You've been back to the dealership multiple times for the same issue. The repair never sticks. The problem returns within days or weeks. Sound familiar? If you're asking yourself whether your vehicle qualifies for California's lemon law, you're in the right place — and the answer may surprise you.

California's Song-Beverly Consumer Warranty Act casts a wide net. It covers more vehicle types, more defect categories, and more consumer situations than most people expect. But it also has specific requirements that need to be satisfied. This guide from The Blueprint Law Group covers exactly what qualifies — and just as importantly, what doesn't.

What Types of Vehicles Qualify?

Let's start with the vehicles themselves, because lemon law coverage is broader than just new cars off the lot.

New Vehicles: Any new car, truck, SUV, van, or motorcycle purchased or leased in California with an active manufacturer's warranty qualifies for consideration under the Song-Beverly Act. This is the most straightforward category.

Used Vehicles With Active Manufacturer Warranties: A used vehicle can qualify if it was sold with a manufacturer's express warranty still in effect at the time of purchase. If you bought a two-year-old car that still had one year remaining on its factory bumper-to-bumper warranty, and that car developed a recurring defect during that remaining warranty period, you have the same rights as a new car buyer.

Certified Pre-Owned Vehicles: Vehicles sold under a manufacturer-backed certified pre-owned (CPO) program are covered. The key word is manufacturer-backed — dealership-issued service contracts or third-party warranties do not trigger Song-Beverly protection.

Leased Vehicles: Lessees are fully protected under California's lemon law. The law doesn't distinguish between buyers and lessees. If you're leasing a defective vehicle, your rights are the same as if you had purchased it outright.

Small Business Vehicles: California extends lemon law protection to vehicles purchased or leased by businesses — provided the business owns five or fewer vehicles registered in California and the vehicle was purchased with a warranty. This is a frequently overlooked protection that applies to small business owners, contractors, and self-employed individuals.

Motorcycles: Motorcycles purchased for personal use with a manufacturer's warranty are covered under the Song-Beverly Act.

What's generally excluded: Off-road vehicles without street registration, boats, aircraft, and motorhome living quarters (the habitation portion) fall outside the Act's coverage. Vehicles purchased in other states are also generally not covered.

What Types of Defects Qualify?

This is where consumers most often underestimate their rights. The law doesn't provide a specific list of qualifying defects — instead, it uses a legal standard: the defect must be a nonconformity that substantially impairs the vehicle's use, value, or safety.

That standard applies broadly. Here are the categories of defects that regularly qualify:

Powertrain Defects: Engine and transmission problems are among the most common qualifying defects. Persistent misfires, stalling, excessive oil consumption, overheating, rough idling, delayed shifts, gear slipping, or complete transmission failure all fall squarely within the law's reach.

Electrical System Failures: Modern vehicles are heavily reliant on electronics. Defects affecting the instrument cluster, infotainment system, power windows and locks, charging systems, battery management, or sensor networks can qualify — particularly when they affect the vehicle's core functions or create safety risks.

Brake System Defects: Any recurring issue with the braking system is taken seriously under lemon law. Brake fade, a soft or spongy pedal, ABS malfunctions, uneven braking, and premature brake wear despite normal driving conditions can all qualify.

Steering Problems: Loss of power steering, persistent pulling to one side, vibration in the steering wheel, or steering system noise that recurs after repair are qualifying defects, particularly because of the direct safety implications.

Safety System Malfunctions: Failures in airbag systems, lane departure warning systems, automatic emergency braking, blind spot monitoring, and other advanced driver assistance systems (ADAS) are among the most compelling qualifying defects — especially when the manufacturer can't isolate or repair them.

Battery and Charging Issues in EVs and Hybrids: With California's large electric vehicle population, battery defects are increasingly common in lemon law cases. Significant range reduction beyond normal degradation, charging failures, battery management system errors, and thermal management defects can all qualify.

Persistent Warning Lights: When a check engine light, oil pressure warning, or other warning indicator repeatedly illuminates — and the dealership cannot identify a root cause after multiple attempts — that recurring diagnostic failure itself can support a lemon law claim.

