AB 1755 California Lemon Law: Evidence Checklist for a California Case

If you’re dealing with a stubborn vehicle defect in California, you’ve likely heard about the Song-Beverly Consumer Warranty Act (California’s Lemon Law) and may have seen news about AB 1755. This article explains, in plain language, what AB 1755 means in practice for your evidence and provides a simple, California-focused checklist of records to gather. It’s designed for information only and is not legal advice—if you need guidance about your situation, contact ZapLemon for a consultation.

What AB 1755 Means for Your Lemon Law Evidence

AB 1755 is part of ongoing efforts by California lawmakers to refine how consumer warranty claims, including lemon law disputes, are handled. While bill language can change during the legislative process, the takeaway for drivers is consistent: your paper trail matters. California’s Lemon Law already places a premium on documentation—proof of purchase or lease, warranty coverage, repair attempts, and time out of service. AB 1755, as it is discussed and updated, underscores the same theme: the stronger and clearer your documentation, the easier it is to show what went wrong and when.

In everyday terms, this means you should assume that every service visit, phone call, and email about your defective car matters. If your vehicle stalls, shudders, won’t start, loses power, shows warning lights, has recurring electrical glitches, or suffers EV battery/charging failures, document those symptoms with dates, mileage, and where it happened. California law looks at whether a defect substantially impairs the vehicle’s use, value, or safety and whether the manufacturer had a reasonable number of attempts to fix it or the vehicle was out of service for a significant amount of time. Clear evidence helps tell that story.

Importantly, AB 1755 doesn’t change the common-sense steps consumers can take now. Keep your purchase and warranty papers, save every repair order, and make sure the service advisor writes your complaint in your own words. If a dealer says “could not duplicate,” ask them to note the conditions when the issue occurs (speed, temperature, fuel/charge level, terrain). Photos, videos, and even screenshots of warning messages or charging-session logs for EVs can help. The goal is to create a clean, chronological record that shows the pattern of defects and repair efforts.

Checklist: Records to Gather for a California Case

Start with the foundation: your purchase or lease agreement, the retail installment sale contract (if financed), the warranty booklet (including any “lemon law rights” notice), and any extended service contracts. Add your registration, odometer disclosure, and title or lease-end paperwork. If you received recall notices, software update letters, or warranty extension notices, keep those too; they can help show the manufacturer knew of potential issues and what fixes were tried.

Next, collect repair documentation for every visit. You’ll want the full repair order and final invoice showing the date in, date out, mileage in, mileage out, customer complaint, diagnosis, and work performed. Keep loaner or rental car receipts, towing/roadside assistance records, and any parts or software update details. If you can, take photos or videos of warning lights, error messages, fluid leaks, vibrations, or infotainment glitches; for EVs and hybrids, save battery health reports, range screenshots, and charging-session logs. It’s also useful to note driving conditions when the problem appears (e.g., “brakes shudder downhill,” “loss of power after highway merge,” “ADAS warning after windshield replacement”).

Round out your file with communications and expense records. Save emails and texts with the dealer and manufacturer, note call dates and case numbers, and keep letters from any dispute programs or arbitration referenced in your warranty. Track out-of-pocket expenses tied to the defect, such as rideshare or towing, and keep a simple timeline listing each incident and repair attempt. Store everything in chronological order—both a digital folder (PDFs and photos) and a paper binder—so it’s easy to share during a consultation. Do not alter documents; if something looks inaccurate, ask the service department to correct and reprint it so the record stays clean.
