If your car keeps spending time at the dealership instead of your driveway, you’re probably wondering how many “days in the shop” it takes before California’s Lemon Law kicks in—and what a buyback might actually look like. Below, we explain in plain English how the “days in the shop” rule works under California’s Lemon Law and what consumers can expect from a potential manufacturer buyback. This article is informational and aims to help you spot issues, organize your records, and understand your options before you speak with a professional.
How ‘Days in the Shop’ Trigger California Lemon Law
California’s Lemon Law (part of the Song-Beverly Consumer Warranty Act) looks at both the number of repair attempts and the total days your vehicle is out of service for warranty repairs. A common benchmark—sometimes called the “Tanner presumption”—is reached if, during the first 18 months or 18,000 miles after delivery, (1) the dealer has tried to fix the same problem four or more times, (2) they’ve tried twice to fix a defect that could cause serious injury or death, or (3) your vehicle has been out of service for more than 30 cumulative calendar days for warranty repairs. Those 30 days don’t have to be consecutive, and weekends can count if the car remains unavailable due to repair.
“Days in the shop” usually means days when the vehicle is at an authorized facility or otherwise unavailable to you because it’s awaiting diagnosis, parts, or completion of a warranty repair. For example, if your SUV spent 12 days for a transmission issue, 8 days for an electrical problem, and 11 days for a recurring check-engine light during the covered period, that’s 31 total days out of service—enough to satisfy the presumption. Even if you received a loaner or rental during repairs, your vehicle’s days out of service can still count toward the total.
It’s also important to know that you may have a valid Lemon Law claim even if you don’t meet the presumption numbers exactly. The presumption simply makes it easier to prove your case; it is not the only pathway. Whatever your situation, document everything: keep every repair order, warranty invoice, and tow receipt, and note dates the car was dropped off and picked up. Clear records help show how many days the vehicle was down and what the dealership tried to fix, and they can be critical in any buyback discussion.
California Buyback Basics: Rights and Next Steps
When a manufacturer agrees (or is ordered) to repurchase a vehicle under California’s Lemon Law, it’s commonly called a “buyback.” In a typical buyback, the manufacturer refunds what you paid or owe for the vehicle (such as the down payment, monthly payments made, and certain taxes and fees), pays off the remaining loan if applicable, and may reimburse reasonable incidental costs tied to the defect (like towing or rental cars). California law generally allows the manufacturer a “mileage offset” for the use you had before the first repair attempt for the defect—so the final refund is adjusted based on mileage at the first repair visit.
A buyback isn’t the only remedy; a manufacturer may also offer a replacement vehicle. Whether a buyback or replacement makes sense depends on your circumstances, warranty coverage, and the nature of the defects. Keep in mind that every case is fact-specific, and outcomes vary. That’s why it helps to get a personalized evaluation before you decide how to proceed.
Practical next steps include continuing to take your vehicle to an authorized dealer for warranty repairs, describing symptoms clearly, and asking for detailed repair orders each time (with dates, mileage, and the technician’s notes). Organize your timeline of visits and days out of service, and keep receipts for related expenses. If you think you may be approaching the “30 days in the shop” mark or have multiple repair attempts for the same issue, consider speaking with a professional to understand your rights and options before contacting the manufacturer about a repurchase or replacement.
