California Car Lemon Law When Repairs Keep Failing

When your car keeps going back to the shop for the same problem, it’s frustrating, time-consuming, and potentially dangerous. California’s Lemon Law—part of the Song-Beverly Consumer Warranty Act—exists to protect consumers dealing with repeated, unsuccessful repair attempts. This article explains the basics in plain language, so you can understand how the law works when repairs keep failing and what might indicate that your vehicle qualifies as a “lemon.”

When Repairs Keep Failing: California Lemon Basics

If your vehicle is still under the manufacturer’s warranty and the dealer can’t fix a substantial problem after multiple attempts, California’s Lemon Law may apply. “Substantial” generally means the defect affects the car’s use, value, or safety. Think of issues like stalling while driving, transmission slipping or shuddering, recurring check-engine lights linked to drivability, brake failures, steering defects, or electrical problems that disable important functions. Minor annoyances—like a loose trim piece—usually won’t qualify, but problems that keep you from reliably using your car or that create safety risks are the focus.

A key concept is a “reasonable number of repair attempts.” There isn’t a single number that automatically wins every case, but the law provides helpful guideposts. For many defects, four or more attempts to fix the same problem can be considered reasonable. For serious safety issues—like brake or airbag failures—two attempts may be enough. Another marker is total time the car is out of service: if your vehicle spends 30 or more cumulative days in the shop for warranty repairs, that can also support a claim. The repairs must start while the vehicle is under warranty, and you typically need to give the manufacturer/dealer a fair chance to fix the problem.

While you’re dealing with repeat repairs, there are practical steps you can take. Always bring the car to an authorized dealership for warranty work and describe the issue the same way each time so it’s clearly documented as the “same” defect. Keep every repair order and invoice, note the dates the car is in the shop, and save any emails or texts with the service department. Review your warranty booklet to follow any required steps, and consider sending written notice to the manufacturer when problems persist. These records can make a big difference if you later pursue a lemon claim.

What Counts as a Lemon Under CA’s Song-Beverly

California’s Song-Beverly Consumer Warranty Act covers many new and used vehicles that are sold or leased with a manufacturer’s warranty. This includes most passenger cars, SUVs, vans, and light trucks purchased or leased in California. Used vehicles can qualify if they’re still within the original manufacturer’s warranty period (or a certified pre-owned warranty). Some small-business vehicles may also be covered under certain weight and fleet-size limits. If in doubt, check your warranty and registration documents and talk with a professional about eligibility.

Within the first 18 months or 18,000 miles (whichever comes first), the law creates a helpful presumption: your car may be presumed a lemon if either (1) the same problem has been subject to repair four or more times, (2) a defect that could cause death or serious injury has been subject to repair two or more times, or (3) the vehicle has been out of service for repairs for a total of 30 or more days. This presumption isn’t the only way to prove a lemon case—cars outside those time or mileage windows can still qualify—but it provides a strong starting point. The defect must be covered by the warranty and not caused by misuse or unauthorized modifications.

If your vehicle qualifies, the manufacturer generally must offer a replacement or a repurchase (often called a “buyback”). A repurchase typically includes refunding the price you paid (including certain taxes and fees), minus a mileage offset for the use you had before the first repair attempt for the defect. The offset is calculated using a statutory formula based on the miles at the first repair. Replacement vehicles must be substantially identical and come with a new warranty. Every situation is unique, deadlines may apply, and manufacturers sometimes offer arbitration, so it’s wise to get a consultation to understand your options before making decisions.
