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.
Few things are more frustrating than driving off the lot in a new or newly purchased vehicle only to discover the windows won’t roll up or down. In California, problems present at delivery—like non-functional power windows—can fall under the state’s strong consumer warranty protections. This article explains, in plain language, how California’s Lemon Law may apply, what “non-functional at delivery” means for your rights, and practical steps you can take to protect yourself.
Non-Functional Windows at Delivery: Your Rights
Finding out your power windows don’t work right after delivery is more than an inconvenience—it can affect safety, comfort, and compliance with basic vehicle functions like defrosting or visibility in rain. Common causes include faulty switches, failed window regulators, blown fuses, wiring faults in the door harness, or a body control module issue. If the defect was present at or immediately after delivery, it’s important to document it right away.
In California, most new cars and many used or certified pre-owned vehicles are sold with a manufacturer’s express warranty. Under that warranty, the manufacturer must repair defects that arise during the warranty period, including issues that were present at delivery. A window system that doesn’t operate as designed can be a “nonconformity” with the warranty. You are generally entitled to warranty repairs at no cost, and every visit should be captured on a written repair order.
Take practical steps from day one. Note the issue on any “due bill” or “we owe” document at delivery, take photos or a short video showing the windows failing, and schedule an appointment with an authorized dealership service department. Save every repair order, parts receipt, and service text or email. Avoid DIY fixes or aftermarket modifications that could complicate diagnostics. Also check for recalls or technical service bulletins related to power windows—you can search your VIN on NHTSA’s website.
How California Lemon Law Applies and Next Steps
California’s Lemon Law (the Song-Beverly Consumer Warranty Act) can apply if the manufacturer or its authorized repair facilities can’t fix a warranty-covered defect after a reasonable number of attempts. If your windows were non-functional at delivery and the problem persists despite repeated repairs, you may have Lemon Law options such as a repurchase or replacement—though outcomes depend on the facts. The law also includes a “presumption” within the first 18 months or 18,000 miles if certain thresholds are met, such as multiple repair attempts for the same issue or 30+ cumulative days out of service. Whether non-functional windows are considered a safety-related defect can depend on the circumstances.
Your next steps are mostly about notice and documentation. Report the problem promptly, get the vehicle to an authorized dealer, and ask for detailed repair orders describing your complaint, the technician’s findings, and the work performed. Keep track of how many days your car is in the shop, and maintain a timeline. If the issue isn’t resolved, contact the manufacturer’s customer care line to open a case and follow up in writing. Some manufacturers use dispute resolution programs; participation may be optional, and timelines can vary.
If the defect keeps coming back or the vehicle is out of service for lengthy periods, it may be time to talk with a Lemon Law attorney. An attorney can review your warranty, repair history, and mileage to help you understand potential remedies and issues like the “mileage offset” and incidental expenses.
