claim, and whether leased or used vehicles are covered. In California, coverage typically hinges on defects that substantially impair use, value, or safety and that occur under the manufacturer’s warranty. Many used cars are included if they were sold with a written warranty—such as a Certified Pre-Owned warranty—while truly “as-is” sales are generally not.

California’s rules also affect where and how you pursue a claim. Issues like whether the vehicle was purchased or registered in California, whether repairs were attempted at authorized dealers, and how quickly you notified the manufacturer can all matter. Practical steps help no matter what: keep copies of every repair order, note dates and mileage, confirm your warranty start date, and save emails or texts with the dealer or manufacturer. While this information is not legal advice, it can help you understand the landscape before you consult an attorney.

How California’s Song-Beverly Act Shapes Claims

California’s Song-Beverly Consumer Warranty Act is the core lemon law for cars and trucks. It requires manufacturers to repurchase or replace a vehicle when a covered defect cannot be fixed after a reasonable number of warranty repair attempts and the issue substantially impairs use, value, or safety. The law also allows recovery of certain incidental expenses tied to the defect, such as towing or rental costs, when supported by documentation.

Song-Beverly includes a helpful presumption during the first 18 months or 18,000 miles (whichever comes first): a vehicle may be presumed a lemon if, for example, the manufacturer or dealer made multiple repair attempts for the same problem, two or more attempts for a defect likely to cause serious injury or death, or the vehicle was out of service for a cumulative 30 days. These are not strict thresholds—claims can still succeed without meeting the presumption, and meeting it doesn’t guarantee an outcome—but they offer a useful guidepost. Either way, each service visit counts as a repair attempt only if the vehicle was presented for warranty service and you have documentation.

Real-world examples help. Recurring transmission shudder or hesitation, brake or steering failures, electrical shorts that drain the battery, stalling engines, malfunctioning airbags, and EV charging or range faults can all be serious enough to trigger rights when they persist under warranty. Tip: ask every service advisor to write your exact complaint in your words on the repair order, verify dates in and out, and check that mileage is accurate. If problems continue, many manufacturers require that you notify them directly, so keep records of calls, emails, or case numbers.
