If your 2023 Mercedes-Benz EQB keeps going back to the dealer for the same problems, you’re not alone—and in California, you may have strong consumer protections. The state’s lemon law exists to address new vehicles with defects that don’t get fixed within a reasonable number of attempts while under warranty. Below, we explain how the California lemon law generally works for the EQB and how to document recurring defects so you can make informed next steps.
Is Your 2023 Mercedes-Benz EQB a Lemon in CA?
California’s lemon law (part of the Song-Beverly Consumer Warranty Act) generally applies to new vehicles with defects covered by the manufacturer’s warranty that substantially impair the vehicle’s use, value, or safety. The law typically requires that the manufacturer or its authorized dealer has had a reasonable number of opportunities to repair the problem. There is also a “presumption” window—often discussed as 18 months or 18,000 miles from delivery—where certain standards apply, such as multiple repair attempts for the same issue or the vehicle being out of service for an extended period. Even if you’re outside that window, you may still have rights, but the analysis can be more fact-specific.
What counts as a substantial defect varies. With an electric SUV like the 2023 EQB, issues owners commonly report across EVs can include charging failures (not accepting a charge or unexpectedly stopping mid-session), high-voltage battery warning lights, sudden loss of power or “limp mode,” range or state-of-charge inaccuracies, and software/infotainment glitches that affect screens, cameras, or driver-assistance features. Some drivers also experience HVAC performance problems, sensor faults, or persistent rattles and squeaks. Not every problem is a lemon law issue, but repeated, warranty-covered defects that materially affect your ability to use the vehicle can be relevant. It’s also wise to check for open recalls through NHTSA or the manufacturer.
If your EQB meets the legal criteria, potential remedies may include a repurchase (buyback) or a replacement vehicle from the manufacturer, as well as reimbursement for certain incidental expenses, subject to legal requirements and offsets. There are often dispute-resolution processes referenced in your warranty booklet, and timelines and procedures matter. Because every case turns on its own facts—number of repair attempts, days out of service, severity of the problem, and documentation—it’s important to get a personalized assessment before deciding how to proceed.
Steps to Document Recurring EQB Defects in California
Start by keeping a simple but thorough log. Each time the issue appears, note the date, mileage, driving conditions, outside temperature, battery state of charge, and what exactly happened (for example, “DC fast charge stopped at 38% with error message,” or “infotainment screen froze after start-up”). Take clear photos or short videos of warnings, messages, or symptoms when safe to do so. If a problem occurs during charging, jot down the station brand, location, and charger number, and save receipts or session summaries from your charging app.
When you visit the dealership, make sure each concern is written on the repair order exactly as you described it. Ask that the “customer states” section list your complaint, and that the dealer’s diagnosis and the parts or software updates performed are detailed on the final paperwork. Request and keep a copy of every repair order and invoice, even if the visit is “no problem found.” If the vehicle stays overnight or longer, ask the dealer to note the in/out dates, and save any loaner or rental car receipts—the total days out of service can be important.
If the defect returns after multiple repair attempts, or the vehicle is down for an extended period, consider escalating. Contact the manufacturer’s customer care line to open a case number, reference your repair orders, and keep notes of each call. Review your warranty booklet for any dispute-resolution program information. Because deadlines can apply and evidence matters, consider contacting a California lemon law attorney for a consultation to evaluate your options. Avoid making modifications to the vehicle during this process, and continue to document any recurring symptoms or software updates.
