California Lemon Law: Recognizing Repeated Defects

Ongoing car problems can be frustrating, expensive, and time-consuming. If the same issue keeps returning after multiple trips to the shop, you may be dealing with a “repeated defect” under California’s lemon law. This article explains what that term means in plain language, how “repair attempts” are counted, and what steps you can take to document your situation. It’s meant to help you spot the signs early so you can decide whether to speak with a lemon law attorney.

What Counts as a Repeated Defect in California

Under California’s Song-Beverly Consumer Warranty Act (often called the California lemon law), a “repeated defect” is a problem covered by the manufacturer’s warranty that substantially impairs the use, value, or safety of your vehicle—and keeps coming back despite attempts to fix it. Think engine stalling, transmission slipping, brake problems, steering issues, electrical failures, or persistent check-engine lights. Minor annoyances like a loose trim piece usually won’t qualify unless they meaningfully affect use, value, or safety.

California has a helpful shortcut known as the “lemon law presumption.” If, within the first 18 months or 18,000 miles (whichever comes first), the manufacturer or its dealer: (1) tried to repair the same problem four or more times, or (2) tried two or more times to repair a defect that could cause death or serious injury, or (3) kept your vehicle in the shop for warranty repairs for more than 30 total days, the law presumes your car is a lemon. This presumption is not the only path—cars outside those time/mileage limits can still qualify if there were a reasonable number of repair attempts.

The defect must be covered by the manufacturer’s warranty (new vehicle warranty or a remaining/certified pre-owned manufacturer warranty). Used vehicles can also qualify if they’re still under a manufacturer warranty or a dealer-provided warranty. Issues caused by abuse, neglect, unauthorized modifications, or normal wear and tear generally aren’t covered. Intermittent problems still count—if they’re documented and the dealer has had a fair chance to diagnose and repair them.

Repair Attempts, Safety Issues, and Your Records

A “repair attempt” typically means you gave an authorized dealership a chance to diagnose and fix the problem. To make it count, bring the car to an authorized dealer, describe the symptoms clearly, and ensure the concern is written on the repair order in your own words. Ask to test-drive with a technician if the problem is intermittent. Each visit should produce a repair order stating your complaint, the technician’s findings, and what was done. Do not try to fix covered issues yourself—dealer documentation is key.

Safety-related defects are treated more urgently. If your vehicle stalls at highway speed, loses braking power, has steering failures, airbag warnings, fuel leaks, or other conditions that could cause serious injury, the law’s presumption can trigger after as few as two repair attempts in the 18-month/18,000-mile window. If the car feels unsafe, consider towing it rather than driving. Keep notes about when and how the safety issue occurred, and tell the service advisor that you believe the condition is dangerous.

Your records can make or break a lemon claim. Save every repair order, invoice, and warranty printout, along with tow and rental/loaner receipts, emails with the dealer, and photos or videos showing the issue. Keep a simple timeline listing dates, mileage in/out, days the car was in the shop, and the symptoms reported. Check your warranty booklet for coverage terms and any manufacturer contact steps. If the same defect keeps returning, consult a professional to review your documentation and explain your options. ZapLemon can evaluate your situation and help you understand what to do next.