Body and Structural Defects: Water intrusion, wind noise, rattles, and structural issues that recur after repair and affect the vehicle's value or daily use can qualify, though these cases require more careful legal analysis than mechanical defects.

What Doesn't Qualify?

Being honest about exclusions is important. These situations generally fall outside the law's protection:

• Defects caused by owner misuse, neglect, or failure to follow maintenance schedules
• Damage from collisions, floods, or accidents unrelated to a manufacturer defect
• Problems resulting from unauthorized modifications or aftermarket parts
• Minor cosmetic issues that don't affect function, safety, or resale value
• Defects first reported after the warranty expired
• Issues covered only by a third-party or dealer-issued warranty, not a manufacturer warranty

Even in borderline situations, it's worth consulting an attorney before assuming your vehicle doesn't qualify. Manufacturers sometimes try to blame consumers for defects that are actually design or manufacturing flaws — and an experienced lemon law attorney knows how to counter those claims.

What Repair Thresholds Must Be Met?

Meeting the legal threshold for repair attempts is what converts a 'defective vehicle' into a lemon law claim. California's Song-Beverly Act provides a rebuttable presumption that a vehicle is a lemon when the following thresholds are met within 18 months of delivery or 18,000 miles — whichever comes first:

• Four or more repair attempts for the same nonconformity that still exists
• Two or more repair attempts for a nonconformity likely to cause serious injury or death
• Cumulative out-of-service days exceeding 30 days for warranty repairs

Two critical points consumers often miss: First, the 30-day out-of-service calculation is cumulative across all related repair visits — not just a single repair attempt. A vehicle that spent 10 days in the shop in January, 12 days in March, and 9 days in June has now exceeded 30 days. Second, every repair attempt must be performed by the manufacturer's authorized service center. An independent mechanic's work does not count.

Outside the 18-month and 18,000-mile window, claims can still be pursued within four years of discovering the defect, but the legal presumption of lemon status no longer applies automatically. Your attorney will need to build the case from the evidence rather than relying on the presumption.

What If the Dealer Says 'No Problem Found'?

This scenario — the 'no problem found' or 'unable to duplicate' result — frustrates countless California consumers and leads many to believe they have no claim. That's not true.

Under California lemon law, a visit to the dealership where the technician cannot replicate the defect still counts as a repair attempt in many circumstances. The fact that the dealer repeatedly fails to diagnose or resolve a defect you're consistently experiencing is itself evidence of the vehicle's nonconformity.

The critical step is ensuring you describe the defect as specifically as possible on each visit. Don't say 'something is wrong with the car.' Say 'the transmission hesitates and shudders when accelerating between 25 and 40 mph, occurring approximately three times per week in moderate traffic.' Specific, documented complaints create a paper trail that an attorney can work with — even when the technician's repair order says no problem was found.

The Role of Technical Service Bulletins

A Technical Service Bulletin (TSB) is a notice issued by the manufacturer to its authorized dealers that describes a known defect and provides repair instructions. TSBs are one of the most powerful pieces of evidence in a lemon law case because they demonstrate that the manufacturer was aware of a widespread defect affecting your vehicle's make, model, and year.

When a TSB exists for your vehicle's issue and the dealer has still failed to fix it after multiple attempts, it significantly strengthens your claim. TSBs are searchable through government databases and manufacturer records. A lemon law attorney will check for TSBs related to your vehicle's defect as part of the case evaluation process.

How Soon Should You Act?

California's lemon law has a four-year statute of limitations that runs from the date you discovered — or reasonably should have discovered — the defect. While four years may seem like a long time, waiting erodes your claim in practical ways:

• Repair orders and service records can become harder to obtain
• Vehicle mileage increases, which may affect the mileage offset calculation in a buyback
• Evidence of the defect may become less clear over time
• The vehicle may exit the warranty period, complicating the claim

The moment you suspect your vehicle may qualify as a lemon, consulting an attorney costs you nothing and could preserve your right to a full remedy.
