California Lemon Law: Repair Attempt Thresholds

If your car keeps going back to the shop for the same problem, you’ve probably started searching for California Lemon Law information—especially the “repair attempt thresholds” that trigger legal protections. In California, the Song-Beverly Consumer Warranty Act (often called the California Lemon Law) provides powerful remedies when a manufacturer can’t fix a covered defect after a reasonable number of tries. Below, we explain what those thresholds are, how they work, and practical steps you can take to protect your rights.

What Are California’s Repair Attempt Thresholds?

California has a legal “presumption” that helps consumers prove a vehicle is a lemon when certain repair attempt thresholds are met within the first 18 months or 18,000 miles, whichever comes first. This presumption is part of California’s Tanner Consumer Protection Act, which operates within the broader Song-Beverly Consumer Warranty Act. If the presumption applies, it shifts some of the legal burden to the manufacturer, making your claim easier to pursue.

The key thresholds are: (1) four or more repair attempts for the same defect, (2) two or more repair attempts for a defect that could cause death or serious bodily injury if the vehicle is driven, or (3) the vehicle is out of service for repair for a total of 30 or more cumulative days. These are not hard limits on your rights—rather, they are landmarks that, if met, make it easier to show the manufacturer had a reasonable opportunity to fix the issue and failed.

Importantly, your case is not automatically lost if you’re outside the 18-month/18,000-mile window or if you haven’t hit these exact numbers. The law still protects you if a substantial defect covered by the warranty hasn’t been fixed after a reasonable number of attempts. The presumption just provides a helpful shortcut. Coverage can also extend to certain used vehicles still under the manufacturer’s warranty, and some small-business vehicles, depending on weight and fleet size limits. A consultation can clarify how the rules apply to your situation.

How Many Repair Attempts or Days Out of Service?

Think of “repair attempts” as documented visits where you reported the same defect and the dealer tried to fix it under warranty. For example, if your car stalls at highway speeds and you’ve brought it in three separate times for the same stalling concern, that’s three repair attempts. If the issue is safety-related—like an airbag warning that can’t be resolved or a brake failure—the two-attempt safety threshold may be relevant. Always make sure your repair order states your complaint in your own words (e.g., “vehicle stalls while merging,” “airbag light remains on”).

“Days out of service” are the calendar days your vehicle is unavailable to you because it’s at the dealer for warranty repairs—even if those days are non-consecutive. If your car spends 12 days at the shop for a transmission issue in January and 20 days in March for the same or another covered defect, that’s 32 cumulative days out of service. Routine maintenance doesn’t count, and delays caused by you (like declining a repair) may not count either, but parts wait time, diagnosis, and test-driving days usually do.

Another detail: To use the presumption, many warranties require that you give the manufacturer direct written notice and an opportunity to repair. The process is often outlined in your warranty booklet. Even if you don’t use the presumption, notifying the manufacturer and keeping thorough records strengthens your claim. Practical tips include: keep every repair order and invoice, jot down dates/mileage/symptoms, take photos or videos when possible, and ask the service advisor to list the specific concern and what was done each visit.
