California Lemon Law and Manufacturer Obligations

If your new or used car in California keeps going back to the shop for the same problem, you’re probably wondering whether it qualifies as a “lemon” and what the manufacturer must do about it. This overview explains the basics of California Lemon Law and manufacturer obligations in clear, everyday terms so you can understand your options, keep good records, and know when to take the next step. This is general information, not legal advice.

California Lemon Law: What Qualifies as a Lemon?

California’s Lemon Law—part of the Song-Beverly Consumer Warranty Act—generally applies to vehicles sold or leased in California that are still under the manufacturer’s warranty. In simple terms, a “lemon” is a vehicle with a defect (or “nonconformity”) that substantially impairs the car’s use, value, or safety, and the manufacturer or its authorized dealer can’t fix it after a reasonable number of attempts. The law typically covers passenger cars, SUVs, and light trucks, and may also cover certain business vehicles, depending on their weight and use.

A common question is how many repairs are “reasonable.” California’s Lemon Law includes a helpful “presumption” during the first 18 months or 18,000 miles: two or more attempts for a defect that can cause serious injury or death (such as brake or steering failures), four or more attempts for the same recurring problem (like stalling, transmission shudder, or persistent check-engine warnings), or 30+ cumulative days out of service for warranty repairs may trigger the presumption. Importantly, you can still qualify outside that window or without meeting those exact numbers—what matters is the pattern of defects and repair attempts under warranty.

Practical steps can strengthen your position: keep every repair order, note the mileage and dates, and track how many days your car is in the shop. Be specific when describing symptoms (e.g., “vehicle hesitates on acceleration at 25–35 mph,” “backup camera screen goes black intermittently”). Ask the dealer to include your concerns on the repair paperwork, save towing or rental receipts, and check for recalls or technical service bulletins (TSBs). Clear, consistent documentation helps show that the problem is real, recurring, and covered by warranty.

Manufacturer Obligations: Warranties and Repairs

Manufacturers provide express warranties that promise to repair defects in materials or workmanship within a certain time or mileage. California law also recognizes implied warranties, such as the implied warranty of merchantability, which generally means the vehicle should be fit for ordinary driving. The exact terms and duration of warranties can vary, and some may be limited by the manufacturer—so it’s important to read your warranty booklet and understand what is and isn’t covered.

During the warranty period, the manufacturer must authorize and pay for necessary repairs to correct covered defects within a reasonable time. Repairs are typically performed at authorized dealerships, and you shouldn’t be charged for covered diagnostics or parts and labor. If a part is on backorder or the dealership needs multiple visits to diagnose an intermittent issue, continue to bring the vehicle in so there’s a documented trail of efforts to fix the problem. If transportation is an issue, ask about loaners or rental coverage; some programs offer them, though availability can vary.

If the manufacturer cannot repair a defect after a reasonable number of attempts, California Lemon Law may require a repurchase (buyback) or replacement. A buyback usually includes your vehicle’s price and certain incidental costs, minus a mileage offset based on when the defect first appeared; a replacement would involve a substantially similar new vehicle. Some manufacturers have voluntary dispute resolution or arbitration programs, which can be one path to resolution. Because details matter—timelines, repair counts, documentation—consumers often benefit from reviewing their situation with a knowledgeable lemon law team.
