Start with the records. Repair orders, warranty documents, mileage, and days out of service are more useful than general assumptions about whether a vehicle qualifies.
Your new 2025 Mercedes-Benz EQB is supposed to deliver stress-free electric driving, not repeated trips to the service bay. If you’re dealing with charging failures, software glitches, or other recurring issues, California’s lemon law may offer powerful protections to help you protect your investment. This article explains how the law works in plain language, highlights common EQB trouble spots, and shares practical steps you can take right now—without giving legal advice.
Is Your 2025 Mercedes-Benz EQB a Lemon in CA?
California’s lemon law—formally the Song-Beverly Consumer Warranty Act—protects buyers and lessees when a new vehicle has defects that substantially impair its use, value, or safety and the manufacturer can’t fix those defects after a reasonable number of repair attempts. In everyday terms, if your EQB keeps having the same serious problem and the dealership can’t resolve it under warranty, you may have rights to a refund (buyback), a replacement, or other relief. The key is that the problem must be covered by warranty and not caused by misuse or unauthorized modifications.
California also includes a “lemon law presumption” for the first 18 months or 18,000 miles (whichever comes first). During this period, the law presumes a vehicle is a lemon if: (1) the manufacturer or dealer made 2 or more repair attempts for a defect that could cause death or serious injury, (2) 4 or more repair attempts for the same non-safety defect, or (3) the vehicle was out of service for repair for a total of more than 30 days. These are guidelines that help consumers—your EQB can still qualify outside the presumption window based on the facts.
If you suspect your 2025 EQB is a lemon, start by documenting everything. Keep copies of all repair orders, noting the dates, mileage, and specific symptoms (“DC fast charging stops at 40%,” “ADAS shut off mid-drive,” “vehicle won’t start after overnight charge”). Always take the vehicle to an authorized Mercedes-Benz service center, ask the advisor to record your complaint precisely, and verify that any software updates or technical service bulletins (TSBs) were applied. If problems persist, escalate with the manufacturer in writing and consider a consultation with a lemon law professional to understand your options.
Common EQB Defects, Repairs, and Warranty Tips
Because the EQB is an electric SUV, some issues owners report with EVs may be relevant: on-board charger faults, intermittent DC fast-charging sessions that stall or taper unexpectedly, home-charging communication errors, and sudden range drops possibly related to battery thermal management. Software can also be a pain point—infotainment or MBUX freezes, intermittent cameras, sensor miscalibrations, or driver-assistance features disengaging. Other commonly reported symptoms in modern EVs include 12-volt battery drains, HVAC/heat-pump performance complaints, squeaks/rattles, sunroof wind noise, and brake feel concerns when regenerative braking blends with friction brakes.
Know your warranty coverage. New Mercedes-Benz vehicles typically carry a new-vehicle limited warranty (often 4 years/50,000 miles) and a high-voltage battery warranty that can extend farther (commonly 8 years/100,000 miles, with specifics in your warranty booklet). Some emissions-related components may have separate California coverage. The exact terms for the 2025 EQB are in your owner’s materials—review them carefully so you know what’s covered, for how long, and which repairs must be performed by an authorized dealer.
Be proactive at the service visit. Clearly describe the problem, when it happens, and how to reproduce it (e.g., “Occurs after 30 minutes on DC fast charger,” “Happens on cold mornings,” “Warning appears at freeway speeds”). Ask the advisor to write your concern in your words, request the technician check for TSBs and software updates, and confirm any parts replaced. If the dealer says “no problem found,” ask them to note it in writing. Track all out-of-service days, towing, and rental or rideshare expenses—these records can matter later. Avoid aftermarket modifications that could complicate warranty coverage.
