If your car keeps going back to the shop for the same issues, you may be wondering whether it qualifies as a “lemon” under California law. Before a lemon car attorney takes your case, they look for clear signs that your vehicle’s problems meet specific legal criteria. The review is practical, document-driven, and focused on whether your situation fits the protections of the Song-Beverly Consumer Warranty Act (California’s Lemon Law). Below is an overview of what attorneys typically check, why it matters, and what you can do to prepare.
California Lemon Law Checklist: Initial Review
A lemon law attorney starts by confirming California coverage. They’ll look at where you bought or leased the vehicle, whether it was new or used, and whether there was a manufacturer’s warranty when the problems occurred. California’s Lemon Law can cover new vehicles and certain used vehicles that were sold with the manufacturer’s warranty still in effect. If the car was purchased out of state, used only for business, or heavily modified, the attorney will flag those facts because they can affect eligibility.
Next, they examine how the vehicle has been used and serviced. Was the car primarily for personal, family, or household use? Did an authorized dealership perform the repairs, and were those repairs requested while the vehicle was under the manufacturer’s warranty? If it’s a business-use vehicle, they’ll check two key limits: whether the gross vehicle weight rating is under 10,000 pounds and whether the business has five or fewer vehicles registered in California. They’ll also ask about accidents, aftermarket modifications, or missed maintenance, because these can complicate claims.
Finally, attorneys review your paper trail. The strongest cases have complete repair orders, dates the car was in the shop, a list of parts replaced, mileage in and out, and notes describing the complaint (for example, “transmission shudders at 30–40 mph,” “airbag light won’t turn off,” or “check engine light returns after a day”). They also note how many total days the vehicle has been out of service and look for timelines that may be relevant under the law. Practical tip: keep every repair order—even when the dealer “could not duplicate”—and store emails or texts with the dealer or manufacturer.
Song-Beverly Criteria: Defects, Repairs, Timelines
Under California’s Song-Beverly Act, attorneys assess whether a defect substantially impairs the vehicle’s use, value, or safety, and whether the manufacturer had a reasonable number of chances to fix it. “Substantial impairment” doesn’t mean the car is undrivable—it can also mean the vehicle is unreliable, unsafe, or worth less because of recurring issues. Common examples include persistent transmission slipping, electrical gremlins that drain the battery, repeated check engine lights, brake or steering problems, air conditioning failures during normal use, or repeated infotainment shutdowns.
They also look closely at repair attempts and days out of service. In many cases, multiple attempts for the same defect—or a long stretch of time when your car is in the shop—can support a lemon claim. California’s Lemon Law includes a “presumption” that may apply in the first 18 months or 18,000 miles if certain thresholds are met (for example, repeated attempts to fix the same substantial problem, two or more attempts for a serious safety issue, or 30+ total days out of service). Even if you’re outside the presumption window, an attorney can still evaluate your claim based on the overall repair history.
Timing matters. Attorneys consider when the problems began, whether they were reported during the warranty period, and whether the manufacturer was given a reasonable opportunity to repair. They also watch for factors that can limit or defeat a claim, such as damage from an accident, misuse, or non-warranty aftermarket modifications. Actionable tips: report issues promptly while under warranty, ask the dealer to precisely describe your complaint on the repair order, and keep a simple timeline of dates and mileage for each visit.
