California Lemon Law for Poor EV Range Performance

Electric vehicles promise low maintenance and smooth driving, but poor real-world range can turn ownership into a daily headache. If your EV can’t reliably reach the miles you were told to expect—and the dealer can’t fix it—California’s lemon law may come into play. Below, we explain how California law treats persistent EV range issues and what steps you can take to protect your rights.

Poor EV Range? How California Lemon Law Applies

California’s lemon law (the Song-Beverly Consumer Warranty Act) protects consumers when a vehicle has a defect that the manufacturer can’t repair within a reasonable number of attempts while the vehicle is under warranty. The law applies to new vehicles and many used vehicles that are still covered by a manufacturer’s warranty. For EVs, “poor range” may qualify if it stems from a defect that substantially impairs the car’s use, value, or safety—not just normal range variation.

Range problems can have many causes. Normal factors like cold weather, high speeds, steep hills, and heavy loads will reduce range and are not defects by themselves. But persistent issues such as rapid battery capacity loss beyond the warranty’s promise, a malfunctioning battery management system that misreports state-of-charge, thermal management failures that limit power, or software updates that permanently reduce range may indicate a nonconformity the manufacturer must address.

California’s “lemon law presumption” may apply if, within the first 18 months or 18,000 miles, the vehicle has (a) four or more repair attempts for the same problem, (b) two or more attempts for a problem likely to cause serious injury or death, or (c) 30 or more cumulative days out of service. Even if you’re outside that window, the law can still apply during the warranty period—it just won’t be presumed. Remedies under the statute can include repurchase or replacement in appropriate cases, but outcomes depend on the facts of each situation and cannot be guaranteed.

Document Repairs and Contact ZapLemon for Help

Thorough documentation is critical. Each time range problems surface, note the date, mileage, weather, terrain, driving speed, starting and ending state-of-charge, and actual miles achieved. Save photos of the dash, route summaries, and charging session data. When you visit the dealer, describe symptoms in plain terms (for example, “Vehicle shows 240 miles at 100% but consistently achieves 120–140 miles in mild weather at 65 mph”), and ask for a detailed repair order every time, including software versions, diagnostic codes, and any battery “state of health” measurements the manufacturer provides.

Ask the service department about technical service bulletins (TSBs), recalls, or software updates related to range, charging, or battery management. If the dealer says “operating as designed,” request that statement in writing on the repair order. If the problem recurs, schedule additional visits and keep all records, including emails and texts with the dealer or manufacturer. Many EV batteries carry 8-year/100,000–150,000-mile warranties with capacity-retention promises, but terms vary—check your warranty booklet to learn what standard applies to your model.

If you’re dealing with repeated range shortfalls or unresolved EV battery issues, consider speaking with a California lemon law attorney.
