If you bought a car that keeps breaking down, California law may require the manufacturer to replace it or give you a full refund.
Buying a vehicle should give you peace of mind, not constant trips to the repair shop. Unfortunately, many California drivers find themselves stuck with cars, trucks, SUVs, or even RVs that repeatedly malfunction despite multiple repair attempts. If this sounds familiar, California's Lemon Law may protect you.
California has some of the strongest consumer protection laws in the country. Under the Song-Beverly Consumer Warranty Act, commonly known as California's Lemon Law, vehicle manufacturers are required to repair defective vehicles. When they cannot fix the problem after a reasonable number of attempts, they may be legally required to replace the vehicle or refund your money.
In 2026, several important updates and deadlines continue to affect lemon law claims, making it more important than ever for consumers to understand their rights.
What Exactly Is a "Lemon"?
A vehicle is generally considered a lemon when:
- It has a serious defect covered under the manufacturer's warranty.
- The defect substantially affects the vehicle's use, value, or safety.
- The manufacturer or authorized dealership cannot fix the issue after a reasonable number of repair attempts.
If your vehicle keeps experiencing the same major problem and nobody can properly repair it, the law may require the manufacturer to make things right.
What Vehicles Are Covered Under California Lemon Law?
Many people assume the law only applies to brand-new cars. That is not entirely true.
Covered vehicles include:
- Cars, pickup trucks, SUVs, and vans
- Dealer-owned demonstrator vehicles
- Certified pre-owned vehicles with active manufacturer warranties
- Certain motorhome components
- Business vehicles under 10,000 pounds
- Vehicles leased in California
Vehicles NOT covered:
- Motorcycles
- Off-road vehicles
- Motorhomes primarily used as living spaces
- Vehicles sold completely "as-is" without a manufacturer warranty
The used car question is one of the most common sources of confusion. A used vehicle may qualify if it is still covered by the manufacturer's original warranty or was sold with a certified pre-owned warranty backed by the manufacturer. Vehicles sold "as-is" with no manufacturer warranty generally fall outside lemon law protections.
What Counts as a "Substantial Defect"?
Not every vehicle problem qualifies under lemon law.
The defect must significantly impact the vehicle's safety, value, reliability, or everyday usability. Minor inconveniences generally do not qualify unless they become persistent and significantly interfere with normal vehicle use.
Engine and Transmission Problems
- Stalling or failure to start
- Sudden loss of power
- Transmission slipping or jerking
Electrical System Failures
- Repeated battery drain
- Malfunctioning electronics or dashboard warning lights that never resolve
- Wiring problems
Safety Defects
- Brake failures or steering problems
- Airbag malfunctions
- Seatbelt defects
Recurring Mechanical and HVAC Issues
- Persistent overheating or fuel system failures
- Defective suspension systems
- Repeated heating or air-conditioning failures, which can become serious safety issues in California's extreme temperatures
Minor cosmetic problems, scratches, rattles, or normal wear and tear generally do not qualify.
How Many Repair Attempts Are Required?
California law does not always require a fixed number of repairs. Courts look at whether the manufacturer had a "reasonable opportunity" to repair the vehicle.
California's Lemon Law Presumption provides guidelines for determining when repair attempts become unreasonable. The presumption applies if any of the following occur within 18 months or 18,000 miles (whichever comes first) from the date of purchase:
- Four or more repair attempts for the same problem.
- Two or more attempts for a defect likely to cause death or serious bodily injury.
- The vehicle is out of service for more than 30 cumulative days for warranty repairs.
A vehicle may still qualify as a lemon even if it does not fit neatly into these categories. Some dangerous safety defects may qualify after only one or two failed repair attempts. Detailed repair records are essential.
Human Verification Required: The Lemon Law Presumption thresholds (18 months/18,000 miles) are based on California Civil Code § 1793.22. Confirm current statutory language with a licensed California attorney, as deadlines and procedures changed in 2025 under AB 1755 and SB 26.
Does California Lemon Law Cover Used Cars?
Yes, under certain conditions.
A used vehicle may qualify if:
- It is still covered by the manufacturer's original warranty, OR
- It was sold with a certified pre-owned warranty backed by the manufacturer.
If the vehicle was sold completely "as-is" with no manufacturer warranty, lemon law protections generally do not apply. This is one of the most common misconceptions consumers hold when buying used cars.
What to Do If You Think You Have a Lemon
Verify your warranty coverage. Confirm whether your vehicle is still under the manufacturer's original or CPO warranty.
Document every repair attempt. Save all repair invoices, service records, emails, text messages, and towing receipts. A strong paper trail is the foundation of any lemon law claim.
Use authorized repair facilities. Always give the manufacturer or authorized dealership the opportunity to repair the vehicle. Unauthorized repairs can complicate your claim.
Act quickly. Legal deadlines apply. New procedures introduced in 2025 under AB 1755 and SB 26 impose additional notice and filing requirements that affect California consumers.
