Lemon Car Lawyer for EV Power Loss

Electric vehicles are sophisticated machines, but repeated power loss, sudden “limp mode,” or shutdowns can turn a daily commute into a safety concern. If your EV keeps losing power under warranty and the dealer can’t fix it after multiple tries, California’s lemon law may offer remedies. This article explains EV power loss in plain language, how California’s Song-Beverly Consumer Warranty Act generally works, and the practical steps to document your repairs before contacting ZapLemon for a consultation.

EV Power Loss and California Lemon Law Basics

Power loss in EVs can look different from a traditional stall. You might feel abrupt reductions in acceleration, experience limited top speed, see warnings like “reduced power,” or lose propulsion entirely. Common causes include issues with the high-voltage battery, battery management system (BMS), inverter, on-board charger, drive unit, thermal management, or software that triggers safety derating. Sometimes the vehicle will enter limp mode on the highway or shut down after a rapid-charging session or during hot weather.

California’s lemon law, called the Song-Beverly Consumer Warranty Act, generally requires manufacturers to repair vehicles that have defects covered by warranty. If the manufacturer can’t fix a problem that substantially impairs use, value, or safety after a reasonable number of attempts, the consumer may be entitled to a repurchase, replacement, or other relief. What counts as “reasonable” depends on the situation, but repeated power loss, especially at speed, is often treated as a safety-related concern.

There’s also a “lemon law presumption” that can apply when certain repair attempts or days out of service occur within the first 18 months or 18,000 miles, whichever comes first. While these guidelines help frame the issue, they aren’t the only way to qualify, and every case is fact-specific. Keep in mind that EV components like batteries often carry longer warranties (for example, 8 years/100,000 miles), but the lemon law analysis focuses on whether warrantied defects were repaired within a reasonable time or number of attempts.

Steps to Document Repairs and Contact ZapLemon

Start with safety. If your EV loses power, pull over safely and call for a tow rather than driving a malfunctioning vehicle. Take quick notes about what happened: speed, state-of-charge, outside temperature, whether you were charging recently, dashboard warnings, and any noises or smells. Photos or short videos of warning lights or messages can help later.

At the dealership, clearly describe all symptoms and when they occur. Ask that your repair order include your complaint, the technician’s findings (cause), and the correction performed, plus dates and mileage in and out. Keep copies of every repair order, invoice, and recall or service bulletin, and note how long the vehicle is out of service. If the problem recurs, repeat this process and try to replicate the conditions that trigger the power loss so the technician can capture fault codes.

Maintain a simple file or digital folder with a timeline of events, including texts or emails with the dealer or manufacturer, tow receipts, and any app screenshots or telematics data showing faults. If the issue continues, consider sending written notice to the manufacturer and ask for a case number. Before taking any formal steps, contact ZapLemon for a consultation so we can review your records, explain your options under California law, and discuss next steps tailored to your situation.
