Start with the records. Repair orders, warranty documents, mileage, and days out of service are more useful than general assumptions about whether a vehicle qualifies.
Modern cars are rolling computers, and when the electronics fail—infotainment screens freezing, phantom sensor warnings, cameras going black, or software glitches that kill power—daily driving can become frustrating or unsafe. California’s lemon law may cover these kinds of defects when they persist under warranty despite repair attempts. Below, ZapLemon explains how the law treats faulty vehicle electronics and what steps you can take to document problems with infotainment systems and sensors.
What California’s Lemon Law Covers for Electronics
California’s lemon law—often called the Song-Beverly Consumer Warranty Act—generally applies to new vehicles and many used or certified pre-owned vehicles that are still covered by the manufacturer’s warranty. Electronic components are treated like any other covered part. That includes infotainment head units, instrument clusters, backup cameras, Bluetooth and CarPlay/Android Auto, advanced driver-assistance systems (ADAS) like lane-keeping and adaptive cruise control, parking sensors, battery and charging software in EVs, and the modules and wiring that link all of these systems.
Coverage typically hinges on whether a defect substantially impairs the vehicle’s use, value, or safety, and whether the manufacturer (through its authorized dealer) has had a reasonable number of opportunities to repair it. California has a “presumption” period during the first 18 months or 18,000 miles, where certain repair thresholds can support a claim—for example, two or more repair attempts for a serious safety defect, four or more for the same non-safety defect, or more than 30 total days out of service for repairs. Even if your vehicle falls outside that window, you may still have rights; the presumption is helpful, but not required, to pursue a claim.
Electronics cases can involve unique proof issues. Intermittent failures, over-the-air (OTA) updates, and software patches count as repairs when performed under warranty and documented, but it’s important to keep records because the fix may be digital rather than a part swap. Aftermarket modifications and unauthorized coding can complicate coverage if they cause the problem, so disclose any add-ons. Potential outcomes under the statute can include repurchase, replacement, or a negotiated cash option when legal standards are met; however, results depend on the facts and require a legal consultation.
Steps to Document Defective Infotainment and Sensors
Start a clear paper trail. Each time the defect occurs, note the date, mileage, driving conditions, warning lights or messages, and what you experienced (e.g., “infotainment froze for 10 minutes; backup camera black; no audio; screen rebooted while driving”). Take short videos or photos showing the symptoms and any error screens. Keep a simple log on your phone, and back up your media. If the vehicle receives an OTA update or dealer software flash, write down the version number and date.
When you visit the dealership, describe the symptoms in your own words and ask that your description be written verbatim on the repair order. Request copies of all repair orders and final invoices every time—even for “no problem found.” Ask the service advisor to include software version numbers, technical service bulletin (TSB) references, and any diagnostic trouble codes pulled during testing. If the issue is intermittent, ask for a ride-along so a technician can observe it, and make sure the write-up notes that the problem happens sporadically and under what conditions.
