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.
Intermittent EV charging problems can be confusing, frustrating, and hard to prove—especially when your vehicle charges fine one day and refuses the next. At ZapLemon, we regularly hear from California drivers dealing with random charge drops, sessions that stop at 5% or 30%, or vehicles that won’t communicate with certain public fast chargers. Below, our lemon law team explains how California’s lemon law views intermittent charging issues and what you can do right now to protect your rights.
What Intermittent EV Charging Means Under CA Law
In everyday terms, an “intermittent” EV charging defect is a charging problem that comes and goes. Examples include your vehicle stopping charging unexpectedly, plugging in without initiating a session, or wildly fluctuating charging speeds across different Level 2 or DC fast chargers. Even if the problem isn’t constant, it can still be a defect if it affects the car’s use, value, or safety. For many EV owners, the inability to reliably charge is as serious as an engine that stalls.
Under California’s Song-Beverly Consumer Warranty Act (the “lemon law”), an intermittent issue may qualify if the manufacturer (through an authorized dealer) can’t fix a substantial defect after a reasonable number of repair attempts during the warranty period. California’s legal “presumption” offers guidance: generally four or more repair attempts for the same problem, two or more attempts for a defect likely to cause serious injury, or 30+ cumulative days out of service—occurring within the first 18 months or 18,000 miles. These numbers are not hard limits, but they help illustrate what courts may consider reasonable.
Charging defects can be tricky because they’re often blamed on third-party charging networks or conditions like temperature. Still, many EV charging faults are vehicle-side: communication module failures, onboard charger faults, thermal management issues that throttle or halt charging, software bugs, or battery management system errors. If the problem is on the vehicle side and the manufacturer can’t repair it within a reasonable opportunity, California’s lemon law may offer remedies. Because every case is fact-specific, a consultation is essential to assess your situation.
Steps to Take Before Calling a Lemon Law Lawyer
First, document the problem thoroughly. Keep a charging diary with dates, times, station brand/location, charger type (Level 2 or DC fast), reported kW, state of charge at plug-in, ambient temperature, and any error messages on the car screen or app. Save screenshots or short videos when a session fails or ends early. If your vehicle provides charging session logs through its app or telematics, download and preserve them.
Second, schedule repairs with an authorized dealer and clearly describe the symptoms. Ask that your work order includes your exact complaint (e.g., “DC fast charge stops at 12% with ‘charging error’ message”) and that the technician documents diagnostic trouble codes, software versions, and any firmware updates performed. Do not clear error messages or disconnect the 12V battery before service, because that can erase valuable data. After each visit, verify you received a detailed repair order and keep every page.
Third, check your warranty and any recalls or Technical Service Bulletins (TSBs). Many EV charging issues are covered by basic and powertrain warranties, as well as specific EV component warranties for the battery, battery management system, or onboard charger. If the problem persists, consider politely escalating with the dealer’s service manager or manufacturer’s customer care to ensure a complete paper trail. When you’re ready to talk with an attorney, having organized records—your diary, videos, and all repair orders—can make the evaluation faster and clearer.
