Not every car problem is just a “bad day.” Some are lemons—and California law gives you the right to do something about it.

If your new (or used) vehicle keeps having serious issues, even after multiple repair attempts, you may be entitled to a refund, replacement, or cash settlement under the California Lemon Law.

What Is the California Lemon Law?

California’s Lemon Law protections are grounded in the Song-Beverly Consumer Warranty Act, with additional provisions under the Tanner Consumer Protection Act specifically aimed at defective vehicles. These rules protect consumers who purchase or lease vehicles that turn out to be defective. It applies to new and certain used vehicles that are still under the manufacturer’s warranty.

If your car has a substantial defect that the dealership or manufacturer can’t fix within a reasonable number of attempts, it may legally qualify as a lemon.

What Actually Makes a Car a Lemon?

There’s no single definition, but California courts look at a few key factors:

1. The Vehicle Has a Significant Problem
The issue must impair the use, value, or safety of the vehicle. This could include:

  • Transmission failures

  • Brake issues

  • Engine stalling

  • Electrical malfunctions

  • Defective airbags or seatbelts

Trivial cosmetic problems usually don’t qualify.

2. The Problem Occurs Within the Warranty Period
The defect must arise while the vehicle is still covered by the original manufacturer’s warranty—not an extended service contract or third-party warranty.

3. You’ve Given the Manufacturer a Fair Chance to Fix It
You must allow the manufacturer or its authorized repair facility a “reasonable number of attempts” to fix the problem. That typically means:

  • 2+ repair attempts for a serious safety issue (e.g., brakes or steering), OR

  • 4+ repair attempts for the same recurring problem, OR

  • 30+ total days out of service for any combination of repairs

You don’t need to meet all three—any one may qualify.

Does the Lemon Law Apply to Used Cars?

Yes, if the used car:

  • Was purchased from a dealership, not a private party

  • Is still covered by the original manufacturer’s warranty (time or mileage)

  • Has a defect that meets the above criteria

Many certified pre-owned (CPO) vehicles also qualify, depending on the terms of the CPO warranty.

3. Don’t Wait Delays can make your case harder.
