If your new or certified used car keeps going back to the shop for the same issue, you’re probably wondering how California’s Lemon Law applies and what you can reasonably expect from the repair process. Below, we explain how the California Lemon Act frames your repair rights, what “reasonable attempts” mean in plain English, and practical steps for tracking timelines, work orders, and warranty coverage. This article is for general information only and isn’t legal advice; every situation is unique, so consider speaking with a professional about your specific facts.
California Lemon Act: What to Expect in Repairs
California’s Lemon Law—part of the Song-Beverly Consumer Warranty Act—generally requires manufacturers to repair defects that are covered by warranty and that substantially impair the use, value, or safety of the vehicle. In everyday terms, if your car has a serious recurring problem while under warranty, the manufacturer must be given a fair chance to fix it at an authorized facility at no charge to you for parts and labor. Examples include a transmission that slips under normal driving, repeated stalling, brake system warnings, electrical failures that cause the car not to start, or safety tech malfunctions such as failing airbags or backup cameras.
The law also includes what’s commonly called the “Tanner presumption.” Under that presumption, a vehicle may be presumed a lemon if, within the first 18 months or 18,000 miles (whichever comes first), certain thresholds are met—such as two or more repair attempts for a defect that could cause serious injury or death, four or more attempts for other persistent issues, or the car being out of service for 30 or more cumulative days for covered repairs. This presumption is not the only path to a claim, and exceptions apply; not meeting these numbers doesn’t automatically mean you’re out of options, and meeting them doesn’t automatically guarantee a buyback.
During repairs, you can generally expect the dealership to diagnose and attempt to correct the defect, to document the work in a repair order, and to return the vehicle when they believe the issue is resolved. If the dealer needs the car for multiple days, ask whether your warranty or the manufacturer offers rental or loaner coverage. Keep communication professional and detailed: describe symptoms (what you felt, heard, or saw), when they occur (speed, temperature, terrain), and how often they appear, so the technician has the best chance of reproducing the problem.
Tracking Attempts, Timelines, and Warranty Steps
Good records are your best friend. Each time you visit the dealer, ask for a copy of the repair order when you drop off the car and the final invoice when you pick it up. Verify that the paperwork lists your complaint in your own words, the technician’s findings, the parts replaced or software updates applied, the dates in and out, and the mileage in and out. If the problem comes back, note when it happens and under what conditions (for example, “shudders between 25–35 mph after 15 minutes of driving” or “check engine light after cold start”), and bring that note with you.
Timeline tracking matters because California’s Lemon Law focuses on a “reasonable number” of repair attempts and days out of service. If you’re approaching multiple visits for the same defect or piling up weeks in the shop for warranty repairs, your file of dated paperwork helps show patterns. Many consumers keep a simple log with columns for date, dealer, mileage, complaint, and outcome; they also save texts or emails with the service advisor and any receipts for towing or rentals tied to a warranty issue.
Before, during, and after repairs, check your warranty booklet for coverage details, required procedures, and any manufacturer dispute programs. In many cases, you’ll start with the selling or servicing dealer, but you can also contact the manufacturer’s customer care line to open a case number if repairs repeat. Some consumers choose to send written notice to the manufacturer about ongoing nonconformities; others explore arbitration programs listed in the warranty materials. Which step makes sense depends on your situation, and a consultation can help you understand options without making promises about results.
