If you’re a 2025 Mercedes-Benz EQS owner in California and you’re dealing with repeat repairs, confusing software glitches, or persistent charging problems, you’re not alone. California’s lemon law may offer remedies in certain situations, and your factory warranty can play a big role in what happens next. This article explains how the California Lemon Law applies to the EQS and how to review your warranty so you can take informed, practical steps toward a resolution.
2025 Mercedes-Benz EQS Lemon Law in California
California’s Lemon Law—formally the Song-Beverly Consumer Warranty Act—protects consumers when a new or warrantied vehicle has a substantial defect that the manufacturer can’t fix after a reasonable number of repair attempts. It covers electric vehicles like the 2025 Mercedes-Benz EQS. In plain terms, if your EQS has a significant problem that affects use, value, or safety, and it keeps coming back despite authorized warranty repairs, the law may offer options such as a refund or replacement, depending on the facts.
California also has a “presumption” rule for new vehicles: during the first 18 months or 18,000 miles (whichever comes first), the law presumes a vehicle is a lemon if certain thresholds are met—such as two or more repair attempts for a defect that is likely to cause serious injury or death, four or more attempts for other substantial defects, or more than 30 cumulative days out of service for repairs. This presumption is a helpful guide, not a requirement; claims outside those limits may still qualify depending on the circumstances. Common EQS issues that owners report include charging system failures (AC or DC fast-charging faults), high-voltage battery warnings or shutdowns, repeated software or OTA update glitches that disable features, infotainment or instrument cluster blackouts, and driver-assistance sensor or calibration errors that persist.
If you’re experiencing any of the above, start with the basics: document every visit. Ask the service department to note your concerns in detail, include diagnostic codes, and provide a copy of each repair order showing dates and mileage in/out. Keep a simple timeline of symptoms, photos or video where possible, and note any towing or roadside assistance. Check for recalls or technical service bulletins (TSBs) that match your symptoms. Continue making your payments and maintaining insurance. If repeat issues persist, consider speaking with a California lemon law attorney to review your situation.

Review Your EQS Warranty: Coverage and Next Steps
Before deciding your next move, review your warranty booklet and the digital warranty information in your Mercedes Me account. The 2025 Mercedes-Benz EQS typically includes a New Vehicle Limited Warranty (often around 4 years/50,000 miles) and a separate High-Voltage Battery Limited Warranty that commonly extends longer (often up to 10 years/155,000 miles with capacity or defect terms). There may also be corrosion, emissions, roadside assistance, and software/OTA update provisions. Exact terms can vary, so rely on your specific documents and any California-specific coverage statements.
Warranties and lemon law work together. The defect generally must be covered by warranty and not caused by misuse or unauthorized modifications. You must give the manufacturer an opportunity to repair—so timely service appointments and accurate reporting of symptoms matter. “No trouble found” visits still count as part of your history, so keep those repair orders. If you purchased the EQS used but it’s still under the manufacturer’s warranty, California’s lemon law may still apply. In some cases, federal warranty law (the Magnuson-Moss Warranty Act) can provide additional remedies for repeated, unresolved warranty defects.
Practical next steps: schedule service promptly when problems occur, and describe symptoms the same way each time. Ask the advisor to include your words on the work order and to note all relevant software updates, parts replaced, and test results. If the issue returns, open a case with Mercedes-Benz USA and document your case number. Track total days out of service. If repeated defects substantially affect your EQS’s use, value, or safety, a consultation can help you understand your options under California law.
