Finding missing parts after you’ve just driven home a new or certified pre-owned vehicle is frustrating. In California, those missing items can be more than an annoyance—they can affect your warranty rights and, in some cases, intersect with the California Lemon Law. This article explains how “missing parts at delivery” fits within California’s consumer warranty rules, what to document, and how to work with the dealer and manufacturer so you can protect your rights without turning it into a bigger headache than it needs to be.
California Lemon Law and Missing Parts at Delivery
California’s Lemon Law is part of the Song-Beverly Consumer Warranty Act. In plain terms, it requires manufacturers to fix defects covered by warranty that substantially impair a vehicle’s use, value, or safety. If they can’t repair the problem after a reasonable number of attempts—or the car is out of service for a significant time—you may have remedies such as a repurchase or replacement. While most people think of noisy engines or failing transmissions, a vehicle can also be “nonconforming” if it’s delivered without equipment or features that were promised and covered by the warranty.
“Missing parts at delivery” can range from small items (floor mats, cargo covers) to crucial items (second key fob, EV charging cable, jack kit, spare tire, wheel lock key, navigation SD card, software activation module, or even safety-related trim or fasteners). If the missing part keeps a feature from working as advertised or raises a safety concern, that nonconformity may fall under warranty obligations. The manufacturer typically must provide what was promised or make the vehicle conform to the written warranty and window sticker (Monroney label), buyer’s order, or advertised features.
Not every missing item will meet the Lemon Law threshold on its own. However, if the dealer or manufacturer can’t supply the parts or complete the fix after a reasonable number of attempts, or your vehicle is stuck in the shop waiting on backordered components for 30 or more cumulative days, it may begin to look more like a Lemon Law situation. For example, an EV delivered without its charging cable or a plug-in hybrid missing the charge port door assembly may substantially impair use or value. Similarly, missing safety-related hardware (like a seat headrest or child-seat anchor covers) could affect safety. The specifics matter, which is why consistent documentation and communication are important.
What to Do, Document, and Ask the Dealer Next
First, contact the selling dealer as soon as you notice parts are missing. Ask for a written “Due Bill” or “We Owe” listing each missing item, your VIN, and a target delivery date. Schedule a service visit so the dealer can open a warranty or parts-order file and generate a Repair Order—even if no work can be performed yet. Keep copies of everything: the sales contract, buyer’s order, window sticker, due bill, repair orders, text or email communications, and any photos or videos taken at delivery.
Create a simple timeline. Note the delivery date, the date you reported the missing parts, every visit to the dealer, and any days the vehicle was out of service. If the car is kept by the dealer while waiting for parts, ask for a loaner or rental reimbursement consistent with your warranty or manufacturer policies. If the missing component affects safety or drivability, ask the dealer to confirm in writing whether the vehicle is safe to operate until the part arrives. If a feature is disabled because an activation module or software code is missing, request that the concern be documented as a warranty nonconformity.
Be proactive with your questions. Ask the dealer: What is the exact part number? Is it on national backorder? What is the estimated arrival date and can they provide proof of ETA updates from the manufacturer? Can they issue a loaner if the car is inoperable or unsafe? Will they adjust or refund a dealer-installed accessory you paid for but did not receive? Request monthly written updates if there’s a delay. If progress stalls, open a case with the manufacturer’s customer care line and ask for a case number. Keep all correspondence, and consider learning about dispute resolution programs (like BBB Auto Line, where applicable) if the issue persists.
