Electric vehicles rely on software as much as hardware, and that means over-the-air (OTA) updates can make or break the driving experience. When those updates fail repeatedly—causing features to disappear, charging to stop, or safety alerts to light up—California consumers often wonder whether the state’s lemon law can help. This article explains how repeated OTA failures can fit into California’s lemon law framework and when it may be time to speak with a California lemon law firm like ZapLemon.
California Lemon Law and Repeated OTA Failures
California’s lemon law, part of the Song-Beverly Consumer Warranty Act, requires manufacturers to repair warranty-covered defects that substantially impair a vehicle’s use, value, or safety. That includes software-related issues in EVs, because software is integral to the operation of the car—covering everything from battery management and charging to driver-assistance features and the infotainment system. If a defect persists under warranty despite reasonable repair attempts, the law may entitle the consumer to remedies such as repurchase or replacement, depending on the facts and the law.
Repeatedly failing OTA updates can look like endless download loops, installation errors, or updates that complete but introduce new problems. Common EV complaints include disabled DC fast charging, sudden loss of range after an update, malfunctioning advanced driver-assistance systems (ADAS), blank instrument clusters, HVAC that won’t heat or cool, broken smartphone app connectivity, and vehicles that “brick” or won’t start after a software push. If these issues keep returning or cannot be fixed within a reasonable time, they may be considered nonconformities under warranty.
California’s lemon law includes a legal presumption that may apply within the first 18 months or 18,000 miles if certain thresholds are met—for example, multiple repair attempts for the same substantial defect or a vehicle being out of service for an extended period. The exact standards and how they apply depend on your situation, and timelines can be affected by whether repairs happen remotely or at a service center. Regardless of where the update occurs, you can help your case by documenting every failure, scheduling service visits when appropriate, and asking the dealer to open a repair order even for software issues addressed over the air.
When to Contact a California Lemon Law Firm
It may be time to contact a California lemon law firm when OTA updates repeatedly fail and leave you with the same unresolved problems under warranty, especially if the defects affect safety, charging, or the basic operation of your EV. Other red flags include long stretches waiting for a “future software fix,” being told the condition is “normal” when it clearly impacts use or safety, or multiple “unable to replicate” notations despite recurring issues. A firm can help you understand whether the pattern of failures and repair attempts fits California’s lemon law.
Before you reach out, gather the essentials: dates and version numbers of each OTA update, screenshots of error messages, photos or videos of the problem, and all repair orders—even for remote diagnostics or mobile service. Ask the dealer to document symptoms, attempted fixes, and any manufacturer technical service bulletins (TSBs) referenced. Keep a timeline showing when the vehicle was unavailable, and note any communications with the automaker’s customer care or case managers. These records help a lawyer evaluate your situation efficiently.
A California lemon law firm like ZapLemon can explain your options, communicate with the manufacturer, and help preserve important evidence. In some cases, the law allows consumers who prevail to recover reasonable attorney’s fees from the manufacturer, but outcomes vary and depend on specific facts. A consultation is the best way to understand how the law may apply to your EV, whether your issue stems from software alone, or a mix of software and hardware that updates haven’t resolved.
Repeated OTA failures aren’t just frustrating—they can undermine the core functions of an EV. If your vehicle’s software updates keep failing under warranty and the problems aren’t getting fixed, learning how California’s lemon law works can help you make informed next steps.
