When a brand-new 2024 Mercedes‑AMG S 63 E Performance won’t stay fixed, it’s frustrating, time-consuming, and potentially unsafe. California’s Lemon Law exists to protect consumers when repeated repair attempts don’t solve covered defects. Below, we explain how California’s rules apply to a high-performance, tech-heavy sedan like the S 63, common issues owners report, and practical next steps if your repairs keep failing—without legal jargon or unrealistic promises.
Is Your 2024 Mercedes-AMG S 63 a Lemon in CA?
California’s Lemon Law (part of the Song-Beverly Consumer Warranty Act) generally covers new and certain used vehicles sold or leased in California that are still under the manufacturer’s warranty. If Mercedes-Benz can’t repair a covered defect after a reasonable number of attempts, the law may require a repurchase, replacement, or another remedy, along with certain incidental costs. Every situation is unique, and qualification depends on facts like your warranty, the defect, and the repair history.
What counts as a “reasonable number” depends on the problem. California has a guideline called the Lemon Law presumption: within the first 18 months or 18,000 miles (whichever comes first), the vehicle is presumed a lemon if, for example, the same defect is subject to 4 or more repair attempts, a serious safety defect is subject to 2 or more attempts, or the car is out of service for repairs for a total of 30 or more days. You can still have a valid claim even if you’re outside those thresholds—these are guidelines, not hard limits.
For a 2024 AMG S 63 E Performance, qualifying defects are those that substantially impair use, value, or safety and are not the result of abuse or unauthorized modifications. Examples owners may encounter include persistent check-engine lights tied to the hybrid battery or power electronics, harsh or erratic shifting from the MCT transmission, active ride control or air suspension faults, brake regeneration/“blending” concerns, rear-axle steering or driver-assistance system malfunctions, electrical drain, or recurring MBUX/infotainment crashes. If the dealership can’t permanently fix a covered issue after multiple tries, it’s time to explore your rights.
What to Do If Repairs Keep Failing on Your S 63
Document everything. Each time you visit the Mercedes-Benz dealer, make sure your exact concern is written clearly on the Repair Order before you sign it, and keep copies of all work orders and invoices when you pick up the car. Track dates, mileage in/mileage out, loaner or rental receipts, towing charges, and days your S 63 is out of service. Photos or short videos of warning messages, noises, or symptoms can be very helpful.
Escalate the process. Ask the service advisor or manager to open a case with Mercedes-Benz USA and request involvement from a Field Technical Specialist if the issue persists. Ask whether there are Technical Service Bulletins (TSBs) or recalls related to your symptoms, and request that software updates or component replacements (not just resets) be considered where appropriate. If the car presents a safety risk, request a tow rather than driving it, and insist on a loaner or rental through your warranty benefits.
Learn your options and timelines. Manufacturers sometimes push consumers to use arbitration programs; whether that’s a good fit depends on your circumstances, and you are not required to accept any offer without understanding your rights. Strict deadlines may apply under California law, so don’t wait to get guidance. A California lemon law attorney can evaluate your repair history, warranty status, and goals, and in many successful lemon law cases the manufacturer may be responsible for reasonable attorney’s fees—meaning help can be accessible.
