What Every Driver Should Know About the Song-Beverly Act

If you’re a California driver dealing with repeat car problems, you’ve probably heard about the Song-Beverly Consumer Warranty Act—better known as California’s Lemon Law. This law sets the ground rules for how manufacturers must honor warranties and what happens when a vehicle can’t be fixed after reasonable attempts. Below, we explain the basics in plain language and share practical tips to help you document repairs and protect your potential claim.

Song-Beverly Act Basics for California Drivers

At its core, the Song-Beverly Act requires manufacturers to repair a vehicle’s defects covered by an express warranty within a reasonable number of attempts. If they can’t fix a problem that substantially impairs the car’s use, value, or safety, the law may require the manufacturer to offer a repurchase (often called a “lemon buyback”) or a replacement vehicle. “Reasonable” depends on the facts, but common markers include multiple repair attempts for the same issue or the car being out of service for many days.

The law generally covers new vehicles and, in many cases, used or certified pre-owned vehicles that are still under the manufacturer’s warranty. It can also apply to leased vehicles and some small business vehicles, depending on weight and fleet size. Importantly, the problem must arise during the warranty period, and you usually need to give the manufacturer or its authorized dealer a reasonable opportunity to fix the issue.

Examples of qualifying defects range widely: transmission shuddering that won’t resolve, repeated check-engine warnings tied to drivability issues, infotainment systems that crash and disable backup cameras, brake defects causing vibration or extended stopping distances, air-conditioning failures in new vehicles, or recurring electrical problems that drain the battery. Safety-related defects—like steering loss, airbag problems, or brake failures—are taken especially seriously. While there’s a “presumption” that can assist consumers when defects occur early in ownership and after specific repair attempts or days out of service, vehicles can still qualify outside that presumption depending on the circumstances.

How to Document Repairs and Protect Your Claim

Good documentation is the backbone of any potential lemon law claim. Each time you visit the dealership, make sure the repair order clearly states your complaint in your own words, including the symptoms, frequency, and any dashboard warnings. Before you leave, get a copy of the repair order and the final invoice; these should show the dates, mileage in and out, and what the dealer did (diagnostics, parts replaced, software updates, test drives).

Keep a simple timeline: note the day the problem happened, when you dropped the car off, when you picked it up, and how many total days the vehicle was out of service. Save texts and emails with the dealer or manufacturer, and keep receipts for towing, rideshares, rental cars, hotels, or other out-of-pocket expenses related to the defect. Photos or short videos of the issue (for example, a screen freezing, warning lights, smoke, fluid leaks, or stalls) can be helpful—just record safely and legally.

A few practical tips: do not alter or modify the vehicle in ways that could complicate warranty coverage; follow the maintenance schedule and keep those records; and if the defect raises safety concerns, use caution and seek immediate service. If repairs keep failing, consider notifying the manufacturer directly in writing and asking for a final opportunity to repair—send it by a trackable method and keep copies. Manufacturer arbitration programs may be available; whether to use them is a strategic decision that’s best discussed in a consultation with a lemon law professional.
