How the Lemon Law Mileage Offset Works in California

What Is the Lemon Law Mileage Offset?

When the manufacturer buys back your defective vehicle under California’s Lemon Law, they’re allowed to deduct a mileage offset from your refund. This deduction compensates the manufacturer for the miles you drove before the vehicle first exhibited the defect.

The logic is simple: you got some use out of the vehicle before problems started, and the mileage offset accounts for that use. However, you only pay for miles driven before the first repair attempt — not for the total miles on the odometer when you return the vehicle.

The Mileage Offset Formula

California Civil Code Section 1793.2(d)(2)(C) defines the mileage offset formula:

Mileage Offset = Purchase Price × (Miles at First Repair ÷ 120,000)

Let’s break this down:

Purchase Price = The actual price you paid for the vehicle (not MSRP, not including tax)
Miles at First Repair = The odometer reading when you first brought the vehicle to the dealer for the defect that makes it a lemon
120,000 = The statutory divisor used in California’s formula

Real-World Examples

Example 1: Low-Mileage Defect

You purchased a $35,000 sedan. At 2,000 miles, the transmission started shuddering and you took it to the dealer.

Offset = $35,000 × (2,000 ÷ 120,000) = $583

Your buyback refund would be $34,417 plus taxes, fees, and incidental costs. That’s a very favorable offset.

Example 2: Mid-Mileage Defect

You purchased a $50,000 SUV. At 15,000 miles, the engine started stalling intermittently.

Offset = $50,000 × (15,000 ÷ 120,000) = $6,250

Your buyback refund would be $43,750 plus taxes, fees, and incidentals.

Example 3: Higher-Mileage Defect

You purchased a $45,000 truck. At 30,000 miles, severe electrical issues appeared.

Offset = $45,000 × (30,000 ÷ 120,000) = $11,250

Your buyback refund would be $33,750 plus taxes, fees, and incidentals.

Example 4: Luxury Vehicle with Early Defect

You purchased a $90,000 luxury vehicle. At 500 miles, the infotainment system stopped working.

Offset = $90,000 × (500 ÷ 120,000) = $375

Your buyback refund would be $89,625 plus taxes, fees, and incidentals.

What Counts as the “First Repair Attempt”?

This is one of the most important — and most contested — elements of the mileage offset calculation. The “first repair attempt” is the date you first brought the vehicle to the dealer for the specific defect that qualifies your vehicle as a lemon.

Key points:

It’s the mileage at your first visit, not when the defect was finally diagnosed
If you reported the problem but the dealer said it was “normal,” that still counts as a repair attempt
If you had multiple defects, the offset is based on the defect you’re using for your claim — typically the one reported earliest
The repair order from this first visit is critical evidence — keep it safe

How to Minimize Your Mileage Offset

1. Report Defects Immediately

The single most important thing you can do is take your vehicle to the dealer as soon as you notice a problem. The earlier you report it, the fewer miles on the odometer, and the smaller the offset.

2. Don’t Wait for the Problem to “Get Worse”

Many consumers wait until a defect becomes severe before visiting the dealer. This is a mistake. Even if the dealer says “we can’t replicate the issue,” that visit is documented and counts as your first repair attempt.

3. Keep Detailed Records

Make sure the dealer records your complaint accurately on the repair order. If they write “customer states transmission shudders” at 3,000 miles, that’s your first repair attempt — even if they didn’t actually fix anything. See our guide on how to document your lemon law case.

4. Dispute Inaccurate Mileage Claims

Manufacturers sometimes try to argue that an earlier defect was a “different problem” to push the first repair attempt date later (and increase the offset). An experienced attorney can challenge these arguments.

What the Mileage Offset Does NOT Deduct

The mileage offset is taken from the purchase price only. It does not reduce your recovery of:

Sales tax — You get back the full sales tax you paid
Registration and license fees — Fully reimbursed
Incidental damages — Towing, rental cars, ride-shares, etc.
Monthly payments — All payments you’ve made on the loan
Loan payoff — The manufacturer pays off any remaining loan balance

Mileage Offset in Lease Situations

For leased vehicles, the mileage offset works differently. Instead of applying the formula to the purchase price, it’s typically applied to the capitalized cost of the lease. The formula is the same, but the base number is different. Consult with an attorney to understand how this affects your specific lease.

Can You Avoid the Mileage Offset Entirely?

In some cases, yes. If you choose a vehicle replacement instead of a buyback, the mileage offset typically does not apply. You receive a new vehicle of comparable value without any mileage deduction.

Alternatively, a cash-and-keep settlement is negotiated separately and doesn’t use the mileage offset formula at all — it’s a negotiated amount based on the diminished value and inconvenience.

Common Questions About the Mileage Offset

What if my defect was present from day one? If the defect existed from delivery (0 miles), your mileage offset would theoretically be $0. In practice, most consumers drive at least a few hundred miles before the defect manifests, but the offset is still minimal.

Does the 120,000 number change? No. The 120,000-mile divisor is set by California statute and applies to all vehicles regardless of expected lifespan.

What if I have multiple defects? Your attorney will typically base the claim on whichever defect was reported earliest to minimize the mileage offset.
