If you’re driving a 2025 Mercedes-Benz EQS in California and dealing with repeat problems, you’re not alone. Luxury EVs combine complex software, advanced driver assistance, and high-voltage systems—meaning small glitches can snowball into persistent headaches. This article explains how California’s lemon law may apply to an EQS and what your warranty generally covers, so you can better understand your options.
We’ll keep things in plain English. You’ll find examples of common issues, what “reasonable repair attempts” means under California law, and practical steps to protect your rights—like keeping repair records and checking your warranty booklet. This is general information, not legal advice. If you need guidance on your specific situation, ZapLemon is here to help.
Whether your concerns involve software updates, charging problems, or warning lights that won’t quit, learning how lemon law and warranty coverage interact can make the next steps clearer. And if you believe your vehicle may qualify as a lemon, a consultation can help you understand your potential remedies.
Is Your 2025 Mercedes-Benz EQS a Lemon in California?
California’s Song-Beverly Consumer Warranty Act (the “lemon law”) can apply when a new vehicle has a defect covered by the warranty that substantially impairs its use, value, or safety—and the manufacturer or its authorized dealer can’t fix it after a reasonable number of attempts. There isn’t one magic number for every case, but California has a “presumption” that can make your claim easier to prove if problems occur within the first 18 months or 18,000 miles. In that window, the law presumes the vehicle is a lemon if, for example, the dealer made 2 or more repair attempts for a serious safety issue, 4 or more attempts for other issues, or the vehicle was out of service for repair for 30 or more cumulative days. Even if you’re outside those numbers, your EQS may still qualify depending on the facts.
With the EQS, we often hear about EV-specific concerns: fast-charging that suddenly slows or fails, repeated “malfunction” warnings for battery or drive systems, charging port or door faults, or software updates that trigger new error messages. Other examples include driver-assistance features (like Distronic or lane keeping) intermittently disabling, infotainment or MBUX glitches, HVAC heat pump performance swings, unusual electrical drain, shuddering under regenerative braking, or rattles and wind noise that persist after multiple attempts to fix. If your dealer keeps saying “cannot duplicate concern” or “operating as designed,” those visits still matter—keep every repair order.
Practical next steps: document each issue with photos or short videos when safe; open a repair order every time the problem appears; make sure the dealer accurately describes your concern (same symptom, same wording helps); and keep copies of all invoices, tow slips, and communications. If the vehicle sits at the dealership, note the dates. The more clear, consistent records you have, the easier it is to evaluate your lemon law options.

What Your 2025 EQS Warranty Covers in California
Your first stop should be the Mercedes-Benz Warranty Booklet that came with your EQS. Generally, Mercedes-Benz provides a New Vehicle Limited Warranty (often referred to as “bumper-to-bumper”) that covers defects in materials or workmanship for a set time/mileage, and a separate high-voltage battery warranty with a longer term. For recent EQ models, the high-voltage (HV) battery has typically been covered for up to 10 years/155,000 miles, often including a capacity retention threshold (for example, 70% when measured by the authorized test). Always confirm your exact terms, limits, and exclusions in the booklet for your model year and in any MBUSA updates.
What’s usually covered? Defects in Mercedes-Benz parts or factory-authorized software that cause a failure under normal use. What’s usually not covered? Routine maintenance, wear items (like tires and brake pads), damage from accidents or modifications, issues caused by non-approved accessories, and problems due to neglect or misuse. Software is increasingly important on the EQS—if an over-the-air (OTA) update causes a malfunction, that can still be evaluated as a warranty concern if it stems from a defect. California buyers may also benefit from certain state consumer protections layered on top of the manufacturer’s warranty, but the specific remedy depends on your facts.
How this ties into lemon law: the defect must be covered by the warranty, and the dealer must have had a reasonable number of chances to repair. If your EQS has been in the shop repeatedly for the same concern—say, repeated charging failures, persistent warning lights, or driver-assistance systems that disable themselves—ask the dealer to document each repair attempt clearly. Keep your own timeline, too. If you’re nearing the end of a warranty period, consider scheduling service promptly so your concern is on record. When in doubt, a quick review of your paperwork with a professional can clarify whether your situation might meet California’s standards.
