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.
The 2025 McLaren 750S is a remarkable supercar, but even high-end vehicles can develop persistent issues. If your 750S spends more time at the dealer than in your garage, you may be wondering whether California’s lemon law can help. This overview explains what “lemon” means under California law, how it may apply to a 2025 McLaren 750S, and the practical steps you can take to protect your rights—without offering legal advice or making promises about results.
Is Your 2025 McLaren 750S a Lemon in California?
In California, the Song-Beverly Consumer Warranty Act (often called the California Lemon Law) protects buyers and lessees of vehicles covered by a manufacturer’s warranty. In plain terms, a car can be a “lemon” when a defect that’s covered by warranty substantially impairs the vehicle’s use, value, or safety, and the manufacturer or its authorized dealer cannot fix it after a reasonable number of repair attempts. The law can apply to new vehicles and, in some cases, used or Certified Pre-Owned vehicles that still carry the manufacturer’s warranty.
What does this look like with a 2025 McLaren 750S? Examples could include repeated dual-clutch transmission shuddering or failure to engage gears, engine misfires or overheating under normal conditions, hydraulic suspension leaks, persistent brake warnings or carbon-ceramic brake vibration that cannot be corrected, steering or active-aero faults, electrical gremlins like battery drain, infotainment freezes, or immobilizer/keyless start failures. One isolated glitch typically isn’t enough. What matters is a documented pattern of the same issue coming back—or extended time out of service—despite the dealer’s attempts to repair it.
California law doesn’t define “reasonable number” as a single fixed number, but there are helpful guidelines. A legal presumption may apply if, within the first 18 months or 18,000 miles, the vehicle has two or more repair attempts for a serious safety defect, four or more for a non-safety defect, or is out of service for 30 or more total days for warranty repairs. Even if you’re outside that “presumption” window, you may still have rights for the duration of the warranty. Potential remedies can include a manufacturer repurchase (buyback) or replacement, plus certain incidental costs—subject to a mileage offset and other legal rules. Every case is fact-specific, and outcomes are not guaranteed.
Steps to Take if Your 750S Has Repeated Defects
Start by documenting everything. Schedule repairs with an authorized McLaren dealer, and make sure the repair order clearly describes your complaint in your own words each time. Keep copies of all repair orders, invoices, and warranty communications. Track the dates, mileage, and number of days your 750S is out of service. Photos or videos of warning lights, leaks, or intermittent behavior can be helpful. Review your warranty booklet, and check for recalls or technical service bulletins that may relate to your issues.
Give the manufacturer a fair opportunity to fix the problem. If the defects continue, consider notifying McLaren in writing (such as certified mail) that the issue persists and you are requesting further repair or assistance under warranty. Avoid performance modifications while the car is being evaluated, since modifications and track use can affect warranty coverage. Continue making your loan or lease payments and maintain insurance; stopping payments can create separate problems unrelated to any lemon claim.
If the issues remain unresolved, many consumers choose to consult a California lemon law attorney to discuss options like repurchase, replacement, or other relief. An attorney can help evaluate timelines, repair histories, and next steps, including whether manufacturer arbitration is advisable in your situation. This page is for general information only—every situation is unique, and deadlines can apply under California law. Talking with a professional early can help you understand your choices without committing to any specific path.
Living with a high-performance car shouldn’t mean living at the service department. If your 2025 McLaren 750S has recurring defects that the dealer can’t fix, learning how California’s lemon law works is a smart first move. Keep thorough records, understand your warranty, and consider a consultation to get clear on your options.
