If your new vehicle keeps returning from the dealership with the same unfixed problem, California’s lemon law may entitle you to a buyback. But how much you actually receive comes down to a specific, statute-driven formula — and manufacturers don’t always calculate it in your favor. Here’s exactly what a lemon law buyback is, what it must include, and how the refund amount is determined.
Quick answer: A California lemon law buyback is a manufacturer repurchase of your defective vehicle. You get back nearly everything you paid — purchase price, taxes, fees, and related costs — minus one permitted deduction: a mileage offset based on how far you drove before the first repair attempt. The formula is (miles at first repair ÷ 120,000) × purchase price.
What is a lemon law buyback?
A buyback (also called a repurchase) is one of two remedies the manufacturer owes under California’s Song-Beverly Consumer Warranty Act when it can’t fix a covered defect within a reasonable number of attempts. The other option is a replacement vehicle. A buyback isn’t a goodwill gesture — it’s a statutory obligation, and most consumers choose it.
In practice, a buyback unwinds the purchase: you return the defective vehicle, and the manufacturer returns most of what you put into it. Unlike a trade-in or private sale, you are not penalized for the lost market value the defect caused. The first question is simply whether your vehicle qualifies as a lemon.
What a lemon law buyback must include
Under Civil Code §1793.2, a compliant buyback is far more than the sticker price. It must reimburse the full financial impact of the defective vehicle, including:
- The actual price you paid — vehicle price plus sales tax, license and registration fees, and any manufacturer-installed options. This is what you paid, not a depreciated or market value.
- What you’ve paid toward financing — your down payment, monthly payments made, and the outstanding loan payoff.
- Incidental and consequential costs caused by the defect — towing, rental cars, and other reasonable out-of-pocket expenses.
If you leased the vehicle, the math is similar but based on your lease payments and down payment rather than a purchase price.
The one deduction: the mileage (usage) offset
The only deduction California law allows is the mileage offset — sometimes called the usage offset — set by Civil Code §1793.2(d)(2)(C):
Mileage offset = (miles at first repair attempt ÷ 120,000) × purchase price
The 120,000 figure is the useful life California law presumes for every vehicle. It’s fixed — it does not change based on make, model, or vehicle type. If a manufacturer claims it uses 100,000 or 80,000 “because it’s a luxury car or an EV,” that is not California law.
As an illustration: if you paid $40,000 and first brought the vehicle in for the defect at 6,000 miles, the offset is (6,000 ÷ 120,000) × $40,000 = $2,000. That $2,000 is subtracted from your refund.
The detail that matters most: the miles that count are the miles at your first repair attempt for the defect — not the mileage when the buyback happens, and not your total miles driven. Miles you accumulate afterward, including during months of failed repair attempts, do not increase the deduction. You can see where this falls in the lemon law process.
How manufacturers undervalue buybacks
Because most claims resolve through negotiation, the buyback figure is the heart of the deal — and that’s where manufacturers routinely shortchange consumers who don’t know the law. Common tactics include:
- Calculating the offset on current mileage instead of mileage at the first repair attempt.
- Quoting a lower “purchase price” that leaves out tax, fees, or installed options.
- Omitting incidental costs like rentals and towing.
- Deducting items the statute simply doesn’t permit.
If you receive an offer with unexplained deductions, ask for a line-by-line calculation. Small errors can cost thousands of dollars.
Civil penalties can add to your recovery
If the manufacturer’s failure to comply was willful, California law allows a civil penalty of up to two times your actual damages under Civil Code §1794(c). Importantly, that penalty is measured against your damages and is not reduced by the mileage offset — for the right case, it can exceed the offset many times over.
You don’t pay attorney’s fees out of your buyback
Song-Beverly shifts your reasonable attorney’s fees and costs onto the manufacturer when you prevail. That means a qualified lemon law firm can review the numbers and pursue your claim at no out-of-pocket cost to you — you keep your buyback. You can see the kinds of outcomes that follow on our case results page.
How to protect your buyback amount
Save every repair order and dealership invoice, and note the mileage and date of each visit — especially your first defect-related visit, since that mileage controls the offset. Keep rental and towing receipts too. Before you accept any offer, have an attorney check the math against the statute. For a fuller walkthrough, see our California lemon law buyback guide.
