If your 2020 McLaren 720S keeps returning to the service bay for the same issues, you’re not alone—and you’re not without options. California’s lemon law can offer strong protections when a covered defect repeatedly impacts a vehicle’s use, value, or safety while under the manufacturer’s warranty. This article explains common 2020 McLaren 720S problems California owners report and the basic factors that help determine whether your supercar might qualify as a “lemon” under state law.

Common 2020 McLaren 720S Defects in California
Owners of high‑performance cars like the 2020 McLaren 720S sometimes report electrical and software gremlins, which can show up as an unresponsive infotainment display, intermittent instrument cluster blackouts, keyless entry issues, or persistent warning lights. Some drivers also see malfunction messages tied to driver‑assistance sensors or chassis control systems. Door latch or window indexing problems on the dihedral doors can further complicate day‑to‑day use, especially if the issue recurs after multiple visits.
Powertrain complaints can include harsh or delayed shifts from the dual‑clutch transmission, “limp mode” activation, or drivability concerns like hesitation, misfires, or inconsistent turbo boost. Cooling system concerns—such as coolant leaks, overheating in traffic, or repeated temperature warnings—can lead to tow‑ins and extended time off the road. On the chassis side, owners sometimes mention suspension fault warnings, damper or hydraulic leaks, brake vibration or excessive noise, and steering feel irregularities that don’t resolve after service.
What matters for lemon law purposes isn’t that a model has a reputation for a certain flaw; it’s what’s happening with your particular car and warranty. Keep every repair order, note the dates your 720S is in the shop, and write down the symptoms you experience (what happened, when, how often, and how it affects driving). If a dealer references a technical service bulletin (TSB) or software update, ask for that to be noted on the repair invoice. Consistent documentation is often key evidence.
Does Your 2020 McLaren 720S Qualify in California?
California’s Song‑Beverly Consumer Warranty Act (often called the California Lemon Law) generally applies when a vehicle under the manufacturer’s warranty has a defect 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. It can cover new vehicles and, in many cases, used or certified pre‑owned vehicles still under the original or a manufacturer’s warranty. Exotic and high‑performance cars are not excluded simply because they’re specialty vehicles.
What counts as a “reasonable number” of repair attempts depends on the facts. California has a helpful guideline (a “presumption”) during the first 18 months or 18,000 miles: two or more repair attempts for a serious safety defect, four or more attempts for a non‑safety defect, or 30 or more cumulative days out of service can indicate a lemon. Importantly, even if you’re outside that 18‑month/18,000‑mile window, you may still have a claim if the defect arises and persists during the warranty period and the manufacturer had a fair chance to fix it. The key is that the problem is covered by warranty and meaningfully affects use, value, or safety.
If you’re evaluating your 2020 McLaren 720S, start by confirming warranty status and gathering your service history. Make a simple timeline showing each visit, the concern reported, what was done, and how long the car was out of service. Avoid modifying the vehicle while an ongoing defect is being diagnosed, communicate issues clearly with your service advisor, and request written copies of all repair orders. When the same issue keeps returning—or the car spends long stretches in the shop—consider speaking with ZapLemon about next steps, which can include seeking a repurchase (buyback), replacement, or other remedies available under California law. Results vary by case, and only a consultation can assess your situation.
