Ongoing car problems can drain your time, money, and patience—especially when the vehicle is still under warranty. California’s Buyback Lemon Law (part of the Song-Beverly Consumer Warranty Act) is designed to protect you when a manufacturer can’t fix a substantial defect after a “reasonable number” of repair attempts. But what does “reasonable” mean, and how many trips to the shop are enough in California?
How Many Repair Attempts Count Under California Law
California’s lemon law focuses on whether the manufacturer had a reasonable number of chances to fix a substantial defect under warranty. In plain terms, if your car has a problem that significantly impairs its use, value, or safety, the manufacturer must be given an opportunity to repair it at an authorized dealership. If they can’t fix it after a reasonable number of tries, the law may require a buyback or replacement—though whether a buyback is appropriate depends on the facts of your situation and applicable law.
California also has a helpful guideline called the “lemon law presumption” (sometimes called the Tanner presumption). It applies during the first 18 months or 18,000 miles—whichever comes first—and says a vehicle is presumed to be a lemon if any of the following occur: (1) the dealer tried to repair the same problem at least four times; or (2) the dealer tried to repair a defect that could cause death or serious bodily injury at least two times; or (3) the vehicle has been out of service for repair for more than 30 cumulative days. These are not hard caps or guarantees—they are benchmarks that shift the burden of proof and can help your claim.
Even if your situation falls outside the 18 months/18,000 miles window or doesn’t meet the exact numbers above, you may still have a claim under the broader “reasonable attempts” standard. What counts as reasonable depends on the defect, the repair history, and how the issue affects use, value, or safety. Practical steps help: keep every repair order and invoice, note mileage and dates, describe the symptoms consistently (e.g., “transmission hesitates from 1st to 2nd,” “engine stalls at stoplights”), and always take the vehicle to an authorized dealer while the warranty is active. If you’re unsure where you stand, a tailored consultation can clarify next steps.
Safety Defects: Fewer Attempts May Be Required
When a defect risks serious injury—think brake failures, steering loss, fuel leaks, repeated airbag warnings, or sudden engine shutdowns—California law recognizes that fewer repair attempts may be reasonable. Under the presumption, two unsuccessful attempts to fix a life-threatening safety defect within the first 18 months/18,000 miles can be enough to trigger the presumption that the car is a lemon. The bigger picture still matters: severity, recurrence, and the manufacturer’s ability to actually fix the problem are all considered.
If you’re dealing with a safety issue, prioritize safety first: don’t drive the vehicle if it feels dangerous. Have it towed to an authorized dealer and clearly explain the safety symptoms (“brakes fade on downhill,” “steering locks intermittently,” “burning fuel smell under rear seat”). Ask the service advisor to road-test with you, request that all diagnostic codes and test results are attached to the repair order, and get a copy of every document before you leave—even if the shop “cannot duplicate” the issue that day.
Documentation is key for safety-related defects. Track every visit and day the car is out of service, save photos or videos of symptoms, and note tow receipts. Check for recalls and Technical Service Bulletins (TSBs) related to your issue, and consider sending written notice to the manufacturer (certified mail helps create a paper trail) asking for a final repair opportunity. If the defect persists, consulting a lemon law professional can help you understand your options under California Buyback Lemon Law without making any decisions prematurely.
Understanding how many repair attempts are “enough” in California often comes down to the details: the nature of the defect, timing, and your repair history.
