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.
Slow charging can turn an electric vehicle from a daily convenience into a daily headache. If your EV routinely charges much slower than advertised or suddenly throttles to a crawl, you might wonder whether California’s Lemon Law can help. Below, ZapLemon explains how slow charging issues are evaluated under the law and what practical steps you can take to document the problem—without offering legal advice.
Does Slow EV Charging Qualify Under California Lemon Law?
California’s Lemon Law (the Song-Beverly Consumer Warranty Act) generally applies when a new or certified pre-owned vehicle has a defect covered by the manufacturer’s warranty that substantially impairs the vehicle’s use, value, or safety and the manufacturer can’t fix it after a reasonable number of repair attempts. In plain terms: if a covered problem keeps coming back and the dealer can’t get it right, you may have consumer remedies. Those remedies can include options like replacement or a refund; whether you qualify depends on your specific facts and the warranty.
How does that translate to EVs with low charging speeds? If your vehicle persistently charges far below what the manufacturer represents for your model and conditions, and that slow charging meaningfully disrupts daily use—long waits to “refuel,” missed appointments, or inability to complete normal trips—then it may be considered a substantial impairment. The analysis focuses on a vehicle-caused defect (for example, a faulty battery management system, on-board charger, thermal management, or software) rather than external factors like a weak public charger or cold weather.
California also has a “presumption” that can make it easier to show the manufacturer had a reasonable number of repair attempts if certain things happen within the first 18 months or 18,000 miles (whichever comes first). As a general example, the presumption may apply if: the same nonconformity was subject to repair four or more times; or a defect likely to cause death or serious bodily injury was subject to repair two or more times; or the vehicle was out of service for repair for a total of more than 30 days. These are examples only and not requirements—slow charging cases are very fact-specific, so a consultation is necessary to understand how the law might apply to your situation.
What to document if your EV charges painfully slow
First, get the issue evaluated by an authorized dealer or service center and keep every repair order. Ask that your complaint be written in your own words (e.g., “DC fast charging limited to 25 kW at 15% state of charge on multiple 150 kW stations”), and request copies showing the dates, mileage, diagnostic codes, software versions, parts replaced, and test results. Track how many days the vehicle is out of service and save emails or texts with the manufacturer or dealer about the problem.
Second, gather real-world charging evidence. Take photos or short videos during sessions showing the vehicle screen with charging power (kW), state of charge (SOC), battery temperature (if displayed), estimated time to full, and the charger’s posted rating (e.g., “150 kW”). Note the date, time, location, network (e.g., Electrify America, EVgo), stall number, ambient temperature, and whether you preconditioned the battery. Try multiple stations and networks on different days with the battery between roughly 10–60% SOC, since speeds normally taper at higher SOC; keep copies of station receipts or app logs showing delivered energy and average power.
Third, collect manufacturer materials and updates. Save the window sticker and owner’s manual pages that describe your model’s maximum DC fast-charging rate and on-board Level 2 charger rating (e.g., 11.5 kW). Keep a record of over-the-air updates or dealer software flashes and test charging again after each update; note any Technical Service Bulletins (TSBs) or recalls related to charging. Avoid modifications or aftermarket hardware while you troubleshoot. If the dealer road-tests charging, ask them to document results with a known-good charger and include screenshots or printouts in the repair file.
