If you drove off the lot and discovered your vehicle’s auto high beams don’t work—or they’re stuck on, flicker unpredictably, or throw error messages—you’re not alone. Modern headlight systems blend cameras, sensors, and software, and defects sometimes show up the moment you take delivery. In California, those early problems can raise important warranty and Lemon Law questions. Below, ZapLemon explains what to do first and how California’s Lemon Law may apply, all in plain English and without legal jargon.
Auto High Beams Dead on Delivery? Start Here
Finding a safety feature broken on day one is frustrating and unnerving. Auto high beams are designed to improve nighttime visibility by automatically switching between high and low beams, reducing glare for others and helping you see farther. When the system fails out of the gate, it’s more than a convenience issue—night driving may feel riskier, and you may question whether other advanced driver assistance systems are affected.
Start by documenting the problem. Take photos or a short video showing the behavior (e.g., the high beams won’t engage, a dashboard icon flashes, or an error appears in the instrument cluster). Note the date, mileage, weather conditions, and whether you were on a dark road—details can help technicians replicate the issue. If you still have your purchase/delivery paperwork, write the defect on any “due bill” or “we-owe” form you received from the dealer so it’s tied to the date of delivery.
Then book a warranty service appointment with an authorized dealership as soon as possible. Ask the service advisor to capture your exact concern on a repair order in your own words (for example: “Auto high beams do not activate at night on unlit highways”). Keep copies of all repair orders, invoices—even if the visit is “no charge”—and any texts or emails with the dealer. If your vehicle is in the shop, note the dates it’s out of service and whether you were given a loaner. Avoid DIY fixes (cleaning the camera lens and checking settings in the owner’s manual is fine), as modifications can complicate warranty coverage.
California Lemon Law Basics for This Lighting Defect
California’s Lemon Law (part of the Song-Beverly Consumer Warranty Act) generally applies when a new or warrantied vehicle has a defect that the manufacturer or its dealers cannot repair after a reasonable number of attempts, and the defect substantially impairs the vehicle’s use, value, or safety. The law can cover new cars and certain used or certified pre-owned vehicles that are sold or leased in California while still under the manufacturer’s warranty. What counts as “reasonable” depends on the facts, and there are special rules and presumptions that can help—but they are not automatic or one-size-fits-all.
How do auto high beams fit in? A nonfunctioning or malfunctioning auto high-beam system can affect nighttime safety and driver confidence. Dealers may try software updates, camera recalibration after windshield work, sensor or control-module replacement, or harness repairs. If repeated attempts don’t fix the problem—or the car spends significant time in the shop—you may be looking at a “nonconformity” under California law. The fact that the defect appeared at delivery can be important because it suggests the issue existed during the warranty period from the start.
If the Lemon Law criteria are ultimately met, potential remedies may include a manufacturer buyback (repurchase) or replacement vehicle, plus reimbursement of certain taxes, registration, and incidental costs. There may be a mileage-based offset for your use of the vehicle before the first repair attempt. Every case is different, results vary, and timelines depend on the specific facts, warranty terms, and the manufacturer’s response. A consultation can help you understand how these rules might apply to your situation.
If your auto high beams didn’t work from day one, don’t ignore it—document the problem, schedule warranty service promptly, and keep every repair record. California’s Lemon Law is fact-specific, and this article is for informational purposes only; it is not legal advice and does not create an attorney-client relationship.
