Automobile Lemon Law California: Frequently Asked Questions for California Consumers

If your car keeps spending more time in the shop than in your driveway, you’re not alone. Many California drivers search for answers about the Automobile Lemon Law in California when ongoing defects won’t go away. This FAQ-style guide from ZapLemon explains key concepts in plain English so you can understand your rights, what “reasonable repair attempts” means, and what steps you can take next—without legal jargon.

What Is California’s Lemon Law for Vehicles?

California’s Lemon Law is part of the Song-Beverly Consumer Warranty Act. In simple terms, it says that if a manufacturer can’t fix a warranty-covered defect that substantially impairs the vehicle’s use, value, or safety after a reasonable number of attempts, the consumer may be entitled to a refund (buyback) or a replacement. The law generally applies to new vehicles and many used vehicles that are still under the manufacturer’s new-car warranty, as well as certain certified pre-owned vehicles. It covers cars, trucks, SUVs, vans, and often some small business vehicles used primarily in California.

To qualify, the defect usually must arise during the warranty period and be covered by the manufacturer’s warranty. “Substantially impairs” doesn’t require the car to be undrivable—issues like repeated transmission shuddering, brake problems, loss of power steering, electrical failures, persistent check-engine warnings, or stalling may qualify if they significantly affect use, value, or safety. If the problem is intermittent, you still have rights; what matters is the defect’s impact and the manufacturer’s opportunity to repair it.

If the law applies, potential remedies can include a repurchase (commonly called a “buyback”) or a replacement vehicle, along with certain incidental damages like towing or rental costs. A usage offset may be applied for miles driven before the first documented repair attempt for the defect. California law may also provide civil penalties in specific situations and fee-shifting so that, if you prevail, the manufacturer may be required to pay your reasonable attorney’s fees. Every case is fact-specific, and outcomes depend on the details.

How Many Repair Attempts Does the Law Require?

California’s Lemon Law does not set a single number for every situation. Instead, it uses a “reasonable number of repair attempts” standard, which depends on the severity and nature of the defect and the history of repairs. As a rule of thumb, keep taking your vehicle to an authorized dealer and make sure your concerns are accurately written on each repair order. Save repair invoices, diagnostic reports, and any communication with the dealer or manufacturer—clear records are essential.

There is also a legal presumption (often called the Tanner presumption) that helps consumers in the first 18 months or 18,000 miles, whichever comes first. Under that presumption, your vehicle may be presumed a lemon if: the manufacturer or dealer made 2 or more repair attempts for a defect that is likely to cause death or serious bodily injury; or 4 or more repair attempts for the same defect; or the vehicle was out of service for repairs for more than 30 total days. Even if you’re outside the 18-month/18,000-mile window, you may still have a claim—the presumption just makes it easier to prove.

Practically speaking, “repair attempts” include each documented visit where you complained about the defect and the dealer tried to fix it, even if parts weren’t available or the condition was intermittent. Days your vehicle sits at the dealership waiting for parts can count toward total days out of service. Helpful tips: bring a written list of symptoms, ask the advisor to include your description on the repair order, keep copies of all paperwork, and check your warranty booklet for any requirements about notifying the manufacturer. If you think your vehicle qualifies or you’re unsure how many attempts are “enough,” consider contacting a lemon law professional to review your records.
